Abstract

The invention provides a space distance measurement method based on an intelligent cell phone. The space distance measurement method is realized by three steps of indirect distance data acquisition, data processing and mathematical calculation. The space distance measurement method has the advantages that (1) indirect measurement is carried out step by step by using a laser distance measurement module to obtain parameters needed by space distance measurement, so as to prevent the problem of like products that the cost of equipment is increased by adopting a plurality of laser distance measurement modules to measure distances; (2) a innovative single-arm fixed shoulder positioning method is used for realizing two-times distance measurement so as to avoid causing influences that a distance measurement starting point has displacement; meanwhile, complicated operation of similar methods in which a fixed bracke is rotated to obtain an angle change is avoided so that the space distance measurement is simple and convenient.

Description

technical field [0001] The invention relates to a space ranging method, in particular to a smart phone-based space ranging method. Background technique [0002] Laser ranging uses lasers as light sources to measure distances. According to the way the laser works, it can be divided into continuous lasers and pulsed lasers. Gas lasers such as helium-neon, krypton-cadmium, and argon ions work in a continuous output state and are used for phase laser ranging; double heterogeneous gallium arsenide semiconductor lasers are used for infrared ranging; solid-state lasers such as ruby ​​and neodymium glass are used for Pulsed laser ranging. Due to the advantages of high laser brightness, good directionality and monochromaticity, coupled with the semi-integrated and conductive electronic circuits, the laser rangefinder can work day and night and improve the distance measurement accuracy compared with the photoelectric rangefinder. , significantly reducing power consumption and weight...
