Embodiment 1

[0027] see figure 1 , an expandable portable multi-degree-of-freedom multi-eye camera bracket includes a base 1 and eight camera fixing units.

[0028] see image 3 The upper part of the base 1 is a horizontal connecting pipe, and the two ends of the connecting pipe are respectively provided with external threads; the lower part of the base 1 is a base mounting block with a trapezoidal cross section. Two ends of the connecting pipe are respectively connected with a camera fixing unit through threads.

[0029] see image 3 , The camera fixing unit includes a conduit 9, a slider 8, a camera mounting mechanism, a pair of connecting balls and a pair of nut covers. Both ends of the conduit 9 are respectively provided with external threads, and the slider 8 is ring-shaped and sleeved on the conduit 9 . A protrusion is provided on the outer circumference of the slider 8, and the protrusion is a stepped cylinder, and the diameter of the upper cylinder is greater than that of the l...

Embodiment 2

[0033] see Figure 4 , an expandable portable multi-degree-of-freedom multi-eye camera bracket includes a base 1 and four camera fixing units. Other structures are the same as the embodiment.

[0034] Wherein, by adjusting the first camera fixing unit and the first camera fixing unit, the lens of the first camera and the lens of the second camera are respectively directed to different directions.

Abstract

The invention discloses an expandable portable multi-degree-of-freedom multi-eye camera bracket. The invention belongs to the field of computer vision measurement technology and multi-eye camera three-dimensional measurement. Consists of more than one base and two or more camera fixing units. The base is a connecting pipe; the camera fixing unit includes a conduit, a ring-shaped slider, a camera mounting mechanism, a pair of connecting balls and a pair of nut covers; the two ends of each are respectively connected to a camera fixing unit by threads; the adjacent camera fixing unit Connect in turn through mating connections of nut covers and conduits. When in use, more than two cameras are respectively fixed on more than two camera installation mechanisms to realize free setting of the number of cameras. Among them, the connecting ball mechanism part can realize any angle adjustment between adjacent cameras, and the camera platform part can realize the adjustment of the left and right position, pitch angle and rotation angle of the camera. The invention is simple and practical, can be expanded freely, can be installed with different numbers of cameras, and is suitable for machine vision systems.

Description

technical field [0001] The invention belongs to the fields of computer vision measurement technology and three-dimensional measurement of multi-eye cameras, and in particular relates to an expandable portable multi-degree-of-freedom multi-eye camera bracket. Background technique [0002] In 3D reconstruction based on computer vision, in order to solve the problems of limited field of view of the binocular camera method, difficulty in matching points of the same name between binocular cameras, and low resolution, it is currently possible to solve the problem of binocular camera measurement by increasing the number of cameras. Due to the limitations of the method, by building a multi-camera measurement system, the measurement field of view can be expanded, the accuracy and stability of matching points with the same name between different cameras can be improved, and the collaborative and efficient visual measurement between multiple cameras can be realized. At present, multi-c...
