摘要： Techniques are described for passive three-dimensional image sensing based on referential image blurring. For example, a filter mask is integrated with a lens assembly to provide one or more normal imaging bandpass (NIB) regions and one or more reference imaging bandpass (RIB) regions, the regions being optically distinguishable and corresponding to different focal lengths and/or different focal paths. As light rays from a scene object pass through the different regions of the filter mask, a sensor can detect first and second images responsive to those light rays focused through the NIB region and the RIB region, respectively (according to their respective focal lengths and/or respective focal paths). An amount of blurring between the images can be measured and correlated to an object distance for the scene object. Some embodiments project additional reference illumination to enhance blurring detection in the form of reference illumination flooding and/or spotted illumination.

摘要： In a measurement device, a controller causes an imaging unit to generate a plurality of first pictures based on a first image and a plurality of second pictures based on a second image. The controller determines whether or not there is blurring on the basis of at least two of the plurality of first pictures. The controller determines whether or not there is blurring on the basis of at least two of the plurality of second pictures. The controller causes a measurement unit to perform measurement when the controller determines that there is no blurring in first picture blurring determination and second picture blurring determination.

摘要： A visualization technique for a vehicle and a vehicle driver combines a forward facing video camera and a forward facing time of flight camera. The outputs of the camera are combined to provide the vehicle driver with an augmented reality display, whereby topographical features can be identified in relation to the vehicle even if out of line of sight of the driver.

摘要： Systems and methods are described for defining a set of images based on captured images, receiving a viewing direction associated with a user of a virtual reality (VR) head mounted display, receiving an indication of a change in the viewing direction. The methods further include configuring, a re-projection of a portion of the set of images, the re-projection based at least in part on the changed viewing direction and a field of view associated with the captured images, and converting the portion from a spherical perspective projection into a planar perspective projection, rendering by the computing device and for display in the VR head mounted display, an updated view based on the re-projection, the updated view configured to correct distortion and provide stereo parallax in the portion, and providing, to the head mounted display, the updated view including a stereo panoramic scene corresponding to the changed viewing direction.

摘要： Disclosed are a device and a method of hand tracking based on a tailored illumination profile. In some embodiments, the hand tracking device includes an illumination module, an imaging sensor and a processor. The illumination module provides an illumination profile that matches a predicted interaction volume within which a user of the near-eye display device is expected to place a body part of the user to interact with a user interface of the near-eye display device. The imaging sensor receives light reflected by an environment of the near-eye display device including the body part of the user and generates depth values corresponding to depths of the environment relative to the near-eye display device. The processor tracks a location of the body part of the user based on the depth values and determines an adjustment of an illumination intensity of the illumination module based on the location of the body part of the user.

摘要： In a measuring device, a second objective optical system is arranged to have a parallax with respect to a first objective optical system. An imaging unit captures a first subject image formed through the first objective optical system at a first imaging timing and captures a second subject image formed through the second objective optical system at a second imaging timing different from the first imaging timing. A virtual image generating unit generates a virtual image based on the first subject image acquired in a case in which the imaging unit is assumed to capture the first subject image at the second imaging timing. A measurement processing unit measures a shape of a subject on the basis of a second image based on the second subject image and the virtual image.

摘要： A 3D coordinate measuring system includes a six-DOF unit having a unit frame of reference and including a structure, a retroreflector, a triangulation scanner, and an augmented reality (AR) color camera. The retroreflector, scanner and AR camera are attached to the structure. The scanner includes a first camera configured to form a first image of the pattern of light projected onto the object by a projector. The first camera and projector configured to cooperate to determine first 3D coordinates of a point on the object in the unit frame of reference, the determination based at least in part on the projected pattern of light and the first image. The system also includes a coordinate measuring device having a device frame of reference and configured to measure a pose of the retroreflector in the device frame of reference, the measured pose including measurements of six degrees-of-freedom of the retroreflector.

摘要： A method for generating a three-dimensional virtual representation includes performing a first scan of the physical object while the physical object has a first position. A displayed visualization of the physical object is generated based on the first scan. Aligning input is received that causes increased correspondence between the displayed visualization and a second position of the physical object. A second scan of the physical object is performed while the object is in the second position. Based on the first scan and the second scan, a three-dimensional virtual representation of the physical object is generated.
