Connect the Power/LAN cable to the sensor and the other end to the Power and Ethernet ports on the Master 100 Using Gocator Scanner on Linux Running a Standalone system Y position increases as the object moves forward increasing encoder position. In surface data, the Y-axis represents the relative position of the part in the direction of travel. The origin is at the center of the measurement range and field-of-view (FOV). The X axis represents the sensor's FOV with +x pointing to the right (it's a left-handed system). The Z-axis represents the sensor's measurement range with the values increasing towards the sensor. The sensors are calibrated in engineering units (mm) and are ready to deliver profiles right out of box but alignment procedures are required to account for sensor mounting inaccuracies.īefore alignment, individual sensors use the coordinate system below. Alignmnet is performed in the Alignment panel on the Scan page of the web UI. Each range contains a height and a position in the sensor's field of view. Measures the height of an object from the laser triangulation and reports a series of ranges along the laser line, with each range representing the distance from the sensor's origin plane (z is in the range of 0 to 700mm or -350mm to 350mm). This is obtained as the sensor is moved across a surface. Z-linearity is the difference between actual distance to the target and the measured distance to the target, throughout the measurement range.ĭefault Z-Resolution from profile map is 0.0088 millimeters. It is best to position an object at no more than 35mm from an object in the z-direction The Z resolution is also closer at the close range and worse at the far range just as the X-resolution. ![]() Z Resolution is the variability in height measurement. X-Resolution is the horizontal distance between each measurement point along the laser line.ĭefault XResolution: 0.275mm. ![]() Due to the triangulation angle, the laser line appears in different positions on the camera depending on the 3D shape of the target. The sensor projects a laser line to the target and the sensor's camera views the laser from an angle capturing the reflection of the light off the target. The sensor captures a single 3D profile for each camera exposure.
