Embodiment 1
[0033] like figure 1As shown, the present invention is an embedded multi-channel video image acquisition and parallel processing system and method, comprising a multi-channel image acquisition module, an FPGA and a DSP; the multi-channel image acquisition module collects image data and sends it to the FPGA; the multi-channel image acquisition module collects image data and sends it to the FPGA; The FPGA buffers the image data, processes it, and sends it to the DSP; the DSP is a multi-core DSP, and multiple cores of the DSP perform parallel processing on the image data sent by the FPGA.
[0034] When this embodiment is implemented, the present invention is mainly used for multi-target search and tracking in the air. When performing multi-target search in the air, multiple channels are required for image acquisition, and images of multiple channels need to be quickly processed to facilitate subsequent follow-up. The system performs image synthesis and takes target disposal measu...
Embodiment 2
[0036] In this embodiment, on the basis of Embodiment 1, the FPGA includes a data buffer unit, a data priority arbitration module, a multi-channel video inter-chip transmission module, and a DDR3 unit; the data buffer unit buffers the data sent by the multi-channel image acquisition module. Image data; the data priority arbitration module compares the valid data information of each video source, and selects a video source to send to the DDR3 unit; the DDR3 unit performs read and write control to complete data buffering. The multi-channel video inter-chip transmission module realizes interaction with the DSP.
[0037] When this embodiment is implemented, when searching for multiple targets in the air, images that need to be preferentially processed may appear, for example, images of targets appear. In this case, the data priority arbitration module needs to prioritize these image information in scheduling. This The invention performs arbitration through the priority of the mult...
Embodiment 3
[0039] On the basis of Embodiment 1, this embodiment further includes a display module; after the FPGA superimposes the image information in the cache and returns the image information after parallel processing by the DSP, the display module performs mosaic display or separate display.
[0040] When this embodiment is implemented, the image information processed by the DSP is generally added with marks such as gates / crosshairs, and information such as target positions to highlight the target in the image information. This is to superimpose the target information with the image in the cache, which can The target is prominently displayed and continuously framed and tracked.
