Abstract:
Spaced-apart light spots are projected in a light pattern on a target surface lying in a target plane. A range spot is projected at a position on the target surface to find a target distance to the target surface. An image of the target surface, light pattern, and range spot is captured along an imaging axis that is perpendicular to an imager plane of an imager. A controller determines an angular relationship between the imager and target planes based on the light pattern in the captured image, determines a scale relationship between the target surface and the imager based on the position of the range spot in the captured image, displays a compensated image of the target surface that is corrected in tilt by the angular relationship and in scale by the scale relationship, and determines dimensions of the target surface based on dimensions of the displayed compensated image.
Abstract:
A method, computer program product, and system of stitching aerial data using information from at least one previous image are disclosed, the method includes: capturing a plurality of images of the landscape and storing the plurality of images with image metadata, the image metadata including at least one or more of the following parameters: latitude and longitude, altitude, pitch angle, roll angle, and yaw angles; generating a set of transformed images based on the image metadata, wherein generating the set of transformed images based on the image metadata comprises: setting a variable for each of the parameters; and calculating quality of fit for each of the plurality of images; normalizing the plurality of captured images using the set of transformed images; and assembling a new aerial image based on the plurality of captured images by fitting the plurality of normalized captured images to a top level image.
Abstract:
Stockpile reconciliation is disclosed. Overhead imagery of a pile is accessed at a first point in time. At least one dimension of the pile is determined based on the overhead imagery of the pile. An operational characteristic associated with a generation of the pile is accessed. A three-dimensional (3D) model of the pile is generated based on the at least one dimension of the pile and the operational characteristic. A quantity metric of the pile is determined based on the 3D model of the pile.
Abstract:
The present invention relates to a method for generating a risk map indicating predicted voxel-by-voxel probability of tissue infarction for a set of voxels, the method comprising the steps of, receiving for each voxel a first value (x) corresponding to a set of tissue marker values and generating the risk map, using a statistical model based on data from a group of subjects, and a stochastic variable, wherein the statistical model also comprises a second value (z i ), being based on the stochastic variable, such as the second value modelling non- measured values. The invention may be seen as advantageous since it acknowledges subject variability in probability of tissue infarction on a voxel-by- voxel basis by taking non-measured values into account, which in turn may enable providing more reliable estimates of probability of infarction.
