Problems solved by technology

Its advantages are high precision, wide measurement range, and not affected by external light, but due to the need to contact the surface of the object, it may cause slight deformation and scratches to the measured object, the measurement speed is slow, the point cloud density is low, and the measurement process requires manual intervention
Non-contact 3D measurement uses the principle of optical triangulation. The measurement process does not require manual particip

Abstract

The invention provides a scanning device, an engineering vehicle and a scanning method. The scanning device comprises a sensor part, a total station, an inclinometer and a controller, wherein the sensor part is arranged on the engineering vehicle and comprises a laser and a camera, the laser can emit laser toward a calibration plate, and the camera can acquire the image information projected on the calibration plate by the laser; the total station is used to detect the position relationship between the calibration plate and the scanning device; the inclinometer is disposed on the scanning device for detecting the position relationship between the scanning device and the engineering vehicle; and the controller is connected with the sensor part, the total station and the inclinometer, the controller determines the position relationship between the camera and the scanning device according to the image information of the laser projected on the calibration plate and the detection result ofthe total station and further determines the position relationship between the camera and the engineering vehicle according to the position relationship between the camera and the scanning device andthe position relationship between the scanning device and the engineering vehicle. The scanning device provided in the invention is higher in scanning precision and low in making cost.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a scanning device, an engineering vehicle and a scanning method. Background technique [0002] Three-dimensional measurement technology is mainly used to reconstruct the three-dimensional characteristics of the surface of the measured object. According to the measurement form and means, it can be divided into contact and non-contact measurement. The classic application representative of the contact measurement system is the three-coordinate measuring machine. This measurement method requires the probe to be in contact with the surface of the measured object and move on the object, so as to obtain point cloud information relative to the coordinate system. Its advantages are high precision, wide measurement range, and is not affected by external light. However, due to the need to contact the surface of the object, it may cause slight deformation and scratches to the m...
