Pix4D, an aerial-image processing software provider, has enlisted the help of unmanned aerial systems (UAS) to let you explore what it calls ‘Switzerland's most visited historic monument’ – but without the hefty travel expenses.
According to the company's project outline and YouTube video, Pix4D wanted to create a “highly accurate” and “very dense” three-dimensional model of the Chateau de Chillon, or Chillon Castle, on Lake Geneva in the City of Veytaux.
In only four hours, the company says, it collected more than 6,200 indoor and outdoor photos of the vast structure by using a quadrocopter equipped with the GoPro camera, the DJI Phantom 2 Vision and the sensefly eBee, and several cameras not on drones.
It then used the Pix4Dmapper technology to convert the photos into 3D point cloud, comprising 95 million points and 19 different data sets. The result is a lifelike, virtual map of the castle, with accuracy between 5 mm and 20 cm, the company says.
