摘要： Mechanical surface of rotational elements for motion compensation of a locomotive object. A single layer of rotational elements formed as a mechanical surface on which a human can stand and/or move, and which automatically compensates for diverse human locomotion such as translation in two dimensions and rotation. The surface can be used to actively sense and compensate for varying speeds of human motion while in locomotion on the surface. The layer allows a user to move freely within a confined area and to be maintained within the confined area via motion compensation. Thus, the surface is particularly suited for immersion visualization environments where user motion on the surface is translated into user navigation through a virtual environment such as for computer games and simulation without necessitating constraints on immersive scene projection or participant motion.

摘要： Technologies are described herein for validating and correcting map data using oblique images or aerial photographs taken at oblique angles to the earth's surface. Pixels within oblique images can be analyzed to detect, validate, and correct other sources of data used in generating maps such as vector data, elevation maps, projection parameters, and three-dimensional model data. Visibility and occlusion information in oblique views may be analyzed to reduce errors in either occluding or occluded entities. Occlusion of road segments due to foliage, z-ordering of freeways, tunnels, bridges, buildings, and other geospatial entities may be determined, validated, and corrected. A learning algorithm can be trained with image-based descriptors that encode visible data consistencies. After training, the algorithm can classify errors and inconsistencies using combinations of different descriptors such as color, texture, image-gradients, and filter responses.

摘要： A method and system of creating an oblique display with additional detail such as texture and labels is disclosed. The footprint of objects on the image on a digital elevation map may be determined and an outline of the objects may be determined by creating object polygons that outline the bounds of the objects. The objects that are visible in the image and the objects that are occluded are determined using the footprint of the objects and the object polygons. The occluded object sections may be displayed in a modified form as part of the occluding object. Label display locations may be evaluated for objects to determine an optimal label display location based on a label criteria function and labels may be added to the objects in the image at the optimal label display location.

摘要： The present localization system determines a precise location for an address based on images. Some implementations identify the precise location using one image. Other implementations identify the precise location using multiple images. While still other implementations identify the precise location by interpolation, which uses precise locations of addresses nearby that were previously localized using one or more images. The images used in determining the precise locations have a visual feature associated with the address appearing in the image.

摘要： To reduce the amount of storage space and computing power required to render image data, particularly building image data, primary and secondary colors may be extracted from the image data. The image data may be re-rendered using only the primary and secondary colors. The re-rendered image may be evaluated for patterns, the patterns thresholded to bi-level data and a Discrete Fourier Transform (DFT), or equivalent, may be performed on the bi-level data. Low order coefficients may be discarded depending on level accuracy desired. DFT coefficients and color data for the primary and secondary colors may then be used to construct an abstraction of the original image data, using data that is, in some cases, three or four orders of magnitude smaller than the original image data.
摘要翻译：为了减少渲染图像数据所需的存储空间和计算能力，特别是构建图像数据，可以从图像数据中提取主要和次要颜色。可以仅使用主要和次要颜色来重新渲染图像数据。可以对图像进行评估，可以对双电平数据执行阈值为双电平数据的模式和离散傅里叶变换（DFT）或等同物。可以根据期望的等级精度来丢弃低阶系数。然后可以使用用于主色和次色的DFT系数和颜色数据来构造原始图像数据的抽象，使用在某些情况下比原始图像数据小三到四个数量级的数据。
