Problems solved by technology
[0003] However, at present, in the acquisition of aerial remote sensing data, the aerial photo quality inspection is usually carried out after the aerial photography is completed, and it is impossible to monitor the quality of the aerial photo in real time and make up the flight in time. Aerial photography of aircraft taking off and landing at the airport
And this will not only cause economic waste, but also cause time loss and increase security risks.

The invention relates to a method and a device for obtaining aerial remote sensing data. The method comprises the following steps: shooting targets and detecting shot aerial photos in real time to obtain quality evaluation information of the aerial photos; judging whether aerial shooting exposure points for shooting the targets need to be reset or not based on the quality evaluation information; and generating new aerial shooting exposure point position information in real time based on the quality evaluation information and environment information of the targets in case that the aerial shooting exposure points is determined need to be reset, feeding the position information back to flight control program for processing. Through the method and the device, the obtained aerial photos can bedetected in real time after obtaining the aerial photos; the quality evaluation information of the obtained aerial photos can be obtained; the higher-quality new aerial photos can be obtained by determining new aerial shooting exposure points in real time according to the quality evaluation information and shooting in time; in addition, the time cost and the economic cost can also be effectively reduced.
Description
technical field [0001] The present application relates to the technical field of photogrammetry, in particular to a method and device for acquiring aerial remote sensing data. Background technique [0002] Aerial photography refers to the method of photographing ground or air targets from the air by continuously taking pictures with aerial photography instruments on the plane. In the application, aerial photogrammetry can reduce the amount of field work, reduce labor intensity, and is not limited by geographical environment conditions, and has the advantages of fast, accurate and economical. At present, it is widely used in national major project construction, disaster emergency response and treatment, land supervision, resource development, new countryside and small town construction, etc., especially in basic surveying and mapping, land resource survey and monitoring, land use dynamic monitoring, digital city construction and emergency disaster relief. Surveying and mappi...
