Automatic attitude error correction laser range finder

Abstract

The invention discloses an automatic attitude error correction laser range finder. The automatic attitude error correction laser range finder comprises a housing, a laser module, a controller, a Bluetooth module, a display screen and a power supply module, wherein the laser module, the Bluetooth module, the display screen, the controller and the power supply module are arranged in the housing, andthe Bluetooth module, the display screen, the laser module and the power supply module are all connected to the controller. The automatic attitude error correction laser range finder is characterizedin that the laser module comprises a first laser module and a second laser module; and the first laser module and the second laser modules are disposed on two opposite sides of the housing respectively and are connected with the controller; a gyroscope is connected onto the controller; and the housing is provided with function buttons connected with the controller.

Description

technical field [0001] The invention relates to the field of measuring tools, in particular to a laser range finder for automatically correcting attitude errors. Background technique [0002] Existing laser range finders usually have a laser transmitter and receiver. By calculating the sending and receiving delay time, the length and dimension of the measured space or object can be obtained. Compared with the traditional ruler, the existing laser range finder has the advantages of fast speed, small size and light weight when measuring long dimensions. [0003] However, there are still many shortcomings in the actual use process: [0004] First, due to the attitude deviation of the measurer such as the hand-held tilt (mainly manifested as the laser beam of the hand-held tester not coincident with the straight line where the measured distance is located), the error of the measurement result is caused. [0005] Second, the measuring instrument needs to be placed at the begin...

Problems solved by technology

[0004] First, due to the attitude deviation of the measurer's hand-held tilt (mainly manifested as the non-coincidence of the laser beam of the hand-held tester and the straight line where the measured distance is located), the error of the measurement result is caused.

[0005] Second, the measuring instrument needs to be placed at the beginning of the measured distance for measurement. When the measured distance is very long, the measurer needs to move the device to one of the endpoints to start measurement, which is inconvenient to use; Measure the distance from the point to both ends and add the result, because there is no guarantee that the two measurement laser beams are on the same straight line, resulting in an increase in error

[0006] At present, there is also a bubble level installed on the measuring instrument on the market for the attitude correction reference of the measurer, but this method can only serve as a reference for horizontal or vertical measurement to reduce errors, and it is not applicable for non-horizontal or vertical measurement occasions , and the error cannot be quantified

And the function of the existing measuring instrument is also relatively single, it can only be used for distance measurement
