Problems solved by technology

[0005] For this reason, the first purpose of the present invention is to propose a method for object recognition, to form different regions of interest for different scanning depths, reduce the image range of object recognition, reduce the amount of calculation, improve the speed of object recognition, and solve the existing problems. There is only one large region of interest in the technology, which leads to a large amount of calculation in the recognition process and a long time-consuming technical problem for object recognition

Abstract

The invention provides an object recognition method and device, wherein, the method comprises the following steps: acquiring a region of interest formed for each scanning depth; wherein the size of the region of interest on the imaging plane is smaller as the scanning depth is deeper; collecting road condition images of the road ahead; a region-wide scan is performed in each region of interest toobtain a recognition result. By using the method, different regions of interest can be formed for different scanning depths, the image range of object recognition can be reduced, the computation amount can be reduced, the object recognition speed can be improved, and the technical problems of large computation amount and long object recognition time caused by only one large region of interest in the prior art can be solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an object recognition method and device. Background technique [0002] Object recognition, which is called Object Detection in English, is a technology for recognizing objects in images. When using the related object recognition technology to identify the object in the image, usually a region of interest (Region Of Interest, ROI) with the same size as the recognition frame is selected in the image, and the image in the ROI is scanned from the horizontal and vertical Matching objects are identified, and the ROI remains unchanged during the identification process. [0003] In order to ensure the accuracy of object recognition results, a larger region of interest is usually selected. When performing iterative calculations on the region of interest to identify objects in the image, the amount of calculation is very large, and object recognition takes a long time. E...
