I was very confused while doing the project and realized that I needed help. First of all I have 2 images and one of these images contains highway with empty and the other one contains highway with cars on it. I am asked to find the number of vehicles in the second picture using OpenCv and these two images, but I don't know which paths to follow. More precisely, I don't know how to use the two images together.(Using Python)

CodePudding user response：

I would suggest

1. Reducing the frist picture from the second.

   1.1. Since they are the same (as far as I understand), you will get 0 values everywhere but the cars.

2. Use cv2.findContours on the result on step 1. to get the contour of each car,

3. Count the number of contours, should match the number of cars
