Video surveillance system, has mobile mirror generating variable circular image on sensor of camera, where circular image is represented irrespective of panoramic scene along site and azimuth position of mobile mirror

摘要

The system has a fixed convex mirror (2) with a shape for generating an annular image on an image sensor of a camera (1), where the annular image represents a panoramic scene with a field having 360 degrees on a horizontal plane and with a variable vertical field. A mobile mirror (3) is located at a center of the fixed mirror and generates a variable circular image on the sensor. The circular image is located at a center of the annular image and represented irrespective of the panoramic scene along a site and azimuth position of the mobile mirror.
