Abstract

The embodiment of the invention provides an image acquisition method and image acquisition equipment. The image acquisition method is applied to the image acquisition equipment comprising a first chip, zoom lenses, image sensors, zoom motors and focusing motors. The number of the first chip is one. According to the image acquisition equipment with the two zoom lenses, the two zoom lenses have different zoom ranges, and an overlapped focal length range exists between the zoom ranges of the two lenses, and the two zoom lenses comprise a first short zoom lens and a second long zoom lens; the number of the image sensors is two, and the two image sensors correspond to the two zoom lenses respectively, and the two image sensors are in communication connection with the first chip; and the numberof the zooming motors is two, and the number of the focusing motors is two, and the two zooming motors and the two focusing motors are in communication connection with the first chip. Through superposition of zoom ranges of the two zoom lenses, the focal length range of the image acquisition equipment is expanded on the premise of not increasing the volume of a single lens.

Description

Technical field [0001] The present invention relates to the technical field of video monitoring, in particular to an image acquisition method and image acquisition equipment. Background technique [0002] With the development of computer, network and image processing technology, video surveillance technology has been widely used. Since video surveillance has diversified image collection requirements, such as panoramic image collection and key target close-up collection, etc., in order to meet the diversified image collection requirements, cameras used for video surveillance often require a wide focal length range. [0003] In order to expand the focal length range of the camera, the corresponding technology usually adopts methods such as increasing the lens length of the camera or the number of optical lenses in the lens. However, the above method has the problems of extremely high hardware cost, very large lens volume, and low yield rate of larger lenses. Summary of the inventio...
