Abstract

PURPOSE:To easily and accurately obtain the speed of a moving body by inputting the prescribed position of the moving body as a video signals and measuring the speed from the prescribed time quantity of the shifting of the moving body image on a CRT screen. CONSTITUTION:The prescribed position (e.g. the tip of rod steel whose length is measured) of the body which moves at a constant speed is detected by a position detector 2 which uses laser light, etc., and its signal is used as a trigger to input an image by an ITV camera 3. This signal is A/D-converted 4 and stored in a memory 5, and the image is displayed on a CRT 7 through a CPU 6. Then the image of the tip position of the rod steel 1 which is a constant time later is inputted similarly and stored in another memory base of the memory 5, and then it is processed and recognized similarly. At this time, when the position relation of the optical system including the camera 3 is constant and video signal scanning conditions are constant, the quantity and required time of shifting are recognized from the data in the memory 5 through image processing because the length of the rod steel is measured previously, thereby calculating the speed.
