摘要： Disclosed herein are methods, systems, and computer-readable storage media for generating three-dimensional (3D) images of a scene. According to an aspect, a method includes capturing a real-time image and a first still image of a scene. Further, the method includes displaying the real-time image of the scene on a display. The method also includes determining one or more properties of the captured images. The method also includes calculating an offset in a real-time display of the scene to indicate a target camera positional offset with respect to the first still image. Further, the method includes determining that a capture device is in a position of the target camera positional offset. The method also includes capturing a second still image. Further, the method includes correcting the captured first and second still images. The method also includes generating the three-dimensional image based on the corrected first and second still images.

摘要： Disclosed is a concept for computer-assisted procedures of surgery and diagnosis that target rigid, non-deformable anatomical parts such as bone, tissue, or teeth. The disclosure describes attaching small visual markers to instruments and anatomy of interest (e.g. bone surface), with each marker having a printed known pattern for detection and unique identification in images acquired by a free-moving camera, and a geometry that enables estimating its rotation and translation with respect to the camera using solely image processing techniques.

摘要： A high-throughput optical sectioning three-dimensional imaging system which includes: a light beam modulation module configured to modulate a light beam into a modulated light beam capable of being focused on a focal plane of an objective lens and being defocused on a defocusing plane of the objective lens; an imaging module configured to employ a camera to image, in different rows of pixels, a sample under illumination of the modulated light beam; a cutting module configured to cut off an imaged surface layer of the sample; a demodulation module configured to demodulate a sample image of one sample strip of one surface layer into an optical sectioning image, and reconstruct the optical sectioning image of each sample strip of each surface layer into a three-dimensional image. The present disclosure achieves imaging of a whole sample by dividing the sample into at least one surface layer, dividing the at least one surface layer into at least one sample strip, and imaging each sample strip. When a multi-layer imaging cannot be performed, the imaged part can be cut off by the cutting module to realize imaging of any layer of the sample, thereby improving the imaging speed and efficiency.

摘要： A method for forming a point cloud corresponding to the topography of an imaged environment involves acquiring an image of the environment with a camera having a WFOV lens mounted on a vehicle; changing the camera pose by an adjustment greater than a threshold; and acquiring another image of the environment with the camera at the changed pose. The images are mapped onto respective surfaces to form respective mapped images, defined by the same nonplanar geometry. One of the mapped images is divided into blocks of pixels. For each block, a depth map is formed by performing a search through the other mapped image to evaluate a disparity in the position of the location of the block of pixels in each of the mapped images. The depth map is converted into a partial point cloud corresponding to the local topography of the environment surrounding the vehicle as it moves through the environment.

摘要： Systems and methods are disclosed for directed image capture of a subject of interest, such as a home. Directed image capture can produce higher quality images such as more centrally located within a display and/or viewfinder of an image capture device, higher quality images have greater value for subsequent uses of captured images such as for information extraction or model reconstruction. Graphical guide(s) facilitate content placement for certain positions and quality assessments for the content of interest can be calculated such as for pixel distance of the content of interest to a centroid of the display or viewfinder, or the effect of obscuring objects. Quality assessments can further include instructions for improving the quality of the image capture for the content of interest.

摘要： An information handling system includes a RGB digital camera and a secondary digital camera that can be any type of two-dimensional or three-dimensional digital camera known in the art and a processor. The processor executes code instructions of a gross-level input detection system to detect objects in images taken contemporaneously by the RGB digital camera and the secondary digital camera using object detection techniques, and to calculate the positions of regions of interest within those objects. Further, the processor executes code instructions to detect the orientation of regions of interest within identified objects, and to associate those orientations, changes in orientations, or movement of regions of interest with user commands.

摘要： A three-dimensional model of an object is employed to aid in navigation among a number of images of the object taken from various viewpoints. In general, an image of an object such as a digital photograph is displayed in a user interface or the like. When a user selects a point within the display that corresponds to a location on the surface of the object, another image may be identified that provides a better view of the object. In order to maintain user orientation to the subject matter while navigating to this destination viewpoint, the display may switch to a model view and a fly-over to the destination viewpoint may be animated using the model. When the destination viewpoint is reached, the display may return to an image view for further inspection, marking, or other manipulation by the user.
