Abstract

The invention provides a signal lamp identifying method in a video image. The signal lamp identifying method in the video image comprises a plurality of feature points in the video image are matched with a plurality of beforehand recorded feature points, wherein the plurality of feature points in the video image are detected and the plurality of beforehand recorded feature points are extracted from a signal lamp formwork image. The center positions of the signal lamp in the video image is confirmed according to cluster center positions of the feature points in the video image and distances between a cluster center position of the signal lamp formwork image and a center position of the signal lamp formwork image after successful matching. Color components of the signal lamp in the video image are identified and colors of the signal lamp of the video image are confirmed. The identifying signal lamp method of the video image can effectively identify the signal lamp in the video image and an expressive signal of the signal lamp in the video image. An identifying type though signal lamp physics wiring in the prior art can be avoided. The colors of the signal lamp is efficiently identified without the construction of spot signal lamps.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a method for recognizing signal lights in video images. Background technique [0002] With the development of social economy and the increase of vehicles, the development of intelligent transportation is also getting faster and faster. In illegal driving, red light detection is one of them. [0003] At present, the current way of detecting signal lamps is mainly to connect the signal lamps by connecting wires to identify the signal lamps. This method requires complex structure and difficult construction. Contents of the invention [0004] The invention proposes a method for identifying signal lights in video images. In order to solve the above-mentioned problem of difficult construction in the process of identifying signal lights. [0005] In order to achieve the above object, the technical solution of the present invention is achieved in that: [0006] Matching a pluralit...
