Adjusting method in co-optical-center videography and co-optical-center camera system

Abstract

The embodiment of the invention discloses an adjusting method in co-optical-center videography and a co-optical-center camera system, relating to a video-processing technology. The adjusting method can finely adjust the shooting direction of a video camera to align visual angle edges of the video camera and adjust the shooting direction of a Sensor while ensuring that the optical center of the video camera keeps a constant position and is easy to adjust and convenient to operate, and the adopted equipment has small size and low system cost. The adjusting method in co-optical-center videography, which is provided by the invention, comprises the following steps of: arranging a homocentric universal joint between an outer shell of a video camera core and a bracket so that the video camera core and the bracket are connected by the homocentric universal joint, wherein the rotating center of the homocentric universal joint coincides with the practical optical center of the video camera core; and adjusting the video camera core by rotating the homocentric universal joint so as to adjust co-optical-center videography. The embodiment of the invention is suitable for co-optical-center videography occasions.

Description

technical field [0001] The invention relates to video processing technology, in particular to an adjustment method in common optical center imaging and a common optical center imaging system. Background technique [0002] With the development of video processing technology, video images have developed from SDTV to HDTV, computer images have developed from VGA to UXGA, and area array image sensors have also developed from hundreds of thousands of pixels to several million pixels. Image resolution continues to improve, as do lens angles of view. [0003] However, the development of technology still cannot keep up with people's demand for high-resolution wide-angle images. Also, the larger the viewing angle, the larger the geometric distortion of the image. Therefore, for more than half a century, how to use existing resolution image sensors and geometric distortion-free lenses with small viewing angles to stitch moving or still images with higher resolution and larger viewin...

Problems solved by technology

[0005] In the process of image stitching, there are deviations in the edges of the viewing angles of adjacent cameras, and the shooting orientation of each image sensor (Sensor) cannot be guaranteed to be consistent. The method for adjusting the optical center position of the camera and the shooting orientation of the Sensor provided by the prior art uses The size of the equipment is too large and the cost is too high; and the operation method is very complicated, especially when adjusting the shooting position of the Sensor, the optical center will also move accordingly, making the adjustment operation extremely difficult
