Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] Referring to the accompanying drawings, a three-dimensional scanner includes a camera 12, a jig 5 for clamping a part 4 to be tested, a first drive motor 14 for driving the jig to rotate, and several irons that are on the same level and are spaced parallel to each other. quality probe 9, a probe installation platform 13 for installing each probe, a probe horizontal driving device for driving each probe to move horizontally and making each probe approach or away from the part to be measured, and a probe for driving the probe Install the probe up and down driving device that moves up and down on the platform. The far end of each probe 9 is provided with a red ball head. The camera 12 is used to take pictures of the red marks of each probe and input the picture data into the computer. The computer analyzes and recognizes it with a program. The horizontal ...

Abstract

The invention discloses a three-dimensional scanner and a three-dimensional scanning method. The three-dimensional scanner comprises a camera, a clamp for clamping a measured part, a first driving motor for driving the clamp to rotate, a plurality of probes which are located on the same horizontal plane and are distributed in parallel at intervals, a probe mounting platform for mounting the probes, a probe horizontal driving device for driving the probes to horizontally move and enabling the probes to be close to or far away from the measured part, and a probe vertical driving device for driving the probe mounting platform to vertically move. Each probe is provided with a color mark; the camera is used for shooting pictures of the color marks of the probes; the point cloud collection is adopted by the scanner, and is in a scanning linear shape; reverse engineering is facilitated. Meanwhile, a traditional laser or position sensor is not adopted, limitation of the scanning depth of the field does not exist, scanning of the large field depth and a large-size object can be completed, and in addition, the three-dimensional scanner is easy to manufacture, low in cost, free of consuming materials, and easy to operate and has the wide market prospects.

Description

technical field [0001] The invention relates to a three-dimensional scanner and a three-dimensional scanning method. [0002] Background technique [0003] The three-dimensional scanner is used to obtain the three-dimensional coordinates of the surface of the measured part, and the computer is used to analyze the three-dimensional coordinates of the measured part, and the parts are manufactured inversely. Three-dimensional scanners are mainly divided into contact three-dimensional scanners and non-contact three-dimensional scanners. Among them, non-contact three-dimensional scanners are divided into raster three-dimensional scanners (also called photographic three-dimensional scanners) and laser scanners. Three-dimensional scanners have white light scanning or blue light scanning, etc., and laser scanners are different from laser, line laser and surface laser. From the perspective of the development of 3D scanners, the first type of 3D scanner uses point measurement, repre...
