用于内窥镜色彩标准判断数据

感光元件获得的图像颜色是由光源、成像物体反射率和成像系统的光谱响应函数共同决定的，在不同光照条件下，感光元件所得到的物体图像是不断变化的，有时甚至失去了原本的色彩。感光元件所获取的图像色彩与人眼所看到的颜色由于近红外光的存在会产生偏色现象。为了去除该偏色现象，寻找合适的颜色校正参数具有重要意义。目前的偏色校正大多是针对RGB三带图像，即对RGB三通道增益进行调整达到更接近人眼色彩感知的效果。该数据知识产权用于图像原始色彩的输出，将检测到图像的RGB三通道的值进行判断调整，导出最接近原始色彩的图像。对内窥镜1进行图像采样，提取出RGB三个通道值，通过参数调节改变采样图像的色彩。如标准样板图像的RGB为（216,228,320），对采样到的RGB进行分割，得到R值、G值、B值，并通过与样板图像标准RGB值的差值计算得到dR、dG、dB。当dR、dG、dB的绝对值同时小于10时，输出结果为OK，否则输出结果为NG。当输出结果为OK时，判断当前图像为最接近原始色彩。

The color of an image captured by an image sensor is jointly determined by the light source, the reflectance of the imaged object, and the spectral response function of the imaging system. Under different lighting conditions, the images of objects captured by the image sensor change continuously, and sometimes even lose their original color hues. The image colors captured by the image sensor will have color cast compared to the colors perceived by the human eye, due to the presence of near-infrared light. To eliminate this color cast, it is of great significance to find appropriate color correction parameters. Most current color cast correction methods target RGB tri-band images, i.e., adjusting the gains of the three RGB channels to achieve results closer to human color perception. The intellectual property of this dataset is designed for outputting the original colors of images: it detects and adjusts the RGB three-channel values of the captured image, and exports the image that most closely matches the original color. Perform image sampling on Endoscope 1, extract the three RGB channel values, and adjust the color of the sampled image via parameter tuning. For example, if the RGB values of the standard reference image are (216, 228, 320), separate the sampled RGB values to obtain the R, G, and B channel values, then calculate dR, dG, and dB based on the differences from the standard RGB values of the reference image. When the absolute values of dR, dG, and dB are all less than 10, the output result is OK; otherwise, the output result is NG. When the output result is OK, the current image is determined to be the closest to the original color.
