opencv2/tracking/tracking_legacy.hpp compile error with sdk

[astel_]

Hello

Yocto OS : nanbield-6.6.3-1.0.0
Opencv : 4.8.1.imx

I tried to use tracking algorithm using opencv tracking_legacy.hpp.
But when I tried to compile it using sdk that I built, it seems i encounter some issue. the error log is at the attachment file.

Is this a bug in this opencv-imx in this version? and do anyone have solution for this

Thank you

Hi

You need update your code, the apis have changed for opencv 4.8.x, please refer documents.

Thank you for your reply.

apparently i use wrong implementation regarding how to use legacy tracker of opencv.

there is a sample file from opencv-contrib that tell us how to use that correctly:
