Photogrammetry and remote sensing comprehensive teaching method and system

Abstract

The invention discloses a photogrammetry and remote sensing comprehensive teaching method and a system. The method comprises the following steps that aerial images of a preset flight planning area are obtained and pre-treated, control points are distributed in the flight planning area according to the pretreated aerial images and control point distributing standards, the geographical coordinate measuring is conducted, exterior orientation factors of all the images are obtained by according to the measured geographical coordinate information of the control points and the aerial images by aerial triangulation, relative orientation and absolute orientation are conducted on all the images in an all-digital photogrammetry working station according to the obtained exterior orientation factors of all the images, a three-dimensional model is built, the topography and feature data collection is conducted in the built three-dimensional model, a digital surveying and mapping product is generated according to the collected topography and feature data, and the three-dimensional modeling and space analysis are conducted by using the generated digital surveying and mapping product based on the project application needs. The teaching efficiency can be improved, and the teaching effect can be improved.

Description

technical field [0001] The invention relates to surveying and mapping geographic information technology, in particular to a method and system for comprehensive teaching and training of photogrammetry and remote sensing. Background technique [0002] The surveying and mapping geographic information obtained by aerial photogrammetry technology is widely used in construction, planning, transportation, electric power, water conservancy, railway, agriculture and forestry, urban management, military, police, disaster reduction and relief and other industries. With its advantages of non-contact, high precision, high efficiency and high timeliness, aerial photogrammetry is playing an increasingly irreplaceable role in the construction of national geospatial infrastructure and data update. Aerial photogrammetry refers to the continuous photography of the predetermined ground by using the aerial photography equipment installed on the aircraft, combined with methods such as ground cont...

Problems solved by technology

[0004] However, at present, in the teaching of aerial photogrammetry and remote sensing professional courses in various colleges and universities, due to the need to use the aerial photography equipment installed on the aircraft to carry out large-scale field aerial photography, the cost is high, the amount of data is large, and the traffic conditions are limited. Aerial photography is not easy to achieve; at the same time, it also brings a lot of inconvenience to data processing and data application in the office

As a result, the data acquisition, data processing, and data application in the acquisition of surveying and mapping geographic information are independent of each other, and the teaching methods are not coherent and systematic. It is difficult to complete education and training tasks quickly, efficiently, comprehensively and systematically, resulting in low teaching efficiency and poor effect
