Abstract: Researchers are interested in studying technology. Photo aerial photography Survey of unmanned aerial photography The purpose is to bring the model data acquired to the construction plan. And use the benefits. In the next construction project No need to access the survey area. To maintain operating costs. And work time Surveying uses aerial photo data. With the Mavic Pro DJI's multi-mode aerial, the Autopilot has a 12-megapixel camera. The photos are processed using the Pix4D program, which surveys the elevation at a height of 30 meters. 60 meters and 90 meters meters to compare models at each altitude of flight. And to compare the altitude information of the flight. With the traditional survey method. The results of the research study found that A visual survey of UAV unmanned aerial vehicles at different altitudes was as follows: Compare with ground survey work with theodolite. The mean error was 0.56 %, which was in the confidence interval of 99 %, less than the significance level, less than 0.01. The model was used in the construction project at an altitude of 60 meters and 90 meters compared to the ground survey. The mean error was 1.03 % and 1.19, respectively, which was out of the 99 % confidence interval, less than the significance level of 0.01. It is not possible to use the data from the results and the combined form in the construction project. That is, from the flight collecting photos in the construction site that the researchers studied. At a distance of 30 meters, it is a suitable level that can be used for further construction.
