Embodiment 1

[0026] figure 1 A structural block diagram of the object three-dimensional reconstruction device provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0027] The object three-dimensional reconstruction device includes: a first light capture module 102 , a second light capture module 103 , a light generation module 101 , a target 104 and a processing module 105 . Wherein, in the direction of the light emitted by the light generating module 101, the target 104 is a double-layer or multi-layer closed ring structure, and is arranged between the light generating module 101 and the target object. The light generating module 101 is configured to generate a source light so that the source light passes through the target 104 to project toward the target object and reflect to the first light capturing module 102 . The second light capture module 103 is configured to capture the second light reflected by the target object. The processing module 1...

Abstract

The invention is suitable for the technical field of three-dimensional reconstruction, and provides a three-dimensional reconstruction method and device for objects. The device comprises a first light capture module, a second light capture module, a light generation module, a target and a processing module; in the direction of light emitted by the light generation module, the target is a double-layer or multi-layer closed ring-shaped structure, and is arranged between the light generation module and a target object; the light generation module is used for generating a source light to ensure that the source light is emitted to the target object through the target and then reflected to the first light capture module; the second light capture module is used for capturing a second light reflected by the target object; the processing module is used for carrying out three-dimensional reconstruction on the target object according to a first light captured by the first light capture module and the second light captured by the second light capture module. The device is capable of strengthening the ability of resisting the interference of external environmental disturbances; and the measurement precision is not influenced by the small-amplitude movement of the target of the light generation module due to the external vibration, so that the measurement precision is relatively high.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional reconstruction, in particular to a method and device for three-dimensional reconstruction of an object. Background technique [0002] In modern industry, traditional measuring equipment, such as three-coordinate measuring machine, caliper, micrometer, etc., can no longer meet the needs of the development of modern manufacturing technology due to slow measurement speed and low efficiency. And the computer vision detection technology has been more and more widely used in industrial production because of its non-contact, fast, high precision, high degree of automation and many other advantages. Computer vision detection methods include methods based on a single camera combined with structured light, binocular vision methods, and projectors with cameras. At present, the methods used to collect point cloud data on the surface of physical objects can be basically divided into two categories: ...
