Description

technical field [0001] The invention relates to a laser projection point coordinate measuring device and a measuring method thereof, belonging to the technical field of laser projection point coordinate measurement. Background technique [0002] With the development of science and technology and the continuous improvement of technology, automation and intelligence of equipment in intelligent mines, military shooting training, and shooting competitions have become an inevitable trend. Laser targets are widely used as modern measuring equipment. In the application of intelligent mines, the accuracy of traditional laser targets is not high, and they cannot adapt to the harsh coal mining environment underground. They are easily disturbed by the harsh external environment, unstable and imprecise. With the continuous advancement and development of my country's major basic equipment industry, in the fields of large-scale equipment docking, shield guidance, ship equipment and guidan...

Problems solved by technology

[0003] At present, pose measurement is faced with problems such as large measurement space, high precision requirements, and complex shape of the measured object. A single pose measurement method is difficult to meet the measurement requirements. The combined measurement method based on the combination of multiple measurement methods has gradually been applied; laser target pose Measurement is a combined measurement method that uses laser targets to cooperate with measuring instruments such as total stations or laser trackers to complete measurements in the entire space

At present, various types of laser targets have been developed at home and abroad. Among them, the foreign laser target guidance systems mainly include the ZED system in the United Kingdom and the VMT system in Germany. The laser targets used are mainly composed of laser CCD cameras, dual-axis inclination angle However, the currently used laser target measurement system uses a large distance between photodiodes in the laser target, low sensing accuracy, and cannot sense and receive multiple laser signals at the same time, and the laser target used is a fixed size. Difficult to install and use, high production cost
