  • Publication number: 20150098622
    Abstract: An image processing method and system of an AVM system are provided. The method includes photographing, by a controller, an environment around a vehicle to generate a top view image and creating a difference count map by comparing two top view images photographed at time intervals. Partial regions in the created difference count map are extracted and an object recognizing image is generated by continuously connecting the extracted regions of the difference count map. Accurate positions and shapes of objects positioned around the vehicle may be recognized, and more accurate information regarding the objects around the vehicle may be provided to a driver.

  • Publication number: 20150063630
    Abstract: An apparatus and method for detecting an obstacle include a camera to photograph first and second images at different points in time successively. A calculator is configured to calculate a movement distance and a rotation amount of a vehicle by comparing the two images photographed by the camera with each other. A rotation amount compensator is configured to compensate for the rotation amount of the first image based on the second image. A difference value calculator is configured to calculate a difference value between the first image of which the rotation amount is compensated for and the second image based on the calculated movement distance of the vehicle. An obstacle detector extracts a region having the difference value exceeding an expectation value to detect the obstacle.

  • Publication number: 20150063647
    Abstract: An apparatus and a method for detecting an obstacle are provided. The apparatus includes a memory configured to store program instructions and a processor that is configured to execute the program instructions. The program instructions when executed are configured to compensate a position of a second image based on a first image based on a moving distance of a vehicle between the first image and the second image captured at different times and respectively generate a difference image based on a difference between the first image and the second image and between the first image and the second image in which the position is compensated. In addition, binarization is performed of the difference image and a synthetic image is generated for the two difference images. Then, the obstacle is detected by selecting a pixel corresponding to an area where the bit value is detected from the synthetic image.

  • Publication number: 20140355822
    Abstract: An apparatus and a method for tracing a parking-lot is provided that includes a controller configured to recognize at least one parking-lot from a previous image frame which photographed a surrounding of a vehicle and extract a template according to a type of a parking-lot line of the recognized parking-lot. In addition, the controller is configured to generate a template transformed based on a position information of the parking-lot and calculate similarity by comparing a template generated from a previous image frame with a parking-lot line recognized from a current image frame. A position of a parking-lot is determined according to the calculated similarity and the controller is configured to correct the template based on an information of a parking-lot line extracted from the determined position.
