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. Then, the pure component of translation speed is converted to a component of translation viewed from the ranging starting point to be accumulated to derive a navigation locus in a three-dimensional space to recognize the moving-object's own position. Thus, it is possible to analyze the surrounding environment in a three-dimensional space to cause the analyzed surrounding environment to be reflected on a navigation information, so that it is possible to obtain a precise and minute navigation information.
