The invention discloses a laser three-dimensional measurement device, which comprises two double-rotation joints, a laser emitter, a collector and a processor. The double-rotation joint comprise a first rotation joint and a second rotation joint. One of the first rotation joints rotates theta c2, the second rotation joint rotates theta a2, and the laser emitter is driven to rotate and then is aligned with a point to be measured. The other one drives the collector to rotate for shooting, so that the to-be-measured point forms a laser spot on the collector. The sum of the rotating angle of the first rotation joint and the angle of the laser spot deviating from the center in the horizontal direction in the collector is theta c1, and the sum of the rotating angle of the second rotation joint and the angle of the laser spot deviating from the center in the vertical direction in the collector is theta a1. and the processor calculates three-dimensional coordinates of the point to be measuredaccording to the theta c2, the theta a2, the theta c1 and the theta a1. And the laser emitter and the collector are separately arranged, so that the measurement of a three-dimensional space in a largeviewing angle range is realized. The three-dimensional coordinates of the to-be-measured point are obtained through the rotation parameters, convenience and rapidness are achieved, the number of affected factors is smaller, and the measurement flexibility is higher.
Description
technical field [0001] The invention belongs to the field of laser three-dimensional measurement, and more specifically relates to a laser three-dimensional measurement device and a measurement method. Background technique [0002] Laser three-dimensional measurement technology can perform automatic measurement without touching the measured object, so as to obtain the required data and information, and perform certain processing to generate a real three-dimensional model. [0003] Laser 3D measurement devices are widely used in measurement work, and can be applied to reverse 3D parts to obtain the precise size and shape of parts; they can be combined with navigation and positioning technologies to obtain large-area digital model information, establish 3D models of urban buildings, obtain Geographic location information; it can be used to monitor the small deformation of large objects such as bridges, buildings, and mountains, and to predict various disasters. Therefore, the...
