Embodiment Construction

[0055] The basic idea of ​​the present invention is: using unmanned aerial vehicle technology, sensor technology, difference technology, aerial photography to generate high-resolution image technology, remote sensing interpretation application technology, GPS technology, etc. As a supplementary scientific operation method, conduct a high-precision, high-efficiency, and low-cost census of the target urban infrastructure to form a city infrastructure census result with strong current situation, high precision, and comprehensive data content.

[0056] Utilize above-mentioned thought to solve the census problem of urban infrastructure among the present invention Theoretical basis is:

[0057]UAV aerial photography system is a low-altitude aerial photography and mapping system. UAV flight technology can be used to fly at a height of 200-300 meters. The resolution is higher, and images with a resolution better than 0.05 meters can be shot. Advanced image processing software can prod...

Abstract

The invention discloses a method of carrying out an urban municipal general survey on the basis of an unmanned-aerial-vehicle low-altitude aerial-photography system. The method comprises the followingsteps: carrying out flight by an unmanned aerial vehicle to obtain images better than 0.05-m resolution; producing large-scale orthophotos; carrying out various types of infrastructure interpretationprocessing on the remote-sensing images by indoor work; producing working base graphs by indoor work; assisting supplementary detection and a survey of infrastructure attributes by outdoor work; andarranging urban infrastructure data by indoor work to form image data and vector data required for the infrastructure general-survey of a target city. An innovation point of the method is a job methodof taking image interpretation of indoor work as primary, and verification of outdoor work as supplementary, and the method changes data collection means of urban infrastructure general-surveys taking field surveying and mapping of outdoor work as primary in the prior art, saves a lot of manpower, material resources and time of outdoor work, and enables working efficiency of the urban infrastructure general-survey to be multiplied, survey costs to be reduced, and the survey method to be more scientific and reasonable.

Description

technical field [0001] The invention belongs to the technical field of aerial remote sensing image interpretation and processing, and in particular relates to a method for urban municipal census based on an unmanned aerial vehicle low-altitude aerial photographing system, which can be applied to urban infrastructure census. Background technique [0002] Urban infrastructure census, mainly through a comprehensive census of urban roads, bridges, street lighting, rivers, waters, sewage treatment, sanitation facilities, garbage disposal stations, green spaces, street trees, parks and other ancillary facilities , comprehensively grasp the basic situation of urban municipal utilities, landscaping, and environmental sanitation industry infrastructure, provide a basis for urban maintenance budgets, and provide basic data support for urban construction management decisions. [0003] The existing census method is mainly based on the outside industry, using dynamic GPS and other survey...
