摘要： A calibration device and method of calculating a global multi-degree of freedom (MDF) pose of a camera affixed to a structure is disclosed. The method may comprise: determining, via a computer of a calibration device, a calibration device MDF pose with respect to a global coordinate system corresponding to the structure; receiving, from an image system including the camera, a camera MDF pose with respect to the calibration device, wherein a computer of the image system determines the camera MDF pose based on an image captured by the camera including at least a calibration board affixed to the calibration device; calculating the global MDF pose based on the calibration device MDF pose and the MDF pose; and transmitting the global MDF pose to the image system such that a computer of the image system can use the global MDF pose for calibration purposes.

摘要： This disclosure, and the exemplary embodiments provided herein, include a system and method for encoding information in a relatively dense and time-varying manner. In exemplary embodiments, a reflector or retroreflector is wrapped around a rotating member, such as a cylinder, (also referred to as “Rotational LIDAR Barcodes”), which encodes relatively longer data messages, as compared to a static barcode, which can be detected by a LIDAR system and decoded from every direction, i.e. bearings angles of 0-360 degrees, even when partially obstructed.

摘要： A system includes a series of converters provided along a boundary of an agricultural cultivated area. A converter is configured to emit a second signal in response to an incoming first signal. The system also includes an autonomously driving agricultural machine including a transmitting device configured to emit the first signal in an environment of the agricultural machine, a receiving device configured to receive the second signal emitted in response to the first signal, and a processing device configured to determine a position of the agricultural machine with respect to the boundary based on the received second signal. An arrangement and/or a conversion characteristic of converters is designed differently at a first section of the boundary than at a second section of the boundary.

摘要： Described herein are methods and devices for improved location of any and all underwater structures or equipment installed underwater. In particular, systems are disclosed that combine optical and acoustic metrology for locating objects in underwater environments. The systems allow for relative positions of objects to be determined with great accuracy using optical techniques, and support enhanced location of devices that utilize acoustic location techniques. In addition, location information can be provided by the system even in conditions that make optical metrology techniques impossible or impractical.

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： A system for enhanced object detection and identification is disclosed. The system provides new capabilities in object detection and identification. The system can be used with a variety of vehicles, such as autonomous cars, human-driven motor vehicles, robots, drones, and aircraft and can detect objects in adverse operating conditions such as heavy rain, snow, or sun glare. Enhanced object detection can also be used to detect objects in the environment around a stationary object. Additionally, such systems can rapidly identify and classify objects based on the encoded information in the emitted or reflected signals from the materials.

摘要： A system for remotely sensing light from within a monitored environment containing one or more retro-reflective optical elements. The system includes an illuminator including a light source and a reflector unit comprising a deformable mirror arranged to receive light from the light source and to reflect the received light. This outputs illumination light from the illuminator for illuminating the optical element(s) within the monitored environment. A detector is arranged to receive light returned by the one or more retro-reflective optical elements in response to the illumination light. The detector determines a wavefront of the returned light and detects a property of the monitored environment according to the returned light. The reflector unit is arranged to deform the deformable mirror according to the determined wavefront such that light from the light source is reflected by the deformable mirror so deformed to output illumination light with a modified wavefront.

摘要： An Identification Friend or Foe (IFF) interrogation system and method adapted for: transmitting RF broadcast signal to be received by complementary transponder(s) of the IFF system being within the interrogation range and thereby arm the complementary transponders for sensing laser beam illumination; receiving an RF response signal from the complementary transponder(s); operating a laser activation interface module, which is configured for interfacing an external laser transmitter, to determine activation of transmission of an interrogating laser beam by the external laser transmitted; and receiving and processing RF signals to identify therein RF response signal(s), which are transmitted by the complementary IFF transponder(s) in response to detection of the trans mitted laser beam. In some implementations the complementary transponder is configured to encode, in the RF response signal, an identification code of the interrogator in the form of data indicative of a time pattern representing time interval(s) between the transmissions of the RF broadcast signal and the interrogating laser beam. In turn, the interrogation system may be adapted to decode the identification code from the RF response signal and thereby determine whether the RF response signal is addressed thereto. In some cases where the laser beam of the external laser transmitter has a cross-sectional area smaller than the interrogation region, there is further provided a beam scattering directive providing instructions for directing the optical axis of the external laser transmitter to wards light scattering surfaces in the vicinity of the interrogation region so it is illuminated by scattering of the laser beam by the scattering surfaces.
