Abstract

Systems and methods are provided for rendering graphics in augmented reality software based on the movement of a device in relation to a target object, in order to produce more desired rendering effects. An augmented reality graphic can be both scaled and shifted laterally compared to the target based on a position of the device, and can then be cropped to match the target. Scaling and shifting related to movement parallel to the target can be performed using a first (parallel) function, and scaling and shifting related to movement toward and away from the target can be performed using a second (perpendicular) function. Both functions can be chosen to ensure that an edge of the augmented image is not passed over so as to provide blank space.

Claims20

Dependent claims

A mobile device comprising:

one or more processors;
a screen;
a camera communicatively coupled to at least one of the processors;
and
a non-transitory computer-readable medium comprising code, executable by at least one of the processors, to implement a method for augmenting a video feed displayed on the screen of the mobile device, the method comprising:
receiving a live video feed taken by the camera, the live video feed including a target object;
receiving a graphic corresponding to the target object, the graphic having boundaries;
determining a magnitude and a direction of a lateral offset vector of the mobile device, the lateral offset vector being a measurement of a distance from the center of the target object to the mobile device in a direction parallel to a plane of the target object;
determining, based on the magnitude of the lateral offset vector, a shift magnitude;
determining, based on the direction of the lateral offset vector, a shift direction, wherein the shift direction is opposite the direction of the lateral offset vector;
determining a display position, wherein the display position is a position on the graphic, and wherein the display position is separated from a center point on the graphic by the shift magnitude in the shift direction;
determining a portion of the graphic to be displayed, wherein the portion is located at the display position, wherein the portion has an edge that asymptotically approaches a boundary of the graphic as the absolute value of the lateral offset vector increases;
and
displaying, on the screen, the portion of the graphic over at least a portion of the target object.
