COMPACT LASER AND GEOLOCATING TARGETING SYSTEM
A handheld targeting device that includes a geolocating system and a laser targeting system is provided. The geolocating system includes a laser range finder operable to emit a first pulsed laser beam toward an object from the first end of the housing and receive a returned first pulsed laser beam to calculate a distance to a target. By combining the calculated distance with a compass direction and position of the targeting device, a location of the object can be calculated. The laser targeting system includes a laser targeting marker operable to emit a second pulsed laser beam toward the object from the first end of the housing. Other vehicles or weapons can detect the second pulsed laser beam for indication of or guidance to the target. In one aspect, the laser range finder can share an optical lens with a thermal imager that captures infrared images.
Apparatus and method of measuring six degrees of freedom
A dimensional measuring device sends a beam of light to a remote probe having a retroreflector and a pitch/yaw sensor. The pitch/yaw sensor passes the light through an aperture and a lens to a position sensor that generates an electrical signal indicative of the position of the received light. A processor uses the electrical signal to determine a pitch angle and a yaw angle of the remote probe.
Redundant Reciprocal Tracking System
The present invention relates to a redundant reciprocal tracking system composed of at least two trackers 10. A first tracker is able to sense partial or full pose data (orientation and position) of a second tracker in a first reference frame and the second tracker is able to sense partial or full pose data of the first tracker in a second reference frame. Pose data of first and second trackers are further transferred to a central processor 30, which is able to compute the transformation between first and second reference frame. Data generated by the trackers are such designed that they define an over-determined mathematical system (e.g. more than 6 degrees of freedom in a 3D setup). The over-determined information can be used to qualify and/or improve the transformation of the reference frame. In an embodiment of the invention, the tracking system is an optical one and the over-determined information defines an error metric used to check the validity of the transformation. Such setup could be used in surgical navigation system in order to reduce the risk of injury or death of the patient.
System and method for augmented reality display of hoisting and rigging information
A method for providing information associated with a lift process to a mobile device user is presented. The method comprises receiving a request for lift environment information from a mobile device, determining a pose of the mobile interface device relative to a lift process target area, and obtaining lift environment information for at least a portion of the lift process target area. The lift environment information is used to assemble AR lift information for transmission to and display on the mobile interface device. The AR lift information is configured for viewing in conjunction with a real-time view of the lift process target area captured by the mobile interface device. The AR lift information is then transmitted to the mobile interface device for display.
MARKER FOR OPTICAL TRACKING, OPTICAL TRACKING SYSTEM, AND OPTICAL TRACKING METHOD
The present disclosure provides a marker with a pattern formed thereon, which includes an optical system. At least a part of the pattern that uniquely appears depending on a direction in which the pattern is viewed from an outside of the marker through the optical system, is visually identified from the outside of the marker. The pattern includes a plurality of rows of binary-coded sequences. The binary-coded sequence of each of the plurality of rows includes aperiodic sequences that are repeatedly arranged. The aperiodic sequences included in the binary-coded sequence of one row of the plurality of rows are different from the aperiodic sequences included in the binary-coded sequence of another row of the plurality of rows, and each of the aperiodic sequences includes a plurality of sub-sequences that are arranged in a predetermined order.
Systems and methods for determining optimal charging positions to maximize efficiency of power received from wirelessly delivered sound wave energy
The present disclosure describes a methodology for tracking position and orientation of one or more electronic devices, which may receive charge through wireless sound power transmission based on pocket-forming. This methodology may include one transmitter and at least one or more receivers, being the transmitter the source of energy and the receiver the device that is desired to charge or power. The transmitter may identify and locate the device to which the receiver is connected for subsequently charge and/or charge it. In order to increase charging and/or powering of electronic devices, a plurality of sensors may provide information determining the optimal position and/or orientation aimed to receive charge and/or power at the maximum available efficiency.
Image processing method, particularly used in a vision-based localization of a device
An image processing method includes the steps of providing at least one image of at least one object or part of the at least one object, and providing a coordinate system in relation to the image, providing at least one degree of freedom in the coordinate system or at least one sensor data in the coordinate system, and computing image data of the at least one image or at least one part of the at least one image constrained or aligned by the at least one degree of freedom or the at least one sensor data.
Methods and systems for identifying the user of a smartphone inside a moving vehicle and automatic detection and calculation of the time and location when and where a vehicle has been parked
Disclosed are systems and methods for identifying a user of a smart object inside a moving vehicle and as well as automatic detection and calculation of a time and a location when and where the vehicle has been parked. The systems and methods are capable to enable the identification of the user of an object inside a moving entity based on the orientation of the object to be localized as well as the movement direction of the moving entity.
Determining orientation
A luminaire is provided for use in determining an orientation of a camera based on an image of the luminaire captured by the camera. The luminaire comprises a light source having an on state in which it emits light and an off state in which it does not emit light, and being of a shape having a symmetry in the off state. The luminaire also comprises a controller configured to control the light source to emit said light in the on state with a lighting effect that breaks said symmetry. A device comprising receives an image of the light source from a camera, and determines an orientation of the camera relative to the light source by performing a geometric perspective calculation based on the image of the light source. An ambiguity in the orientation is resolved by detecting the asymmetry in the light emitted by the light source.
Indoor localization of a multi-antenna receiver
An approach to localization in an indoor environment makes use of a multiple antenna receiver (e.g., in a smartphone, tablet, camera) and knowledge of locations of one or more radio transmitters, which may be part of a data communication infrastructure providing data communication services to devices in the environment. Successive measurements of transmissions from the transmitters are recorded at the receiver as the device is translated and rotated in the environment. Rotation related measurements are also made at the device. The radio frequency and rotation related measurements are used to infer the location and orientation, together referred to as the pose, of the device. Phase synchronization of the transmitters and the receiver are not required. In general, accuracy of the pose estimate far exceeds that achievable using radio frequency measurements without taking into consideration motion of the device, and far exceeds that achievable using the inertial measurements alone.
