Abstract
The present invention relates to ranging system and ranging method, the ranging system includes: a ranging apparatus and a terminal device (3), wherein the ranging apparatus includes: a measuring wheel (1), a rotating shaft disposed on the measuring wheel (1), and an electronic counter (2) connected to the rotating shaft and used to obtain distance information of the measuring wheel; wherein the ranging apparatus or the terminal device (3) further includes an angle sensor; communication module being arranged on the terminal device (3) and the ranging apparatus, respectively; the terminal device (3) including data processing module configured to generate a traveling trajectory diagram of the measuring wheel, in real time, based on the distance information from the electronic counter (2) and the angle information from the angle sensor. Thereby, a traveling trajectory diagram can also be generated in real time on the basis that a ranging function is achieved, such that working efficiency is effectively improved. A function of marking lines according to a predesigned diagram in a construction site can also be achieved by cooperating with a marker (4), and the present invention has a si…
