Embodiment Construction

[0029] Attached below figure 1 A method for generating a 360-degree panoramic bird's-eye view for assisting vehicle driving disclosed in the present invention is further described in detail:

[0030] Step 1: Set up wide-angle cameras around the vehicle: the front camera can be set up under the vehicle logo; the rear camera can be set up under the rear cover of the vehicle; the left and right cameras can be set up under the left and right rearview mirrors. There must be an overlapping area between two adjacent cameras, and it is guaranteed to cover all the field of view around the vehicle without visual blind spots. The camera installation location and shooting area are attached figure 2 shown, where C 1 :C 4 is the installation position of the camera; W 1 :W 4 Capture overlapping areas for two adjacent cameras.

[0031] Step 2: Mark two points in the overlapping area of ​​two adjacent cameras in step 1, and use the line connecting the two points to determine the initial...

Abstract

A 360 degree panoramic aerial view generation method used for assisting vehicle driving is disclosed. The method is characterized by: firstly, erecting four wide-angled cameras around a vehicle and guaranteeing that the cameras can cover all the field areas surrounding the vehicle; secondly, calibrating a camera parameter and carrying out distortion rectification on the collected image; then, carrying out areal perspective transformation on the rectified image so as to obtain the aerial view with a downward view effect; finally, establishing a image splicing lookup table so that a system can rapidly complete splicing of a panoramic picture through a lookup table method. The method is simple is easy to perform. A hardware equipment requirement is low. The system realizes the splicing of four pictures through the lookup table mode, which is rapid and has less amount of calculation. The operation parameter which is calibrated once by using the method can be served as a constant, be stored and be used in real time hardware system work so that system processing time can be substantially reduced and the real-time performance requirement of the system can be satisfied.

Description

technical field [0001] The invention belongs to the fields of vehicle assisted driving, digital image processing and machine vision, and in particular relates to a method for generating a 360-degree panoramic bird's-eye view for assisted vehicle driving. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, automobiles have become an important part and main means of transportation in people's lives. In the process of driving a car, the driver observes the surrounding environment by turning the head and the rearview mirror, but the visual range is limited, and there are many visual blind spots, and traffic accidents or vehicle scratches may occur if you don’t pay attention. Therefore, how to expand the driver's field of vision and eliminate blind spots has become an important solution to effectively reduce accidents, and it is also a research hotspot in the field of automotive assisted dri...
