Abstract

The invention discloses a high speed video data acquisition display system and a display method. The high speed video data acquisition display system comprises an FPGA controller and an alarming module connected with the FPGA controller, and the FPGA controller is connected with an OV7607camera by a camera configuration module and an SCCB bus. The OV7607 camera is used to transmit the acquired data information to the FPGA controller, which is connected with a projector/display by a VGA interface, and is connected with a CPU by a JTAG interface. The front segment camera (OV7670) is used for data acquisition, and is used to store the data in the internal RAM of the FPGA. The FPGA is used to realize fast reading/writing and transceiving control, and under control of a Nios II, the CPU is used to control the acquired data on the VGA display screen. A verilog hardware description language is used to initialize the SCCB bus, and the data acquired by the camera is stored in the internal RAM of the FPGA, and under excitation of clock pulses, the real-time data information is stored constantly, and high matching compatibility is achieved, and then a high efficiency and high speed data acquisition function is realized.

Description

technical field [0001] The invention relates to the technical field of network video monitoring, in particular to a high-speed video data acquisition and display system and display method.
