I am working on a project and we plan to integrate a camera to our robot cell. We use the UR5 and would like to use the camera as a feedback sensor. The accuracy requirement is +/- 0.5mm.

I would like to know what camera options are there and which ones are supported in ROS.

I have gathered from here that the accuracy of the kinect is +/- 1mm which can be improved by intrinsic and/or extrinsic calibration. Would that be suitable for my case?

I am new to image processing in ROS so kindly excuse me if I am missing anything.

the error shown is around 5 mm for one Kinect and that only in the case your object is 75 cm away from the Kinect. 0.5 mm is quite an idealistic expectation. If you want to do calibration, put OpenCV markers in your environment then you will get 0.1mm pose accuracy with a well calibrated camera.

So should I go for calibration with OpenCV markers with kinect or should I search for Industrial cameras?
