Abstract: A method comprising applying an object recognition pipeline to frames of video data. The object recognition pipeline provides a mask output of objects detected in the frames. The method includes fusing the mask output of the object recognition pipeline with depth data associated with the frames of video data to generate a map of object instances, including projecting the mask output to a model space for the map of object instances using a camera pose estimate and the depth data. An object instance in the map of object instances is defined using surface-distance metric values within a three-dimensional object volume, and has an object pose estimate indicating a transformation of the object instance to the model space. The object pose estimate and the camera pose estimate form nodes of a pose graph for the map of model instances.

Abstract: A compression screw driver system including a drive member having a shaft extending from a proximal end to a distal end. A drive selection member is positioned about the shaft and is axially moveable along the shaft between an engagement position and a disengaged position. A distal portion of the drive selection member defines a first engagement structure. A compression sleeve is positioned over the distal end of the shaft. The proximal end of the compression sleeve defines a second engagement structure which complements the first engagement structure and the distal end of the compression sleeve defines a contact surface. In the engagement position the first and second engagement structures are engaged and the compression sleeve rotates with the drive member and in the disengaged position the first and second engagement structures are disengaged and the compression sleeve remains stationary while the drive member rotates.

Abstract: Certain examples described herein enable semantically-labelled representations of a three-dimensional (3D) space to be generated from video data. In described examples, a 3D representation is a surface element or ‘surfel’ representation, where the geometry of the space is modelled using a plurality of surfaces that are defined within a 3D co-ordinate system. Object-label probability values for spatial elements of frames of video data may be determined using a two-dimensional image classifier. Surface elements that correspond to the spatial elements are identified based on a projection of the surface element representation using an estimated pose for a frame. Object-label probability values for the surface elements are then updated based on the object-label probability values for corresponding spatial elements. This results in a semantically-labelled 3D surface element representation of objects present in the video data.
