商用现成数码相机是一种廉价且易于使用的工具，如果以原始格式捕获图像并对其进行处理，使其与场景辐射保持线性关系，则可用于定量获取科学数据。在这里，我们描述了使用彩色相机进行一致数据采集所需的图像处理步骤。此外，我们提出了一种特定于场景的颜色校准方法，当场景中包含在标准颜色校准目标的色域中不能很好地表示的颜色时，该方法可以提高颜色捕获的精度。我们展示了所提出的方法在生物医学工程、艺术品摄影、感知科学、海洋生物学和水下成像领域的应用。
Commercial off-the-shelf digital cameras are inexpensive and easy-to-use instruments that can be used for quantitative scientific data acquisition if images are captured in raw format and processed so that they maintain a linear relationship with scene radiance. Here we describe the image-processing steps required for consistent data acquisition with color cameras. In addition, we present a method for scene-specific color calibration that increases the accuracy of color capture when a scene contains colors that are not well represented in the gamut of a standard color-calibration target. We demonstrate applications of the proposed methodology in the fields of biomedical engineering, artwork photography, perception science, marine biology, and underwater imaging.
