    摘要: A flow monitoring device (26) for monitoring mud flow in a return line (25) of a bore hole drilling operation, including a mounting bracket (32) mounted to the return line (25) with a viewing port (36) for access to an interior of the return line. A light source illuminates (42), through the viewing port, a portion of the mud flow in an observation zone within the return line. A camera (44) creates a plurality of images of the mud flow in the observation zone. A controller (46) is configured to analyze the plurality images to: determine a level of the mud flow in the return line and the presence of at least one irregularity, track a movement of the irregularity across the plurality of images to determine a rate of movement of the irregularity, and calculate a flow rate of the mud flow through the return line based on the movement rate and the determined level.

    摘要: A process includes acquiring radar images on the same area, calculating a vector of n amplitude or intensity values relating to a sample pixel in the n images available, identifying the vector as a sample vector, and defining an estimation window for the sample pixel for identifying a set of pixels around the sample pixel. Additionally, calculating vectors of N amplitude or intensity values for each pixel contained in the estimation window, comparing each vector with the sample vector, identifying pixels associated with the vectors that have passed a statistical test and identifying pixels associated with the vectors that have not passed the statistical test, eliminating the pixels contained in the estimation window that are not connected to the sample pixel, and identifying the set of pixels that are statistically homogeneous with the sample pixel.

    摘要: A seismic modeling system may include a seismic model data storage device, and a processor cooperating with the seismic model data storage device to determine a first 3D boundary around a suspect region within a first seismic model spatial domain data set for a geological formation at a first time, and determine a second 3D boundary around the suspect region within a second seismic model spatial domain data set for the geological formation at a second time and after movement of the suspect region. The processor may also compare the second 3D boundary to the first 3D boundary to determine an overlapping portion where the first and second 3D boundary regions overlap, and at least one non-overlapping portion where the first and second 3D boundaries do not overlap, and inpaint the overlapping portion based upon the at least one non-overlapping portion.

    摘要: The invention relates to a method for colourising a three-dimensional point cloud, wherein the method comprises: With a surveying instrument, surveying a point cloud of a setting, wherein each point of said point cloud is characterised by coordinates within an instrument coordinate system, which has an instrument centre as origin. With a first camera, capturing a first image of the setting, wherein each pixel value of the first image is assigned to coordinates within a first camera coordinate system, which has a first projection centre as origin, wherein the first projection centre has first parallax shift relative to the instrument centre. With a computer comprised by the surveying instrument: Transforming the point cloud from the instrument coordinate system into the first camera coordinate system, resulting in a first transformed point cloud. Within the first transformed point cloud, detecting one or more uncovered points, which are openly visible from the perspective of the first projection centre. To each uncovered point in the first transformed point cloud, assigning a pixel value, which has corresponding coordinates in the first camera coordinate system.

    摘要: A method for navigation comprises constructing a current map that includes two-dimensional or three dimensional representations of an area, detecting one or more edge features on the current map, and generating a first fine-edge map based on the edge features. The method further comprises retrieving a historical map that includes two-dimensional or three dimensional representations of the area, detecting one or more edge features on the historical map, and generating a second fine-edge map based on the edge features. Thereafter, a coarse version of the current map is generated from the first fine-edge map, and a coarse version of the historical map is generated from the second fine-edge map. The coarse versions of the current and historical maps are then correlated to determine a first position and orientation. The first fine-edge map is then correlated with the second fine-edge map to determine a second, more accurate, position and orientation.
