Abstract
A system includes a sensor including a set of cameras configured to capture a set of images of an enclosed space. The system further includes a processor and a non-transitory computer-readable medium containing instructions which, when executed on the processor, cause the processor to perform operations including: (a) receiving the set of images captured by the set of cameras; (b) pre-processing the set of images to increase quality and reduce effect of ambient lighting; (c) building a disparity map for the set of images based at least in part on a relationship between the set of cameras; and (d) determining an occupancy of the enclosed space based at least in part on the disparity map. The system can be used to determine occupancy in a trailer with irregularly shaped cargo using low cost sensors.
