Abstract

The invention relates to a method and device for detecting an occluded object, which belongs to the technical field of image processing and solves the problem that existing methods cannot detect whether occlusion occurs between objects of different shapes and sizes and cannot distinguish mutually occluded objects from other objects. The method includes: obtaining the training image and the image to be recognized in the dense scene and preprocessing the training image and the image to be recognized; marking the category and position coordinates of the target to be recognized in the preprocessed training image; establishing an improved neural network Model and use the marked training images to train the improved neural network model to obtain the detection model. The improved neural network model includes the CBAM attention module to enhance the feature extraction ability of the detection model to be recognized; Occluded objects are detected to obtain detection results. This method can improve the detection accuracy and positioning accuracy of occluded objects to meet the accuracy requirements of the algorithm in industrial applications.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for detecting occluded objects. Background technique [0002] With the vigorous development of deep learning in recent years, object detection technology has also been greatly developed. Various object detection algorithms are relatively mature, but there is still a lot of room for optimization in target detection in special scenes. Here we mainly study object detection in dense scenes. Since objects in dense scenes are not in an ideal detection environment, objects of different shapes and sizes may be occluded from time to time, which often results in inaccurate object detection. In some scenes, it is required to accurately detect a single object, which puts forward stricter requirements for the detection model. It is necessary to detect whether occlusion occurs between objects of different shapes and sizes, and to distinguish mutually occlu...
