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.

The invention discloses a three-dimensional-model-based measuring device comprising a first guide rail (2), a second guide rail (3), two internal cameras (10), and two external cameras (27). The two internal cameras (10) are connected to the first guide rail (2) in a translatable and rotatable manner and correspond to the two eyes of the user; and the external cameras (27) are connected to the second guide rail (3) in a translatable and rotatable manner and correspond to the two eyes of the user. According to the three-dimensional-model-based measuring device, the good three-dimensional modelmeasurement result, real stereoscopic vision and immersive augmented reality experience can be obtained when the user moves the eyeballs; the user is able to measure a measured object precisely by using the three-dimensional model and carry out virtual operation on the three-dimensional model precisely in an augmented reality scene; and with adjustment of the center of gravity of the device, the user experience is improved when the user wears the device for long time and the injury on the body of the user by the device is avoided.
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...
