Fast photogRAmmetric voluMe EStimation

FRAMES (Fast photogRAmmetric voluMe EStimation) is an instrument designed for fully automated stockpile volume measurement using fast surface photogrammetry.

This method enables the generation of a three-dimensional reconstruction of the surface within minutes, based on the perspective differences captured from cameras placed at different positions.

FRAMES employs four fisheye cameras arranged apart from each other, each capable of capturing the entire surrounding environment where bulk materials are stored. These materials form irregular mounds on the ground.

After capturing images of the stockpile, they are processed using a photogrammetry algorithm that detects matching features across the different views. The algorithm then generates a 3D point cloud from which a surface model is built, allowing volume estimation of the stockpile.

The instrument is entirely solid-state, containing no moving parts, which enhances its durability and robustness. It is specifically designed to withstand harsh industrial environments, such as those with high levels of dust, humidity, or temperature fluctuations. Only the cameras are exposed, while all processing and communication components remain protected within an enclosed unit.
