Embodiment 1

[0032] See figure 1 , The portable non-contact digital device for endoscopic measurement of the inner cavity shape of an object includes an inner cavity acquisition mechanism (4), a control box (1) and a motion support mechanism. It is characterized in that: the inner cavity acquisition mechanism (4) is fixed to one side of the control box through a motion support mechanism to complete the point cloud collection of the inner cavity model of the object under test; the motion support mechanism realizes the movement of the inner cavity acquisition system And support; the inner cavity acquisition mechanism (4) has a mirror and a laser rangefinder, the laser beam of the laser rangefinder is refracted by 90° through the mirror, and the radius value of the inner cavity of the measured object is measured, combined with rotation The angle and the movement value in the up and down direction can be calculated in the host computer to obtain the inner cavity point cloud; the control box (1) ...

Embodiment 2

[0033] The second embodiment, this embodiment is basically the same as the first embodiment, and the special features are:

[0034] See Figure 1-Figure 4 The inner cavity acquisition mechanism (4) includes a laser rangefinder (10), an L-shaped laser rangefinder support plate (11), a round tube (12), a mirror (13), and a mirror bottom plate (14) . The laser rangefinder (10) is fixed on the L-shaped laser rangefinder support plate (11), and is used in the laser rangefinder protective cover (9) to measure the distance from the laser emitting point to the cavity; L The support plate (11) of the type laser rangefinder adopts an L-shaped integrated design to ensure the perpendicularity of the laser beam to the horizontal plane and the parallelism of the lower circular tube and the laser beam; the circular tube (12) is fixed on the L-shaped laser rangefinder The lower end of the support plate (11) has a length greater than the depth of the inner cavity of the object to be measured; t...

Embodiment 3

[0038] Such as figure 1 As shown, the portable non-contact type endoscopic measurement digital device for the inner cavity shape of an object includes an inner cavity acquisition mechanism (4), a control box (1) and a motion support mechanism. The inner cavity collection mechanism is fixed on one side of the control box (1) to complete the inner cavity collection work. The inner cavity acquisition mechanism obtains the radius value of the inner cavity through the laser rangefinder (10), and the inner cavity point cloud can be reconstructed by combining the rotation angle and the movement value in the up and down direction. The control box provides power for the motion and laser rangefinder (10) and realizes the control of the motion. The equipment is used for three-dimensional scanning and reconstruction of the internal cavity of an object, so as to further carry out the measurement of the internal cavity of the object, archaeological research and the establishment of a digital...

Abstract

The invention relates to a portable non-contact digital device for peeping and measuring the inner cavity morphology of an object. The device includes an inner cavity collection mechanism, a control box and a motion support mechanism. The inner cavity collection mechanism is fixed on a side of the control box to complete the inner cavity collection for an object. The motion support structure realizes the motion and support of the inner cavity collection mechanism. The inner cavity collection mechanism and measures the radius value of the inner cavity by refracting a laser beam of a laser range finder by 90 degrees with a reflective mirror, and can calculate the inner cavity point cloud in a host computer by combining the rotated angle and a motion value in an up and down direction. The control box supplies power for the motion mechanism and the laser range finder, and achieves the control of the motion. The device is used for three-dimensional scanning and reconstruction of the inner cavity morphology of the object, so as to further measure the inner cavity of the object, achieve archaeological research and establish a digital museum.

Description

Technical field [0001] The present invention is a digital device applied in the field of object measurement and protection, in particular a portable non-contact type endoscopic measurement digital device for the internal cavity of an object, which is mainly used for three-dimensional scanning and reconstruction of the internal cavity of an object, thereby further Carry out object cavity measurement, archaeological research and establishment of digital museum. Background technique [0002] Digital processing and measurement of precious cultural relics or important parts and other objects is of great significance. Especially for cultural relics, through three-dimensional digitization, a network-based digital museum system can be built, which can better solve the rich exhibits and the limited exhibition space and time. The contradiction between them can further open up new areas of museum collection protection, research and display, and also realize the modernization of museum manag...
