Problems solved by technology

Method 1: In the modeling process, semantic classification can be realized according to deep semantic features to obtain semantic information very well, but spatial location information can be lost; Method 2: Spatial location information can be obtained according to shallow features, which can lead to a large The amount of calculations requires high computing resources
In general, with these two methods, not only the classification accuracy is not high, but also the amount of calculation is very large. For this, there is no effective solution in the related art

Abstract

The invention relates to a target detection method and device, electronic equipment and a storage medium. The method comprises the following steps: carrying out the feature extraction of an image, andobtaining the image features of different levels; performing spatial position information processing on the image features of different levels according to the grids of different granularities to obtain a processing result; obtaining features with different scales and different semantics according to the image features of the different hierarchies and the processing result; and performing targetdetection according to the features of different scales and different semantics to obtain a detection result. By adopting the method, the classification precision can be improved and the calculated amount can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision processing, and in particular to an object detection method and device, electronic equipment, and a storage medium. Background technique [0002] In an object detection scenario of computer vision processing, in order to achieve object detection, modeling is required. Method 1: In the modeling process, semantic classification can be realized according to deep semantic features to obtain semantic information very well, but spatial location information can be lost; Method 2: Spatial location information can be obtained according to shallow features, which can lead to a large The amount of calculations requires high computing resources. In general, using these two methods, not only the classification accuracy is not high, but also the calculation load is large, and there is no effective solution in the related art. Contents of the invention [0003] The present disclosure propose...
