Multi-channel image capture system

A multi-channel image capture system, comprising:

• a signal conversion chip;
• a secondary FPGA chip which is connected to the signal conversion chip;
• and
• a plurality of secondary image information transmission channels which are all connected to the secondary FPGA chip, and the secondary image information transmission channels each having a primary FPGA chip, a camera interface unit connected to the primary FPGA chip, and a cache unit connected to the primary FPGA chip, wherein the primary FPGA chips are all connected to the secondary FPGA chip,
• wherein
• the camera interface unit is configured to be connected to an external camera and includes several camera interfaces;
• the primary FPGA chip is configured to receive, decode, and then write image data captured by the camera to the cache unit and is further configured to read the image data from the cache unit according to a read command from the secondary FPGA chip and transmit it to the secondary FPGA chip;
• the cache unit is configured to cache the image data;
• the secondary FPGA chip is configured to acquire the image data from the cache unit based on a priority and a capturing order and transmit it to the signal conversion chip;
• and
• the signal conversion chip is configured to be connected to a terminal to transmit the image data to the terminal.
