Embodiment Construction

[0024] The present invention will be further described in detail with reference to the accompanying drawings.

[0025] from figure 1 It can be seen that the realization of the present invention is mainly participated by five functional modules: camera control module 1, motion detection vehicle capture module 2, license plate location module 3, green sign location module 4, and green sign recognition module 5. The first and second modules are implemented by our existing patented technology. For the technology, please refer to the "Comprehensive Control Technology of Camera Shutter and Gain Based on License Plate Brightness Contrast" and "Precise Recognition Method of High-speed Moving Vehicle Logo Based on Video" that we have applied for. "Two patents. The third license plate positioning module adopts the mature and widely used texture-based license plate positioning technology. The basic principle is that the camera control module performs linkage control on the camera-acqui...

Abstract

The invention relates to a method for identifying a green mark of the taxi, relating to the technical field of traffic control computer image process and mode identification, and comprising a camera control module, a movement detecting vehicle snapshot module, a number plate locating module, a green mark locating module and a green mark identifying module, wherein the camera control module is based on an intelligent vehicle information acquisition system. The location rule of the green mark locating module is based on color features and area features of a detecting region, and the color features are judged in an HSV (Hue, Saturation, Value) model space. The identification of the green mark identifying module comprises two stages: carrying out the morphology conversion according to an extracted selecting region of the green mark to obtain a more complete and regular processing region and calculating two circularity form factors of the region according to the fine process result of the first stage, integrating the result of the two circularity form factors to obtain the final identification according to the judgment rule, and outputting the identification result.

Description

technical field [0001] The invention relates to the technical field of computer image processing and pattern recognition, in particular to a taxi green mark recognition method for automatic detection of taxis by using image processing and pattern recognition technologies. Background technique [0002] In the process of urbanization in China, urban transportation is developing rapidly. As a beneficial supplement to the public transportation system, taxis play an important role in the travel of residents. At the same time, the management of taxis has also become increasingly prominent. For example, do not park according to the regulations, do not abide by the operating hours and location regulations, do not follow the instructions to get on and off passengers, etc. These violations not only bring chaos to transportation, but also have hidden dangers that endanger the lives and property of passengers at any time. Therefore, increasing the standardized management of taxis is a...
