Unmanned plane based geological disaster data collection processing method and device

Abstract

The invention provides an unmanned plane based geological disaster data collection processing method and device. High-precision image distortion correction is carried out on remote sensing image data collected by an unmanned plane, and optimizing pre-processing is carried out on the remote sensing image data; control points that satisfy the precision requirement are used to carry out aerial triangulation encryption on the remote sensing image data, exterior orientation elements of each remote sensing image data are obtained, and orthoimage data and DEM data are further obtained, and a geological disaster control service model is established. Image data of the unmanned plane and DEM data are collected automatically in processes, the technical difficulty in processing the image data of the unmanned plane and the DEM data is overcome, a standard data drafting flow is formed, the effectiveness is improved, and the method and device are convenient to popularize and apply; data information obtained by the method and device meets the demand of a geological disaster control service application system, the data input flow in geological disaster investigation and emergency process is thus simplified, and the method and device are timely and efficient.

Description

technical field [0001] The invention relates to the technical field of geological disaster investigation, monitoring, survey design and emergency treatment, in particular to a method and device for collecting and processing geological disaster data based on an unmanned aerial vehicle. Background technique [0002] In recent years, the environmental conditions in geological disaster areas have deteriorated sharply, coupled with the frequent occurrence of local heavy rainfall and various extreme climates, as well as the increasing depth and breadth of human engineering activities (blasting, excavation, stacking, slope cutting, etc.) The possibility and frequency of new geological disasters are increasing, and the situation of prevention and control work is severe and the task is arduous. For a long time, the basic images and DEM data used in geological disaster investigation, monitoring, survey design and emergency response are usually obtained through traditional surveying an...

Problems solved by technology

From the acquisition of raw data to the generation of expected products, a large number of software and hardware systems and technical personnel must work together, including data receiving devices, switching devices, storage devices; acquisition systems, processing systems, output systems; image interpretation personnel, GIS data processing personnel , image drawing personnel, etc., in which the data processing system includes professional drawing software (such as PHOTOSHOP), remote sensing image processing software (such as ERDAS / ENVI) and GIS data processing software (such as ARCMAP), so that the response to sudden and urgent geological disasters It is impossible to make a corresponding disaster emergency plan in time, which delays the best time for disaster relief. Therefore, it is urgent to provide a geological disaster data that can automatically collect and process drone images and DEM data, and form a data standardized drawing process.
