Disclosed herein are methods, apparatus, and computer program code for object manufacturing (e.g. 3D printing), to align an object scan obtained from a manufactured object manufactured according to an object data file with an object representation obtained from the object data file. The manufactured object has been manufactured on a manufacturing bed of a 3D manufacturing apparatus according to the object data file. The manufactured object comprises a manufacturing parameter identifier in a region of interest defined in the object data file, the manufacturing parameter identifier indicating a manufacturing parameter of the manufactured object. The manufacturing parameter identifier in the region of interest of the aligned object scan may be computationally read.

An apparatus for visual navigation of a UAV includes a geo-fiducial mat and a plurality of geo-fiducials. The geo-fiducial mat includes a landing pad region that provides a location for aligning with a landing pad of a UAV. The geo-fiducials each includes a two-dimensional (2D) pattern that visually conveys a code. The 2D pattern has a shape from which a visual navigation system of the UAV can visually triangulate a position of the UAV.

A method for controlling a vehicle is provided. The vehicle includes an image capturing device. The method includes: controlling the image capturing device to collect an image of a scene where the vehicle is located; acquiring projection information of a projection pattern in the image; determining image-altering information corresponding to the projection pattern according to the projection information; and controlling movement of the vehicle according to the image-altering information.

While operating a vehicle, a candidate marker is detected via first image data from a first image sensor. Upon failing to identify the candidate marker, vehicle exterior lighting is actuated to illuminate the candidate marker. Then the candidate marker is determined to be one of a real marker or a projected marker based on determining whether the candidate marker is detected via second image data from the first image sensor. Upon determining the candidate marker is the real marker, the vehicle is operated based on the real marker.

The present invention relates to a robust method for optical recognition of markers in an outdoor environment. In this context, the present invention provides a method for optical recognition of optical markers comprising the steps of: acquiring an image; identifying regions of contiguous colours in the image by flood filling; extracting data and parameters of the contiguous regions; and detecting an optical marker by means of a convex hull algorithm and prediction of position of squares based on the data and parameters extracted from the contiguous Thus, the method of the present invention allows identification of markers, such as chequerboards and targets, unequivocally and with enough robustness as regards partial occlusions and variations of illumination.

A magnetic stimulation system may include first and second subsystems. The first subsystem may include a first stimulator, a first coil, and a first processor configured to determine stimulation parameter data for a subject. The second subsystem may include a second stimulator, a headpiece including an identifier and a second coil mounted to a headpiece body at a fixed location, an image recording device, and a second processor configured to: receive first image data for one or more first images of the subject and headpiece; receive, from the image recording device, second image data for one or more second images of the subject and headpiece; determine, using the first and second image data, that the stimulation parameter data corresponds to the subject; determine, using the second image data, that the headpiece corresponds to the subject; and determine, using the second image data, that the headpiece is at a pre-determined position.

The present disclosure relates to augmented reality, virtual reality, mixed reality, and extended reality systems, and more specifically, to systems and methods for a visual positioning system.

An apparatus for processing image data may include: a memory storing instructions; and a processor configured to execute the instructions to: extract a target image patch including a target object, from a captured image; obtain a plurality of landmark features from the target image patch; align the plurality of landmark features of the target image patch with a plurality of reference landmark features in a template image patch including the same target object; and when the plurality of landmark features are aligned with the plurality of reference landmark features, transfer texture details of the target object in the template image patch to the target object in the target image patch.

The present invention relates to a system for monitoring a non-static clinical scenario, preferably a surgical field, such that different elements of interest can be located throughout the entire clinical event; in particular, a high-precision monitoring and distinction of critical biological tissues, such as nerves or blood vessels, is sought.

A method for sharing a point-of-interest across a plurality of video feeds from a plurality of optical imaging devices includes receiving an indication of the point-of-interest associated with a first video feed of the plurality of video feeds, the first video feed provided by a first optical imaging device of the plurality of optical imaging devices; determining a geo-location of an object associated with the point-of-interest; determining a position of a second optical imaging device relative to the determined geo-location of the point-of-interest; and overlaying the point-of-interest on a second video feed, the second video feed provided by the second optical imaging device.
