The invention provides a video security monitoring device and a monitoring method based on the same, and belongs to the field of video monitoring. The video security monitoring device comprises a first camera, a second camera, a hyperboloid reflector, a singlechip and a turning regulation mechanism; a field angle of a lens of the first camera can cover the hyperboloid reflector, the second camerais connected with the turning mechanism, and the turning mechanism can drive the second camera to horizontally rotate so as to regulate a horizontal azimuthal angle of the second camera; meanwhile, the turning mechanism can also drive the second camera to rotate in a vertical direction so as to regulate a pitch angle of the second camera; and the singlechip can acquire image information acquired by the first camera and the second camera and calculate out an azimuthal angle and a pitch angle which need to be subjected to detail monitoring, and the singlechip carries out detail linkage monitoring by controlling the turning mechanism to drive the second camera to turn to the direction so as to implement the characteristic of giving consideration to both global and detail monitoring.
Description
technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video security monitoring device and a monitoring method based on the device. Background technique [0002] Panoramic imaging technology uses a special imaging device to obtain a hemispherical field of view greater than 180 degrees or a spherical field of view of 360 degrees in the horizontal or vertical direction. Panoramic imaging detection technology is a new type of imaging technology that has grown up with the development of binary optics, large array staring imaging devices and image correction technology. Its significant difference from traditional imaging detection systems is its super large field of view. The implementation methods of panoramic imaging system mainly include fisheye lens, multi-camera splicing and catadioptric type. [0003] The fisheye lens uses a front negative lens to achieve ultra-wide-angle imaging. The technology is mature. At present, t...
