OpenCV4 daily practice day3: Run OpenCV sample program (object tracking)

step1: Prepare the camera, or use the computer's own camera. The Intel D435i is used here.

step2: Find the object tracking demo that comes with OpenCV- camshiftdemo.cpp , and add it to the VS2015 source file. Step3

: camshiftdemo.cpp's help file mentions that to run the program, you need to specify the camera number. (If not specified, the default camera number=0)

View—Property Manager—Double-click "Debug|x64"—Debug—Command Parameters—Enter camera number:0 (although the default is 0)

step4: Read camshiftdemo. The key description in cpp, such as pause, exit, etc.

step5: Run the program and the window screen seen by the camera will appear.

step6: track the selected area in the screen, and the running result (GIF animation)

evaluation: OpenCV4 official object tracking The algorithm effect is still possible.
