Abstract:
본 발명은 다채널 영상 정합 시스템 및 그 방법에 관한 것으로서, 보다 상세하게는 차량의 전·후방, 좌·우측의 영상의 영상을 YUV 422 형식을 그대로 유지하면서, 영상의 사이즈를 1/2가량 리사이즈하고, 리사이즈된 각 영상을 하나의 영상으로 정합 한 후, 탑뷰 영상으로 변환하기 때문에, 메모리를 많이 절감할 수 있고, 이로 인하여 탑뷰 영상의 프레임 저하가 전혀 없는 장점이 있는 다채널 영상 정합 시스템 및 그 방법에 관한 것이다.

Abstract:
An apparatus and a method for generating a panorama image and an apparatus for monitoring a rear view of a vehicle based on a panorama image are provided to generate panorama monitoring images in real time about images obtained from cameras, thereby enabling a driver to efficiently monitor a rear view in real time. The first image and the second image are obtained(S200). An overlapping area in which the first image and the second image are overlapped is obtained based on directivity of a pixel about the obtained first and second images(S210). The first and second images are combined based on the obtained overlapped area to generate a panorama image(S220). The generated panorama image is displayed(S240).
Abstract:
PURPOSE: A multi-channel image registration system and a method thereof are provided to resize the size of the image into 1/4 size while maintaining the image of the front, rear and right/left sides of the vehicle in a YUV 422 format. CONSTITUTION: An image resizing unit(110) deletes the luminance information within each pixel in a photographed image while jumping over the luminance information one by one. The image resizing unit deletes all color difference image within each pixel while jumping over a pixel one by one. The image resizing unit realigns the luminance information and the color image repeatedly in each pixel. An image matching unit(120) integrated the resized images into one image.
Abstract:
A reward guiding method is provided to display moving orbit quickly without complicated calculation imposing load within a vehicle. An automatic OSD(On Screen Display) line generating method for parking assist system comprises a step of inputting information of a vehicle; a step of inputting information on a camera installed to a vehicle; a step of calculating coordinate of moving orbit of a vehicle mating to steering angle according to rotation of a steering wheel; and a step of string data on coordinate calculated to mate to the steering angle and the steering angle. A moving orbit is displayed by coordinate data corresponding to the steering wheel of a vehicle on the displayer.
Abstract:
PURPOSE: A system and a method for controlling the camera operation for a vehicle are provided to prevent consumption of unnecessary electric power by minimizing a flickering of a display unit due to the ON/OFF repetition of the camera. CONSTITUTION: A system for controlling the camera operation for a vehicle comprises a plurality of cameras(10), an operating switch(20), a speed perception sensor(30) and a control unit(40). A plurality of cameras is installed on the back or front optional location of the vehicle. The camera outputs a photographing signal after photographing backward and forward of the vehicle in response to a photographing control signal. The operating switch outputs a camera operation starting signal by a driver. The speed perception sensor senses the present speed of the vehicle. The control unit controls the cameras one the camera operation starting signal is input from the operating switch. The control unit receives a current speed value of the vehicle from the speed perception sensor and compares to a first critical value. The control unit outputs a photographing control signal to the camera, if the first critical value is smaller than the current speed value.
