Method and device for determining opening angle of cabinet door, electronic equipment and readable storage medium

The invention is suitable for the technical field of images, and provides a method and device for determining the opening angle of a cabinet door, electronic equipment and a readable storage medium. The method comprises the following steps: acquiring a first image of a to-be-detected storage cabinet, wherein the first image is an image comprising a storage area in the to-be-detected storage cabinet; performing vertical line detection on the first image to obtain a vertical line in the first image; determining the ratio of the distance from the end point of the vertical line in the first image to the target frame in the first image to the length of the first image; according to the pre-established corresponding relation between the ratio and the cabinet door opening angle, the target opening angle corresponding to the ratio is determined, and the opening angle of the cabinet door of the storage cabinet can be accurately obtained through the ratio between the distance from the end point of the vertical line in
