Screen Cropping

Screen Cropping#

Crop the scale dial area to reduce interference with recognition.

First, Retrieve camera images and then crop based on the camera image resolution.
Assume the image resolution is (640,480).
The method to calculate the top-left corner coordinates is as follows:
x = 80 / 640
y = 60 / 480
(x, y) = (0.125, 0.125)
Use this interface, inputting four coordinates to perform Screen cropping.
