深度相机越来越多地用于水下环境中的研究和工业。然而,已经在空气中校准的相机在放置在水下时在深度测量中明显不准确,并且很少有研究来探索预先存在的深度校准方法及其在水下环境中的有效性。我们在一台低成本的商业深度相机上使用了四种校准方法,包括水中和水中。对于这些方法中的每一种,我们将预测的物体到相机的距离和长度与手动测量值进行比较,以获得深度和长度精度的指示。我们的研究结果表明,在空气中校准的标准方法在很大程度上是无效的水下校准和自定义校准技术是必要的,以达到更高的精度。
Depth cameras are increasingly used in research and industry in underwater settings. However, cameras that have been calibrated in air are notably inaccurate in depth measurements when placed underwater, and little research has been done to explore pre-existing depth calibration methodologies and their effectiveness in underwater environments. We used four methods of calibration on a low-cost, commercial depth camera both in and out of water. For each of these methods, we compared the predicted distance and length of objects from the camera with manually measured values to get an indication of depth and length accuracy. Our findings indicate that the standard methods of calibration in air are largely ineffective for underwater calibration and that custom calibration techniques are necessary to achieve higher accuracy.
