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.
摘要翻译：本公开描述了一种用于将对象的二维图像变换为重建对象的三维轮廓的三维表示或模型的系统和方法。在一个示例中，三对对称点建立原始图像和虚拟图像之间的初始关系，然后重建原始图像中的附加对对称点。在每对中，可视点和闭塞点被映射到具有表征所有对的映射的单个自由变量的3空间中。然后选择自由变量的值以最大化模型的紧凑性，其中紧凑度被定义为模型体积及其表面积的函数。 “噪声”修正来源于实现对称性，并为模型选择最佳拟合多面体。替代实施例将其扩展到附加的多面体，添加图像分割，使用透视图，并将其推广到不对称多面体和非多面体对象。

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。

摘要： A hard disk drive with a circuit that provides a control signal to a voice coil motor to move a head across a disk. The disk drive includes a circuit that provides a control signal to the voice coil motor to move the head. The circuit also has a state predictor and an inversion filter that compute a vibration estimate used to detect a vibration in the drive. When a threshold vibration is detected a vibration estimate is combined with the control signal to compensate for the vibration. The circuit detects the vibration without the need for an accelerometer or other sensor.
