High-precision laser range finder and use method thereof

Abstract

The invention belongs to the technical field of surveying and mapping, and discloses a high-precision laser range finder and a use method thereof. According to the scheme, high-precision range finding can still be kept in a field environment. A range finder body can be adjusted before range finding by arranging a sensing column which deforms to a certain degree in a heating state, and shaping is carried out after adjustment to improve the positioning effect on the range finder body. Meanwhile, after being heated, an inner deviation ball in the sensing column is converted into an adsorption locking state from an original free movement state between the inner deviation ball and a point extension column, and then deviation sensing of the range finder body is achieved. Once deviation occurs, the inner deviation ball is inclined and a visual prompt is given. The deviation can be found and handled in time at the initial stage of the deviation, so that the phenomena of error accumulation and enlargement, even re-measurement and back-measurement are avoided, and high-precision of range finding is ensured.

Description

Technical field [0001] This application relates to the field of surveying and mapping, and Background technique [0002] The laser range finder is an instrument that utilizes a parameters of the modulation laser to measure the distance measurement of the target. The laser ranging instrument measurement ranges from 3.5 to 5,000 meters. [0003] According to the ranging method, the pulsed laser range finder is a pulsed laser beam to emit a bunch or a sequence short pulse laser beam to the target during operation, and receive the target reflection by the photoelectric element. Bunch, the timer measures the laser beam from the time transmitted to the received time, calculates the distance from the observer to the target. The phase method laser rangefinder is to detect the distance from the phase difference that detects the transmitted light and the reflected light in the space to propagate. The laser range finder is light, the size is small, and the operation is simple and accurate. ...

Problems solved by technology

[0004] When the laser rangefinder is used for surveying and mapping in the field, because it is directly exposed to the external environment, deviations are prone to occur during the ranging process, and sometimes it is difficult for technicians to find out in time, resulting in the accumulation of deviations and eventually resulting in low precision data that is difficult to use Even retesting and retesting occur
