Angle-adjustable laser ranging device and laser ranging method

The invention relates to the technical field of distance measurement, aims at solving the problems that most of existing laser ranging devices are inconvenient to accurately guarantee that the measuring surfaces of the laser ranging devices are parallel to a plane needing to be measured, and measurement is inconvenient under some conditions, and provides an angle-adjustable laser ranging device and laser ranging method. The angle-adjustable laser ranging device comprises a rotating module, a laser ranging module and a control system, the laser ranging module is fixedly connected with the rotating part of the rotating module, and the laser ranging module and the rotating module are both electrically connected with the control system. The control system can receive and process the distance value measured by the laser ranging module, and controls the rotating module to drive the laser ranging module to rotate according to the distance value. The laser ranging device has the beneficial effects that the ranging re
