  • Patent number: 6385334
    Abstract: In a correction operating part 10c, three regions including two distant regions and one near region are selected on a reference image picked up by a main camera 2, and distance data are added to the positions of the respective regions to define a range, in which corresponding regions exist, in a comparative image picked up by a sub-camera 3 to search the range to determine the positions of the regions at a resolution of one pixel or less. Then, on the basis of one of the distant regions, a translation correction value and an angle of rotation for the comparative image are derived from the relationship between the positions of the respective regions to be added to the set value of an affine transforming circuit 18 to parallel-displace and rotate the comparative image. Thereafter, an angle of rotation for causing the horizontal line of the main camera 2 to be parallel to the base line of a stereo camera is derived to be added to the set value of an affine transforming circuit 17 to rotate the reference image.

  • Patent number: 6148250
    Abstract: A three-dimensional image of a ground surface taken by a stereoscopic camera is converted to a distance image in a stereoscopic processing section. In an altitude calculating section, after peculiar points contained in the distance image are deleted and further the lens distortion is deleted from the distance image, the distance image is transferred to a real space coordinate. Then, an equation approximating to a plane is obtained from data of the distance image and a length of a perpendicular line to the plane is calculated as a ground altitude.

  • Patent number: 6025790
    Abstract: A camera assembly 10 images a distant landscape and a downward landscape every a predetermined period of time. A position recognizing unit 30 of a moving object (autonomous running vehicle) detects the movement of the moving object on the basis of the movement between the imaged pictures of the distant and downward landscapes, which are imaged at different imaging times. That is, the movements of the distant-view and down-view images are converted to the moving amounts in the actual space on the basis of the distance images thereof, respectively, and the component of rotational speed based on the movement of the distant-view image is removed from the component of velocity based on the movement of the down-view image to derive a pure component of translation speed.

  • Patent number: 5410346
    Abstract: A distance between a running vehicle and an object is determined over an imaged picture with high reliability. Three-dimensional objects or a road shape along with accurate position or dimension are also detected. An object within a set region outside a vehicle is imaged by a stereoscopic optical system to input the imaged picture of the object into a stereoscopic picture processing apparatus. The stereoscopic picture processing apparatus processes the picture imaged by the stereoscopic optical system to calculate a distance distribution over the entire picture. A road/three-dimensional object detecting apparatus calculates three-dimensional positions of respective portions of objects corresponding to information of the distance distribution to detect the shape of the road and a plurality of three-dimensional objects by using information of these three-dimensional positions securely and with high reliability.
