Embodiment Construction

[0026] Based on the main design idea of ​​the present invention, the system of the present invention includes: hardware devices such as an online processing host, an offline processing host, and a camera, and an image acquisition module running on the online processing host, an online processing module, and an offline processing module running on the offline processing host. Modules Three software modules.

[0027] The rapid positioning and accurate detection process of the vehicle is as follows: the image acquisition module collects real-time image data of the vehicle monitoring area through the camera for analysis by the online processing module; the online processing module quickly detects the images collected by the image acquisition module, and locates the Vehicle objects, and provide the detection results to the offline processing module; the offline processing module performs more accurate analysis and detection on the detection results of the online processing module, a...

Abstract

The invention provides a vehicle identification system and a vehicle identification method based on three-dimensional model and image matching. The method comprises the following steps of performing initial detection location to an appointed object in a real-time video by the online algorithm, and performing more accurate analysis and detection to the detection result by the offline algorithm. According to the invention, the three-dimensional model of the vehicle is converted to be a two-dimensional image with object structure information at a specific visual angle and then is subjected to matching detection with the image to be detected provided by the online algorithm; meanwhile, for the successful matching result, the structure information can be provided; by adoption of the vehicle identification method, the high accuracy of the online vehicle detection result; in addition, the disadvantages that the offline vehicle detection method is complex and can not be used in a real-time system are overcome; and the purpose of obtaining real-time accurate detection results can be achieved by combining the online and offline detection methods to form complementary of algorithms.

Description

technical field [0001] The invention relates to the technical field of vehicle recognition systems, in particular to a vehicle recognition system based on three-dimensional model and image matching and a method thereof. Background technique [0002] At the Council on Foreign Relations held in New York in early November 2008, IBM President Palmisano delivered a keynote speech on "Smart Earth: Agenda for Next Generation Leaders", and "Smart Earth" and "Smart City" have gradually become current international focus. "Smart city" is an intelligent digital city management application with interventional and interactive functions in the development of digital cities. Its core content is based on the activation of data to establish a city dynamic data center. Life is managed in a dynamic, real-time, and more precise manner, resource utilization and labor productivity can be greatly improved, energy consumption and pollution discharge rates can be significantly reduced, resources an...
