Abstract: Example methods and systems for determining 3D scene geometry by projecting patterns of light onto a scene are provided. In an example method, a first projector may project a first random texture pattern having a first wavelength and a second projector may project a second random texture pattern having a second wavelength. A computing device may receive sensor data that is indicative of an environment as perceived from a first viewpoint of a first optical sensor and a second viewpoint of a second optical sensor. Based on the received sensor data, the computing device may determine corresponding features between sensor data associated with the first viewpoint and sensor data associated with the second viewpoint. And based on the determined corresponding features, the computing device may determine an output including a virtual representation of the environment that includes depth measurements indicative of distances to at least one object.

Abstract: A remote 3-D imaging system which uses a novel angular relationship to establish the relationship of the image features to the system, which is displayed by virtue of calculations. In addition to static surfaces, moving surfaces may be studied and corrections due to turbidity and platform position are also easily compensated for. A pre-test module is also included which predicts and has the ability to re-adjust the instrumentation to the test conditions as predicted by a hybrid Monte Carlo model. The instant system may also contain a plurality of sensing systems based on light, including traditional reflective or elastic scattering and novel fluorescent or non elastic scattering still and video imaging systems, including time-gated systems.

Abstract: A three-dimensional light beam acquisition apparatus includes an imaging optical system and an illumination optical system. The imaging optical system includes a first optical element that allows to pass through light from a subject; a second optical element that is arranged on the optical axis of the first optical element, receives the light from the first optical element, and forms an image corresponding to received light; and an acquiring unit that acquires the image from the second optical element as light beam information. The illumination optical system includes a light source; and a third optical element that collects illumination light from the light source and irradiates the subject with the illumination light through the first optical element.
