Abstract

The embodiment of the invention discloses a method and a device for adjusting panorama imaging as well as a panorama imaging device. The method comprises the following steps: determining the panoramic angle and the pitch angle of a current region to be detected; determining the side length of a rectangular imaging device in the panorama imaging device; adjusting a round panorama image of a panoramic lens formed on a focal plane according to the side length of the rectangular imaging device as well as the panoramic angle and pitch angle of the current region to be detected so as to enable the diameter of the round panorama image of the panoramic lens formed on the focal plane is larger than the short side length of the rectangular imaging device. By utilizing the method provided by the embodiment of the invention, the pixel utilization ratio of the imaging device is effectively improved in the occasion that the panoramic requirement of the pitch angle is less than 360 degrees; and the imaging quality is improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a panoramic imaging adjustment method and device and a panoramic imaging device. Background technique [0002] The current panoramic monitoring equipment is mainly composed of panoramic lens and CCD / CMOS imaging components. The analog video signal output is connected to the panoramic video server, and the panoramic video server transmits the unfolded image to the monitoring room or directly to the monitor for monitoring. show. Panoramic camera is a new kind of panoramic monitoring equipment, without using multiple cameras, a single panoramic camera can realize 360-degree blind spot monitoring of a large space. figure 1 It is a schematic structural diagram of the principle structure for realizing 360-degree panoramic imaging in the prior art. As shown in the figure, the imager 102 is located on the focal plane 104 of the panoramic imaging lens, and the optical axis 103 ...
