Problems solved by technology

However, the above-mentioned camera array can only adjust the rotation of the camera. When adjusting the concentricity, the positioning process is difficult to control, and the array cannot be positioned to the optimal spatial attitude; and the registration depends entirely on the ideal degree of the collected video, and the calculation accuracy is poor.

Embodiment Construction

[0078] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0079] In order to improve the adjustment of the camera array in the optimal attitude and improve the control accuracy. An embodiment of the present invention provides a camera array, which facilitates adjustment of the postures of cameras in the camera array, thereby facilitating video registration and improving the effect of video splicing.

[0080] In a specific example, such as figure 1 , figure 1 It shows a schematic structural d...

Abstract

The present invention relates to the field of multimedia technology, and discloses a camera array, which includes a support structure and a plurality of cameras arranged in an array, and the cameras in the camera array can slide along their axis and move horizontally The positions are adjusted so that the optical centers of the cameras of the camera array are coplanar or collinear. In the above technical solution, the adjustment of the position of the camera is realized through the provided supporting structure, so that the optical centers of the cameras are coplanar or collinear, and the effect of splicing images adopted by the cameras is improved.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular to a camera array. Background technique [0002] With the development of multimedia technology, a single camera can no longer meet people's requirements. Various applications such as panoramic video, stereo camera, augmented reality, visual measurement, 3D reconstruction, and synthetic aperture imaging require multiple cameras to work together. The combination of these cameras in a specific posture is a camera array. [0003] The camera array must be positioned by certain means, and its goal is to facilitate video registration as much as possible, that is, to achieve the optimal positioning posture. The camera array (collected video combination) must be registered by certain means, and its goal is to obtain the ideal spatial consistency as possible, that is, to achieve the optimal registration state. [0004] Video stitching is an important application based on camera ...
