Abstract

The invention relates to the technical field of image processing, in particular to an automatic identification method and device for a vehicle, and electronic equipment. The automatic identification method for the vehicle comprises the following steps that: preprocessing the frame image of a road video to obtain each frame of grey-scale map of a region of interest; processing each frame of grey-scale map of the region of interest to obtain a reconstruction skeleton drawing; adopting various morphology operators to process the reconstruction skeleton drawing to obtain a required connected domain drawing; and identifying a connected domain of which the morphological characteristics meet a first preset condition in the required connected domain as the vehicle. By use of the automatic identification method and device for the vehicle, and the electronic equipment, a data size can be reduced drastically, a great quantity of uncorrelated or weakly correlated information can be removed, the important structure attribute of each frame of gray-scale map is kept, interference factors, including road markings, motorcycles, bicycles, pedestrians and the like which are not vehicles, can be removed, and the problem that identification can not be carried out or an identification effect is poor since an available background image can not be obtained in a traffic jam road section can be solved.
