摘要： A surveillance system (10) for monitoring movement in a region of interest (18) is described. The surveillance system (10) includes: An image capturing system (12) having a field of view (16) including a region of interest (18), and adapted to capture an image of the region of interest (18). An image processing system (78) configured to process a time-sequential series of images of the field of view from the image capturing system such that at least a portion (52, 53, 54) of each processed image (50) is analysed for detecting movement within the region of interest (18). The image capturing system (12) is configured to capture, in each image, different apparent magnifications of respective zones (20, 22, 24) within the region of interest (18) in the field of view (16) that are at different distances from the image capturing system (12) such that an object (60) in at least one position in at least two of said zones has substantially the same apparent size in the images.
