Abstract:
1. A camera arrangement having at least one wide angle camera for continuous surveillance of passengers in an elongated space of a bus or train corridor, comprising: a first wide angle camera; a second wide angle camera; and a mount configured to mount the first and second wide angle cameras on a ceiling of the elongated space such that the cameras are arranged back to back, are not aligned on one and the same axis and with each wide angle camera directed onto a respective distant area of the elongated space such that each wide-angle camera has a field of view of low distortion directed onto distant parts of space to detect objects with small angular distance to obtain good image quality without the need for equalization, and has a field of view of higher distortion directed onto closer parts of the elongated space to detect objects with large angular distance using a comparatively large numbers of pixels sufficient to obtain good image quality by equalization of said distortion, wherein the field of view of the first wide angle camera overlaps the field of view of the second wide angle camera in an area below the camera arrangement to allow for generation of one seamless image from two single images.
