Kria™ KV260 Vision AI Starter Kit Defect Detection Tutorial
Known Issues and Limitations
Please first review the FAQ for commonly encountered issues across Kria SOM applications.
Defect Detection algorithm is evolving and will be updated in further releases. The present algorithm has the following limitations:
Only the MIPI interface camera is supported in this design.
Sensors other than AR0144 are not supported in this design.
This design has been validated only with 1280x800 resolution.
This design supports only GRAY8 (Y8) format.
System is not intelligent enough to identify whether the input is a mango. Therefore, pass only mangoes as input.
Input to system must only be one mango at a time.
The mango background should be black.
The known issues with the Defect Detection application are as follows:
For some mangoes, defects at the corner of the mangoes are not detected by the current defect detection algorithm.
Contours may be detected at the edges of the mangoes.
While running the application, user can see below error message which can be ignored.
/opt/xilinx/kv260-defect-detect/bin/ar0144-sensor-calib.sh: 38: Syntax error: "(" unexpected
On some monitors user may see below error during modetest, it can be ignored:
ubuntu@kria:~$ modetest -M xlnx -D B0010000.v_mix -s 52@40:3840x2160@NV16 setting mode 3840x2160-30.00Hz on connectors 52, crtc 40 failed to set gamma: Function not implemented
