Abstract: Methods, apparatus, systems, and articles of manufacture to generate 3D point clouds based on spatiotemporal light patterns are disclosed. A controller includes processor circuitry to execute the instructions to generate a series of light patterns based on a set of light pattern tiles. Each of the light pattern tiles is defined by a different arrangement of illuminated pixels. Each of the light patterns is defined by a different arrangement of the light pattern tiles. The processor circuitry is to instruct a projector to project the series of light patterns; instruct an image sensor to capture a series of images of reflections of the series of light patterns; and generate a three-dimensional point cloud based on the series of captured images.
