| 摘 要： | 提出了一种由单幅图像得到目标物体深度信息的方法。该方法通过计算机图像处理技术获取相关的图像信息,再结合光学成像原理将所用数码相机的实际物理焦距和图像中目标物体的大小均效到135相机的标准上,由计算机编程计算得出目标与测量系统之间的相对位置关系。介绍了测量原理,推导出了参数计算公式。实验表明,此系统测量精度满足工程测量要求。

| Abstract: | A field of 3 - D space position has been researched by using digital camera and a method using which we can get distance information of the target object based on single image has been described in this paper. Firstly, we obtained information of image by digital image processing. Secondly, we make the focus of the digital camera and the size of the target to be equivalent to the standard of 135 camera. Finally, the relative position of the target and the measuring system can be gained by using computer program. The principle of the measurement and the parameter calculating equation is featured. The experiment results shown a good agreement and the accuracy of measurement fulfilled the requirement of engineering. |
