An image processing device (10) has an image interface (18), a memory (19), and a controller (20). An image interface (18) acquires a captured image. A memory (19) stores positions of each of a plurality of specific feature points in a world coordinate system and reference positions of each of the plurality of specific feature points. The controller (20) detects a plurality of specific feature points in the captured image. The controller (20) recalculates the correction parameter when the position in the captured image of a feature point having a predetermined ratio or more among the plurality of feature points changes with respect to a reference position.

    图像处理装置(10)具有图像接口(18)、存储器(19)、以及控制器(20)。图像接口(18)获取拍摄图像。存储器(19)存储多个特定的特征点各自的在世界坐标系中的位置和多个特定的特征点各自的基准位置。控制器(20)检测拍摄图像中的多个特定的特征点。控制器(20)在多个特征点中的规定比例以上的特征点在拍摄图像中的位置相对于基准位置发生变化的情况下,重新计算校正参数。
