Abstract:
A system and method for determining depth information of an object is provided. The system projects dots on an object and captures an image of the object with captured dots. The system identifies the captured dots based on a brightness of the captured dots and identifies coordinates of the captured dots. The system processes the captured image by removing brightness information of pixels outside of the captured dots. The system processes the captured dot by overlaying synthesized dot image on the captured dot. The system divides the processed captured image into captured sections and compares the captured sections to reference sections. The system selects individual reference sections having a highest correlation score for each of the captured sections and correlates a captured dot from each of the captured sections to a reference dot in respective corresponding reference sections. Depth information may be calculated based on coordinates of the captured dots and correlated reference dots.
