REAL-TIME IMAGE DETECTION USING POLARIZATION DATA |
摘要 |
The present invention relates to a system and method of detecting polarized identification indicia in real-time. A frame of image data is provided having a plurality of pixels, wherein each pixel includes polarized light intensity information. An intensity value is determined for each of the pixels from the polarized light intensity information. A first portion of the pixels having intensity values within an intensity range is selected. The pixels in the first portion having similar angle of linear polarization values within a tolerance range are analyzed, thereby detecting the polarized identification indicia in the image data. |
