A fast scanning detection method

Abstract

The present application relates to a fast scanning detection method, which is used for a rotating scanning detection device that requires two or more detection samplings for the calculation of each scanning detection distance value, wherein each detection sampling includes: an emission light source emits an infrared Detection light; infrared detection light propagates in space, and is reflected when it encounters the measured object; the photoelectric sensor in the receiving device receives the infrared detection light reflected by the measured object; the rotating scanning detection device is at each detection angle position, only one probe sample is taken. A fast scanning detection method involved in this application, since only one detection sampling is required at each detection angle of the rotary scanning detection device, the time for the rotary scanning detection device to stay at each detection angle is reduced, and the rotation scanning The detection device rotates continuously and rapidly, so as to realize the detection of continuous rapid rotation scanning.

Description

technical field [0001] The present application relates to the field of optical ranging, in particular, to a fast scanning detection method. Background technique [0002] The optical rotary scanning detection device is a device that uses collimated beams to perform non-contact scanning detection through triangulation, time of flight (Time of Flight, referred to as TOF) and other methods. At present, a common time-of-flight optical rotary scanning detection device includes: a light emitting module, an optical lens, a chip for receiving and processing signals, a motor, a bearing and a conductive slip ring. The light emitting module emits a detection beam. The optical lens is located on the optical path of the light emitting module. The collimated light beam is emitted to the surface of the object to be measured. After encountering an obstacle, the light beam is reflected to the receiving chip, and the receiving chip transmits it to the receiving point through measurement. The ...
