双目立体视觉传感器的现场标定技术

On-line Calibration Technique of Binocular Stereoscopic Vision Sensor

双目立体视觉传感器在机器视觉和三维测量中有着广泛的应用。其中测量精度是一个很重要的因素,尤其是在三维测量中,高测量精度的要求使得传感器的标定显得尤为重要。该文提出了一种双目立体视觉传感器的现场标定方法,不仅提高了标定精度,还避免了离线标定中大量的重复性劳动,同时也研究了摄像机镜头畸变的问题。实验结果表明,此方法能够得到满意的标定精度。

It is widely applied in robot vision and3D measure for binocular stereoscopic vision sensor.Because measure precision is an important factor in3d measure,the sensor calibration become very important for high measure precision.An on-line calibration method of binocular stereoscopic vision sensor is proposed in this paper,it not only improves the calibration precision,but also avoids unnecessary work.At the same time we study the lens aberration.The experimental results show that we can get the satisfactory calibration precision by using this method.
