An information processing apparatus that executes processing for creating an environmental map includes a camera that photographs an image, a self-position detecting unit that detects a position and a posture of the camera on the basis of the image, an image-recognition processing unit that detects an object from the image, a data constructing unit that is inputted with information concerning the position and the posture of the camera and information concerning the object and executes processing for creating or updating the environmental map, and a dictionary-data storing unit storing dictionary data in which object information is registered. The image-recognition processing unit executes processing for detecting an object from the image with reference to the dictionary data. The data constructing unit applies the three-dimensional shape data to the environmental map and executes object arrangement on the environmental map.
