Commonly used distance measurement methods include tape measure distance and photoelectric distance measurement. The measuring distance of a tape measure is measured along the ground using a tape-like ruler that can be rolled up, which is a direct measuring distance. Photoelectric ranging is to use an instrument to transmit and receive modulated light waves between two points, and measure the distance according to its propagation speed and time. It belongs to electronic physical ranging. Photoelectric ranging is indirect ranging.
