Maintenance

To keep picking accuracy from deteriorating over time, run infield verification periodically, and re-run hand-eye or robot calibration if verification or picking performance shows a problem.

Infield Correction

We advise running infield verification once or twice annually as a preventive measure. It is also good to monitor for picking accuracy or mispicks to check if picking performance deteriorates. Then, on such behavior, verify the camera for dimension trueness and correct for it if necessary. To read more about Infield correction, go to our Infield Correction page. Infield correction might require repeating the hand-eye calibration; see below.

Hand-Eye Calibration

If the picking accuracy starts to deteriorate, re-running hand-eye calibration might be necessary, in addition to infield verification and correction. For more details on hand-eye calibration, go to Hand-Eye Calibration page.

On-Arm Mounting

팁

Permanently mounting a Zivid calibration board (7x8 30mm, 300x300mm) in the scene allows for verifying camera dimension trueness as an automatic procedure, and without stopping the production. The same holds for performing hand-eye calibration; it can be done automatically, and without any mechanical changes to the cell.

Stationary Mounting

팁

로봇 플랜지와 그리퍼 사이에 ArUco markers 를 영구적으로 설치하면 핸드-아이 캘리브레이션 프로세스를 완전히 자동화할 수 있습니다. 생산 중단 없이 핸드-아이 캘리브레이션을 실행할 수 있다는 장점이 있습니다.

In addition, it is beneficial to have a system that allows quick mounting and dismounting of the Zivid calibration board (7x8 30mm, 300x300mm) on and from the robot. This allows one to perform infield verification and correction processes in addition to the hand-eye calibration process.

Robot Calibration

현장 검증이 양호한 결과를 보였고, 사전 생산 준비 단계와 동일한 방식으로 핸드-아이 캘리브레이션을 수행했다고 가정해 보겠습니다. 핸드-아이 캘리브레이션 잔차가 나쁘게 나오거나 잔차는 양호하지만 로봇 위치 정확도가 좋지 않다면, 로봇에 문제가 있을 수 있습니다. 이 경우 로봇 공급업체에 문의하여 로봇 운동학 보정 및 로봇 마스터링/제로잉 수행에 관한 추가 정보를 얻으실 것을 권장합니다.

Firmware Update

Each Zivid SDK version is matched with a specific camera firmware version. Whenever you upgrade the SDK, you must also update the camera firmware so that the two stay compatible.
