  • Patent number: 10475203
    Abstract: Systems and methods are disclosed for measuring the dimensions of storage tanks using Optical Reference Line Method calibration techniques. The system utilizes a camera mounted near the tank wall such that its optical axis defines a reference line extending parallel to the wall and a robotic vehicle for moving a target object along the surface of the tank. Specifically, the target includes a predefined measurement scale that can be imaged by the camera as it is moved along the wall. A computer implementing computer-vision algorithms analyzes images of the scale captured at respective elevations to determine the point on the scale intersected by the reference line and a corresponding offset distance between the wall and the reference line. Accordingly, the dimensions of the tank are calculated by the computer based on the offset distance calculated for respective elevations of the tank wall.
