Multi-sensor compressive imaging

摘要

Multi-sensor compressive imaging systems can include an imaging component (such an RF, microwave, or mmW metamaterial surface antenna) and an auxiliary sensing component (such as an EO/IR sensor). In some approaches, the auxiliary sensing component includes a structured light sensor configured to identify the location or posture of an imaging target within a field of view of the imaging component. In some approaches, a reconstructed RF, microwave, or mmW image may be combined with a visual image of a region of interest to provide a multi-spectral representation of the region of interest.

1. A method, comprising:
identifying a region of interest within a field of view, wherein the identifying includes determining spatial information about a subject, the spatial information including a depth map characterizing a surface region of the subject, wherein the depth map defines a two-dimensional manifold corresponding to the surface region; illuminating the region of interest with one or more illumination field patterns; observing the illuminated region of interest with one or more measurement field patterns; and reconstructing an image of the region of interest using a compressive imaging algorithm, where the reconstructing depends on both the depth map and data from the observing.
