[0062] The present invention will be further described below in conjunction with the drawings.
[0063] Reference Figure 1~Figure 8 , A multi-size shelf commodity inspection method, including the following steps:
[0064] (1) Obtain the shelf image to be tested;
[0065] (2) Preprocess the shelf image in step (1). Through edge detection, Hough transform and straight line filtering, the edge position of the shelf in the image is measured. Segment images with too many shelves, and rotate images with inclined shelves;
[0066] (3) Input the image obtained in step (2) into the feature extraction network to obtain 5 layers of feature maps with different depths;
[0067] (4) Perform feature fusion on the obtained feature maps of each layer;
[0068] (5) Perform regional nomination on the feature map through the regional nomination network to obtain the candidate frame;
[0069] (6) Use the target detection network to further correct the candidate frame and infer the type and precise coordin...
