Embodiment 1

[0068] Such as figure 1 As shown, a three-dimensional reconstruction device based on monocular stereo vision, including a plane base 1, a screw mounting base 2, a right slide bar 3, a lead screw 4, a left slide bar 5, an elevating platform 6, and a screw upper mounting Seat 7, rotating handle 8, steering gear mount 9, steering gear 10, crank 11, laser mount 12, crosshair laser 13, telescoping rod 14, camera gripper 15, industrial camera 16 and computer 17.

[0069] The upper surface of the plane base 1 is a smooth plane, and its R a The value is preferably 1.6, the upper surface can be used to place the object to be measured, and the lower surface has grooves, which can make the surface finishing area of ​​the lower surface of the plane base smaller, reduce processing difficulty and save cost. The lower mounting base 2 of the screw is drilled with five holes on the same plane, one is a bearing hole, and a bearing is housed in the bearing hole, two through holes are arranged s...

Embodiment 2

[0097] As a description of Embodiment 2 of the present invention, only the differences from Embodiment 1 above will be described below.

[0098] This embodiment is another three-dimensional reconstruction device based on monocular stereo vision, such as Figure 4 As shown, the steering gear mounting base 9a is fixedly connected to the lifting platform 6 through screw connections; the steering gear 10a is fixedly connected to the steering gear mounting base 9a through screw connections. The crank 11a is fixedly connected to the steering wheel of the steering gear 10a through threaded connection; the line laser jaw 12a is fixedly connected to the crank 11a through a threaded connection. The line laser 13a is clamped by the line laser jaw 12a, and is fixedly connected to the line laser jaw 12a. The telescopic rod 14a is connected to the crank 11a through a hinge. When the hinge is released, the telescopic rod 14a can rotate around the hinge to adjust the horizontal distance betw...

Abstract

The invention discloses a three-dimensional reconstruction device and method based on monocular stereoscopic vision which are suitable for a cross laser and a linear laser. The invention comprises a plane substrate, a lead screw lower installation seat, a right sliding rod, a lead screw, a left sliding rod, a lifting platform, a lead screw upper installation seat, a rotating handle, a steering engine installation seat, a steering engine, a crank, a telescoping rod, a camera clamping jaw, an industrial camera and a computer. The invention is simple in structure and wide in application, the geometrical relationship among a plurality of components is adjustable, various different technical schemes can be experimented on one device by adjusting the height of the lifting table and adjusting thegeometrical position relationship between the laser and the industrial camera, and compared with a traditional three-dimensional reconstruction device, the three-dimensional reconstruction device hasthe advantages of being simple in structure and convenient to use. A linear motion transmission chain part for realizing the relative linear motion of a linear laser and a to-be-measured object is removed, design difficulty and the design cost are reduced,. Redundant errors introduced by the linear motion transmission chain are also avoided, and the linear motion transmission chain has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional reconstruction, and in particular relates to a three-dimensional reconstruction device and method based on monocular stereo vision. Background technique [0002] At present, most of the measurement and 3D reconstruction devices based on line laser monocular stereo vision adopt the technical solution of making the line laser and the object to be measured move in a relative straight line, so as to achieve the purpose of scanning and obtaining the surface information of the entire object to be measured . [0003] For example, the Chinese patent document with the publication number CN111389777A discloses a surround-type three-dimensional reconstruction mechanism based on line laser scanning, including a base, and two boxes are arranged on the top of the base, and the bottoms of the two boxes pass through slide rails. The two boxes are movably connected with the base, and the two boxes are e...
