摘要： The present disclosure describes a system and method for transforming a two-dimensional image of an object into a three-dimensional representation, or model, that recreates the three-dimensional contour of the object. In one example, three pairs of symmetric points establish an initial relationship between the original image and a virtual image, then additional pairs of symmetric points in the original image are reconstructed. In each pair, a visible point and an occluded point are mapped into 3-space with a single free variable characterizing the mapping for all pairs. A value for the free variable is then selected to maximize compactness of the model, where compactness is defined as a function of the model's volume and its surface area. “Noise” correction derives from enforcing symmetry and selecting best-fitting polyhedra for the model. Alternative embodiments extend this to additional polyhedra, add image segmentation, use perspective, and generalize to asymmetric polyhedra and non-polyhedral objects.

摘要： A system processes 2D images of 2D or 3D objects, creating a model of the object that is consistent with the image and as veridical as the perception of the 2D image by humans. Vertices of the object that are hidden in the image are recovered by using planarity and symmetry constraints. The 3D shape is recovered by maximizing 3D compactness of the recovered object and minimizing its surface area. In some embodiments, these two criteria are weighted by using the geometric mean.
摘要翻译：系统处理2D或3D对象的2D图像，创建与图像一致的对象的模型，并且与人类对2D图像的感知一样真实。通过使用平面性和对称性约束来恢复隐藏在图像中的对象的顶点。通过最大化恢复对象的3D紧凑性并使其表面积最小化来恢复3D形状。在一些实施例中，通过使用几何平均值对这两个标准进行加权。

摘要： Systems and methods for processing a pair of 2-D images are described. In one example, a stereoscopic set of images is converted into a collection of regions that represent individual 3-D objects in the pair of images. In one embodiment, the system recovers the 3-D point P for each point p that appears in both images. It estimates the 3-D orientation of the floor plane, and the image capture planes and their height from the floor. The system then identifies the collection B of points P that do not represent points on the floor and generates a projection C of B onto a plane parallel to the floor. It blurs the projection C and identifies peaks in the blurred image, then fits symmetric figures to the points in C around the identified peaks. The system projects the 3-D figures associated with the symmetric figures back onto the 2-D images.

摘要： A method is provided for identifying offsets of accelerometers integrated into hard disk drives. More specifically, often, disk drives employ accelerometers that constantly monitor the acceleration felt by the disk drive. Once the accelerations are less than a predetermined threshold, a free fall event is identified and an actuator arm that is generally positioned above the disk is placed in a safe location prior to impact. Accelerometers must be calibrated prior to use such that their inherent errors are identified and factored into the algorithm that identifies free fall. The method provided herein allows for the 0 g offset to be monitored without having to reorient the device being tested, thus saving time and money.
摘要翻译：提供了一种用于识别集成到硬盘驱动器中的加速度计的偏移的方法。更具体地，磁盘驱动器经常使用加速度计，它们不断地监视磁盘驱动器感觉到的加速度。一旦加速度小于预定阈值，则识别出自由落体事件，并且通常位于盘上方的致动器臂在冲击之前被放置在安全位置。加速度计必须在使用之前进行校准，以便确定其固有误差并将其分解到识别自由落体的算法中。本文提供的方法允许监测0g偏移量，而不必重新定向被测试的装置，从而节省时间和金钱。
