Abstract : A method and system for an optical polling platform is provided. An optical polling server system receives an image of one or more augmented reality (AR) tag markers associated with a poll. Each AR tag marker is encoded with data, which includes at least a user identifier and a polling option. The system processes the image to identify the one or more AR tag markers in the captured image and detects edges in the image by traversing vertically along image columns. The system identifies potential AR tag markers from final edges based on contrast in pixels of the detected first set of edges and associated neighboring pixels. The AR tag markers are identified from the identified potential AR tag markers by sampling bit areas. Further, the system decodes the one or more AR tag markers to determine user identifier and polling option selected by the user identifier.
