    • A guidance prompt used for guidance for a guide branch point ahead of a movable object is selected from among a plurality of potential guidance prompts, based on whether a distance from a guidance starting point where guidance starts to a guidance ending point by which guidance is required to be finished is greater than a distance traveled by the movable object while guidance is being spoken. The selected guidance prompt is then set as the guidance prompt for the guide branch point, and guidance for the guide branch point by the set guidance prompt is performed when the movable object reaches the guidance starting point associated with the set guidance prompt.
    • 基于从引导开始的引导开始点到需要引导的引导结束点的距离,从多个潜在引导提示中选择用于引导可移动对象之前的引导分支点的引导提示 在被引导时,要完成的距离大于可移动物体行进的距离。 然后将选择的引导提示设置为引导分支点的引导提示,并且当可移动对象到达与设置的引导提示相关联的引导开始点时,通过设置引导提示引导引导分支点。

    • An object tracking apparatus is provided that enables the possibility of erroneous tracking to be further reduced. An object tracking apparatus (300) is an apparatus that tracks the position of an object displayed in video using a particle filter, and has: a feature calculation section (340) that generates a plurality of particles indicating candidates for the position of the object, and calculates a feature of an image of the object and features of images of the particles; a likelihood calculation section (350) that calculates, for each particle, the likelihood of that particle being the position of the object from similarity between a feature of an image of that particle and a feature of an image of the object; a position estimation section (360) that estimates the position of the object based on the calculated particle likelihood; and a likelihood correction section (390) that performs likelihood correction when there are a plurality of objects and a plurality of positions estimated in correspondence to these overlap.
    • 提供了一种能够进一步减少错误跟踪的可能性的对象跟踪装置。 物体跟踪装置(300)是使用粒子滤波器跟踪在视频中显示的对象的位置的装置,具有:特征计算部(340),其生成表示对象的位置的候选的多个粒子, 并计算对象的图像的特征和粒子的图像的特征; 对于每个粒子,对于该粒子的图像的特征与对象的图像的特征之间的相似度,计算该粒子的位置的可能性的似然度计算部(350) 位置估计部(360),其基于所计算的粒子似然率来估计所述对象的位置; 以及当存在多个对象时执行可能性校正的似然性校正部(390),并且与这些对应度对应地估计的多个位置。

    • An information display apparatus which improves the position accuracy of superimposed displays. In a navigation apparatus, a position relationship detection unit acquires, as position information, the relationship between the position of the vehicle and the actual position where an object to be displayed in a superimposing manner should exist in the landscape, a vehicle attitude detection ECU acquires the attitude information of the vehicle, and a facial orientation recognition ECU acquires the facial orientation information of the driver. A display position determining unit determines the display position of the object on an HMD and HUD based on the position information, attitude information, and facial orientation information, and a display image generation unit performs control so as to display the object at the display position at the HMD, etc.
    • 一种提高叠加显示器的位置精度的信息显示装置。 在导航装置中,位置关系检测单元获取作为位置信息的车辆的位置与重叠显示对象的实际位置之间的关系应存在于风景中,车辆姿态检测ECU获取 车辆的姿势信息和面部姿态识别ECU获取驾驶员的面部姿态信息。 显示位置确定单元基于位置信息,姿态信息和面部方向信息来确定HMD和HUD上的对象的显示位置,并且显示图像生成单元执行控制以便在显示位置处显示对象 HMD等
