Description

technical field [0001] The invention relates to the technical field of optical three-dimensional scanning, in particular to a portable optical three-dimensional scanning device calibration device and a method for using the same. Background technique [0002] Optical three-dimensional scanning technology is a technology that uses optical measurement technology and optical information processing technology to obtain the three-dimensional shape and appearance data (such as color, reflectivity, etc.) of real objects in a non-contact manner. It has been widely used in many fields such as industrial automation, reverse engineering, object recognition, cultural relic protection, quality control, medicine and virtual reality. Optical 3D scanning equipment generally has both model building and measurement functions. It is a new type of measuring instrument. Therefore, it is very necessary to correctly and effectively calibrate its measurement accuracy to ensure reliable equipment per...

Problems solved by technology

The multi-dimensional mechanical turntable calibration device controls the different angles and orientations of the calibration bat through the multi-dimensional mechanical turntable to calibrate the optical three-dimensional scanning equipment. The disadvantage of this kind of calibration device is that it is not portable, it is not conducive to on-site calibration work, and the mechanism is complicated , many moving parts, poor device stability

The ball frame calibration device is a tetrahedron, hexahedron, or octahedron frame structure with calibration balls. Although the structure of this calibration device is relatively simple, each ball frame structure can only provide one or two fixed Calibrated distance size parameters, not adjustable, and expensive
