Abstract
To provide a distance measuring apparatus, a distance measuring method, and an imaging apparatus that can satisfactorily measure a distance. A distance measuring apparatus includes an imaging unit capable of acquiring a plurality of images having view points different from one another and a controlling unit configured to perform control to acquire the plurality of images with the imaging unit in a state in which a patterned light is projected on any region using a projecting unit disposed in a position optically conjugate to the imaging unit and measure a distance on the basis of the plurality of images acquired by the imaging unit.
Claims17
A distance measuring apparatus comprising:
- at least one processor;
- and
- a memory storing an instruction which, when the instruction is executed by the processor, causes the distance measuring apparatus to function as:
- an imaging unit capable of acquiring a plurality of images having view points different from one another;
- and
- a controlling unit configured to perform controlling to acquire the plurality of images with the imaging unit in a state in which a patterned light is projected on any region using a projecting unit disposed in a position optically conjugate to the imaging unit and measure a distance on the basis of the plurality of images acquired by the imaging unit,
- wherein the control unit controls at least one of illuminance of a patterned light projected using a projecting unit, a wavelength of the patterned light and whether the patterned light is projected or not in each of regions based on the image by the imaging unit.
A distance measuring method comprising:
- acquiring, in a state in which a patterned light is projected on any region using a projecting unit disposed in a position optically conjugate to an imaging unit, with the imaging unit, a plurality of images having view points different from one another;
- measuring a distance on the basis of the plurality of images acquired by the imaging unit;
- and
- controlling at least one of illuminance of a patterned light projected using a projecting unit, a wavelength of the patterned light and whether the patterned light is projected or not in each of regions based on the image by the imaging unit.
An imaging apparatus comprising:
- at least one processor;
- and
- a memory storing an instruction which, when the instruction is executed by the processor, causes the distance measuring apparatus to function as:
