    摘要: An exemplary depth capture system (system) emits, from a first fixed position with respect to a real-world scene and within a first frequency band, a first structured light pattern onto surfaces of objects included in a real-world scene. The system also emits, from a second fixed position with respect to the real-world scene and within a second frequency band, a second structured light pattern onto the surfaces of the objects. The system detects the first and second structured light patterns using one or more optical sensors by way of first and second optical filters, respectively. The first and second optical filters are each configured to only pass one of the structured light patterns and to block the other. Based on the detection of the structured light patterns, the system generates depth data representative of the surfaces of the objects included in the real-world scene.

    摘要: Scanning apparatus (20, 80) includes a base (22, 82) and a gimbal (52), including a shaft (56) that fits into rotational bearings (58) in the base and is configured to rotate through 360O about a gimbal axis relative to the base. A mirror assembly (60), fixed to the gimbal, includes a mirror (50), which is positioned on the gimbal axis and is configured to rotate about a mirror axis perpendicular to the gimbal axis. A transmitter (40) directs pulses of optical radiation toward the mirror, which directs the optical radiation toward a scene. A receiver (66) receives, via the mirror, the optical radiation reflected from the scene and outputs signals in response to the received radiation. Control circuitry (34) drives the gimbal to rotate about the gimbal axis and the mirror to rotate about the mirror axis, and processes the signals output by the receiver in order to generate a three-dimensional map of the scanned area.

    摘要: A system includes a first scanner having an inflatable membrane configured to be inflated with a medium to conform an exterior surface of the inflatable membrane to an interior shape of a cavity. The medium attenuates, at first rate per unit length, light having a first optical wavelength, and attenuates, at a second rate per unit length, light having a second optical wavelength. An emitter is configured to generate light to illuminate the interior surface and a detector is configured to receive light from the interior surface. The scanner further includes a processor configured to generate a first electronic representation of the interior shape based on the light. A design computer is configured to modify the first electronic representation into a three-dimensional shape corresponding to at least a portion of the interior shape and a fabricator configured to fabricate, based at least on the modified first electronic representation, an earbud.

    摘要: Technologies are generally described for calibrating three-dimensional image sensors. In some examples, an imaging system may include a sensor for detecting two-dimensional image data associated with a scene and a sensor for detecting depth data associated with the scene. Both sensors may also be configured to detect a reference signal used to illuminate the scene. The imaging system may then be configured to form three-dimensional data about the scene by using the reference signal to combine the two-dimensional image data and the depth data.
