Abstract
A jig holds an imaging apparatus including a plurality of cameras with different optical axis orientations and a chart including a plurality of planes with different angles and changes the orientation of the imaging apparatus relative to the chart. A calibration apparatus obtains camera parameters of the imaging apparatus by sequentially acquiring captured images captured by adjacent cameras when these cameras have obtained predetermined fields-of-view relative to the chart and extracting images of feature points of chart patterns.
