Abstract

The invention provides a 3D panorama image generating system and a method, wherein the system comprises an electronic control unit, a display unit and four cameras arranged at the front, the back, the left and the right of a vehicle. The method comprises the following steps: s11) calibrating the four cameras; s12) using the four cameras to acquire images; s13) establishing a three-dimensional curve-face model and performing triangular sectioning on the model; mapping the texture elements of the images and the position coordinates onto the three-dimensional curve-face model; and s14) outputting and displaying the 3D panorama images. According to the invention, through the four camera modules, the output of panorama images can be realized. The system is simple and can be mounted conveniently. The method is stable and easy to perform. With a fast running speed, the precision of the images is increased. The system and the method can be applied widely. With the system and the method, the computation amount can be reduced; and the costs of hardware and software can be reduced.

Description

technical field [0001] The invention relates to the field of advanced driving assistance systems for smart cars, in particular, to a system and method for generating 3D panoramic images on cars. Background technique [0002] In recent years, with the rapid development of the motor vehicle industry, traffic accidents are also increasing day by day, which makes people more and more concerned about the safety of cars, and the safety technology of cars has attracted more and more attention. Most of the traditional car panoramas are 2D panoramas, which simply stitch the collected images. Using 2D stitching technology will lose a lot of image data, and cannot make good use of the advantages of wide-angle lenses. For the driver, it is a generated panorama The image field of view is small, and the processing platform based on DSP is difficult to realize function expansion. [0003] The Advanced Driver Assistant System (ADAS) uses various sensors installed on the car to obtain envir...
