摘要
根据双目立体视觉传感器的特点,提出了一种基于共面靶标的双目立体视觉传感器的标定方法。在不需要外部测量设备的情况下,通过共面靶标在平面上自由移动,获得靶标的标定点图像坐标,利用类似于Dr.Janne Heikkil和Dr.Olli Silven所提出来的摄像机内部参数标定模型,采用线性和非线性结合的方法对双目摄像机进行摄像机内部参数的标定。试验结果表明,标定参数与出厂参数有一定的差异,但和实际情况还是吻合的,并且标定方法操作简便,切实可行。
Based on the characteristics of the binocular stereoscopic vision sensor , a calibration method of binocular stereoscopic vision sensor based on coplanar reference target is presented. Without assistant adjustment equipment , the calibration points coordinates can be obtained by free movement of the coplanar reference target, Based on the similar model proposed by Dr. Janne Heikkilae and Dr. Olli Silven for the camera interior parameter calibrations and the method combinating linear and the non-linear data process, the cameras calibration can be implemented effectively .Experimental results show that this method is simple and practical with high precision.
