Patent number: 11874407Abstract: Technologies for processing a three-dimensional (3D) underwater scene is disclosed. A computing device receives a data set representative of an underwater environment corresponding to sonar data generated by a sonar transducer assembly and receiving parameters. The data set includes 3D volumetric points representative of at least one 3D volumetric data set at one or more time points. The computing device applies segmentation modes on the data set, in which each segmentation mode generates a processed subset of the 3D volumetric points. Each processed subset includes one or more 3D volumetric objects. The computing device classifies one or more 3D volumetric objects based on a combination of the plurality of processed subsets.Type: GrantFiled: February 19, 2020Date of Patent: January 16, 2024Assignee: CODA OCTOPUS GROUP INC.Inventors: Alam Abbas Syed, Blair G.

Patent number: 11448755Abstract: Technologies for correcting beamformed data are disclosed. A sonar computing device receives, at two or more sets of two-dimensional (2D) subarrays of a multi-element detector array, raw data representing a three-dimensional (3D) volumetric view of a space. A first set of subarrays of the two or more sets of subarrays includes elements of the detector array along a first direction. A second set of subarrays of the two or more sets of subarrays includes elements of the detector array along a second direction. The raw data is subdivided into slices and beamformed. The beamformed data is corrected by, per slice, obtaining first phase data from the first set, obtaining second phase data from the second set, correcting a beam position of each beam in the first and second directions per voxel based on the first and second phase data, and interpolating the corrected beam positions to an output grid.Type: GrantFiled: September 18, 2020Date of Patent: September 20, 2022Assignee: CODA OCTOPUS GROUP, INC.Inventor: Charlie Pearson

Patent number: 10088566Abstract: An object is measured to record the relative surface coordinates. Then, a portion of the object “the front side” immersed in a fluid is imaged by directing a sonar pulse at the object and recording sonar signals reflected from the object with a sonar imaging array. Then, the recorded relative surface coordinates are iteratively fit to coordinates calculated from the sonar image. Thereafter, the coordinates of the surface of the “backside” of the object that is not observable in the sonar image are known, and a computer generated image of the backside is stitched to sonar image so that the object can be viewed from a plurality of viewpoints separated from the sonar imaging array.Type: GrantFiled: October 30, 2015Date of Patent: October 2, 2018Assignee: Coda Octopus Group Inc.Inventor: Martyn Sloss

Publication number: 20140064032Abstract: Sonar imaging data obtained by sending multiple sonar pings towards an object is reduced by assigning values measured by each sonar ping to bins, where each bin is fixed in World Space, and calculating the opacity of each bin to produce an image of the object. A normal vector associated with each bin is used to calculate the light reflected from a model constructed from the data. The most preferred normal vector is calculated from the vector sum of normals calculated from each ping.Type: ApplicationFiled: September 5, 2012Publication date: March 6, 2014Applicant: Coda Octopus Group, Inc.Inventor: Martyn Sloss
