Page 36 The device tracks its position based off what it has seen before. Transitions When moving into a new area, between take the transition very slowly so that the device has enough rooms opportunity to connect new things it sees to the old stuff it has already seen.
Page 37 Scan Path SLAM tracks your motion through a space, so you can walk in a straight line or do ‘S’ like patterns through a space.
Page 38 It might seem silly but it helps Pretend Make wide turns whenever you are possible. This ensure that quick pivots do not cause tracking loss a truck and broken scans.
Page 39 Plan your route While preparing to go on site, make sure you think about the way you want to scan. Any prep work you can do to make sure your route is understood and managed will improve your scanning experience. Below is an example of a small site that we planned out.

Page 51 Paracosm SLAM tracks the motion of the device as you walk around a space. The tracking is frame to frame, so we track where you are going based on where you just were. This tracking is very accurate when When loop in wide open spaces, because there are many common features.
Page 52 Environments to scan in loops: Any environment where you travel a long linear distance from the beginning without seeing many commons features, eg: ○ Long winding hallways When loop ○ Multiple city blocks Tunnels ○ Warehouses with dense rows ○ closure helps: Environments where loop closure may NOT be needed:...
Page 53 Criteria to detect and close a loop: scans due to tracking loss. Moving the ● Loops are detected from the geometric PX-80 slowly into new areas (rooms, features captured from the LiDAR. Need similar position in an environment with doorways, hallways) will improve the similar FOV to detect a loop.
Page 54 ● Have as large of a common field of view as possible (wide open area is better Tips & Tricks for a loop, than a smaller enclosed space) ● Geometric uniqueness is better for detecting loops (lots of edges and corners are recommended over simple geometry)

Page 61 Hold horizontal for good horizontal coverage. If you have a narrow hallway with a sharp corner, horizontal position might provide the best tracking. Angles for To get more floor & ceiling coverage, angle the scanner forward. This captures the floor in front of you and the ceiling behind you.
Page 62 Angles for the FOV Areas directly above and below the lidar are blind spots. You can scan with the device facing any direction. If you are making large rotations, try to keep the movement slow and steady. Do not continuously move the scanner up and down to capture. Illustrated tilt is just one motion to change direction of LiDAR Field of View, not an example of necessary repetitive motion.
Page 63 How does LiDAR work?
Page 64 While its origins date back to robotics papers SLAM published in 1986, SLAM technology has only recently advanced due to improved processing power Simultaneous and 3D sensing hardware. Localization SLAM deals with the Mapping problem of a machine understanding its environment and its position and movement within that environment.

Page 75 Using your External Battery Some of our users use an external battery pack to increase scanning time. This is a beta for our pro user workflow. If you are interested in purchasing a Pro Kit, please contact support@paracosm.io. USING YOUR EXTERNAL BATTERY Make sure to plug in your external battery when your PX-80 is at full power before you start scanning.
