Title:
単眼ビデオカメラを使用した、車両からの目標点の距離および方向の算定
Document Type and Number:
Japanese Patent JP6726006
Kind Code:
B2
Abstract:
A method and system for determining a distance and direction between a video camera secured on a vehicle and a target point relies on an electronic control unit. The system maps and stores grid points representing a world coordinate grid onto a screen coordinate grid and displays the video image on a display using the screen coordinate grid. The system obtains a target point of an object in the video image and determines a locus of four closest grid points of the screen coordinate grid that encircle the target point. The system determines screen distances from the target point to each of the four grid points and maps the four grid points onto the world coordinate grid. The electronic control unit interpolates the location of the target point in the world coordinate grid as weighted by the screen distances. Using the video camera location in world coordinates and the target point location in world coordinates, the system determines a distance between the video camera and the target point.
