Embodiment Construction

[0020] The invention uses FPGA to manage the acquisition and processing of the infrared camera carried by the unmanned reconnaissance robot and the four-channel visible light camera, uses the serial communication bus to receive the control instructions sent by the control terminal, and designs the hardware logic circuit according to the cruise display mode and navigation display mode , directional reconnaissance display mode and image enhancement display mode seamlessly stitch and superimpose multi-source videos, and integrate them into a PAL format video display on the main display of the control terminal; use iterative fast bilateral filtering algorithm to enhance the input video before displaying Processing, removing the fog interference in the picture and zooming in on detailed information, to achieve all-round acquisition and control of the battlefield situation. The implementation details are as follows:

[0021] 1) Decode the four PAL standard cameras carried forward, b...

Abstract

A low-latency omni-directional navigation video multi-mode display control method comprises the following steps: (1) carrying out video decoding on four PAL cameras carried by a reconnaissance robot through a multi-path video decoding chip to get four video data flows in accordance with the BT.656 protocol, converting an LVDS differential signal of a non-standard infrared spectral camera mounted at the front end of the robot into a 384*288 50HZ single-end digital video signal through an LVDS receiving chip, receiving a control instruction sent by an operation end through a serial communication bus, and analyzing the instruction format; (2) displaying videos in different video display modes according to the analyzed instruction format; and (3) encoding a BT.656 video processed in different video display nodes through a PAL video encoding chip, and generating a PAL analog output video. According to the invention, the battlefield situation can be acquired and controlled in an all-round manner.

Description

technical field [0001] The invention belongs to the technical field of embedded computer video processing, and relates to a low-latency omnidirectional navigation video multi-mode display control method. Background technique [0002] Unmanned reconnaissance robots are used to enter unknown, inaccessible or highly dangerous areas to perform reconnaissance tasks. They have a wide range of application requirements in space exploration, dangerous environment detection and sampling, anti-terrorism and chemical defense, and are research hotspots in the field of robotics. Since the unmanned robot is in a state of human-machine separation during work, the robot is often in a work site where the operator cannot see. The operator can only understand the robot's environment, movement, position, navigate through the human-machine interface, and control the robot to perform reconnaissance and target search. The number and types of sensors carried by robots are increasing. It is necessar...
