Unmanned aerial vehicle oblique photographing infrared three-dimensional imaging system and modeling method thereof

Abstract

The invention discloses an unmanned aerial vehicle oblique photographing infrared three-dimensional imaging system and a modeling method thereof. The system comprises an infrared loading unit, a vehicle-mounted image transmission unit, a POS unit, a ground management unit and a three-dimensional modeling processing unit. The infrared loading unit is used for imaging of a ground object and transmitting an image to the vehicle-mounted image transmission unit; the POS unit is used for measuring position and attitude information of the system; the vehicle-mounted image transmission unit is used for receiving the image transmitted by the infrared loading unit and the position and attitude information measured by the POS unit and transmitting the image and the position and attitude information to the ground management unit; and the three-dimensional modeling processing unit is used for establishing a three-dimensional model according to the image and the position and attitude information of the POS system which are received by the ground management unit. According to the system, infrared image of the object to be measured is acquired and three-dimensional modeling is performed on the image so that accurate positioning and scientific decision making can be performed by technical personnel according to the three-dimensional model.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to an infrared three-dimensional imaging system and a modeling method for oblique photography of an unmanned aerial vehicle. Background technique [0002] Tilt photography technology is a high-tech developed in the field of international surveying and mapping in recent years. Different from vertical angle shooting in the past, tilt photography is equipped with multiple sensors on the same aviation platform, and collects images from one vertical and four oblique angles at the same time. Through 3D modeling technology, multi-angle oblique images and vertical images are constructed into a 3D model of ground objects and scenes, which introduces users to intuitive and real scenes that conform to human vision. [0003] At present, most of them use visible light cameras for imaging, and analyze the imaging results to obtain 3D models. However, based on this imaging technolog...

Problems solved by technology

However, based on this imaging technology, it is impossible to make accurate predictions on the temperature changes of objects, the detection of fire sources, the detection and tracking of suspicious targets, etc.; it is not easy to find in scenarios such as animal migration monitoring at night, personnel search and rescue during earthquakes, and night investigations. Targets cannot be detected at night, etc. In the above scenarios, the technology of tracking visible light cannot enable technicians to analyze the target according to the image
