MRS system for documentation of the interiors of historical monuments by autonomous aerial vehicles has been deployed in the St. Moritz church in Olomouc. The drones can visit places which are not visible to the pilot as they fly autonomously, judging the environment using their onboard sensors and computer technology. They are able to take pictures from other angles than what is possible from the ground or a platform. For better pictures, a swarm of drones can be deployed with one drone carrying the camera and other drones carrying additional lightning. This project is carried out in cooperation with Národní památkový ústav (NPÚ) and supported by the Ministry of Culture of the Czech Republic. This project received wide coverage from the Czech media, for example, Seznam zprávy. Here is a link to video coverage.
