Abstract
A ranging system includes a ranging apparatus, an angle sensor disposed in the terminal device or in the ranging apparatus, and a processor. The ranging apparatus includes a measuring wheel, a rotating shaft disposed on the measuring wheel, and an electronic counter connected to the rotating shaft and configured to obtain distance information, in real time, of a route which the measuring wheel has already traveled. The angle sensor is configured to obtain angle information in real time. The processor is configured to generate a traveling trajectory diagram of the measuring wheel based on the distance information from the electronic counter and the angle information from the angle sensor, and perform optimization processing on the traveling trajectory to generate an optimized trajectory diagram.
