Plotting Centroid with CUDA

nishanthrajkumar1 · February 5, 2024, 10:51pm

Hello,
I am trying a custom object detection and it is successfully working. However beyond drawing the overlay bbox, I tried to find the centre of the box and plot it as a circle so that I get a centroid right in the middle of the object. I tried to make changes to the source code (detectNet.cpp) from Jetson Inference C directory. Please let me know the problem to proceed further with my project.

Hi,

You can find the overlay of detectNet.cpp below:

github.com

dusty-nv/jetson-inference/blob/master/c/detectNet.cpp#L1000


      
          		}

          	}

          

          	// make sure there are actually detections

          	if( numDetections <= 0 )

          	{

          		PROFILER_END(PROFILER_VISUALIZE);

          		return true;

          	}

          

          	// bounding box overlay

          	if( flags & OVERLAY_BOX )

          	{

          		if( CUDA_FAILED(cudaDetectionOverlay(input, output, width, height, format, detections, numDetections, mClassColors)) )

          			return false;

          	}

          	

          	// bounding box lines

          	if( flags & OVERLAY_LINES )

          	{

          		for( uint32_t n=0; n < numDetections; n++ )

Thanks.
