Abstract

The invention provides a target detection method and system and a terminal device, wherein the method comprises the following steps of extracting a plurality of targets from a measured image by usinga detection frame by using a convolution neural network; acquiring feature attributes of the target, the feature attributes comprising spatial features and explicit features; according to the featureattributes, calculating the association features among the targets based on the relationship calculation model; integrating the feature attributes of the target by using the associated features to obtain aggregated features; substituting the aggregation feature into a backtracking relation sub-network composed of a full connection layer of the convolution neural network and the relation calculation model, and calculating a quasi-prediction score; calculating a classification score according to the quasi-prediction score and the detection frame; classifying and detecting a target according to that classification score. The invention greatly improves the efficiency and accuracy of target detection.

Description

technical field [0001] The invention belongs to the technical field of target detection, and in particular relates to a target detection method, system and terminal equipment. Background technique [0002] Target detection has important application value in many fields, such as intelligent deployment and control security, industrial information applications, and automobile assisted driving. However, various appearance features, complex and diverse background environments, dynamically changing scenes between pedestrians and cameras, and strict requirements for real-time performance and stability of the system pose great challenges to the target detection problem. The current target detection method based on deep learning has too many redundant calculations, and cannot accurately identify small and dense targets in the scene, and there are problems such as insufficient use of effective information in the scene. [0003] To sum up, there is a problem of low efficiency and accu...
