Abstract: Robotic and/or measurement devices, systems, and methods for telesurgical and other applications employ input devices operatively coupled to tools so as to allow a system user to manipulate tissues and other structures being measured. The system may make use of three dimensional position information from stereoscopic images. Two or more discrete points can be designated in three dimensions so as to provide a cumulative length along a straight or curving structure, an area measurement, a volume measurement, or the like. The discrete points may be identified by a single surgical tool or by distances separating two or more surgical tools, with the user optionally measuring a structure longer than a field of view of the stereoscopic image capture device by walking a pair of tools “hand-over-hand” along the structure. By allowing the system user to interact with the tissues while designating the tissue locations, and by employing imaging data to determine the measurements, the measurement accuracy and ease of measurement may be enhanced.

Abstract: An endoscope with a stereoscopic optical channel is held and positioned by a robotic surgical system. A capture unit captures (1) a visible first image and (2) a visible second image combined with a fluorescence second image from the light. An intelligent image processing system receives (1) the visible first image and (2) the visible second image combined with the fluorescence second image and generates at least one fluorescence image of a stereoscopic pair of fluorescence images and a visible second image. An augmented stereoscopic display system outputs a real-time stereoscopic image including a three-dimensional presentation including in one eye, a blend of the at least one fluorescence image of a stereoscopic pair of fluorescence images and one of the visible first and second images; and in the other eye, the other of the visible first and second images.

Abstract: A sentient system combines detection, tracking, and immersive visualization of a cluttered and crowded environment, such as an office building, terminal, or other enclosed site using a network of stereo cameras. A guard monitors the site using a live 3D model, which is updated from different directions using the multiple video streams. As a person moves within the view of a camera, the system detects its motion and tracks the person's path, it hands off the track to the next camera when the person goes out of that camera's view. Multiple people can be tracked simultaneously both within and across cameras, with each track shown on a map display. The track system includes a track map browser that displays the tracks of all moving objects as well as a history of recent tracks and a video flashlight viewer that displays live immersive video of any person that is being tracked.

Abstract: The present disclosure relates to calibration target devices, assemblies and methods for use with imaging systems, such as a stereoscopic endoscope. A calibration assembly includes: a target surface extends in three dimensions with calibration markers and a body with an interface that engages an endoscope so the markers are within the field of view. A first calibration marker extends along a first plane of the target surface and a second marker extends along a second plane of the target surface. The planes are different and asymmetric relative to the field of view as seen through the endoscope. Three-dimensional targets, in particular, enable endoscopic calibration using a single image (or pair of images for a stereoscopic endoscope) to reduce the calibration process complexity, calibration time and chance of error as well as allow the efficient calibration of cameras at different focus positions.

Abstract: The present disclosure relates to an inertia measurement module for an unmanned aircraft, which comprises a housing assembly, a sensing assembly and a vibration damper. The vibration damper comprises a first vibration-attenuation cushion; and the sensing assembly comprises a first circuit board, a second circuit board and a flexible signal line for connecting the first circuit board and the second circuit board. An inertia sensor is fixed on the second circuit board, and the first circuit board is fixed on the housing assembly. The inertia measurement module further comprises a weight block, and the second circuit board, the weight block, the first vibration-attenuation cushion and the first circuit board are bonded together. The present disclosure greatly reduces the influence of the operational vibration frequency of the unmanned aircraft on the inertia sensor and improves the measurement stability of the inertia sensor.

Abstract: In some embodiments, remote graphics rendering may be facilitated by causing thin clients, that send raw graphics data to a local server for rendering, to downscale the data to a size appropriate for use by the local server. In some embodiments this avoids the storage of unnecessary data which is not useful for the local server because the actual display size on the local server is smaller than what the transmitted raw data would permit.

In the first state, a surface having an aperture of at least one of the one or more image capture elements is enclosed within the outer surface of the surgical instrument so that the surface having the aperture does not extend beyond the outer surface. In a second state, the one or more image capture elements are deployed. In the second state the surface having the aperture of the at least one of the one or more image capture elements extends beyond the outer surface.
