Thank you Alex!
According to your reply, Should I use the gpu for large tasks such as Neural Network or large image instead of the task that need to process each frames?

RE: Question for GPU Usage
Thank you for reply Chad!
I already can run the example without docker.
My question is why GPU is slower than CPU in the result of image.
I am using opencv-opencl for my application. But I also got the result that GPU takes much time than CPU -
Question for GPU Usage
Hello, I am trying to use the GPU(Adreno 650) in VOXL2.
In the voxl-docker-opencv-opencl gitlab, It says this is the expected ouput.root@0a4f66eee0a6:/opt/workspace/examples/fast_corners# ./fast-corners FAST ( 300 x 168), keypoints: 557, time:0.487192 cpu [ WARN:0] Using world accessible cache directory. This may be not secure: /var/tmp/ FAST ( 300 x 168), keypoints: 557, time:6.319238 gpu
And it says GPU is too much slower than CPU. And I also got slower result compare to CPU.
Is it expected output? And What kinds of situations GPU is faster than CPU?
Thank you for your any advices! -
RE: VOXL2 Opencv with Opencl
The result of hellocl :
OpenCL error: clGetDeviceIDs(-1)
The result of fast_corners :
Enable OpenCL failed!
I built the opencv again with this file. I could install it but still same error. Is it caused by diff of GPU model?(Adreno 530 vs Adreno 650)

RE: VOXL1 PX4 connection issue
+) I think the flight core doesn't work anymore. There isn't any action when I connect this with QGC, MP with USB. And the part of flight core in the voxl1 is too high to touch it. Is it HW issue??

VOXL1 PX4 connection issue
Today, I wasn't able to connect VOXL1 & QGC. First screenshot is from VOXL1:voxl-vision-px4. But I think It should shows like second screenshot. How can I connect my VOXL1 with the QGC again?
Thanks
