Abstract

The embodiment of the invention discloses a vehicle detection method and device. The method in the embodiment of the present invention includes acquiring the image pyramid of the target image; sliding the detection window on the image pyramid according to the preset step size to obtain multiple detection blocks; using multiple pre-trained cascaded classifiers to determine the A detection block containing a vehicle in a plurality of detection blocks, and marking the detection block containing the vehicle as a vehicle candidate window, recording the confidence of each of the vehicle candidate windows; filtering the vehicle candidate window to determine the target vehicle window, outputting window information of the target vehicle. The embodiment of the present invention improves the accuracy of vehicle detection and also maintains a relatively fast detection speed.

Description

technical field [0001] The invention relates to the technical field of vehicle detection, in particular to a vehicle detection method and device. Background technique [0002] Computer vision is a science that studies how to make machines "see". To put it further, it refers to using cameras and computers instead of human eyes to identify, track and measure targets, and further processing graphics to make computers It is processed into an image that is more suitable for human observation or sent to the instrument for detection. As a scientific discipline, computer vision studies related theories and technologies, trying to build artificial intelligence systems that can obtain 'information' from images or multidimensional data. [0003] Due to its key role in the field of semi-automatic and automatic driving, automatic vehicle detection has been a hot research topic in the field of computer vision for many years. There are still many gaps in practical requirements. [0004]...
