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.

摘要： Conventionally, there has been a danger that CCD saturation may occur because of the influence of the shot noise and the environment light if a higher resolution of a distance image showing the distance to an object present in a target space and a higher frame rate are achieved when the distance image is estimated by the TOF method, and the distance accuracy may degrade. An emission frequency selecting unit (7) receives light (S2) reflected from the object when a light source does not emit light and selects illumination light (S1) having an emission frequency insusceptible to the environment light according to the frequency analysis of the reflected light (S2). An image creating unit (6) selects a light source emitting the illumination light having the optimum emission frequency from among prepared light sources (9A to 9N), receives reflected light of the illumination light from the selected light source, and creates the distance image showing the distance to the object. The environment light can be mitigated during light reception, and the noise influence on the distance accuracy can be mitigated when a light-receiving element unit (2) exhibiting higher resolution is used.
