摘要： Described herein are methods, systems and apparatus to improve imaging sensor production yields. In one method, a stereoscopic image sensor pair is provided from a manufacturing line. One or more images of a correction pattern are captured by the image sensor pair. Correction angles of the sensor pair are determined based on the images of the correction pattern. The correction angles of the sensor pair are represented graphically in a three dimensional space. Analysis of the graphical representation of the correction angles through statistical processing results in a set of production correction parameters that may be input into a manufacturing line to improve sensor pair yields.

摘要： Described herein are methods and apparatus to adjust the convergence point of a stereoscopic image pair captured by an imaging device. In one method, a first image and a second image of a stereoscopic image pair are provided, and then shifting or cropping of the first image is performed to align the first and second image. This shifting or cropping is performed while preserving the second image. The method then includes determining a target horizontal image disparity based on a desired convergence point of the stereoscopic image pair and when the target horizontal disparity is greater than a predetermined maximum, the cropping of an outside dimension of the first image is limited. In some implementations it is limited to the predetermined maximum.

摘要： Described are methods and apparatus for adjusting images of a stereoscopic image pair based on keypoint matches. The quality of the key point matches is first evaluated to determine whether the quality exceeds a keypoint quality threshold. If the quality level of the keypoint matches exceeds the threshold, the vertical disparity between the images of the stereoscopic image pair can be evaluated based on vertical disparity vectors between the keypoint matches. If the vertical disparity is below a threshold, no adjustment of the stereoscopic image pair may be performed. If the vertical disparity is above the threshold, an affine correction may compensate for pitch, roll, and scale differences between the images. A projective correction may compensate for yaw differences. The vertical disparity between the two images is then evaluated after the corrections to determine if additional adjustment should be performed.
摘要翻译：描述了用于基于关键点匹配来调整立体图像对的图像的方法和设备。首先评估关键点匹配的质量以确定质量是否超过关键点质量阈值。如果关键点匹配的质量水平超过阈值，则可基于关键点匹配之间的垂直视差矢量来评估立体图像对的图像之间的垂直视差。如果垂直视差低于阈值，则可以不执行立体图像对的调整。如果垂直视差高于阈值，则仿射校正可以补偿图像之间的俯仰，滚动和缩放差异。投影校正可以补偿偏航差异。然后在校正后评估两幅图像之间的垂直差异，以确定是否应该进行额外的调整。

摘要： An interactive display, including a cover glass having a front surface that includes a viewing area provides an input/output (I/O) interface for a user of an electronic device. An arrangement includes a processor, a light source, and a camera disposed outside the periphery of the viewing area coplanar with or behind the cover glass. The camera receives scattered light resulting from interaction, with an object, of light outputted from the interactive display, the outputted light being received by the cover glass from the object and directed toward the camera. The processor determines, from image data output by the camera, an azimuthal angle of the object with respect to an optical axis of the camera and/or a distance of the object from the camera.

摘要： Systems and methods for correcting stereo yaw of a stereoscopic image sensor pair using autofocus feedback are disclosed. A stereo depth of an object in an image is estimated from the disparity of the object between the images captured by each sensor of the image sensor pair. An autofocus depth to the object is found from the autofocus lens position. If the difference between the stereo depth and the autofocus depth is non zero, one of the images is warped and the disparity is recalculated until the stereo depth and the autofocus depth to the object is substantially the same.

摘要： A method operational on a receiver device for decoding a codeword is provided. At least a portion of a composite code mask is obtained, via a receiver sensor, and projected on the surface of a target object. The composite code mask may be defined by a code layer and a carrier layer. A code layer of uniquely identifiable spatially-coded codewords may be defined by a plurality of symbols. A carrier layer may be independently ascertainable and distinct from the code layer and may include a plurality of reference objects that are robust to distortion upon projection. At least one of the code layer and carrier layer may have been pre-shaped by a synthetic point spread function prior to projection. The code layer may be adjusted, at a processing circuit, for distortion based on the reference objects within the portion of the composite code mask.
