20120306847 | ONLINE ENVIRONMENT MAPPING - A system and method are disclosed for online mapping of large-scale environments using a hybrid representation of a metric Euclidean environment map and a topological map. The system includes a scene module, a location recognition module, a local adjustment module and a global adjustment module. The scene flow module is for detecting and tracking video features of the frames of an input video sequence. The scene flow module is also configured to identify multiple keyframes of the input video sequence and add the identified keyframes into an initial environment map of the input video sequence. The location recognition module is for detecting loop closures in the environment map. The local adjustment module enforces local metric properties of the keyframes in the environment map, and the global adjustment module is for optimizing the entire environment map subject to global metric properties of the keyframes in the keyframe pose graph. | 12-06-2012 |
20130060540 | SYSTEMS AND METHODS THAT GENERATE HEIGHT MAP MODELS FOR EFFICIENT THREE DIMENSIONAL RECONSTRUCTION FROM DEPTH INFORMATION - Methods of generating a three dimensional representation of an object in a reference plane from a depth map including distances from a reference point to pixels in an image of the object taken from a reference point. Weights are assigned to respective voxels in a three dimensional grid along rays extending from the reference point through the pixels in the image based on the distances in the depth map from the reference point to the respective pixels, and a height map including an array of height values in the reference plane is formed based on the assigned weights. An n-layer height map may be constructed by generating a probabilistic occupancy grid for the voxels and forming an n-dimensional height map comprising an array of layer height values in the reference plane based on the probabilistic occupancy grid. | 03-07-2013 |
20140270480 | DETERMINING OBJECT VOLUME FROM MOBILE DEVICE IMAGES - Techniques are described for analyzing images acquired via mobile devices in various ways, including to estimate measurements for one or more attributes of one or more objects in the images. For example, the described techniques may be used to measure the volume of a stockpile of material or other large object, based on images acquired via a mobile device that is carried by a human user as he or she passes around some or all of the object. During the acquisition of a series of digital images of an object of interest, various types of user feedback may be provided to a human user operator of the mobile device, and particular images may be selected for further analysis in various manners. Furthermore, the calculation of object volume and/or other determined object information may include generating and manipulating a computer model or other representation of the object from selected images. | 09-18-2014 |
20150138069 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR UNIFIED SCENE ACQUISITION AND POSE TRACKING IN A WEARABLE DISPLAY - Methods, systems, and computer readable media for unified scene acquisition and pose tracking in a wearable display are disclosed. According to one aspect, a system for unified scene acquisition and pose tracking in a wearable display includes a wearable frame configured to be worn by a user. Mounted on the frame are: at least one sensor for acquiring scene information for a real scene proximate to the user, the scene information including images and depth information; a pose tracker for estimating the user's head pose based on the acquired scene information; a rendering unit for generating a virtual reality (VR) image based on the acquired scene information and estimated head pose; and at least one display for displaying to the user a combination of the generated VR image and the scene proximate to the user. | 05-21-2015 |

20140130300 | Releasable Ball Lock Hinge - A releasable ball lock hinge is disclosed. The releasable ball lock hinge includes a first body operable with a hinge ball and a release ball. Each ball can be movable within respective openings of the first body. The releasable ball lock hinge also includes a second body configured to rotatably interface and removably couple with the first body. The hinge ball releasably engages the second body. The second body has a release recess operable with the release ball to disengage the hinge ball and alternately couple and release the first body and the second body based on a relative position between the first body and the second body. | 05-15-2014 |
20140192414 | VARIABLE LENGTH LIGHT SHIELD FOR AN ELECTRO-OPTICAL SENSOR WITHIN A NOSE CONE - A variable length light shield is disclosed for an electro-optical sensor within a nose cone. The light shield includes a base, a telescopic shade supported by the base, and a ring rotatably supported about the base. The light shield also includes a guide tube disposed proximate the ring with an end extending away from the ring about a side of the telescopic shade. The light shield further includes an extension spring supported by the guide tube with an end coupled to the telescopic shade. Additionally, the light shield includes a cable extending through the guide tube and the extension spring, with one end of the cable coupled to the ring and another end of the cable coupled to the telescopic shade. The extension spring is configured to exert a force on the telescopic shade to extend the telescopic shade. Rotation of the ring causes retraction of the telescopic shade. | 07-10-2014 |
