【Abstract】 In the multi-channel image acquisition system, USB2.0 interface is used to transfer the mass data. With high speed, flexible connection and universal interface, USB is more suitable for the communication to PC than the image-acquisition card. The design of multi-channel image acquisition system is discussed, including the design of USB hardware, firmware and application software. The application software uses multithreading to achieve the image’s real time display and storage.更多还原
