Abstract
An imaging system is provided with: a first imaging apparatus (2) that captures an image of an imaging target (T, TP) that is located at a first point (P1); a second imaging apparatus (3) a focus position of which is set at a second point (P2) that is located at a forward side along a moving direction of the imaging target than the first point; and a control apparatus (6) that controls the second imaging apparatus to capture an image of the imaging target that is located at the second point on the basis of the image (200) captured by the first imaging apparatus.
Claims9
An imaging system comprising:
- a first imager that captures an image of an imaging target when the imaging target is located at a first point;
- a plurality of second imagers, a focus position of which is set at a second point that is located at a different position from the first point;
- and
- a controller that is programmed to control the second imagers to capture an image of the imaging target when the imaging target is located at the second point on the basis of the image captured by the first imager, wherein
- the controller is programmed to determine, on the basis of the image captured by the first imager, a first position that is a position of the imaging target located at the first point in the image captured by the first imager, estimate, on the basis of the first position, a second position that is a position of the imaging target in the image captured by the second imager under the assumption that the second imagers have captured the image of the imaging target after having moved from the first point to the second point, and select, on the basis of the second position, one second imager that captures the image of the imaging target when the imaging target is located at the second point.
An imaging method performed by a computer and comprising:
- obtaining an image captured by a first imager that captures an image of an imaging target when the imaging target is located at a first point;
- determining, on the basis of the image captured by the first imager, a first position that is a position of the imaging target located at the first point in the image captured by the first imager;
- estimating, on the basis of the first position, a second position that is a position of the imaging target in the image captured by a plurality of second imagers under the assumption that the second imagers have captured the image of the imaging target after having moved from the first point to a second point, wherein a focus position of the second imagers is set at the second point located at a different position from the first point;
- and
- selecting, on the basis of the second position, one second imager that captures the image of the imaging target when the imaging target is located at the second point.
A non-transitory recording medium storing a computer program executable by a computer to perform an imaging method comprising:
- obtaining an image captured by a first imager that captures an image of an imaging target when the imaging target is located at a first point;
- determining, on the basis of the image captured by the first imager, a first position that is a position of the imaging target located at the first point in the image captured by the first imager;
- estimating, on the basis of the first position, a second position that is a position of the imaging target in the image captured by a plurality of second imagers under the assumption that the second imagers have captured the image of the imaging target after having moved from the first point to a second point, wherein a focus position of the second imagers is set at the second point located at a different position from the first point;
- and
- selecting, on the basis of the second position, one second imager that captures the image of the imaging target when the imaging target is located at the second point.
