    • One embodiment of the invention provides a method and apparatus for decompressing a compressed data set using a processing device having a plurality of processing units and a shared memory. The compressed data set comprises a plurality of compressed data segments, in which each compressed data segment corresponds to a predetermined size of uncompressed data. The method includes loading the compressed data set into the shared memory so that each compressed data segment is stored into a respective memory region of the shared memory. The respective memory region has a size equal to the predetermined size of the corresponding uncompressed data segment. The method further includes decompressing the compressed data segments with the processing units; and storing each decompressed data segment back to its respective memory region within the shared memory.
    • 本发明的一个实施例提供一种使用具有多个处理单元和共享存储器的处理装置解压缩压缩数据集的方法和装置。 压缩数据集包括多个压缩数据段,其中每个压缩数据段对应于预定大小的未压缩数据。 该方法包括将压缩数据集加载到共享存储器中,使得每个压缩数据段被存储到共享存储器的相应存储器区域中。 相应的存储器区域具有等于对应的未压缩数据段的预定大小的大小。 该方法还包括用处理单元解压缩压缩数据段; 以及将每个解压缩的数据段存储回共享存储器内的其各自的存储器区域。

    • A method of forming a two dimensional map of a three dimensional environment, there being a map origin located in the three dimensional environment, a viewing direction vector defined passing through the map origin, and a one-to­-one correspondence between map positions in the map and the directions of vectors passing through the map origin; comprises the steps of: associating an environment position in the three dimensional environment with a folded vector that passes through the map origin, the folded vector lying in a plane containing both the viewing direction vector and the environment position and forming an angle with the viewing direction vector that is a predetermined function of the angle between the viewing direction vector and a vector between the map origin and the environment position; associating an environment position with the map position corresponding to the direction of the folded vector associated with that environment position; and deriving properties for a map position from the properties of the corresponding environment position.
    • 一种形成三维环境的二维地图的方法,存在位于三维环境中的地图起点,通过地图起点定义的观察方向矢量,以及在地图位置中的一对一对应关系 地图和通过地图起源的向量的方向; 包括以下步骤:将三维环境中的环境位置与穿过地图原点的折叠矢量相关联,折叠矢量位于包含观察方向矢量和环境位置的平面中,并与观察方向形成角度 矢量,其是观察方向矢量与地图原点与环境位置之间的矢量之间的角度的预定函数; 将环境位置与对应于与该环境位置相关联的折叠向量的方向的地图位置相关联; 并从相应的环境位置的属性导出地图位置的属性。

    • An image encoding method comprises for each of a left and a right image of a stereo pair of images, identifying, in an input image, a region of interest; generating at least two generating representations of that input image, such that one of the representations is a high field of view (FOV) representation including substantially all of the input image, and another representation is a low FOV representation having a lower FOV than the high FOV representation, and including at least the region of interest; in which the relationship between pixel resolution and image size for the high FOV representation and the low FOV representation is such that, in relation to the region of interest, the low FOV representation provides a higher amount of image detail than the high FOV representation; generating one or more multiplexed images by juxtaposing at least portions of the left and right, high FOV and low FOV representations, so as to include all of the image content of the left and right, high FOV and low FOV representations in fewer than four multiplexed images; and transmitting and/or storing the multiplexed images.
    • 图像编码方法包括用于立体图像对的左图像和右图像中的每一个,在输入图像中识别感兴趣的区域; 产生所述输入图像的至少两个生成表示,使得所述表示中的一个是包括基本上所有输入图像的高视场(FOV)表示,并且另一表示是具有比所述高的FOV更低的FOV的低FOV表示 FOV表示,并至少包括该地区的兴趣; 其中高FOV表示和低FOV表示的像素分辨率和图像大小之间的关系使得相对于感兴趣的区域,低FOV表示提供比高FOV表示更高的图像细节量; 通过并列至少部分左,右FOV和低FOV表示来生成一个或多个多路复用图像,以便在少于四个多路复用中包括左和右,高FOV和低FOV表示的所有图像内容 图片; 以及发送和/或存储多路复用图像。
