Abstract
The invention provides a moving object linear array monitoring system comprising a line frequency control unit, a linear array camera and an image processing unit. The image processing unit is respectively connected with the linear array camera and the line frequency control unit. The line frequency control unit acquires moving object speed information and other attribute information to generate corresponding line frequency trigger signals and image capture information and transmits the line frequency trigger signals and the image capture information to the image processing unit. Line frequency of the linear array camera is controlled via the image processing unit, and dynamic exposure is performed through combination of brightness of the acquired images and image acquisition is performed on a moving object so that complete images required by users and metadata are synthesized. The images and the metadata can be transmitted to far-end storage equipment via a network according to configuration. An image transmitting and receiving optical transceiver does not need to be arranged at the field or the far-end, and a workstation for image processing does not need to be arranged in a machine room so that corresponding direct cost of hardware spending can be saved and indirect cost of machine room space and electricity utilization can be saved.
