In order to match coordinates between space and infrared image without color and texture in the calibration process, a design criterion for one-dimensional objects was presented. When one-dimensional objects met a given ratio of those objects, the corresponding coordinates could be acquired by the pixels' distance. The design reliability was theoretically proved. The experiment shows that one-dimensional objects satisfying the design criterion are easy to operate and convenient to match, so infrared camera calibration can obtain very high accuracy.%在标定过程中针对红外摄像机组缺乏颜色和纹理信息而无法完成标定点空间和图像坐标匹配,提出一维标定物设计准则.当一维标定物的标记点相互距离满足给定比例关系,通过标记点的像素距离作为判断条件,对标定的标记点空间和图像位置进行匹配.理论上证明了设计准则的可靠性.实验表明:满足设计准则的一维标定物操作简单、匹配方便,标定后红外摄像机组参数精度高.
