Camera Installation

Select a camera installation for each calibration. Calibration methods vary (requirements for vision sequences, calibration procedure) depending on the camera installation methods. Note that the wrong setting may result in improper calibration.
Vision Guide 8.0 supports the following camera installations:

Camera Installation	Description
Mobile Camera (mounted on Joint #2)	Camera is mounted on Joint #2 on SCARA robot or Cartesian robot.
Mobile Camera (mounted on Joint #4)	Camera is mounted on Joint #4 on SCARA robot or Cartesian robot.
Mobile Camera (mounted on Joint #5)	Camera is mounted on Joint #5 on 6-Axis robot.
Mobile Camera (mounted on Joint #6)	Camera is mounted on Joint #6 on 6-Axis robot.
Fixed downward Camera	Camera and target objects do not move and are fixed in the work envelope of the robot. The vision system uses the camera to acquire position information in the robot coordinate system. If the camera is not installed vertically to the XY plane of the specified coordinate system, correction of lens distortion and camera tilt must be performed. Specified coordinate systems are robot base and local coordinate systems.
Fixed upward Camera	Camera does not move and is looking up into a portion of the robot work envelope. For example, this installation method is used to check the position of the object which is carried by the robot. The calibration target is on the end effector or the object held by the robot.
Standalone Camera	Camera can be installed anywhere. Camera does not have a relation with the robot. With this method, position information in the Robot coordinate system cannot be acquired. However, it can be converted from the image coordinate system to the camera coordinate system. That is, simple length measurement can be performed.

Tips:
Correction of lens distortion and camera tilt can be configured for all camera installation.
