Page 60 MMMMMM MM MMMMM MMM MMMMMMM PMMjMMM FMMM MMMMMMMMM Scan projects are often composed of several subprojects. For example, a scan of the interior of a multi-floor building can be organized into subprojects – one subproject for each level of the building. Each of these Slide 44 subprojects can be organized into subprojects representing each room on each floor of the building.
Page 61 LMMMMM 2M MMMMMMM MMfMLMMM MMMMMMM FMMM MMMMMMMMM The easiest way to create this file structure on the scanner is to add subprojects and let the scanner automatically name each subproject and each scan. The scanner’s automatic naming uses consecutive numbers, Slides 45-49 periods, and underscores.
Page 62 MMMMMM MM MMMMM MMM MMMMMMM To view subprojects on the scanner, select the project that contains the subprojects. MMMMMM > PMMjMMMM When you view the scans (by tapping View Scans), you can see that each scan is also numbered consecutively, beginning with 0.

Page 67: Scan Parameters
LMMMMM 2M MMMMMMM MMfMLMMM MMMM PMMMmMMMMM Scan parameters are settings that affect the captured data and the scan duration. Slide 51 To understand how scan parameters will affect the captured data, it is important to understand how the scanner works. LML MMM MMMMMMM WMMkM Laser scanners emit laser light, which is reflected off of surfaces in the scan area, and then reflected back to the scanner.
Page 68 MMMMMM MM MMMMM MMM MMMMMMM TMmM-Mf-FMMMMM MMMMMMMmMMM Time-of-flight scanners measure the amount of time it takes for the emitted laser light to return to the scanner, and use that time to calculate distance. Slide 53 TMmM Mf FMMMMM MMMMMMMmMMM PMMMM-BMMMM MMMMMMMmMMM The Focus uses phase-based measurement.
Page 69 LMMMMM 2M MMMMMMM MMfMLMMM PMMMM-BMMMM MMMMMMMmMMM Phase Shift RMmMvMMM AmbMMMMMy When the phase difference of laser light is measured, there is some ambiguity, because the location of the phase can vary periodically. This means that the phases of the emitted light and the returning light may align perfectly, so the phase shift distance measurement is zero.
Page 70 MMMMMM MM MMMMM MMM MMMMMMM MMMMM/MMMp PMMMM When scanning, a laser light is sent from the scanner onto the mirror, which reflects the laser outward. Slide 56 Reflected Laser The mirror rotates around a horizontal axis, and the scanner rotates around a vertical axis.
Page 71 LMMMMM 2M MMMMMMM MMfMLMMM The start/stop point is where the scan starts and stops on the horizontal axis. The start/stop point of the scanner is located at the center of the scanner, in line with the power inlet and perpendicular to the front of scanner.
Page 72 MMMMMM MM MMMMM MMM MMMMMMM PMMMM DMMMMMMM Because the laser light is sent from a single point (the center of the mirror), the distance between the captured scan points increases with distance from the scanner. This distance, called point distance, is also referred to as point density.
Page 73 LMMMMM 2M MMMMMMM MMfMLMMM CMmmMM MMMM PMMMmMMMMM Scan Parameters are used by the scanner when recording scan data. You can set these parameters to ensure you have enough scan data to meet project requirements, are working within any time constraints, and are Slide 61 able to successfully register scans together.
Page 74 MMMMMM MM MMMMM MMM MMMMMMM RMMMMMMMMM The Resolution setting determines the point distance, which, in turn, determines the level of detail. Slide 63 TMbMMMMp (LML RMMMMMMMMM) TMbMMMMp (LMMM RMMMMMMMMM) Focus X 130 and X 330 • SCENE 5.3 September 2014...
Page 75 LMMMMM 2M MMMMMMM MMfMLMMM Increasing the Resolution setting increases the number of points captured and decreases the point distance. Decreasing the Resolution setting decreases the number of points captured and increases the point distance. You can adjust the Resolution setting to capture more points on distant objects.
Page 76 MMMMMM MM MMMMM MMM MMMMMMM QMMMMMy With a higher Quality setting, the scanner captures points that are more concentrated on objects in the scan area. The Quality setting affects the rate of measurement, the level of noise reduction, and the range of the Slide 65 scanner.
Page 77 LMMMMM 2M MMMMMMM MMfMLMMM The Quality setting also employs noise reduction, an algorithm used to determine whether differences in scan points are an accurate representation of detail, or noise (extraneous unwanted points). The algorithm compares scan points within a specific distance of one another and determines if the difference is within the tolerance specified by the Quality setting.
Page 78 MMMMMM MM MMMMM MMM MMMMMMM MMMM LMMM CMMMM When Scan with Color is on, the scanner takes color photographs of the scan area after capturing the scan data. The scanner makes an additional rotation and captures approximately 85 photographs per scan. The color information can be applied to the scan data in SCENE.
Page 79 LMMMMM 2M MMMMMMM MMfMLMMM AppMMMM CMMMM Slide 68 Scan Profiles Resolution and Quality settings, detail scan settings, the color setting, and other settings can be saved as a scan Profile. To select a profile, from the Home screen, tap Parameters > Selected Slide 69 Profile.

Page 97: Registration
LMLLMM MM RMMMLMMMMMMM LMLLMM MM Registration This lesson explains the basic concept of registration. Understanding Slides 88-90 registration allows you to plan scan projects to ensure efficiency and success. While some scan projects require only a single scan, creating a three- dimensional image requires multiple scans.

Page 101: Common Reference Objects
LMLLMM MM RMMMLMMMMMMM LMmmMM RMfMMMMMM ObMMMML Common reference objects are objects common to two or more scans. Common reference objects are used to align the scans during registration. Slide 96 There are two main types of common reference objects: • Artificial common reference objects (targets) •...
Page 102 MMMMMM MM MMMMMMM MMMMMMMM Common types of targets include: • Checkerboards – Flat, paper targets that can be printed in various sizes. The advantages of checkerboards are they are portable and disposable, and can be printed in various sizes. They also require fewer scan points to be recognized in SCENE, and can be placed farther from the scanner.
Page 103 LMLLMM MM RMMMLMMMMMMM LphMMM Circular Flat Target Checkerboards Checkerboards can be printed as they are needed, and are inexpensive. They can also be printed in a larger size, which allows you to place them farther from the scanner and still be recognized as checkerboards. You can number checkerboards, which makes it easy to identify which checkerboards correspond to one another.
Page 104: Natural Common Reference Objects
MMMMMM MM MMMMMMM MMMMMMMM Be sure to print checkerboard targets with laser printers, rather than inkjet printers, because the reflectivity of checkerboards printed with inkjet printers can cause problems. Laminating checkerboards can also cause problems due to reflectivity. If you do laminate checkerboards, be sure to use a matte laminate and test the targets before use.
Page 105: Correspondence
LMLLMM MM RMMMLMMMMMMM NMMMMMM LMmmMM RMfMMMMMM ObMMMM (MMMMM MM LMMM M) LMMMMLpMMMMMMM A correspondence is the relationship between the same common reference object in multiple scans. To register scans, you need to be able to identify the same object in two or more scans. SCENE uses these Slide 99 objects, (common reference objects), to create correspondences.
Page 106: Reference Scans
MMMMMM MM MMMMMMM MMMMMMMM RMfMMMMMM LMMML During registration, SCENE aligns all scans to a single scan, called a Reference Scan. All of the scans included in the registration are aligned to the coordinates of the Reference Scan. In addition, the sensor data, Slide 101 such as the Altimeter data, for all scans is factored into the registration relative to the sensor data of the Reference Scan.

There are several factors to consider when selecting scanner positions, including: •...
Page 108 MMMMMM MM MMMMMMM MMMMMMMM The primary factor when determining distance from the scanner is Point Distance. Increasing the Resolution setting decreases the Point Distance (increasing the point density), which allows the scanner to be positioned farther from the object or area of interest, and increases the Scan Duration.

Page 114: Target Arrangements
MMMMMM MM MMMMMMM MMMMMMMM Target Arrangements Even if you plan on using targetless registration, it is recommended that you use targets in your scan project to give you more options for ensuring successful registration. Position the scanner so targets can be Slide 116 arranged in overlapping scan areas.
Page 115: Lesson
LMLLMM 4M TMMMMM AMMMMMMmMMML LMLLMM 4M Target Arrangements This lesson explains the importance of target arrangements, which Slides 117-119 include target placement and target mounting. Arranging and mounting targets carefully ensures you are able to register scans successfully. The arrangement of the targets in relation to one another and in relation to the scanner position is critical to the registration process.
Page 116: Distance From The Scanner
MMMMMM MM MMMMMMM MMMMMMMM However, using too many targets can add confusion and make it difficult to identify which targets correspond to one another. DMLMMMMM fMMm MhM LMMMMMM The distance that a target can be placed from the scanner depends on many factors.
Page 117: Line Of Sight
LMLLMM 4M TMMMMM AMMMMMMmMMML Increasing the Resolution setting and the size of the target increases the number of points captured on the target. Increasing the Resolution setting also increases the Scan Duration; it may be better to place the target closer to the scanner. For example, given a Quality setting of 4x, Scan with Color off, and a 140-mm-diameter sphere, the following maximum distances are generally recommended:...

Page 122: Height
MMMMMM MM MMMMMMM MMMMMMMM HMMMhM Ensure that the targets are arranged in unique patterns in three dimensions by varying the height of the targets. You can vary the height using surfaces in the scan area, such as tabletops, or by other means, such as tripods.
Page 123 LMLLMM 4M TMMMMM AMMMMMMmMMML LMMMMMhM-LMMM MMMMMMM When creating unique target arrangements, be sure not to arrange targets in a straight line. When targets are placed in a straight line, the line acts as an axis during registration. The scans can align around the axis in an Slide 130 infinite number of ways.

Understanding and practicing scanning strategies allows you to adapt the elements of each strategy to individual scan projects.
Page 138: Central Object Of Interest
MMMMMM MM MMMMMMM MMMMMMMM LMMMMMM ObMMMM Mf IMMMMMLM The Central Object of Interest strategy involves arranging targets and positioning the scanner around the object of interest. Slide 150 Because the object of interest is centralized, the scanner has a clear line of sight to most, if not all, of the targets.
Page 139: Central Targets
LMLLMM 5M LMMMMMMM LMMMMMMMML Central Targets The Central Targets strategy involves arranging targets in the center of the scan area and positioning the scanner around the targets. Slide 151 With this scanning strategy, all of the scans are registered using the same group of targets.
Page 140: Central Reference Scan
MMMMMM MM MMMMMMM MMMMMMMM LMMMMMM RMfMMMMMM LMMM The Central Reference Scan strategy involves capturing a central reference scan and arranging targets and positioning the scanner around the initial reference scan. Slide 152 LMMMMMM RMfMMMMMM LMMM LMMMMMMy Traversing Strategies Traversing strategies involve moving targets from one scan area to another, and linking adjacent scans with targets arranged in the overlapping scan areas.
Page 141: Open Traverse
LMLLMM 5M LMMMMMMM LMMMMMMMML Open Traverse The Open Traverse strategy involves linking each scan to the previous scan by moving targets. Slides 154-156 It is best to begin by planning target arrangements and scanner positions for the first three scans. First, identify the overlapping scan areas, based on the maximum distance, as determined by the Resolution setting.
Page 142 MMMMMM MM MMMMMMM MMMMMMMM Before capturing the third scan, identify the overlapping areas between the third and fourth scans, and move the first group of targets to that area. Do not move the second group of targets, which is between the second and third scans.
Page 143 LMLLMM 5M LMMMMMMM LMMMMMMMML Capture the fourth scan. Continue identifying overlapping scan areas and moving the groups of targets as needed. Open Traverse Strategy – All Scans ±4 ±2 ±6 ±2 ±8 ±4 ±8 ±8 ±6 Focus X 130 and X 330 • SCENE 5.3 September 2014...
Page 144 MMMMMM MM MMMMMMM MMMMMMMM EMMMM During registration, SCENE designates the first scan as the reference scan, and all subsequent scans are aligned to this reference scan. Each scan position contains a small amount of error (±2 mm), and this error accumulates with each subsequent scan.
Page 145: Closed Traverse
LMLLMM 5M LMMMMMMM LMMMMMMMML Closed Traverse The Closed Traverse (or Closed Loop) strategy involves adding an additional step to the Open Traverse strategy and linking the first and last scans. Slides 158-159 To begin, identify the overlapping scan areas between the first scan and the last scan.
Page 146 MMMMMM MM MMMMMMM MMMMMMMM Then plan target arrangements and scanner positions for the first three scans. Continue with the Traversing strategy. Closed Traverse Strategy – All Scans Focus X 130 and X 330 • SCENE 5.3 September 2014...

Page 148: Targetless Strategy
MMMMMM MM MMMMMMM MMMMMMMM Targetless Strategy To ensure there is enough overlap between scans, you will need to take more scans than for Target Based registration. While this adds time to the scan project, the fact that you don’t need to arrange and move targets also saves time.
Page 149 LMLLMM 5M LMMMMMMM LMMMMMMMML Use this strategy when a smaller, high-resolution scan needs to be captured within a larger context. DMMMMM wMMh MM OvMMvMMw LMMMMMMy This strategy will be discussed in more detail later in the training. Focus X 130 and X 330 • SCENE 5.3 September 2014...
Page 150: Examples
MMMMMM MM MMMMMMM MMMMMMMM ExMmpMML Seeing real-world examples of different scanning strategies can help you decide what strategies might work for you. IMMMMLMMMMMM ExMmpMM L This is a simple layout because each target is visible from every scanner position. However, it is made more complicated by the fact that the crew must stay out of the road.
Page 151 LMLLMM 5M LMMMMMMM LMMMMMMMML IMMMMLMMMMMM ExMmpMM M In this example, a higher Resolution setting is required to adequately capture the targets.

Page 331: Accuracy Verification
AAAAAAAA 2A AAAuAaAA VAAAA AaAAoA AAAAAAAA 2A Accuracy Verification In some fields, such as law enforcement, verifying the accuracy of the scanner to a reasonable degree of certainty, referred to as an accuracy confirmation check, is critical. This can be done using scale objects. SAalA ObjAAAA Scale object are objects such as rulers, yardsticks, or any accepted standard measurement indicator.
Page 332 AAAAAAAAAA • The scale object is placed close enough to the scanner so that the measurement units can be adequately captured and are readable. Each situation will call for different types of scale objects and different placements, based on factors such as whether the scan is indoors or outdoors, the types of scale objects available, etc.
