    This paper proposes a 3D space distance measuring method to accomplish non-contact 3D space distance measuring by using a digital camera or digital video camera. The measuring principle of the proposed method in this paper is to learn the present camera shooting distance and the horizontal or vertical distance between the given points according to the number of pixels of the image in horizontal motion corresponding to the moving digital video camera or digital camera. The measuring structure proposed in this paper does not employ image graphic recognition or image signal analysis method to accomplish distance measuring, therefore, high-speed micro-computer and Digital Signal Processor are not used. All the distance measuring data come from a single horizontal scanning line. Only by modifying the system software of the digital video cameras (digital cameras), all makes of digital video cameras or digital cameras can have the feature of measuring 3D space distance.
