Abstract

The invention relates to the technical field of image processing, in particular to an object positioning method and device, electronic equipment and a storage medium, and aims to solve the problem that an object positioning method in the prior art is excessively limited. According to the embodiment of the invention, the method comprises the steps: obtaining an image which is collected by image collection equipment and contains a to-be-positioned target object, and determining the pixel coordinates of the target object in the image; and determining longitude and latitude coordinates of the target object according to the perspective transformation matrix corresponding to the image acquisition device and the pixel coordinates of the target object in the image. According to the embodiment of the invention, the longitude and latitude coordinates corresponding to the pixel coordinates of the target object in the image are determined through the perspective transformation matrix correspondingto the image acquisition device to complete the positioning of the target object, and the installation position of the image acquisition device is not strictly limited. Moreover, the perspective transformation matrix corresponding to the image acquisition equipment is determined according to pixel coordinates and latitude and longitude coordinates of a plurality of reference points, but selectionof the reference points is not strictly limited, so that the limitation is relatively low.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an object positioning method, device electronic equipment, and a storage medium. Background technique [0002] The location information of the vehicle plays a very important role in the driving process of the vehicle. For example, according to the vehicle location information, the distance between the vehicles can be accurately measured, and problems such as collisions between vehicles can be prevented to realize intelligent transportation; or according to The location information of the vehicle and the location information of the destination acquire the route to the destination, etc. With the development of science and technology, there are more and more methods to obtain the position information of vehicles by using image processing technology. [0003] At present, a realization process of using a single camera to locate a vehicle on the road is: obtain ...
