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-camera support, and belongs to the field of computer vision measurement technology and multi-camera three-dimensional measurement. The support comprises one or more bases and two or more camera fixing units, the base is a connecting pipe, the camera fixing units comprise guide pipes, annular sliding blocks, camera mounting mechanisms, a pair of connecting balls and a pair of nut covers, each of the two ends of the connecting pipe are connected with one camera fixing unit through threads, and the adjacent camera fixingunits are sequentially connected through matched connection of the nut covers and the guide pipes. When in use, two or more cameras are fixed on two or more two camera mounting mechanisms, so that the number of the cameras can be freely set. The connecting ball mechanism parts can realize arbitrary angle adjustment between the adjacent cameras, and a camera platform part can realize adjustment ofthe left and right position, pitching angles and rotating angles of the cameras. The support is simple and practical, capable of being freely expanded, capable of being used for installing differentnumbers of cameras, and suitable for a machine vision system.

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...
