Image processing to provide stable environment recognition
An information processing system that acquires image data captured by an image capturing device; identifies a density of distribution of a plurality of feature points in the acquired image data; and controls a display to display guidance information based on the density of the distribution of the plurality of feature points.
1. An information processing apparatus, comprising:
circuitry configured to:
acquire image data of a real space by an image capturing device;
detect a plurality of feature points based on the image data;
calculate a relative position of at least one feature point from the plurality of feature points with respect to the image capturing device;
generate environment information based on the calculated relative position;
determine an un-explored area and an explored area based on the generated environment information; and
generate a direction control instruction to direct the information processing apparatus to move into the un-explored area to acquire additional environment information of the un-explored area.
2. The information processing apparatus of claim 1 , wherein the circuitry is further configured to continuously update the explored area and the un-explored area based on the acquired additional environment information.
3. The information processing apparatus of claim 1 , wherein the generated environment information includes a map.
4. The information processing apparatus of claim 3 , wherein the circuitry is further configured to detect a position of the information processing apparatus on the map.
