    • Provided is an image processing device that can ensure accuracy of camera calibration even if the range in which calibration markers can be installed is restricted. An image processing device (10) comprises the following: an image acquisition unit (1) for acquiring an image in which markers for calibration are captured; an edge detection unit (2) for detecting the edges of the markers in the image; a polygon generating unit (3) for estimating a plurality of straight lines on the basis of the edges and generating a virtual polygon region that is surrounded by the plurality of straight lines, the generation being carried out in the image in a region thereof including regions other than those where markers are installed; and a camera parameter calculation unit (4) for calculating camera parameters on the basis of the characteristic amount, with respect to the image, of the virtual polygon region and the characteristic amount, with respect to real space, of the virtual polygon region.
    • 本发明提供一种图像处理装置,即使能够设置校准标记的范围受到限制,也能够确保照相机校准的精度。 一种图像处理装置(10),其特征在于,包括:图像取得部(1),取得摄像了校准用标记的图像; 边缘检测单元(2),用于检测图像中的标记的边缘; 多边形产生单元(3),用于基于所述边缘估计多条直线并产生由所述多条直线包围的虚拟多边形区域,所述产生在包括区域的区域中的图像中执行 除了安装标记的那些以外; 以及相机参数计算单元(4),用于基于虚拟多边形区域相对于图像的关于虚拟多边形区域的实际空间的特征量和特征量来计算相机参数。
