Abstract

The invention provides concave 3D information acquisition and measurement equipment based on an optical fiber bundle. The concave 3D information acquisition and measurement equipment comprises a housing, a plurality of optical structures, and a light guide structure, wherein the plurality of optical structures are distributed on a concave region of the housing; the plurality of optical structuresare optically connected with one ends of the plurality of light guide structures respectively; and the plurality of light guide structures are arranged in the housing. The invention proposes for the first time that multi-angle acquisition is realized by means of a plurality of light guides for the first time, so that the requirement of small space is met, and the special requirement of 3D acquisition can further be met; and by arranging the optical structures at the head portions of the light guides, the 3D acquisition quality is optimized, and the synthesis speed and the synthesis precision are improved.

Description

technical field

[0001] The invention relates to the technical field of shape measurement, in particular to the technical field of 3D shape measurement. Background technique

[0002] When performing 3D measurement, 3D information needs to be collected first. The currently commonly used methods include using machine vision to collect pictures of objects from different angles, and matching and splicing these pictures to form a 3D model. When collecting pictures from different angles, multiple cameras can be set at different angles of the object to be tested, and pictures can also be collected from different angles by rotating a single or multiple cameras. But no matter which of these two methods has a large volume, it is difficult to use them in occasions with small spaces, such as various small pipeline cavities. This is due to the impossibility of fitting a huge camera into the lumen of the pipe, and having to turn or move to take pictures.

[0003] In particular, there ar...
