Abstract

Abstract Main aim of the paper is to use a single non-metric camera to support the determination of the position of. Authors propose to use the existing infrastructure of CCTV cameras mounted on bridges and wharves to determine the position of inland waterway vessels. Image from cameras giving the pixel coordinates of moving object is transformed to the geodetic data domain using a modified projective transformation method. Novel approach is to use of Sequential Projection Transformation (SPT) which additionally uses virtual reference points. The transformation coefficients calculated using the virtual points are used to determine the position of the vessels and are also simultaneously used to calibrate the industrial camera. The method has been verified under real conditions, and the results obtained are average 30% more accurate compared to the traditionally used projective transformation using a small number of real points.

基于工业相机影像的内河航运不完全时空数据改进方法——以西奥得河为例

摘要本文的主要目的是利用单个非度量相机来支持物体的位置确定。作者建议利用现有的安装在桥梁和码头上的闭路电视摄像机基础设施来确定内河船舶的位置。利用改进的射影变换方法，将给出运动物体像素坐标的摄像机图像转换为大地测量数据域。一种新颖的方法是利用序列投影变换(SPT)，在此基础上增加虚拟参考点。利用虚拟点计算的变换系数用于确定容器的位置，同时也用于校准工业相机。该方法在实际条件下进行了验证，得到的结果比使用少量实点的传统投影变换平均提高了30%。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
