A three-dimensional model-based measuring device and method

Abstract

The invention discloses a measuring device based on a three-dimensional model, which comprises a first guide rail (2) and a second guide rail (3) fixedly connected to a headband (1) sequentially from near to far, connected in a translational and rotatable manner Two internal cameras (10) on the first guide rail (2) corresponding to the eyes of the user, and two external cameras (27) connected to the second guide rail (3) in a translational and rotatable manner and corresponding to the eyes of the user ). According to the measurement device based on the three-dimensional model of the present invention, the user can also obtain good three-dimensional model measurement results, real stereoscopic vision and more immersive augmented reality experience when turning the eyeballs, so that the user can pass through the three-dimensional model in the augmented reality scene. The model performs more accurate measurement of the measurement object and more accurate virtual manipulation of the three-dimensional model, and by adjusting the center of gravity of the device, the user feels more comfortable when wearing the device for a long time and avoids the damage of the device to the user's body.

Description

technical field [0001] The invention relates to the technical field of measurement based on a three-dimensional model, in particular to a measurement device and method based on a three-dimensional model. Background technique [0002] The computer-aided measurement technology using optical measurement adopts non-contact scanning measurement, which greatly improves the applicability of optical non-contact scanning measurement based on three-dimensional model. Commonly used non-contact measurement methods include: laser scanning method (laser triangulation method and three-dimensional model-based measurement laser ranging method), structured light method, image analysis method and methods based on sound waves and magnetism, among which structured light method is considered It is the most mature 3D shape measurement method based on 3D model measurement. Structured light scanning is mainly composed of a structured light projection device, a camera, an image acquisition and proce...

Problems solved by technology

[0003] At present, the non-contact 3D scanning technology at home and abroad mainly adopts the handheld articulated arm scanning method or the robotic arm scanning method based on the 3D model. Handheld 3D scanning expands the scope of application of 3D scanning to a certain extent, but handheld scanning has The problem of unstable measurement based on the 3D model, low scanning efficiency, and increased operational error; the automatic scanning of the robot arm overcomes the problem of unstable measurement based on the 3D model of the handheld scanning to a certain extent, and improves the scanning efficiency.
