3D modeling clearly shows the entire picture of the site damage

"Objective -Sun Jiadong. Use the drone to carry out 3D reconstruction on the site of the ancient sites, and immediately draw a demonstration diagram of the on -site position." Recently, the police officer of the technical department of the Luanchuan County Procuratorate of Luanchuan County, Henan Province Nearby, use a special lens to use the drone, and cooperate with the intelligent drawing software to rebuild the landform near Sunjiadong. Subsequently, the clear on -site technical assistance reports and on -site orientation diagram were presented in front of the prosecutor.

The Sunjiadong site of Luanchuan County belongs to the precious old stone site and has been rated as the top ten archeological discoveries in the country. He was selected as a cultural relics protection unit in Henan Province. In October 2021, the police officer of the Luanchuan County Procuratorate found in a public interest lawsuit that the safety prevention facilities of the Sunjiadong site hole were simple and the environment was dirty. There were no signboards and warning signs. Subsequently, the hospital fixed relevant evidence with drones.

In February of this year, on the investigation, the Luanchuan County Procuratorate invited the county people's congress representatives, members of the CPPCC, as well as CPPCC members, and relevant departments of cultural tourism, environmental protection and other relevant departments to convene a hearing on the spot. Environmental cleanup and protection of facilities. After the hearing, the relevant functional departments immediately rectified and replied in writing the rectification situation in April.

A few months have passed, is the problem solved? A few days ago, the police of the public interest litigation department and the technical department of the hospital came to the Sunjiadong site again. Police officers took out the three -dimensional reconstruction of topography and landform maps, aerial photography pictures and on -site survey photos of the on -site case of drone technology were used to compare it. Green plant ... All the problems are in place.

"A variety of means such as UAV high -alternate, dynamic tracking, and detail capture make the evidence present more detailed and accurate, and effectively solves the problem of the difficulty of artificial investigation due to the limitation of objective conditions such as geographical location and surrounding environment. The handling of the case has played a good auxiliary role. "Pan Meng, director of the Procuratorate of Luanchuan County Procuratorate, introduced that in the past two years, the institute has established a clue investigation system for digital public interest litigation cases, exploring the function of orthogonal projection modeling, and using drones and intelligence. Drawing software is processed digital processing on the scene of the case, the situation of the scene is truly restored, and the calculation of data such as the area and volume of irregular target objects.

It is reported that since the institute has used drones to investigate evidence and obtain evidence in 2019, since the end of 2021, since exploring the 3D modeling function of the positive shot projection, as of now, drones have been used to carry out public interest proceedings to obtain evidence and obtain evidence and obtain evidence.
