Patent number: 11508078Abstract: A system is provided for automatic identification and annotation of objects in a point cloud in real time. The system can automatically annotate a point cloud that identifies coordinates of objects in three-dimensional space while data is being collected for the point cloud. The system can train models of physical objects based on training data, and apply the models to point clouds that are generated by various point cloud generating devices to annotate the points in the point clouds with object identifiers. The solution of automatically annotated point cloud can be used for various applications, such as blueprints, map navigation, and determination of robotic movement in a warehouse.Type: GrantFiled: August 5, 2020Date of Patent: November 22, 2022Assignee: Lineage Logistics, LLCInventors: Christopher Frank Eckman, Alexander Ming Zhang

Publication number: 20220351464Abstract: This specification describes systems and methods for refining point cloud data. Methods can include receiving point cloud data for a physical space, iteratively selecting points along an x, y, and z dimension, clustering the selected points into 2D histograms, determining a slope value for each 2D histogram, and removing, based on the slope value exceeding a predetermined value, points from the point cloud data. Methods can also include iteratively voxelizing each 2D histogram into predetermined mesh sizes, summating points in each voxelized 2D histogram, removing, based on determining the summation is below a predetermined sum value, points from the point cloud data, keeping, based on determining that a number of points in each voxelized 2D histogram exceeds a threshold value, a center point, selecting, for each histogram, a point, identifying, nearest neighbors in the point cloud data, removing the identified nearest neighbors from the data, and returning remaining points.Type: ApplicationFiled: July 11, 2022Publication date: November 3, 2022Inventors: Christopher Frank Eckman, Brady Michael Lowe, Alexander Hall

Publication number: 20220291412Abstract: A metal detector that uses a verity of sensors as input for a neural network to optimize discrimination and detection of known or unknown objects. The detector will also have employ an user defined frequencies that will help to create custom settings. The detector will be able to use the sweeping motion of the detector head to create many frames of reference for understanding the composition, depth, size, type, approximant length of time it had remained, and to some extent orientation of known/unknown objects. This will be fed back to a user who can help identify the object once it is found. If it is different or new, the user can enter what it was into a database that can be used to train signals for future use, such as through using the data for training and/or updating machine learning models which can be used to accurately identify object.Type: ApplicationFiled: March 14, 2022Publication date: September 15, 2022Inventor: Christopher Frank Eckman
