Distance measuring device and method

Abstract

The invention provides a distance measuring device and method, the distance measuring device comprises a laser distance measuring sensor, a projector and a controller, the laser distance measuring sensor is used for detecting the distance to a target position; the projector is used for projecting a target image to the target position, and the target image is used for representing the distance detected by the laser distance measuring sensor; the laser distance measuring sensor and the projector are both electrically connected with the controller, and the controller is used for controlling the projector to project light to the target position under the condition that detection of the laser distance measuring sensor fails. According to the distance measuring device, the projector is arranged to project light to the target position under the condition that the laser distance measuring sensor fails to detect, the light projected by the projector can serve as supplementary light of the laser distance measuring sensor, it can be guaranteed that the laser distance measuring sensor successfully detects the distance to the target position, and the detection success rate is increased; and the distance to the target position can be conveniently and intuitively checked.

Description

technical field [0001] The present invention relates to the technical field of ranging, and in particular, to a ranging device and method. Background technique [0002] With the continuous development of the mining industry, laser ranging sensors are more and more widely used in mines, and laser ranging has become an important means of non-contact measurement. However, due to the special environment of underground mines, the surface to be measured is irregular and easily affected by water mist, dust and other factors, resulting in low laser reflectivity, which leads to poor ranging effect. SUMMARY OF THE INVENTION [0003] The present invention provides a ranging device and method, which are used to solve the defect of poor laser ranging effect in the prior art in underground mines, and realize precise ranging of all parts of the underground mine. [0004] The present invention provides a distance measuring device, comprising: [0005] a laser ranging sensor, the laser r...
