ROS Melodic GPU compilation error #92

Open jainRAV opened 3 years ago

jainRAV commented 3 years ago

While compiling on Ubuntu 18.04 and ROS melodic with opencv 3.4.1, pcl_people_detector shows error:

#error GPU-based classifier has not yet been ported to OpenCV3/4.

Also opencv is installed with CUDA enabled. Does anyone know how to solve this issue?

Thanks

If you don't need maximum real-time frame rates, you can use the CPU-based version of that detector.

The GPU-based version needs to be largely re-written, since the relevant OpenCV API changed completely from version 2 to 3. We currently do not have plans to do so (due to lack of capacity), but appreciate any contributions by the community.

Alternatively, depending on which sensor you use, the upper-body detector might be an alternative. Both achieve roughly the same detection accuracy with the Asus Xtion Pro Live sensors.

@jainRAV did you find a solution?
