Abstract: A method and system for camera calibration comprises configuring a calibration target comprising calibration reflectors on a test vehicle. Video of a test scene is collected. Next the test vehicle is identified as it enters the test scene and recorded as it passes through the test scene. The position of the calibration target in each frame of the video is determined and the corresponding individual position of each calibration reflector for each frame of the recorded frames is used to construct a camera calibration map to calibrate the video camera.

Abstract: A system for capturing live-action three-dimensional video is disclosed. The system includes pairs of stereo cameras and a LIDAR for generating stereo images and three-dimensional LIDAR data from which three-dimensional data may be derived.

Abstract: Fouling of or damage to an electromagnetic radiation-transparent window can preclude one from obtaining satisfactory images with an image acquisition unit, such as a camera. Certain types of environments may be particularly prone toward promoting fouling or damage, and manual cleaning or repair of an electromagnetic radiation-transparent window may be difficult in some circumstances. These issues may be particularly prevalent when imaging drill cuttings and other solids obtained from a wellbore due to the complex sampling environment in which these solids are often disposed.
