In response to these issues, Takenaka Corporation, together with Kanamoto and Aktio, conducted a demonstration test of indoor and outdoor autonomous flight using BIM for automatic flight of drones, and confirmed the effectiveness of ensuring the accuracy required for autonomous flight. This is a technology that uses Visual SLAM technology and BIM with a stereo camera mounted on the drone to make the drone fly stably even in a building where GNSS radio waves do not enter.
Until now, efforts to fly drones in indoor spaces where GNSS radio waves do not enter using Visual SLAM technology have been carried out by drone makers and solution providers. However, when Visual SLAM acquires the surrounding environment for about 10 minutes when the drone flies, an error "drift" with the actual environment gradually occurs. The error between this actual environment and the 3D space obtained by Visual SLAM will cause the drone to deviate from the specified position.
Therefore, in the indoor / outdoor autonomous flight system "BIM x Drone" of Takenaka Komuten, Kanamoto, and Aktio, BIM data is used as a map of this three-dimensional space, and it is corrected by collating with the data of Visual SLAM. , Achieves more accurate drone flight.
