Description
上記課題を解決するために、この発明は以下の手段を提案している。
本発明の一実施態様にかかる内視鏡装置は、光の明暗パターンが投影された被検物のパターン投影画像を用いて前記被検物の計測を行う内視鏡装置であって、挿入部と、前記挿入部の先端部に設けられ、前記被検物の画像を取得する撮像部と、前記撮像部の観察視野を照明する照明光を発する照明部と、前記被検物に前記明暗パターンを投影するパターン投影部と、を備え、前記挿入部の先端面には、前記撮像部に前記被検物の像を結像させる対物光学系と、前記照明光を出射する１つ以上の照明窓と、前記パターン投影部から前記被検物へ前記明暗パターンを投影する１つの投影窓と、が設けられ、前記パターン投影部は、前記明暗パターンを生成するパターン生成部を備え、前記明暗パターンは、明部と暗部とが繰り返し交互に配置された分布パターンであることを特徴とする。
In order to solve the above problems, the present invention proposes the following means.
An endoscope apparatus according to an embodiment of the present invention is an endoscope apparatus that performs measurement of the test object using a pattern projection image of the test object on which a bright and dark pattern of light is projected, and includes an insertion unit An imaging unit that is provided at a distal end of the insertion unit and acquires an image of the test object, an illumination unit that emits illumination light that illuminates an observation field of view of the imaging unit, and the light-dark pattern on the test object An objective optical system that forms an image of the test object on the imaging unit, and at least one illumination that emits the illumination light A window and one projection window for projecting the light / dark pattern from the pattern projection unit onto the test object, the pattern projection unit including a pattern generation unit that generates the light / dark pattern, and the light / dark pattern The light and dark areas are arranged alternately and repeatedly. Characterized in that it is a distribution pattern.
