Its disadvantage is that there are too many processors in the whole system. Although the embedded human-computer interaction board is used to replace the PC to complete the human-computer interaction, its processing speed will still be limited. In practical applications, its processing capacity can only achieve 200fps, 640*240 pixel image acquisition

The invention relates to an image sensing device, an acquisition processing device and an object motion image acquisition system. In order to solve the shortcomings of the traditional object motion image acquisition system, such as high cost, complex system structure, and complicated signal processing process, the object motion image acquisition system, It includes an image sensing device and an image acquisition and processing device; the image sensing device converts the captured image into an LVDS signal and outputs it to the image acquisition and processing device for image processing. The image sensing device of the present invention directly converts the optical signal into a low-voltage differential signal and outputs it to the image acquisition and processing device for processing, the signal transmission process is simple, and no encapsulation and decapsulation are required. The image sensing device adopts the global shutter to collect the image of the high-speed moving object, which is clear without smear and easy to identify. The image acquisition and processing device adopts a single chip including FPGA and ARM functions, has a simple structure, and realizes the integration of image acquisition and processing.
Description
technical field [0001] The invention relates to the field of image acquisition, and more specifically relates to an image sensing device, an acquisition processing device and an object moving image acquisition system. Background technique [0002] Traditional object motion image acquisition systems have disadvantages such as high cost, complex architecture, and complex signal processing. For example, the existing patent CN105611270A discloses a binocular autostereoscopic display system, including a binocular camera, an interface conversion circuit, an FPGA acceleration circuit and an autostereoscopic display. The binocular camera includes an image processing board, a sensor board and a lens. In practice, the purchase of cameras to assemble the system would incur significant expense. The signal processing flow of the system is as follows: first convert the original signal to HDMI signal, and then convert the HDMI signal to LVDS signal through the conversion circuit. The me...
