森林冠层半球图像是由带有鱼眼镜头的数码相机在冠层的底部由下向上拍摄而成。对彩色的森林冠层半球图像，运用RGB彩色模型，通过对不同阈值的尝试，最终验证了在RGB彩色模型下的分割。本方法计算速度快，精度高，为研究森林冠层的生长状况，快速有效地获取叶面积指数及冠层孔隙度提供了新途径。

Forest canopy hemisphere image is shot by a digital camera with a fisheye lens at the bottom of the cano-py from the bottom up.By using RGB color model with different threshold values, the color forest canopy hemi-spherical images were tested under the segmentation of RGB color model.The results showed it had fast computing speed with high precision , and it will provide a new way for accessing the leaf area index , canopy porosity and growth conditions for the forest canopy .
