摘要： An image processing method includes: acquiring an input image of a teaching scenario; performing detection on the input image to determine a rectangular detection area that includes a blackboard-writing area; analyzing the rectangular detection area to determine a target area corresponding to the blackboard-writing area; determining four vertices of the target area; and according to the four vertices of the target area, performing coordinate transformation on the target area to obtain a corrected blackboard-writing area image.
