航空摄影测量技术毕业设计
Introduction
Aerial photogrammetry is the process of taking photographs of the ground from an elevated position in order to obtain accurate measurements of terrain features. This technique has become increasingly popular due to the availability of unmanned aerial vehicles (UAVs) and the ease with which they can be equipped with high-resolution cameras. In this study, the focus is on the use of UAVs for aerial photogrammetry and the development of a custom-designed UAV system for accurate and efficient data acquisition.
Objectives
The main objective of the study is to design and develop a custom UAV system capable of acquiring high-quality aerial images for photogrammetric applications. The specific objectives are:
1. To review the principles of aerial photogrammetry and its applications in various fields
2. To identify the technical requirements and specifications for a custom UAV system
3. To design and build the UAV system, including the camera and other necessary components
4. To acquire aerial images using the UAV system and develop photogrammetric products such as point clouds and digital elevation models (DEMs)
5. To evaluate the accuracy and efficiency of the custom UAV system in comparison with other commercially available systems
Methodology
The methodology for this study involves a literature review of aerial photogrammetry principles and its applications in various fields. Technical requirements and specifications for a custom UAV system will be identified based on the literature review and consultation with experts in the field. The UAV system will be designed and built using off-the-shelf components, including a camera, GPS, and autopilot. A series of test flights will be conducted to evaluate the performance of the UAV system in terms of flight stability, image quality, and data accuracy. The acquired images will be processed using photogrammetric software to generate point clouds and DEMs. The accuracy and efficiency of the custom UAV system will be evaluated by comparing the results with those obtained from other commercially available systems.
Results
The results of this study will include the design and development of a custom UAV system for aerial photogrammetry, along with the acquisition of high-quality aerial images and photogrammetric products such as point clouds and DEMs. The accuracy and efficiency of the custom UAV system will be evaluated in comparison with other commercially available systems. The study will also provide insights into the potential applications of the custom UAV system in various fields, such as forestry, agriculture, and topographic mapping.
Conclusion
The use of UAVs for aerial photogrammetry has become increasingly popular due to their ease of use, affordability, and ability to acquire high-resolution images. This study aims to design and develop a custom UAV system for accurate and efficient data acquisition. The results of the study will contribute to the development of UAV-based photogrammetric applications in various fields, and provide useful insights into the potential of this technology for future research and development.。
