Abstract
Systems of this disclosure enable building inspection using polarization images. The systems use light polarization information of the polarization images to detect misapplications of tape applied to a substrate. An example system includes polarization camera hardware, a memory communicatively coupled to the polarization camera hardware, and processing circuitry communicatively coupled to the memory. The polarization camera hardware is configured to capture a polarization image of a tape as applied to a substrate. The memory is configured to store the polarization image. The processing circuitry is configured to analyze the polarization image according to a trained classification model and, based on the analysis of the polarization image according to the trained classification model, detect a misapplication with respect to the tape as applied to the substrate.
