Be equipped with in the base 1 and be used for the drive platform 6 pivoted platform driving piece 9 through platform driving piece drive platform 6 is rotatory for the jewelry of treating the survey and drawing is rotatory.
In the present invention, the platform 6 can be directly mounted on the output shaft of the platform driving member, and the rotation of the platform 6 is realized by the rotation of the output shaft of the platform driving member. The upper surface of the platform 6 is a plane or forms an upward convex round table on the upper surface so as to be convenient for placing jewels. In order to enable the platform to rotate at a suitable rotational speed, e.g. at a constant speed, the platform drive preferably uses a stepper motor.
In order to facilitate the replacement of jewels needing information collection, the jewels are placed on the platform through the tray, the tray can be provided with fixing structures, such as clamping grooves and the like, which are adaptive to the shape of the jewels, and users can select different trays according to the shape of the jewels. The platform drive may rotate the tray 360 degrees to obtain 360 degree data of the jewelry.

In the invention, the light source 4 is a laser light source, the light source comprises four light source fixing columns 14 symmetrically arranged on the inner wall of the cylinder body, 4-20 light spots 15 are distributed on each light source fixing column, and the light spots can emit light rays and project on jewelry to be measured. Preferably, each light source fixing column is distributed with 10 light spots or more, the light source fixing columns with common sizes are 10 light spots, and the jewelry to be surveyed can also have mini-sized light source fixing columns according to different volumes, and the number of the light spots is less than 10; there may also be large-sized light source fixing posts, with 20 light spots, etc. Preferably, a plurality of light spots on the light source fixing column are arranged at different angles, so that light can be provided for jewelry on the platform from different angles, and comprehensiveness of surveying and mapping data is guaranteed.
The laser light source may be used to measure the overall shape and size of the jewelry, and the method of measuring jewelry with the laser light source may use optical triangulation to measure the entire curve of the jewelry by rotating the jewelry. Optical triangulation methods can be divided into direct and oblique. The direct type is that light beams emitted by a light source are vertically incident on the surface of a jewelry, the jewelry rotates to enable an incident light point to move along an incident optical axis, and scattered light from the incident light point is received by a receiving lens of a light collecting piece and is imaged on a sensitive surface of a photoelectric receiving element of the light collecting piece. The oblique type is that the light emitted by the light source is incident on the measured surface at a certain angle with the normal direction of the measured surface of the jewelry, and the other is the same as the direct type. Compared with the direct type, the oblique type can receive the positive reflected light from the measured jewelry and is more suitable for measuring the jewelry with the surface close to the mirror surface, while the direct type is suitable for measuring the surface with good scattering performance due to the characteristic of receiving the scattered light, otherwise, a measuring blind area exists due to the fact that most light rays are reflected; the oblique incident light spot irradiates different points of the jewelry, the displacement condition of a certain point of a measured object cannot be directly obtained, but the direct incident light spot can; the oblique-incidence type resolution ratio is higher than that of the direct-incidence type resolution ratio, but the measurement range is smaller, the light spot is larger, and the direct-incidence type light spot is small and the light intensity is concentrated. Therefore, direct-projection or oblique-projection light triangulation methods can be selected correspondingly according to the characteristics of jewelry to be measured aiming at the advantages and the disadvantages of direct-projection and oblique-projection respectively, so as to achieve better measuring effect. The laser light source may also be used to gather internal characteristics of jewelry.
