Quarry monitoring
Earthworks volume calculation and control of the compliance with the project design
Aerostream offers a service for open mine and quarries change detection. We use innovative UAV technologies and the latest advances in data processing and computer vision.
We offer
- Quarries, dumps, excavations and piles 3D modelling
Horizontal and vertical accuracy of the model - 5 cm. Digital terrain model and a high resolution orthomosaic produced along with the 3D model. - Volume calculation for piles, excavations and dumps
Technology allows getting the accurate volume calculations just in few hours after the flight. Obtained data could be then published in the WEB viewing service. - Volume difference calculation
During periodic monitoring we can calculate volume difference of any pile or ditch in "before/after" mode for each the specified time period. - Publishing data online
Monitoring data publishing on the web service. Creating the 3D model of the quarry on a cartographic basis, with the output of indicators of volume changes for the selected period of time - Real-time aerial monitoring
With image transmission in HD quality.
Examples of quarry surveying and 3D modeling
How it works:
1. Regular periodical surveying
2. 3D quarry model produced for each survey
Horizontal and vertical accuracy of the model - 5 cm. Digital terrain model and a high resolution orthomosaic produced along with the 3D model.
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.
If there is only one survey available, the volumes are calculated using the reference curface.
4. Data could be published in a WEB-service as a set of layers, each representing a survey. You can share it using a private link and view from any workstation.
We use professional industrial drones
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.
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.
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.
