Abstract

Embodiments of the present invention provide a detection method and device, the method comprising: performing normalization processing on pre-stored sample frames, and mapping the normalized sample frames to multiple sub-regions of a specified quadrant region; Obtaining the salient feature model of the target object based on the salient features of the sample frame in each of the sub-regions; training a classifier according to the pre-stored sample values ​​and the salient feature model; preprocessing the acquired frames to be detected ; Using the salient feature model to perform feature extraction in the preprocessed frame to be detected, and using a trained classifier to detect whether the frame to be detected contains a target object. The detection scheme provided by the present invention uses the sample frame training to obtain the salient feature model and classifier of the target object to perform feature extraction and target matching on the frame to be detected, thereby increasing the detection rate while speeding up the detection speed.

Description

technical field [0001] The present invention relates to the technical field of video analysis and processing, in particular to a detection method and device. Background technique [0002] Pedestrians and non-motor vehicles are an important part of road traffic. At present, there are various detection methods for pedestrians, mainly using HOG features combined with pattern recognition detection methods to detect pedestrian targets, using background modeling and background difference to obtain preliminary positioning to reduce detection. scope. However, some existing methods have high complexity or problems of accuracy and robustness. Moreover, there are not many in-depth studies on the detection methods of non-motor vehicles at present, so how to detect non-motor vehicles accurately, quickly and with strong interference adaptability is a technical problem to be solved urgently in this field. Contents of the invention [0003] In view of this, the purpose of the present in...
