TDA4VM: Information about SDE precision on depth estimation

Hi, 

For details of SDK module performance .Please check the TRM SDE chapter(https://www.ti.com.cn/cn/lit/zip/spruil1)

Also, SDK have a demo , you can refer to the link(https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_04_00_06/exports/docs/vision_apps/docs/user_guide/group_apps_basic_demos_app_stereo.html) to test the demo. Thanks.

Thanks for you reply.

But for the first link, it's a PDF document and we had viewed it. There are few description about the DMPAC SDE performance.

The second link is for the SDE demo,  we have already run the demo. But we still can't find the detailed depth estimation performance about the SDE module.

Could you guys give some more detailed information?

Thanks very much.

Renf, 

We are check if there are any detailed information that we can share with you. 

If you can run this demo , I suggest that you can run this demo for your testing. 

After your running this demo, please check if there are anything that don't match with your requirement.

We are testing the SDE depth estimation performance. But we can't get much precise results about the SDE because we don't know the detailed implementation about the SDE module. And we don't know how to adjust the SDE params for better performance.

So can you TI guys give some detailed depth estimation performance reports about the TDA4 SDE module?

Thanks very much

Renf, 

The max disparity search range of SDE is 191 (0 ~ 191). Its actual detection range will depend on focal length and baseline distance.

For KITTI 2012 and KITTI 2015 data set, 3-pixel error of SDE is around 7.3% ~ 7.8%.
