Abstract

A detection method, storage medium and electronic device. The detection method includes: acquiring an image to be detected obtained by photographing a first classroom by a first imaging device; acquiring a reference image; acquiring a feature point set of the image to be detected and a feature point set of the reference image, wherein the feature point set of the image to be detected includes at least one The first feature point, the feature point set of the reference image includes at least one second feature point; the first feature point pair set is obtained; the second feature point pair set is obtained; according to whether it is based on the first feature point pair set and the second feature point pair The set acquires at least one cross-matched feature point pair, and determines whether at least part of the teaching information display area of ​​the first classroom is located outside the imaging area of ​​the first imaging device. The at least one cross-matching feature point pair includes a first feature point pair and a second feature point pair that satisfy the cross-matching condition. The detection method can automatically detect whether at least part of the teaching information display area is located outside the imaging area.
