Problems solved by technology
In general, the image analysis process includes two steps of detection and recognition. However, due to the deviation of the shooting angle, the shape of the image is distorted. The detection process only obtains the smallest circumscribed rectangular area of the distorted image, which cannot be recognized and can only be adjusted continuously. Shooting angles until a recognizable image is detected seriously affects the efficiency of image analysis

The invention provides an image detection method and device, electronic equipment and a storage medium, and relates to the field of image detection. According to the invention, the method comprises the steps: acquiring an original image, wherein the original image comprises a to-be-detected image, and the to-be-detected image is a polygon at least comprising four vertexes; then, inputting the original image into a feature extraction network of a pre-trained image detection model to obtain a feature map of the original image; inputting the feature map into a coordinate prediction network of an image detection model to obtain vertex coordinates of the to-be-detected image, and determining the to-be-detected image from the original images according to the vertex coordinates; and finally, according to the vertex coordinates, performing perspective transformation on the to-be-detected image to obtain a target image. According to the invention, the influence of image distortion caused by a shooting angle on image detection and recognition is eliminated, the shooting angle does not need to be adjusted for multiple times, and the efficiency of image detection is improved.
Description
technical field [0001] The present invention relates to the field of image detection, in particular to an image detection method, device, electronic equipment and storage medium. Background technique [0002] With the development of digital technology, image analysis is involved in many life scenarios, for example, in mobile payment, payment is completed by scanning a QR code. In general, the image analysis process includes two steps of detection and recognition. However, due to the deviation of the shooting angle, the shape of the image is distorted. The detection process only obtains the smallest circumscribed rectangular area of the distorted image, which cannot be recognized and can only be adjusted continuously. Shooting angles until a recognizable image is detected seriously affects the efficiency of image analysis. Contents of the invention [0003] Embodiments of the present invention provide an image detection method, device, electronic equipment, and storage m...
