摘要: A system simultaneously tracks multiple objects. All or a subset of the objects includes a wireless receiver and a transmitter for providing an output. The system includes one or more wireless transmitters that send commands to the wireless receivers of the multiple objects instructing different subsets of the multiple objects to output (via their respective transmitter) at different times. The system also includes object sensors that receive output from the transmitters of the multiple objects and a computer system in communication with the object sensors. The computer system calculates locations of the multiple objects based on the sensed output from the multiple objects.

摘要: Methods and systems are provided, which illuminate a scene with pulsed patterned light having one or more spatial patterns; detect reflections of the pulsed patterned light from one or more depth ranges in the scene, by activating a detector for detecting the reflections only after respective traveling times of the illumination pulses, which correspond to the depth ranges, have elapsed; and derive an image of the scene from the detected reflections and according to the spatial patterns. The methods and systems integrate gated imaging and structured light synergistically to provide required images which are differentiated with respect to object ranges in the scene and different patterns applied with respect to the objects and their ranges.

摘要: A distance camera includes at least one photo element, a trigger generator activating the photo element during a temporal integration gate, a light source illuminating an object with light pulses having a predetermined temporal intensity profile with a duration Tp, and an intensity sensor determining the intensity Ip of the light pulses arriving on the photo element. The integration gate has a predetermined delay to the light pulse emission start point in order to capture the light pulses back reflected from the object. The photo element outputs a signal value U at an integration end point in time T1e and in accordance with an intensity Ip and a duration of the light pulse arriving on the photo element during its activation.

摘要: A gated time of flight (GT-TOF) range camera that transmits a plurality of light pulses to illuminate features in a scene and gates ON a photosensor in the camera for one multi-exposure gate having a plurality of exposure periods following each of the plurality of light pulses to register amounts of light reflected by features in the scene from the light pulses and uses the registered amounts of light to determine distances to the features.

摘要: A GT-TOF camera that illuminates a scene with a train of light pulses to determine amounts of light reflected from the transmitted light pulses by features in a scene for each of N different exposure periods and determines a distance to a feature in the scene responsive to a direction in an N-dimensional space of an N-dimensional vector defined by the amounts of reflected light determined for the feature for the N gates.

摘要: An apparatus for the imaging of gaseous fluid motion is disclosed. The apparatus includes a sub-nanosecond pulsed laser. The sub-nanosecond pulsed laser is configured to cause a particle species to fragment and for the recombining fragments subsequently to fluoresce. The apparatus also includes a gaseous fluid comprised of particle species. The apparatus also includes a time gated camera. The time gated camera configured to capture at least one image of the fluorescence from the recombining particle fragment species displaced after a specific time lapse following the laser pulse. Additionally, a fluid velocity can be calculated from a comparison of the image of the displaced particle species to an initial reference position and the time lapse. A Femtosecond Laser Electronic Excitation Tagging (FLEET) method of using the disclosed apparatus is also disclosed.

摘要: Systems and method for imaging through scattering media. One example of an imaging system includes an illuminator configured to produce a structured illumination pattern and to direct the structured illumination pattern into an imaging field through a scattering medium, a camera configured to receive reflections of the structured illumination pattern from an object in the imaging field and to provide corresponding image data, a master oscillator coupled to the illuminator and to the camera and configured to modulate the structured illumination pattern and to clock the camera so as to time gate the reflections of the structured illumination pattern and provide signal timing data, and a processor coupled to the camera and received to receive and process the image data and the signal timing data to produce an image of the object.

摘要: Active-gated imaging system and method for imaging environment with at least one high-intensity source. A light source emits light pulses toward the environment, and an image sensor with a pixelated sensor array receives reflected pulses from a selected depth of field and generates a main image. The image sensor exposure mechanism includes a pixelated transfer gate synchronized with the emitted pulses. An image processor identifies oversaturated image portions of the main image resulting from a respective high-intensity source, and interprets the oversaturated image portions using supplementary image information acquired by image sensor. The supplementary information may be obtained from: a low-illumination secondary image having substantially fewer gating cycles than the main image; by accumulating reflected pulses from the high-intensity source after the reflected pulses undergo internal reflections between optical elements of the camera; or a low-illumination secondary image acquired by residual photon accumulation during a non-exposure state of image sensor.

摘要: A system and a method for object selective camera flash are provided herein. The steps of the method may include: capturing a raw image of a scene using a capturing device, wherein a scene comprises background and objects viewed by the capturing device; indicating at least one location on the captured raw image, wherein the location on the captured image corresponds with a location in the scene; calculating a volume portion within the scene based on the indicated at least one location on the captured raw image; generating a flash pulse having specified parameters directed at the scene; synchronizing an exposure of the capturing device to be carried out when reflections of the flash pulse from the calculated volume portion reaches the capturing device; and accumulating the reflections to yield an enhanced image.

摘要: A method and a system for inertial measurement. The method includes controlling at least one imaging sensor to capture at least two consecutive images, processing the at least two consecutive images to identify at least one feature therein and determining at least one parameter associated with the at least one feature, and determining a change in a position and an orientation of the at least one imaging sensor, based upon the at least one parameter associated with the at least one feature. The at least one parameter includes at least one of: a presence or absence of the at least one feature in at least one of the at least two consecutive images, respective pixel locations of the at least one feature in the at least two consecutive images, and/or three-dimensional locations of the at least one feature with respect to the at least one imaging sensor.
