Embodiment Construction

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0042] see figure 1 , which is a block diagram of a system for real-time restoration of a three-dimensional real model of a vehicle provided by the present invention. As can be seen from the figure, the system 100 is mainly composed of a vehicle information collection device 101 , an image information registration module 102 , a vehicle 3D point cloud generation module 103 , a vehicle texture mapping module 104 and a 3D vehicle model display module 105 .

[0043] Wherein, the vehicle information collection device 101 establishes a mapping relationship between height and image coordinates by calibrating the collected data, and collects the height of passing vehicles and vehicle video information in real time.

Abstract

The invention relates to a system and method for recovering a three-dimensional true vehicle model in real time and belongs to the field of intelligent transportation. The system and method can be applied to vehicle information management and traffic cases involving vehicles. The system comprises a one-dimensional laser sensor and a monocular camera. The whole modeling process is divided into an off-line process and an on-line process. The off-line process comprises self-calibration of the camera and mutual calibration of a laser and the camera. The on-line process comprises the steps of collecting laser information and vehicle video information, synchronizing the information, fusing the information, generating three-dimensional model point clouds of the vehicle and conducting triangularization connection and texture mapping. Compared with a traditional three-dimensional vehicle modeling method, the method has the advantage that the three-dimensional vehicle model generated through the method has real-time performance and verisimilitude, but through the traditional three-dimensional vehicle modeling method, only a simple skeleton model of the vehicle is recovered, and abundant texture information is not involved.

Description

technical field [0001] The invention belongs to the technical fields of computer vision, computer graphics and automation, and specifically relates to a method for three-dimensional modeling of a vehicle and a device used in the method. Background technique [0002] Any object in the real world is three-dimensional, and it is of practical significance to restore the 3D model of the vehicle in the computer. In the field of intelligent transportation, more and more three-dimensional electronic maps have appeared in people's field of vision, so the models of three-dimensional vehicles can also be displayed to people more realistically in the map with its unique style. Secondly, the current traffic accidents are frequent It has been found that the use of 3D vehicle models can more realistically show the occurrence of traffic accidents to people, which facilitates the investigation and evidence collection of accidents. [0003] The traditional 3D modeling of vehicles is mainly t...
