Augmented reality digital content search and sizing techniques

A method implemented by a computing device, the method comprising:

• displaying, by a display device of the computing device, a digital image of an object;
• determining, by the computing device, dimensions of the object in the digital image;
• selecting, by the computing device, a three-dimensional geometric shape that approximates a boundary of the object based on the determined dimensions of the object in the digital image, the selected three-dimensional geometric shape selected from a plurality of three-dimensional geometric shapes that are predefined;
• capturing, by the computing device, a live stream of digital images from a digital camera of a physical environment;
• and
• displaying, by the display device of the computing device, the selected three-dimensional geometric shape as augmented reality digital content based on the determined dimensions as part of the live stream of digital images.

A system comprising:

• a dimension determination module implemented at least partially in hardware of a computing device to determine dimensions of an object included in a two-dimensional digital image;
• a shape selection module implemented at least partially in hardware of the computing device to select a three-dimensional geometric shape that approximates a boundary of the object based on the determined dimensions of the object in the two-dimensional digital image, the selected three-dimensional geometric shape selected from a plurality of three-dimensional geometric shapes that are predefined;
• a digital camera configured to capture a live stream of digital images of a physical environment, in which, the digital camera is disposed;
• and
• an augmented reality rendering module implemented at least partially in hardware of the computing device to render, by a display device, the selected three-dimensional geometric shape, independent of the object, as augmented reality digital content based on the determined dimensions as part of the live stream of digital images.
