3. In case if there are two or more models ready, volume difference could be calculated for piles and ditches in a \"before\/after\" mode for the specified time period.<\/p> <\/div>\n<\/div>\n\n
\n
\n
If there is only one survey available, the volumes are calculated using the reference curface.<\/p> <\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n

The surveying is performed using industrial UAV in automatic mode under operator supervision. High quality of the obtained 3D model is achieved by using professional cameras (Sony RX-1) and precise synchronization of the shutter with GNSS receiver. <\/p> <\/div>\n<\/div>\n

The technology is based on the creation of a high-res 3D model of the quarry surface using UAV survey data and accurate GNSS measurements. Digital surface model built using unmanned aerial technologies is geometrically more accurate than one obtained using traditional on-the-ground methods.<\/p>\n<\/div>\n
Cost saving is achieved due to the high speed of data acquisition with the accuracy close to LiDar scanning. The costs of both field and desk work a reduced and the human factor is eliminated from calculations.<\/p> <\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n
