Abstract
A method and system for automated visual analysis of a dipstick using standard user equipment (UE) are disclosed herein. The method may include the following steps: capturing, using an arbitrary UE having specified image capturing and processing capabilities, an image of a dipstick having colored test reagents, and a calibration array having a plurality of colored calibration elements which are tailored specifically to the test reagents; deriving, based on the captured image, illumination parameters associated with the dipstick and the calibration array; determining whether the illumination parameters are within predefined illumination boundary conditions sufficient for interpreting the test reagents, given the specified image capturing and processing capabilities of the UE; applying image enhancement operations to the captured image, based on predefined mapping between the derived illumination parameters and the required adjustments; and interpreting the colored test reagents, based on the colored calibration elements, in the enhanced captured image.
