Abstract

See full text

An information processing apparatus includes an irradiation unit to irradiate a measurement target with a measurement pattern for distance measurement. An imaging unit obtains a captured image including the irradiated measurement target. A first detection unit detects first and second regions from the captured image. The first region includes a first portion of the measurement target that reflects a greater amount of light toward the imaging unit. The second region includes a second portion of the measurement target that reflects a lesser amount of light toward the imaging unit. A second detection unit detects, from the measurement pattern, a first region with which the first portion is irradiated and a second region with which the second portion is irradiated. A generation unit generates a measurement pattern that has different amounts of irradiation light depending on regions. A distance to the measurement target is derived using an obtained captured image.
