Problems solved by technology

The detection speed of target detection based on single-scale feature maps is fast but the accuracy is low. Compared with target detection based on single-scale feature maps, multi-scale feature maps include more features related to objects, and target detection based on multi-scale feature maps The accuracy is high, but the data volume of the multi-scale feature map is large, and the detection speed of the target detection is slow, so it is difficult to apply in some application scenarios that require high real-time performance

Abstract

The embodiment of the invention provides a target detection method and device. The method comprises the following steps: acquiring a to-be-detected image; performing feature extraction on the to-be-detected image to obtain a single-scale feature corresponding to the to-be-detected image; based on the single-scale feature corresponding to the to-be-detected image, performing hole convolution processing to obtain a multi-scale feature corresponding to the to-be-detected image; based on the multi-scale features corresponding to the to-be-detected image, predicting a detection result of the to-be-detected image, wherein the detection result comprises the type of an object in the to-be-detected image and / or the position of the object in the to-be-detected image. High-precision target detection is carried out at a high detection speed.

Description

technical field [0001] The present application relates to the field of neural networks, and specifically relates to a target detection method, device, electronic equipment and storage medium. Background technique [0002] Currently, detection networks are usually used for detection of objects, human bodies, etc. The detection speed of target detection based on single-scale feature maps is fast but the accuracy is low. Compared with target detection based on single-scale feature maps, multi-scale feature maps include more features related to objects, and target detection based on multi-scale feature maps The accuracy is high, but the data volume of the multi-scale feature map is large, and the detection speed of the target detection is slow, so it is difficult to apply it in some application scenarios that require high real-time performance. How to detect objects with higher accuracy at a faster detection speed has become a problem that needs to be solved. Contents of the ...
