Abstract

The invention provides an intelligent field unmanned plane search and rescue method and system based on double source video analysis. The intelligent field unmanned plane search and rescue method based on double source video analysis includes the steps: utilizing an infrared image to extract the candidate target and the region-of-interest ROI; using an improved deep convolutional neural network target detection framework Single-shot Multi-box Detector to perform optical target detection on the target region so as to locate the personnel to be searched and rescued; after locating the personnelto be searched and rescued, accurately delivering first aid materials; during the flying process, using LiDAR to perform autonomous obstacle avoidance; and based on detection of AprilTag, performing accurate autonomous landing. Mutual assistance between infrared and optical video analysis can effectively overcome the illumination factor, the shielding factor and other factors, so that the intelligent field unmanned plane search and rescue method and system based on double source video analysis can work all time so as to guarantee the search and rescue efficiency.

Description

technical field [0001] The invention belongs to the technical field of image processing and unmanned aerial vehicles, and in particular relates to key technologies for field search and rescue of unmanned aerial vehicles, including target detection, autonomous obstacle avoidance and autonomous fixed-point landing. Background technique [0002] With the improvement of people's living standards, the forms of people's travel and entertainment are becoming more and more diverse. What followed was an increase in the demand for field rescue. Field search and rescue is extremely difficult. Generally speaking, the mental and physical pressure of people lost in the field rises sharply, and physical energy consumption accelerates. Especially after encountering natural disasters (earthquakes, flash floods, landslides, etc.), the human body may have been damaged. Therefore, field search and rescue It is a race against time, every second counts. But there are many factors hindering the ...
