AR card punching method and system based on OpenCV and storage medium

The invention discloses an AR clock-in method based on OpenCV. The AR clock-in method comprises the following steps: starting an AR camera of mobile equipment to capture an actual scene; analyzing a scene image captured by the AR camera by using OpenCV, and detecting whether a real object exists or not; if the real object is detected, creating AR experience in the AR scene, and preparing a 3D model and clock-in information; creating an AR anchor point in the AR scene according to the real object position detected by OpenCV to represent the real object position; loading the 3D model, and placing the 3D model on the position of the real object according to the position of the AR anchor point; acquiring current clock-in information and adding the current clock-in information to a specific position of the 3D model; and displaying the 3D model containing the clock-in information in the AR scene. According to the invention, the accuracy of clock-in recording is improved, and the clock-in recording is not interfered
