Abstract
An image processing apparatus (client apparatus) includes an obtaining unit configured to obtain a fisheye image captured by an imaging unit including a fisheye lens, a detection unit configured to detect an object having a specific size as a detection target object from the fisheye image obtained by the obtaining unit, and a setting unit configured to set a size of the detection target object to be detected by the detection unit based on a distance from a reference position in the fisheye image and a height at which the imaging unit is installed.
Claims17
An image processing apparatus comprising:
- an obtaining unit configured to obtain a fisheye image captured by an imaging unit including a fisheye lens;
- a detection unit configured to detect an object in the fisheye image obtained by the obtaining unit;
- a setting unit configured to set, based on a distance from a reference position in the fisheye image to a given position in the fisheye image, a minimum size corresponding to the given position, wherein the minimum size is set to decrease as the distance increases;
- and
- an output unit configured to output a detection result by the detection unit, wherein a given object detected at the given position in the fisheye image is excluded from the detection result, if a size of the given object detected at the given position is smaller than the minimum size corresponding to the given position.
