Application of INSPIRE PRO drone aerial shot in Jianglang mountain three-dimensional reconstruction of world heritage

World Heritage is one of the most precious parts of social public resources, which is universally recognized as a cultural relic and natural heritage with prominent significance and universal value. World Heritage has been listed as "National Public welfare undertakings" by all countries. The function and nature of world heritage determines that it must be administered by the government. The precise protection of world heritage is that it can be preserved with the most world heritage of data and imagery. It is accurately restored to facilitate the analysis and further protection of the World heritage by scientific research units and historical units.

The traditional data extraction is a kind of scenic spot where the researchers take the material from the camera and extract the objects generally. Usually there is a small range of materials, the data can be analyzed is not comprehensive. Do not have a comprehensive analysis and protection of the world heritage. So what kind of collection method to take, this is the World Heritage protection organization urgently need to solve the problem.

In mid-December 2015, Shanghai Bo Radium Intelligent Technology Co., Ltd. (hereinafter referred to as Bo Radium) United Jiangshan Land and Resources Bureau and Jiangshan Tourist bureau, Zhejiang province, the first world natural heritage-Jianglang mountain three-dimensional re-modeling, will Jianglang mountain to three-dimensional image data collection and preservation. Make a significant contribution to future research and protection.

This project uses Shenzhen DJI UAV's product "Wu PRO", with X5 high-definition camera to Jianglang mountain all-round surround shooting.

6 o'clock in the morning, Jianglang Mountain Action Team has arrived at the best shooting location-sky Ping. But the mountain high altitude, plus Jianglang Mountain Special geographical environment, cloud time scattered. Bo Radium's flight Control Hand and image engineer can only take advantage of each cloud to disperse 20 minutes, seize the time to carry out three-dimensional reconstruction material collection.

This three-dimensional reconstruction action is a major difficulty is to Jianglang mountain the first day of filming, Jianglang Mountain Line Day is high 312 meters, 298 meters long, the widest place 4 meters, the narrowest place 3.5 meters, experts assigned as "the first day of the country." This is very demanding for our aircraft control hands.

Bo Radium Engineers after a day of multiple transitions, finally completed the Jianglang Mountain three-dimensional reconstruction of the material extraction. Enter the next step in the industry processing. The extracted material is refined to eliminate the defective item. Three-dimensional modeling of useful footage.

After a professional review, the useful material is added to the background processing software pix4d for three-dimensional reconstruction.

After the work of Bo radium internal and external engineers of the tireless efforts and meticulous working. The final Jianglang mountain model can be perfectly presented in front of us. This is of great significance to the analysis and protection of the world Natural heritage.
