Abstract: An information processing method and information processing device helps drivers easily recognize the environment outside a vehicle. The method includes acquiring the current spatial position of a camera and its shooting range, constructing a three-dimensional scene of the shooting range and setting the display property of this three-dimensional scene as transparent, acquiring a two-dimensional view of this three-dimensional scene from the view point of the camera based on the three-dimensional scene and the distribution data of interest points within the shooting range, wherein the two-dimensional view includes the annotation of an interest point whose position in the two-dimensional view corresponds to the position of the interest point of the current frame captured by the camera, adjusting the size of the two-dimensional view to match it with the size of the frame captured by the camera, and outputting the frame superposed with the two-dimensional view.
