Calibration

Select the camera calibration method from the drop-down box.

[Grid Pattern Calibration]
Camera calibration is performed by using a calibration grid on which the predetermined pattern is drawn.
[Robot-Generated Grid Cal.]
The camera calibration is performed by moving a target mounted on the robot end of arm tooling along a grid, within the camera's field of view.
[Camera Calib. For 2-D Vis. Track]
Camera calibration dedicated to the visual tracking. Perform camera calibration by using a calibration grid in the wizard form.
[No Calibration]
When using this camera only for the inspection vision process and the 2D calibration-free vision process, camera calibration is not required. In such cases, select [No Calibration].

When selecting a calibration method, necessary steps are added in the navigation area in accordance with the selected method.

Camera Calibration
iRVision finds parts in an image snapped from a camera. In order to compensate the robot based on the positional information that iRVision found, the positional information needs to be converted from the camera coordinate system to a robot coordinate system (user frame or tool frame).
In order to perform such data conversion, data which describes where the camera is placed and where the camera is looking is required. The data is called \"camera calibration\". Calibrating cameras accurately is very important so that your robot can be compensated accurately.
