摘要
基于机器视觉的无损检测是植物生长建模的关键技术之一,对图像采集系统进行标定是实现无损检测的基本步骤。目前,摄像机标定的方法有传统标定方法、主动视觉标定法、自标定方法等。为此,对现有标定方法分别进行了讨论与比较,结果表明,传统线性标定法可以满足农作物无损检测的要求。
The measurement of plants based on machine vision system is one of most important parts of plants simulation. The calibration of the image acquisition system is a basic step for nondestructive detection. The methods for camera calibration can be divided into traditional calibration techniques, active vision based camera calibration techniques, and self-calibration techniques. We discussed the above-mentioned methods and compared the differences between them. The result showed that the traditional lineal calibration method could be applied in nondestructive measurement of plants.
