Abstract

The invention discloses an ARM-FPGA coordinated wide-area video real-time fusion method and an embedded device. The ARM-FPGA coordinated wide-area video real-time fusion method includes reading the image file of the Linux operating system and starting the entire Linux embedded operating system. , and complete the initial configuration of the Linux kernel, file system, and device tree of the system and the loading of the video stream decoding library; obtain the first number of network camera video streams, and decode them based on the video stream decoding library to obtain the first number of video streams frame image; based on the lookup table file stored in the secure digital card, the frame image of the first number of videos is fused to obtain a panoramic image, wherein the lookup table file includes a first coordinate mapping table, a second coordinate mapping table and a weighted A list of fusion weights. Realize the use of lookup table files for the fusion of different scenes, monitoring angles of view, and location video images under the stitching method, which has good versatility.

Description

technical field [0001] The invention relates to the technical field of security monitoring, in particular to an ARM-FPGA coordinated wide-area video real-time fusion method and an embedded device. Background technique [0002] As an effective monitoring method, video network cameras have already played an irreplaceable role in many application areas such as urban security, public transportation management, production control, etc., especially the new generation of network camera IPC, which can encode and compress the collected analog video signals Digital signals are transmitted to the Web server through the network bus. Authorized users can directly use the browser to watch the video of the network camera in real time, and can also control the pan / tilt of the network camera to rotate the lens or operate the system configuration, making remote monitoring implementation and construction and maintenance more efficient. Simple. However, a single network camera can only collect...
