摘要:
Methods and systems for inspection, safety assurance, tracking, and/or as-built comparison use an imaging tool to acquire imaging data of a scene. The imaging data is processed to create a three-dimensional representation of the scene. Radio frequency (RF) data is received from an RF tag using an RF reader. The RF tag is associated with an object within the scene. The object in the three-dimensional representation of the scene is identified based on the RF data and compared to a model of the object.

A moisture sensing watering system comprising a central pivot, a water conveyance system, a plurality of wheels, a first at least one moisture sensor coupled with a first wheel, a second at least one moisture sensor coupled with a second wheel, a moisture information converter, and a moisture content provider. The first moisture sensor pierces the ground during each rotation of the first wheel and performs a first moisture sensing as a part of the piercing of the ground. The second moisture sensor pierces the ground during each rotation of the second wheel and performs a second moisture sensing as a part of the second moisture sensor piercing the ground. The moisture information converter receives the moisture sensing information and converts the moisture sensing information into a signal. The moisture content provider provides the signal in a user accessible format.

A system, device and methods are provided for tracking objects, such as shipping containers and other movable items. In one embodiment, a method includes detecting an object based on detection of an object identification tag and detecting a marker during transport of the object, wherein detection of the marker includes determining location data of the marker. The method may further include storing position data for the object based on the location data of the marker, and outputting the position data for the object.

This application discloses a GNSS rover having a data receiver, a position processor and a vector error reverser. The data receiver receives GNSS position-determination reference data based on a reference erroneous position having one or more keyed intentional errors made confidential with confidential error keys. The position processor uses the GNSS position-determination reference data to determine a rover erroneous position corresponding to the reference erroneous position. The vector error reverser uses confidential access to at least one confidential error key to reverse the corresponding confidential keyed intentional error in the rover erroneous position to determine a subscribed rover position.

External accessory data is collected at a mobile data collection platform (MDCP) provided by an external accessory of the MDCP. An image that includes a point of interest is captured using an image capturing device integral to the MDCP. Raw observables are obtained from a GNSS chipset internal to the MDCP. An position fix of the MDCP defines the location of an antenna and is determined based on the raw observables. An entrance pupil location is calculated as an offset off the antenna location. Orientation information comprising a tilt angle and an azimuth angle is determined. The position fix and orientation information are associated with a three dimensional location that the MDCP is at when the image was captured. External accessory data is received from an accessory external to the MDCP. The image, position fix, orientation information and external accessory data are stored in hardware memory of the MDCP.

A known fixed relationship is maintained between an external electronic distance measurement accessory and a mobile data collection platform that are physically coupled together. A light beam axis of the external electronic distance measurement accessory is parallel with an optical axis of an entrance pupil of the mobile data collection platform. The external electronic distance measurement accessory integrates with the mobile data collection platform. The external electronic distance measurement accessory receives control instructions from the mobile data collection platform.

Efficient towed implement guidance to a desired path is achieved by guiding a towing vehicle toward a path on the opposite side of a desired path, then guiding the vehicle back to the desired path. Efficient forward implement guidance to a desired path is achieved by guiding a pushing vehicle along a tractrix. A vehicle leaves a straight line along a tractrix to keep a rear implement on the line as long as possible.

A radio frequency identification (RFID) tag distance measuring system and method is disclosed. One example includes a first replica path that receives a signal that is simultaneously transmitted to an RFID tag. The first replica path includes a plurality of taps at known distances along the first replica path. Each of the plurality of taps has a first tap input coupled with the first replica path. In addition, an RFID signal receiver receives a return signal from the RFID tag and provides the return signal along a measurement input, wherein each of the plurality of taps have a second tap input coupled with the measurement path. A distance determiner detects at least the first of the plurality of taps to have an output and determine a distance measurement to the RFID tag based thereon.
