Abstract
(EN) A projection device (10) according to an aspect of the present invention is to be used on building sites. The projection device (10) comprises: a projection unit (21) that projects images on an image-projected plane (110); a distance measurement unit (24) that measures the distance to the image-projected plane (110); a rotation driving unit (23) that rotates the projection unit (21) and the distance measurement unit (24); an angle measurement unit (22) that measures the rotation angle of the rotation driving unit (23); and a data processing unit (25a) that corrects the images projected from the projection unit (21). At least one or both of the distance measurement unit (24) and the projection unit (21) are offset from the center line of the rotation axis of the rotation driving unit (23). The data processing unit (25a) corrects the images by use of the distance measured by the distance measurement unit (24) and the rotation angle measured by the angle measurement unit (22).
(FR) Un dispositif de projection (10) selon un aspect de la présente invention est destiné à être utilisé sur des chantiers de construction. Le dispositif de projection (10) comprend : une unité de projection (21) qui projette des images sur un plan de projection d'image (110) ; une unité de mesure de distance (24) qui mesure la distance au plan de projection d'image (110) ; une unité d'entraînement en rotation (23) qui fait tourner l'unité de projection (21) et l'unité de mesure de distance (24) ; une unité de mesure d'angle (22) qui mesure l'angle de rotation de l'unité d'entraînement en rotation (23) ; et une unité de traitement de données (25a) qui corrige les images projetées par l'unité de projection (21). L'unité de mesure de distance (24) et/ou l'unité de projection (21) sont décalées par rapport à la ligne centrale de l'axe de rotation de l'unité d'entraînement en rotation (23). L'unité de traitement de données (25a) corrige les images en utilisant la distance mesurée par l'unité de mesure de distance (24) et l'angle de rotation mesuré par l'unité de mesure d'angle (22).
(JA) 本発明の一態様に係る投影装置(10)は、建築現場で使用される投影装置である。投影装置(10)は、被投影面(110)に画像を投影する投影部(21)と、被投影面(110)までの距離を計測する測距部(24)と、投影部(21)と測距部(24)とを回転させる回転駆動部(23)と、回転駆動部(23)の回転角度を計測する測角部(22)と、投影部(21)から投影する画像を補正するデータ処理部(25a)とを備える。測距部(24)と投影部(21)とは、少なくとも一方、または両方が回転駆動部(23)の回転軸の中心線上から外れて設けられている。データ処理部(25a)は、測距部(24)で計測された距離と、測角部(22)で計測された回転角度とを用いて画像を補正する。
