Abstract

The invention discloses a system for multithreading real-time construction of an orthoimage semantic map. The system comprises an unmanned aerial vehicle photoelectric pod, an AI edge computing device, a radio station and a comprehensive control computer. The unmanned aerial vehicle photoelectric pod is used for collecting aerial images of the ground terrain; the AI edge computing device is used for constructing a two-dimensional orthoimage map according to the aerial image and identifying and segmenting environmental elements; the radio station is used for transmitting the segmentation results of the two-dimensional orthoimage map and the environmental elements to the comprehensive control computer; and the comprehensive control computer is used for carrying out color separation marking on the two-dimensional orthoimage map according to the segmentation result to form a two-dimensional orthoimage semantic map. According to the multi-thread system for constructing the orthoimage semantic map in real time, the AI edge computing device is constructed on the unmanned aerial vehicle, and construction of the two-dimensional orthoimage map is transferred to the AI edge computing device from the ground workstation, so that the real-time performance and timeliness of image splicing are higher.

Description

technical field [0001] The invention relates to the technical field of individual soldier reconnaissance, in particular to a system for constructing an orthophoto semantic map in real time with multiple threads. Background technique [0002] In recent years, with the in-depth exploration of the UAV aerial survey field, UAV oblique photography technology has developed rapidly. Using the platform based on UAV oblique photography, you can quickly obtain a large number of video image geographic details of the target area, and then transmit the video and image information to the ground workstation through high-speed image transmission technology, and process the acquired map information to Help practitioners understand the actual situation of the aerial survey area more comprehensively and intuitively. Due to its low cost, high efficiency, flexible maneuverability, and simple deployment, the real-time map mosaic generation technology based on UAV aerial images is widely used in ...
