The invention relates to a distance determination method and a distance determination system. The distance determination method comprises the following steps: emitting a vertical laser beam rotating in a vertical plane at a first rotating speed by using a first laser emission part of a laser emission device; computing a time difference between a time when the vertical laser beam passes through a first optical detection component and a time when the vertical laser beam passes through a second optical detection component by using the first optical detection component and the second optical detection component which are at least partially located on the same vertical plane on a laser receiving device, wherein the distance between the two optical detection components is a first space; computing a first distance between the laser emission device and the laser receiving device according to the first rotating speed, the first space and the time difference. By using the method disclosed by the invention, the horizontal setting of the first optical detection component and the second optical detection component arranged on the laser receiving device can be guaranteed, and the distance between the specific positions of the vertical laser beams on the first optical detection component and the second optical detection component can be ensured as the first space, thereby ensuring that the measured or the computed first distance is accurate.
Description
technical field [0001] The invention relates to the field of distance measurement and positioning, and more specifically relates to a distance measurement method and a distance measurement system. Background technique [0002] In the prior art, the patent publication CN101206113A discloses a range finder and its distance measuring method. According to the range finder disclosed in this patent, a light beam with a certain predetermined rotational speed is provided by a rotating light source, and then the receiver is used to Detect the time difference when the light beam rotates from the first position of the receiver to the second position, and calculate the distance between the receiver and the rotating light source based on the detected time difference and the distance between the first position and the second position of the receiver . The distance measuring instrument and distance measuring method described above can conveniently realize the function of distance measurem...
