Wireless image acquisition system based on FPGA

Abstract

The invention discloses a wireless image acquisition system based on an FPGA, and belongs to the technical field of image acquisition. The wireless image acquisition system comprises an ARM wireless control module, an image acquisition module, an image processing module, an FPGA processing module, a network data transmission module, a wireless network card module, an image splicing module and a display module, wherein the ARM the wireless control module is in communication connection with the image acquisition module; the image acquisition module is connected with the image processing module through an internal network; the image processing module is in communication connection with the FPGA processing module; the FPGA processing module is wirelessly connected with the network data transmission module; the network data transmission module is wirelessly connected with the wireless network card module. According to the invention, repeated acquisition can be avoided, so that the image after image frame data is continuous is not easy to generate smear distortion, the image acquisition effect is improved, the influence on image display is avoided, huge images can be acquired, the application of the system is not limited, popularization of the system is facilitated.

Description

technical field [0001] The invention relates to the technical field of image acquisition, in particular to an FPGA-based wireless image acquisition system. Background technique [0002] With the rapid development of computer network transmission technology and communication technology, wireless long-distance video transmission has become a trend. This technology has been gradually applied in remote monitoring, aerial photography and teleconferencing. The currently used video monitoring systems are generally: Use a high-quality image sensor camera to transmit data in real time through the S-VIDEO terminal. This system requires a connection between the camera and the acquisition device. At the same time, the monitoring center must have a large storage space to store images and video clips. The system’s High real-time performance, but high energy consumption and high cost, so it is only suitable for security and monitoring in public places, and the FPGA-based wireless image acq...

[0002] With the rapid development of computer network transmission technology and communication technology, wireless long-distance video transmission has become a trend. This technology has been gradually applied in remote monitoring, aerial photography and teleconferencing. The currently used video monitoring systems are generally: Use a high-quality image sensor camera to transmit data in real time through the S-VIDEO terminal. This system requires a connection between the camera and the acquisition device. At the same time, the monitoring center must have a large storage space to store images and video clips. The system’s High real-time performance, but high energy consumption and high cost, so it is only suitable for security and monitoring in public places, and the FPGA-based wireless image acquisition system has become a suitable choice due to its low power consumption and reconfigurable characteristics

[0003] After retrieval, Chinese Patent No. CN201120476064.0 discloses an FPGA-based wireless image acquisition system, which cannot acquire huge images, which limits the application of the system and is not conducive to the promotion and use of the system. At the same time, continuous acquisition of image data cannot be achieved, and there is no guarantee The integrity of the image data, and when the general system moves to collect images, it is easy to cause the image to have distortion like smear, which makes the effect of image acquisition poor, so the display of image images brings the problem of system defects
