Abstract

The invention provides a three-dimensional acquisition device capable of horizontally moving, which comprises a horizontal rail and an acquisition frame, wherein the acquisition frame is movably connected with the horizontal rail; the acquisition frame comprises a stand column and a cross beam, and an image acquisition device is arranged on the acquisition frame; and the image acquisition device is connected with the acquisition frame. In the invention, a gantry support structure is adopted for the first time, so that three-dimensional information of a large object can be collected. The gantrysupport can be disassembled and expanded, can adapt to objects with different sizes, and is convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of object measurement, in particular to the technical field of using images to perform 3D acquisition of objects and measurement of geometric dimensions such as length. Background technique [0002] At present, laser scanning is usually used for 3D acquisition of large objects, but laser scanning requires special calibration of the object, setting multiple calibration points on the object, and the calibration process is cumbersome. For example, when scanning the vehicle shell, the use of laser scanners relies too much on the calibration accuracy, so the entire calibration work will last for one or two days, and the work efficiency is extremely low. And it is not suitable for outdoor operation due to weather changes. However, traditional devices that use image photography for 3D acquisition are usually only suitable for capturing small objects. In order to photograph larger objects, corresponding exploratio...
