Three-dimensional scanner fixing support for three-dimensional image acquisition of large product
Technical Field
The invention relates to the technical field of three-dimensional scanner accessories, in particular to a three-dimensional scanner fixing support for three-dimensional image acquisition of a large product.
Background
A three-dimensional scanner is a scientific instrument used to detect and analyze the shape (geometric structure) and appearance data (such as color, surface albedo, etc.) of an object or environment in the real world. The collected data is often used to perform three-dimensional reconstruction calculations to create a digital model of the actual object in the virtual world. These models have a wide range of applications, for example industrial design, flaw detection, reverse engineering, robot guidance, topographical measurements, medical information, biological information, criminal identification, digital cultural relic collections, film production, game creation materials, and the like. The purpose of a three-dimensional scanner is to create a point cloud of the geometric surface of an object, which points can be interpolated to the surface shape of the object, the denser the point cloud can create a more accurate model (this process is called three-dimensional reconstruction). If the scanner is able to acquire the surface color, a texture map, a so-called texture print, may be further applied to the reconstructed surface. Three-dimensional scanners can be analogized to cameras, and the sight range of the three-dimensional scanners is conical, and the information collection is limited within a certain range. The difference between the two is that the camera captures color information, while the three-dimensional scanner measures distance. Since the measured result contains depth information, it is often called depth video or distance video. Because the scanning range of the three-dimensional scanner is limited, it is often necessary to change the relative position between the scanner and the object or place the object on an electric turntable, and the object is pieced together through multiple scans. The technique of integrating multiple one-sided models is called video registration or alignment, which involves multiple three-dimensional alignment methods.
The existing three-dimensional scanner can be provided with a bracket with a rotary disc for surrounding scanning of small products, the scanning of large products is generally carried out by manually holding the three-dimensional scanner to survey and draw the products, the scanning position can be omitted in the manual handheld surveying and drawing process, partial characteristics of a three-dimensional model of the products are lost, and the height of the products is too high or too low, so that manual operation can have certain inconvenience.
