Description

Digital building measuring device based on three-dimensional scanning Technical Field The utility model relates to the technical field of building measurement, in particular to a digital building measurement device based on three-dimensional scanning. Background The three-dimensional laser scanning technology is also called as a live-action copying technology, and the three-dimensional coordinate data of the surface of the measured object can be rapidly acquired in a large area and high resolution by a high-speed laser scanning measurement method, so that a large amount of space point location information can be rapidly acquired, and a brand new technical means is provided for rapidly establishing a three-dimensional image model of an object. When the device in the prior art works, the height of the three-dimensional laser scanner cannot be adjusted, so that the measurement can be completed only by a plurality of times of measurement by a worker. The Chinese patent discloses a three-dimensional scanning digital building measuring device (grant bulletin number CN 221424422U), which is characterized in that the height of the whole supporting mechanism can be adjusted through the arrangement of an adjusting component, when the height of a scanning camera needs to be adjusted, the adjusting component can be started to drive the supporting frame to rotate along with a connecting rod, so that a supporting rod and the supporting frame are adjusted to a proper angle, at the moment, along with the rotation of the supporting frame, the height of the scanning camera also changes along with the rotation of the supporting frame, after the measuring work is finished, the adjusting component can be started again, the supporting frame is driven to rotate to one side of the supporting rod, so that the supporting mechanism is conveniently folded and stored, meanwhile, the height of the supporting mechanism is shorter, and the phenomenon that the scanning camera is broken due to the fact that a scanner shell is collided by external force can be avoided. The height adjustment is realized by virtue of the fact that a motor I in an adjusting assembly drives a bevel gear I and a bevel gear II to be meshed and driven, and then a connecting rod and a fixed rod are driven to rotate a supporting frame, so that the height adjustment mode is relatively troublesome, additional electric equipment is required to be started for operation, a transmission structure (bevel gear set) is complex, the on-site rapid maintenance or fault elimination is inconvenient, and the use complexity and the dependence on electric power supply are increased.
