Problems solved by technology

Due to the limitation of existing sensor pixels, it cannot meet the functions of large-scale monitoring and target (such as license plate, face) recognition at the same time
For example, the existing panoramic camera can perform panoramic monitoring, but the target recognition distance is very short (less than 3m)

Abstract

The invention discloses a multi-lens camera device and a monitoring system, and belongs to the technical field of the imaging. The multi-lens camera device comprises multiple lens groups, each lens group comprises multiple lenses arranged in a line, the multiple lenses included by each lens group have the same focal length, and the same focal length is the focal length of the lens group; multiplelens groups are orderly arranged on a vertical direction, and the focal lengths of at least one lens groups are different; and the pictures shot by multiple lenses included by each lens group can be spliced into a complete picture. Through the multi-lens camera device disclosed by the embodiment of the invention, since the different lens groups with different focal lengths cover different regionsin the monitored range, the targets distributed on different distances can present sharp images, thereby performing effective target identification in large depth of the monitored range, namely, the identification capacity on a monitored target is effectively improved when the large-range monitoring is satisfied.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to a multi-eye camera device and a monitoring system. Background technique [0002] Surveillance cameras have been widely used in all aspects of people's lives. Usually, a camera is equipped with a lens, and the larger the field of view of the lens, the shorter the focal length. Due to the limitation of existing sensor pixels, it cannot satisfy the function of large-scale monitoring and target (such as license plate, face) recognition at the same time. Such as the existing panoramic camera, although it can perform panoramic monitoring, the distance of target recognition is very short (less than 3m). Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a multi-eye camera device and a monitoring system that improve the ability to recognize targets within a monitored long-depth range. [0004] Specifically, the...
