Embodiment Construction
[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] The purpose of the present invention is to protect a self-rotating structural apparent three-dimensional scanning device, including a support frame 2, a walking assembly, a functional box body 3, a hollow disc 6, an adjustable connecting rod, and multiple imaging units, see figure 1 .
[0035] The support frame 2 is provided with a base plate, and the support frame 2 may be a circular structure during specific implementation.
[0036] The walking assembly is arranged on the support frame 2, and the walking assembly includes a plurality of support rods 10 connected to the support frame 2. The end of the support rods 10 is provided with a traveling wheel set 1, and the traveling wheel set includes at least 2 steering wheels and 2 driving wheels. The support rod 10 can be stretched and adjusted in length according to the on-site detecti...

The invention relates to a self-rotation type structure appearance three-dimensional scanning device which comprises a supporting frame, a walking assembly, a functional box body, a hollow disc, an adjustable connecting rod and a plurality of imaging units, a circle of transmission teeth are arranged on the inner edge of the hollow disc, the transmission teeth are meshed with a motor gear, and a plurality of sliding clamping pieces are arranged on the outer edge of the hollow disc. The sliding clamping piece is clamped on the outer edge of the functional box body in a sliding manner and can rotate relative to the functional box body under the transmission type driving of the motor gear; the multiple imaging units are distributed on the adjustable connecting rod at different angles and postures, and the multiple imaging units collect multiple view angle images of a specific point position through rotation of the hollow disc so as to be used for establishing an overall 3D point cloud model within a scanning range. Compared with the prior art, through the annular meshing transmission structure, an accurate rotation adjustment program is achieved, the multiple imaging units collect multiple view angle images of a specific point position, and finally an overall 3D point cloud model in a scanning range is established.
Description
technical field [0001] The invention relates to a structure apparent three-dimensional scanning device, in particular to a self-rotating structure apparent three-dimensional scanning device. Background technique [0002] The scale of my country's infrastructure construction is very large, but as the use time of infrastructure continues to increase, its structural diseases are also increasing. If the disease cannot be discovered in time and corresponding measures are taken to restrain the further development of the disease, it will pose a great threat to the safety of the infrastructure. Therefore, the management and maintenance of infrastructure is of great significance, especially for large infrastructure structures such as roads, bridges, and dams. [0003] One of the core tasks in the management and maintenance of large infrastructure structures is the detection of diseases and assessment of the technical condition of the different structural components. The detection p...
