  • Patent number: 8379929
    Abstract: A method of determining an azimuth and elevation of a point in an image is provided. The method comprises positioning an imaging device at a first position and acquiring a first image. The method also comprises rotating the imaging device and acquiring a second image at the first position. The first image includes the point, and a portion of the first image overlaps a portion of the second image. The method also includes determining correspondences between features in overlapping portions of the images, determining a first transformation between coordinates of the first image and coordinates of the second image based on the correspondences, and determining a second transformation between the coordinates of the second image and a local coordinate frame. The method also includes computing the azimuth and elevation of the point based on the first transformation and the second transformation.

  • Patent number: 8368590
    Abstract: Methods and apparatus are provided for estimating parameters, i.e. ambiguities, derived from GNSS signals. Observations of GNSS signals are obtained from each of a plurality of GNSS satellites (120). The observations are fed to a filter having a state vector at least comprising a float ambiguity for each received frequency of the GNSS signals (140). The filter estimates float value for each float ambiguity of the state vector. Integer values are assigned to at least a subgroup of the estimated float values to define a plurality of integer ambiguity candidate sets (160). A first number of candidate sets is selected having a quality measure better than a first threshold, wherein the first threshold is determined based on a reference quality measure of a reference candidate set (180). A weighted average of the selected candidate sets is formed, each candidate set weighted in the weighted average based on its quality measure (200).

Observations of a GNSS signal from each of a plurality of GNSS satellites are obtained (2120). The observations are fed to a filter having a state vector comprising a float ambiguity for each received frequency of the GNSS signals (2140). The filter estimates a float value for each float ambiguity of the state vector and co-variance values associated with the state vector. Integer values are assigned to at least a subgroup of the estimated float values to define a plurality of integer ambiguity candidate sets (2160). A weighted average of the candidate sets is formed (2200). A formal precision value based on covariance values of the filter is determined (2205), the formal precision value being a measure for an achievable precision. An achieved precision value of the weighted average is determined (2210).

  • Publication number: 20130024245
    Abstract: In a computer implemented method for management of materials on a construction site, a status of a project which uses at least one material is determined by a computer system. A report is generated by the computer system. The report identifies a vehicle, from a vehicle pool, to be utilized to move the material and defines a load of the material which is to be moved by the vehicle, according to a mass haul plan, from a first location to a second location. The vehicle is identified based on results of a simulation. The status of the project is automatically updated by the computer system based on an actual size and an actual drop-off location of the load of the material moved by the vehicle. The computer system updates the report based on the updating of the status of the project.

  • Publication number: 20130002807
    Abstract: A method of measuring an angle includes orienting a measurement device at a reference position characterized by a reference angle. A first panoramic image defined by a predetermined range of elevation angles is acquired where the first panoramic image includes an object. A first bearing of the object in relation to the reference angle is determined and the measurement device is rotated to a measurement position characterized by a measurement angle. A second panoramic image defined by the predetermined range of elevation angles is acquired where the second panoramic image includes the object. A second bearing of the object in relation to the reference angle is determined. The measurement angle is computed as a function of the first bearing and the second bearing.

  • Patent number: 8330580
    Abstract: A radio device such as a wireless tag reader communicates with multiple types of wireless identification tags in a monitored region. The radio device includes a network interface to receive messages transmitted over a network. In response to receiving a message indicating to reconfigure the radio device to support an additional wireless tag protocol, the radio is reconfigured to support communications with a corresponding new type of wireless identification tag in a monitored region. Based on this technique of reconfiguring the radio device via network messages, the radio device optionally supports additional, new or latest versions of wireless tag protocols without having to physically reprogram or replace the radio device.

  • Patent number: 8319687
    Abstract: A system for determining the dimensional coordinates of a point of interest in a work space, includes a plurality of fixed-position ranging radios, located at known positions in the work space, and a wand having a first end configured for indicating a point of interest. A pair of ranging radios are mounted on the wand. A measurement circuit, responsive to the pair of ranging radios, determines the position of each of the pair of ranging radios with respect to the plurality of fixed-position ranging radios, and determines the position of the first end of the wand with respect to the plurality of fixed position ranging radios. A robotic total station may be used in lieu of the fixed-position ranging radios to monitor the positions of retroreflective elements on the wand.

  • Patent number: 8319950
    Abstract: A laser light receiver used to detect pulsed laser light that is produced by a rotating laser light source on a construction jobsite is disclosed. In this manner, the laser receiver acts as an elevation detector and provides an equipment operator, or a construction worker, with the current elevation status with respect to the plane of laser light. The laser receiver is a unitary device that can detect multiple light frequencies/wavelengths, including laser beams that are in the green, red, and infrared spectra. The laser receiver also is capable of discriminating between such laser beams and other interference light sources, particularly fluorescent light sources.
