Page 8: Use For Intended Purpose
1. Use for Intended Purpose The wenglor weQube is an optoelectronic sensor which is used for contactless inspection of specific objects. The sensor unites a camera unit, illumination, optics with auto-focus and an analysis module in a single hous- ing. The sensors work with a CMOS color or monochrome image sensor.

Page 82 The following settings/results appear – 1 to 3 points can appear depending on the Property previously selected construction method. Algorithm Selection for the construction method: Point 1 A fixed point is specified as point 1. Edge on Line An edge transition is looked for along a search line.
Page 83 Algorithm Selection for the construction method: Point 3 A fixed point is specified as point 3. Edge on Line An edge transition is looked for along a search line. The detected point is specified as point 3. Point (fixed or linked) A fixed point is specified as point 1. It’s also pos- sible to use a result point from another module as a coordinate point.
Page 84 Edge on Line Construction Method First of all, the search line’s gray-scale values are determined. Then a derivative is generated from the gray-scale values in order to ascertain where an edge is located. If several edges are found, polarity and the “find by” specification determine which edge will be used as a point for the coordinate system.
Page 85 By using First Score as a setting for Find by and using Dark to Bright as a setting for Edge Polarity, it can be assured that the first transition from dark to bright is used as a point for the coordinate system. The setting of Edge Width dictates how long a new brightness value has to be retained in order for the transition to be recognized as an edge.
Page 86 Find by This parameter can be used to specify which of the detected edges will be used on the search line. If several edge transitions are detected on Best Score the search line, the transition with the great- est contrast is selected. First Score If several edge transitions are detected on the search line, the first transition in the search...
Page 87 Edge on Arc Construction Method The construction method is the same as for “edge on line”. The difference is the search geometry.

Page 89 Threshold Threshold Gradient Neg specifies the negative gradient acceptance Gradient Neg threshold.

Page 154 Characteristic Contour Models Number of different models which should be detected. Up to 10 dif- ferent models can be taught in. Pyramid Steps With a value of 0, the algorithm automatically optimizes the number of model points. A value of 1 specifies that model points will be looked for in the original image, and thus this setting is the slowest.
Page 155 Characteristic Optimization In the case of especially large models, it may be advisable to select the number of model points by setting the optimization parameter to a value other than “-”. In the case of smaller models, reducing the number of points does not result in any acceleration. Auto The number of points is reduced automati- cally by the algorithm.
Page 156 Characteristic Contrast The contrast parameter specifies which gray-scale contrast the mod- el’s points must demonstrate. Contrast is a measure of local gray- scale differences between the object and the background, as well as between the parts of the object.

11.25. Module Statistics 11.25.1. Overview The application can be fine-tuned on the basis of statistical sensor data. Objective Prerequisites 1. Sensor is correctly connected (see section 5.5) 2. Connection has been established from the sensor to the software (see section 10.1.1) 3.
Page 183: Configuration
11.25.3. Configuration Under channel count, the statistic module includes the configuration, which depends on the number of chan- nels to be observed: • Channel #1 11.25.3.1. Channel # 1 Objective A certain value can be analyzed. The following settings/results are displayed: Property Minimum The lowest value of the most recently observed measured...
Page 184: Project Change Via Digital I/O
Ratio for Trend All observed measured value results are subdivided into older and newer results. The ratio of the number of older results to the number of newer results is indicated as the trend ratio. This ratio is set to 1 as a default value. Example of a trend ratio of 1.5 for 5 observed values Past Module State...
Page 185: Procedure
12.2. Procedure The sensor is switched to the project change mode by applying a voltage of greater than 7 V (high) to the previ- ously selected input pin for a duration of T_EN. Each positive edge is counted in the project change mode (one positive edge = project 1, two positive edges = project 2 etc.), until a voltage of less than 2 V (low) has been applied to the project change input for a dura- tion of T_DIS.

14.4. Device Settings Network and display settings, the sensor configuration and password changes can be entered under device settings. The following screenshot shows the default settings. 1. Network settings The IP address can be assigned automatically, or a specific IP address can be used. If a specific IP address is used, the following settings must be entered: IP address Enter the sensor’s IP address.
Page 190: Projects
2. Network Reset In the event of a network reset, the network settings are returned to their default values (see section 5.6). The network settings become effective after the sensor is restarted. The sensor settings remain unchanged. 3. Display Settings Refer to section 6.4.2 for a description of the display settings.

18. Appendix 18.1. Setting up an FTP Server at a PC Suitable software is required in order to set up an FTP server at a PC. Examples include: • FileZilla Server • Serv-U • CesarFTP A user must be created in the software, so that the FTP server knows who is permitted to access data. Note: Avoid simple, overgeneralized passwords in order to provide your FTP server with adequate security.

Page 195: Coordinate System
18.3. Coordinate system By use of coordinates, the position inside a coordinate system is defined uniquely (surface, volume etc.) The sensor operates in a predominantly two-dimensional image in which a point P (X, Y) is defined by the X and Y components.
Page 196: Image Sensor Coordinate System
18.3.2. Image sensor coordinate system The image sensor coordinate system represents the coordinates on the real CMOS chip area. • The coordinate origin is placed in the top left of the image sensor (the blue rectangle represents the light sensitive area of the image sensor) •...
