Example Embodiment

[0030] Specific embodiments of the present invention will be described in further detail below based on the drawings. It should be understood that the specific embodiments described here are merely examples and are not intended to limit the protection scope of the present invention.

[0031] Please refer to figure 1 The embodiment of the present invention provides a three-dimensional scanning system for acquiring or collecting three-dimensional point cloud data of the object 106 to be measured. The 3D scanning system includes a light source 101, a 3D module 102, a left camera 103, a right camera 104, and a data processing unit 105. The type of the three-dimensional scanning system is not limited. Preferably, the three-dimensional scanning system is a handheld multi-stripe binocular three-dimensional scanning system.

[0032] The mutual positions of the light source 101, the 3D module 102, the left camera 103, and the right camera 104 are not limited, as long as the measured object...

Abstract

The invention relates to a three-dimensional scanning system and a scanning method. The three-dimensional scanning system is used for acquiring the three-dimensional point cloud data of an object to be detected. The system comprises a light source, left and right cameras, a three-dimensional module group, a stripe matching module and a three-dimensional reconstruction module, wherein the light source is used for projecting a plurality of stripe patterns on the object to be detected; the left and right cameras are used for acquiring a 2D left image and a 2D right image of the object to be detected; the three-dimensional module group is used for collecting the depth map of the object to be detected; the stripe matching module is used for guiding left and right image stripes to match according to the depth map; the three-dimensional reconstruction module is used for searching the corresponding relation of a single point in a corresponding stripe center line segment through using the polarline geometric constraint relation of the left and right cameras in the matched and corresponding stripes of the left and right images, and then reconstructing the corresponding point into the three-dimensional point cloud data according to the calibration parameter of the three-dimensional scanning system. The invention provides the scanning method of a three-dimensional scanner.

Description

technical field [0001] The invention relates to a three-dimensional digital imaging sensor, a three-dimensional scanning system and a scanning method, in particular to a three-dimensional digital imaging sensor, a three-dimensional scanning system and a scanning method for a hand-held multi-stripe three-dimensional scanning system. Background technique [0002] 3D digital technology is an emerging interdisciplinary field of active research in the world in recent years, and has been widely used in many fields such as reverse engineering, cultural relic protection, industrial inspection and virtual reality. Hand-held portable 3D scanners are widely used in the field of 3D scanning due to their convenience and flexibility. The principle of existing handheld 3D scanners is mainly based on the active stereoscopic vision method of structured light. There are many modes of structured light, such as infrared laser speckle, DLP (Digital Light Processing) projected speckle, and simula...
