Information processing apparatus, information processing method, and computer-readable recording medium

An information processing apparatus according to an embodiment includes a control unit (corresponding to an example of a controller). The control unit performs a posture estimation process to estimate a posture of the in-vehicle camera based on an optical flow of a feature point in a region of interest set in an image captured by the in-vehicle camera. When the in-vehicle camera is installed in a first state, the control unit performs a first attitude estimation process using a first region of interest set in a rectangular shape; and when the in-vehicle camera is mounted in the second state, the control unit performs a second attitude estimation process using a second region of interest set according to the road surface shape. 根据实施例的信息处理装置包括控制单元(对应于"控制器"的示例)。控制单元执行姿态估计处理，以基于在车载相机捕获的图像中设置的感兴趣区域中的特征点的光流来估计车载相机的姿态。当车载相机以第一状态安装时，控制单元使用设置为矩形形状的第一感兴趣区域来执行第一姿态估计处理；并且当车载相机以第二状态安装时，控制单元使用根据路面形状设置的第二感兴趣区域来执行第二姿态估计处理。
