ことを特徴とするレンジフアインダ。 In a range finder using a coded pattern projection method, a projector equipped with a multi-slit pattern that generates multi-slit light and a first filter that generates reference slit light having a wavelength distribution different from that of the multi-slit light; Multi-slit light including the reference slit light is projected onto the measurement object from this projector, and an optical system receives an image of the reflected slit light from the measurement object; a second filter that extracts an image of only the reference slit light from the image of one reflected slit light separated by the half mirror; and only the reference slit light that has passed through the second filter. The first image of
an image sensor, a second image sensor that captures an image of the other reflected slit light separated by the half mirror, and a coordinate of the slit from the two images captured by the first and second image sensors. A range finder characterized in that it is configured to include an image processing device that performs image processing to obtain the range finder.
