Embodiment 1

[0035] UAV audio measurement method, such as figure 1 As shown, including the following steps:

[0036] S1: Site Measurement Determination: Arrival at the scene, identify the range of measurement regions, and analyze the measurement area satellite map;

[0037] S2: Judgment weather conditions: Observe the measurement weather, select cloudy weather or high brightness, and the illumination should increase the exposure time, the ISO value low represents the quality of the imaging, and the site wind speed, the ground four-stage wind and the ground Suitable, anti-wind, wind, temperature 0 ° C -40 ° C, temperature too high or too low affect battery stability and camera accuracy, and record information such as wind speed, weather, take-off and landing coordinates, check the date of data reference and analysis to sum up;

[0038] S3: Equipment Test: The remote control is inserted into the 4G network card, and the SIM card installation check, the CORS connection signal check, and check the...

Abstract

The invention discloses an unmanned aerial vehicle aerial photography measurement method and system, and relates to the technical field of unmanned aerial vehicle aerial photography measurement. The problem of ensuring the aerial photography effect of the unmanned aerial vehicle is solved. The method specifically comprises the following steps: field measurement determination: arriving at a field, identifying a measurement area range, and analyzing a satellite map of the measurement area; judging weather conditions: observing measurement weather, selecting cloudy weather or high-brightness cloudy days, increasing exposure time if illumination is poor, wherein imaging quality is good if an iso numerical value is low, and measuring field wind speed, wherein ground four-level wind and below are suitable, the unmanned aerial vehicle takes off when being against the wind and returns when following the wind, the temperature is 0-40 DEG C, the battery stability and the camera precision are influenced when the temperature is too high or too low; and reocrding information such as wind speed, weather and take-off and landing coordinates of the day. According to the invention, an image with high resolution can be obtained and is basically not interfered by a cloud layer, meanwhile, the height formed with the ground is freely controlled, and the obtained image data is more detailed and has high resolution.

Description

Technical field [0001] The present invention relates to the field of drone aerial photographic measurement, in particular, relates to a method of disconnecting an aircraft aerial test and its system. Background technique [0002] With the booming of drone aerial technology, conventional aviation photogrammetry of poor timeliness and high cost is replaced. At present, the drone aerobics is not only longitudinally extending in the field of agriculture, forestry, water conservancy and transportation; in the field of surveying and mapping, especially engineering measurement, road measurement, power transmission line measurement in routine earthwork engineering The feasibility study, the preliminary application has gradually reflected its superiority and convenience. [0003] After the search, the Chinese patent application number is a patent of CN201210037780.8, which discloses an automatic audio-visual measurement method and a drone aerial test system, which can obtain accurate airp...
