摘要 |
Attempts to achieve a higher resolution and a higher frame rate of a distance image when a distance to an object within a target space is estimated using the TOF method would cause CCD saturation due to shot noise or environment light, and lower distance precision. A distance estimation apparatus illuminates an object with illumination light for distance estimation emitted from a light source that can emit light (electromagnetic wave) having a predetermined illumination frequency, receives reflected light of the illumination light, obtains information about the distance from the apparatus to the object, generates distance image data based on the distance information, extracts edge information of a color image formed using a visible light component obtained in synchronization with the reflected light, and corrects distance information of a target part of the distance image using distance information of a neighboring part of the target part based on the edge information. |
