SYSTEM AND METHOD FOR THREE-DIMENSIONAL REPRODUCTION OF CLOUD OF COLOURED POINTS FOR PURPOSES OF MINING Russian patent published in 2025 - IPC G01C21/16 G01S17/86 G06T17/00 G06T5/80 

FIELD: physics.

SUBSTANCE: invention relates to three-dimensional reproduction of coal mines. Disclosed is a system and a method for three-dimensional reproduction of a cloud of coloured points for purposes of mining. System includes: first multi-frequency laser radar (1), second multi-frequency laser radar (2), laser radar holder (3), panoramic camera (4), inertial navigation device (6) and data processing computer (7). First multi-frequency laser radar (1) is mounted on laser radar holder (3) and is oriented in a horizontal position. Second multi-frequency laser radar (2) is installed on laser radar holder (3). Orientation directions of the second multifrequency laser radar and first multifrequency laser radar (1) form a right angle. Panoramic camera (4) is located above the first multi-frequency laser radar (1), inertial navigation device (6) is located under laser radar holder (3), and computer (7) for data processing is located under holder (3) of laser radars. RGB information is added to the point cloud when constructing the point cloud and the problem associated with the complexity of recognizing objects at the coal mine face is solved.

EFFECT: high accuracy of the created image in relation to the real image.
