Abstract

The absorption and refraction of light by water made high-precision 3D (three-dimensional) reconstruction of underwater concrete a challenging task. This paper proposed a 3D reconstruction method combining line structured light and stereo vision. To improve the reconstruction accuracy, the epipolar constraint was introduced in the light plane calibration process to limit the fringe noise data during calibration matching. A color camera and a monochrome camera were used simultaneously to characterize the real underwater 3D environment. After matching the left and right images, the color information of the color image was retained, and the color information of the point cloud was enhanced. Finally, experiments were conducted in a water tank, and the results indicated that the 3D reconstruction error for underwater concrete was 4.48 %. Moreover, the color enhancement of the point cloud achieved the highest overall scores across the four no-reference underwater image quality assessment metrics.

基于线结构光和立体视觉的水下混凝土高精度三维重建

水对光的吸收和折射使得水下混凝土的高精度三维重建成为一项具有挑战性的任务。提出了一种线结构光与立体视觉相结合的三维重建方法。为了提高重建精度，在光平面标定过程中引入极线约束，限制标定匹配过程中的条纹噪声数据。同时使用彩色摄像机和单色摄像机对真实的水下三维环境进行表征。对左右图像进行匹配后，保留彩色图像的颜色信息，增强点云的颜色信息。最后，在水箱中进行了试验，结果表明，水下混凝土的三维重建误差为4.48%。此外，点云的颜色增强在四个无参考水下图像质量评估指标中获得了最高的总分。
