Problems solved by technology
[0003] In the existing three-dimensional laser scanning technology, it is necessary to manually move the object to be scanned or manually move the laser scanner to scan. When using a model that artificially moves the object to be scanned, if the object to be scanned is a fragile and variable object, the moving It is easy to cause damage or deformation of the object during the process, and it is easy to cause the object to be displaced during the artificial movement process. In the next scanning process, the received image will produce image deformation, which will also bring a lot of redundancy in the post-processing of the graphics. Work
In models that use artificial movement scanning, it is more likely to have disadvantages such as difficulty in image stitching and difficult control of scanning distance

The invention relates to a cross-shaped track object three-dimensional scanning molding device arranged in a box body.The device comprises a laser sensor unit, a transmission unit, a stepping motor unit and a control unit.The laser sensor unit comprises a sliding table and three laser sensors installed on the sliding table, and the laser sensor unit is used for scanning an object to be detected.The transmission unit comprises a supporting rod subunit and a transmission rod subunit.The transmission unit is used for supporting the laser sensor unit and driving the laser sensor unit to move.The stepping motor unit is installed on the upper portion of one side face of the box body and used for controlling rotation of the transmission rod unit so as to controlling movement of the laser sensor unit.The control unit is used for controlling operation of the stepping motor unit.Compared with the prior art, the device can carry out comprehensive three-dimensional screening on the object which cannot move or is easy to damage and unsuitable for being touched, is high in scanning precision by applying a cross-shaped track and is not likely to be disturbed.
Description
technical field [0001] The invention relates to the technical field of analysis and measurement control, in particular to a three-dimensional scanning and forming device for cross track objects. Background technique [0002] Three-dimensional laser scanning technology is a new technology developed in recent years, known as "another technological revolution in the field of surveying and mapping since GPS technology. As an effective means of obtaining spatial data, this technology is and other advantages are playing an increasingly important role in many fields such as industrial production, film and television production, fashion design, archaeological relics, geotechnical engineering, etc. With the innovation of science and technology, the development of new methods of work in various fields has been promoted. For example, traditional The archaeological industry is often carried out manually when excavating and recording, which is easy to cause damage to cultural relics. Usi...
