水下目标彩色三维重建方法研究

Research on Underwater Target Color Three-dimensional Reconstruction Mehod

针对传统的线结构光扫描法无法获得水下目标彩色信息的问题,提出了一种RGB激光扫描方法,设计了水下目标三维扫描系统。采用RGB三基色激光合并成一束白光线光源,经过标定板标定后,对水下目标进行扫描。CCD相机采集目标彩色信息,通过计算机算法,实现了水下目标的三维重建并复原了目标的彩色信息。重建结果表明,水下目标颜色再现真实准确,此方法计算量小、扫描速度快、效率高,可以实时获取并重建水下目标的彩色三维信息。

The traditional laser line scanning method cannot acquire the color information of underwater targets. A red green blue （RGB） laser scanning method is proposed to design a 3D scanning system for underwater targets. RGB three primary colors laser combined into a beam of white light source, after calibrated by the calibration board, the underwater targets are scanned. The CCD camera is used to collect the color information of the targets, and the 3D reconstruction of the underwater targets is realized and the color information of the targets is obtained through computer algorithm. Reconstruction results show that the color reproduction of under- water targets is real and accurate. The method has the advantages of small computation, fast scanning speed and high efficiency. The 3D color information of underwater targets is acquired and reconstructed in real time.
