Real-time density maps generation of moving objects using embedded systems

The paper presents a realization of the determination of the so-called heat maps to represent the activity of moving people or other objects in a vision sequence. Image acquisition is performed with a fixed camera, and the generation of maps is performed using a low-cost embedded system. The prepared software based on the OpenCV library. Experimental benchmark studies were performed on Raspberry Pi and NVIDIA Jetson Nano minicomputers. It is shown that such minicomputers allow for a real time calculation of density maps.
