| 摘 要： | 田间条件下,比较了拍摄高度、角度、光强和分辨率对所获得的图像颜色参数的影响,分析了图像颜色参数与草坪草地上部全氮含量的相关性,结果表明:数字图像颜色参数中灰度(H)和绿红光比值(G/R)与草坪地上部植株全氮含量相关性最好,达极显著水平;自然光照条件下,拍摄高度、角度、光强和分辨率对所获得的图像颜色参数H和G/R均没有影响.

| Abstract: | The effects of height,angle,light intensity and differentiation rate of photography on image color parameters were compared in the filed condition.The correlation between image color parameters and nitrogen content of the aboveground turfgrass were analyzed.The results showed that gray degree(H) and green-red ratio(G/R) has significantly correlated with the nitrogen content.The height,angle,light intensity and differentiation rate of photography had no influence on H and G/R. |
