Abstract
An image processing apparatus includes an acquisition unit to acquire a captured image obtained by capturing, by an image capturing unit, a target object to which a pattern has been projected. An adjustment unit adjusts, based on the pattern in the acquired captured image, at least one of a first parameter for controlling brightness of the pattern projected from a projection unit configured to project the pattern, and a second parameter for controlling an exposure amount of the image capturing unit.
Claims15
An image processing apparatus comprising:
- an acquisition unit configured to acquire a captured image obtained by capturing, by an image capturing unit, a target object to which a pattern has been projected;
- and
- an adjustment unit configured to adjust, based on the pattern in the acquired captured image, at least one of a first parameter for controlling brightness of the pattern projected from a projection unit configured to project the pattern, and a second parameter for controlling an exposure amount of the image capturing unit.
An image processing apparatus comprising:
- an acquisition unit configured to acquire a captured image obtained by capturing, by an image capturing unit, a target object to which a pattern has been projected;
- a unit configured to specify a maximum pixel value among pixel values of respective pixels referred to detect a position of the pattern from the captured image, and to acquire a distribution of the maximum pixel value;
- and
- an adjustment unit configured to adjust, by using the distribution, one of (i) a first parameter for controlling brightness of the pattern projected from a projection unit configured to project the pattern, and (ii) a second parameter for controlling an exposure amount of the image capturing unit.
An image processing method to be performed by an image processing apparatus, the method comprising:
- an acquisition step of acquiring a captured image obtained by capturing, by an image capturing unit, a target object to which a pattern has been projected;
- and
- an adjustment step of adjusting, based on the pattern in the acquired captured image, at least one of a first parameter for controlling brightness of the pattern projected from a projection unit configured to project the pattern, and a second parameter for controlling an exposure amount of the image capturing unit.
