Vision process without calibration

    Hi guys !

    I'm currently working on a Pick&Place application for labels on electronic boards. My aim is to calibrate the point at which the robot picks up the label using vision. Unfortunately, the label dispensing system I'm using doesn't allow the installation of a calibration grid, and the inclination of the label following its pre-peel can vary.

    To overcome these constraints, I opted for a vision process without calibration. However, I encountered a problem with the IRvision FANUC Offset Data Calculation Tool. The following error message appears: CVIS-700 Circular target mark was not found.

    In IRvision > Offset Data Calculation Tool I get ‘status : In Process’ (see 2nd screenshot).

    I've tried several combinations: readjusting the working distance of the camera, changing the colour of the table to get a better background contrast with the label, but I'm still stuck.

    I don't understand why this tool is looking for targets to calibrate when the process is supposed to be carried out autonomously, without calibration. Could you help me solve this problem or give me some idea of how to get round it?

    Thank you in advance for your assistance :winking_face:



    You need to complete the learning-procedure (that's currently "in process").
    It's described pretty good in the manual: B-83919EN/08

    Reach out to your local FANUC rep to acquire this.

    Regarding the "Calibration free":ness of this vision process. It only refers to that the system doesn't require a normal camera calibration to work. However, some form of learning (which could be considered a sort of calibration..... semantics..) is required for the system to know where the found target is placed.
