摘要:
A method for aligning images includes (1) selecting a pair of overlapping pixels when two second image are aligned with a camera motion; (2) if both pixels are edge pixels, incrementing a correlation value between the two images for the camera motion; (3) if only one of pixels is an edge pixel, decrementing the correlation value between the two images for the camera motion; (4) repeating steps (1) to (3) for other pairs of overlapping pixels in the two images to determine the correlation value for the camera motion. The method further includes (5) repeating steps (1) to (4) for other camera motions; (6) selecting camera motions having large correlation values; (7) determining matched edge counts for members of the group; (8) selecting the camera motion with the largest matched edge count; and (8) aligning the two images with the selected camera motion.

A method for improving image resolution includes (a) selecting a low-resolution pixel in a low-resolution image; (b) generating a vector that characterizes a low-resolution patch about the low-resolution pixel; (c) classifying the low-resolution patch into one of a plurality of possible patterns; (d) if said one pattern is one of a plurality of top ranking patterns having filters, applying a filter of said one of the top ranking patterns to the low-resolution patch to generate high-resolution pixels that correspond to the low-resolution pixel; (e) if said one pattern is not one of the plurality of top ranking patterns, applying an interpolation process to the low-resolution patch to generate the high-resolution pixels; (f) repeating steps (a) to (e) for additional low-resolution pixels to generate additional high-resolution pixels to form a high-resolution image.

Systems and methods for generating three-dimensional models of an object use images having unmeasured camera parameters. Camera calibration determines the perspective of the camera from the content of the images. A background having a pattern with a known marks in each image can facilitate determination of the camera parameters. One background pattern includes separated marks having rectangular sections where corners of the rectangular sections provide calibrations points for the camera parameters. The camera parameters can also be determined by matching features of the object in different images and determining differences in perspective from differences in the appearance of the matched features in different images. A combination of projective and metric reconstructions provides robust reconstruction.

A method for correcting a nonlinear distortion in an image includes receiving an image of a calibration template comprising calibration patterns, detecting at least three points from the calibration patterns, calculating a distortion parameter from coordinates of the at least three points that should align along a straight line, and correcting the nonlinear distortion in the image using the distortion parameter. A method for correcting a radial distortion in an image includes receiving a radial distortion parameter from the user and calculating new intensity values of points in the image to correct a radial exposure distortion in the image.

An image sensor includes an array of light sensitive elements and a filter array. Each filter element is in optical communication with a respective light sensitive element. The image sensor receives filtered light having a repeating pattern. Light sensitive elements in at least two successive rows alternately receive light having a first color and a second color, and light sensitive elements in common columns of the successive rows alternately receive light having the first color and the second color. Light sensitive elements in at least two additional successive rows alternately receive light having a third and a fourth color, and light sensitive elements in common columns of the additional successive rows alternately receive light having the third color and the fourth color. Output values of pairs of sampled light sensitive elements receiving light of a common color and from successive rows are combined to generate a down-sampled image.

摘要:
An architectural planning system, that includes software and the process thereof, which actively tracks the relationship of organizational groups as well as the required connections therebetween, which information can be actively taken into account during an architectural planning phase. Generally, this provides an improved software tool and process for planning the physical locations of organizational groups within the building space. Further, changes in organizational needs can be readily modified and adapted through direct and dynamic collaboration between these parties.
摘要:
An image sensor for three-dimensional (“3D”) imaging includes a first, a second, and a third pixel unit, where the second pixel unit is disposed between the first and third pixel units. Optical filters included in the pixel units are disposed on a light incident side of the image sensor to filter polarization-encoded light having a first polarization and a second polarization to photosensing regions of the pixel units. The first pixel unit includes a first optical filter having the first polarization, the second pixel unit includes a second optical filter having the second polarization, and the third pixel unit includes a third optical filter having the first polarization.
