Abstract: A distance information generation apparatus obtains a measurement depth image that expresses a measurement result for a distance to an object and a color image captured at a corresponding field of view. The measurement depth image is upsampled by a predetermined technique to generate a candidate depth image. On the basis of a result of analyzing the color image, a reflection characteristic for the object, and information regarding a relative motion between an image capturing apparatus and the object, a reliability image, in which a reliability for a distance value expressed by the candidate depth image is set for each pixel, is generated. A distance value having a high reliability is read out for each pixel from the candidate depth image, whereby an output depth image is generated.

Abstract: Pulsed light emitted from a light emitter of a TOF sensor at an intensity is divided into light that is reflected by an object having transmissivity and reaches a light receiver at an intensity and light that passes through the object and reaches an object at an intensity. The latter is reflected by the object at an intensity, partly passing through the object to reach the light receiver at an intensity. A local maximum point is detected in a change in a degree of photons observed by the light receiver, to acquire both distances to the object and the object.

Abstract: Irradiation light from a sensor is separated into transmission light and reflected light through a one-way mirror to reach objects that are present in a plurality of directions. The one-way mirror concentrates the reflected light on the sensor. A position information acquisition device detects a local maximum point in a change in a degree of photons observed by the sensor, thereby acquiring path lengths of light to objects to generate position information on the basis of the position and the posture of the one-way mirror from the sensor.
