Computer implemented platform, software, and method for drawing using augmented reality

A non-transitory computer-readable medium storing a code with computer-readable instructions for drawing using augmented reality that when executed by a processor, causes the processor to execute a marker-less tracking algorithm stored in a memory of a mobile computing device to perform the steps of:

• detecting, by a page detector, an image of a drawing area;
• initializing a marker-less tracker, wherein said initializing comprises (a) capturing, via the page detector, a frame of the drawing area, (b) displaying, via a graphical user interface (GUI) of the mobile computing device, the frame of the drawing area, and (c) uniformly distributing on the GUI a template patch over the frame of the drawing area, wherein the template patch is a fragment of texture of a template image used for surface tracking;
• and
• executing a template patch tracking, wherein a perspective transformation of the template image to the frame as a current image is evaluated in video streaming on the GUI of the mobile computing device;
• wherein the processor is configured to detect a correspondence between one or more coordinates of the template image and one or more coordinates of the current image;
• and wherein the processor is configured to evaluate the perspective transformation based on the correspondence by random sample consensus (RANSAC);
• estimate a confidence level of the perspective transformation as a percentage based on the one or more coordinates of the current image having an under-threshold difference from one or more coordinates predicted by said evaluating the perspective transformation by RANSAC;
• switch, utilizing the percentage confidence level as a criterion to a re-initialization mode;
• update an initial template patch with an initial descriptor to an updated template patch with a new descriptor;
• monitor the updated template patch to validate it and responsive to a failure to validate the updated patch, switching back to the initial template patch with the initial descriptor;
• enhance the texture of the template image through template patches accumulation based on temporal averaging of binarized patches;
• and
• prepare a rough estimation of the perspective transformation by computing, via an inverse matrix, the perspective transformation from the template image to the current image.
