Abstract

The invention discloses an indoor laser range finder for facilitating the subway project cost and aims at providing an indoor laser range finder, thereby eliminating an error caused by measurement ofthe bracket. The indoor laser range finder comprises a support frame installed on a range finder body. The range finder body includes a housing, a first laser emitting device, a first photoelectric conversion device, a second laser emitting device, a second photoelectric conversion device, a control circuit board, and a power source. With setting of the first laser emitting device and the first photoelectric conversion device as well as the second laser emitting device and the second photoelectric conversion device, the accuracy of measuring of the measuring instrument is improved when the twogroups of devices cooperate with each other. With an air level and a compass, the accuracy of the measurement is improved further and the measuring precision is improved.

Description

technical field [0001] The invention relates to the technical field of indoor ranging, in particular to an indoor laser rangefinder for convenience of subway engineering cost. Background technique [0002] With the increasing rise of the construction industry, all kinds of measuring instruments have become dazzling, and the measurement methods are becoming simpler and faster, especially the supervision units and construction units need to check and accept the space height and width of various buildings. A convenient and quick measuring tool is essential . [0003] Laser range finder is an instrument that uses laser to accurately measure the distance of the target. When the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. The las...
