Abstract
A distance sensor is disclosed composed of a pair of objective lenses 1 and 2 separated by a base length L, and a pair of two-dimensional image sensors 3 and 4. A left and a right image of a moving object 5, shifted from each other by a horizontal distance corresponding to a distance R to the object 5, is formed on the sensors 3 and 4. The left or the right image formed on the sensor is displayed on the display 11. A human operator initially sets, via the window forming device 12, the dimension and position of a window within the screen of the display. Thereafter, the microcomputer 10A samples at a predetermined sampling period the pixel signals of the image sensors 3 and 4, adjusts the dimension and the position of the window such that the window just covers the image of the object, and determines the amount of shift of the left and the right images on the basis of the image within the window.
