摘要： A method for detecting a front vehicle comprises: a moving light detecting step of detecting a front moving light area of an own vehicle in at least one image of a front scene of the own vehicle obtained at a time; a vehicle candidate generating step of extracting a light area pair from the detected front moving light area so that a front vehicle candidate is generated; and a vehicle candidate verifying step of verifying that the front vehicle candidate is the front vehicle in cases where the front vehicle candidate meets predetermined characteristics of a vehicle light.

摘要： Disclosed are a method and a device for detecting traffic signs in an input image camera. The method comprises a color space converting step of converting the input image into a HSV color space image; a filtering step of filtering, based on a predetermined pass range of a standard color of each of the traffic signs, the HSV color space image to obtain a filtered image, and then generating one or more connected domains based on one or more regions in the filtered image; a removing step of removing, based on a standard rule of the corresponding traffic sign, at least one of the generated connected domains, not being the corresponding traffic sign, and letting others of the generated connected domains be candidate traffic sign domains; and a recognition step of recognizing, based on a feature of each of the candidate traffic sign domains, the corresponding traffic sign.

摘要： Disclosed are a scene video switch system and a scene video switch method. The system comprises an input unit configured to input an image currently captured by a video capture unit to serve as a current image; a detection unit configured to detect all of interesting elements and latent elements in the current image so as to determine a maximum possible existing area of the interesting elements; a state switch unit configured to carry out, by using a predetermined finite state machine, switching between scene states of the maximum possible existing area according to predetermined different scene states and switching conditions; and a display unit configured to extract, based on a current scene state switched by the state switch unit, an area of concern coinciding with the current scene state from the maximum possible existing area to serve as a scene video for display.
