遥感envi仿写今天是实习的第一天主要是对影像波段、辐射亮度反射率的计算。在刚开始的时候我遇到了文件打开的问题在更换路径以后就顺利打开了。实习的问题前三个主要是关于影像地物识别和判读的它运用了我们在大二上学期学的物体波段属性知识。不同波段下地物会呈现出不同的颜色。题目中还询问了呈现颜色的原因我当时也是思考了一段时间才写出来。中间的三道题考察了我们对于影像数据的判读。在一幅影像的最开始属性框里面显示

Today is my first day of internship, mainly focusing on the calculation of image bands, radiance, and reflectivity. At the beginning, I encountered problems opening files, but after changing the file path, I was able to open them smoothly. The first three internship tasks mainly focused on object recognition and interpretation in images, which applied our knowledge of object band properties learned in the second semester of our sophomore year. Different objects will appear in different colors under different bands. The task also inquired about the reasons for the color presentation, which I had to think about for some time before writing the answer. The middle three tasks tested our interpretation of image data. The number of bands is displayed in the attribute box of an image, and there is also the interpretation of the folded statistics chart, which are the most basic operations in ENVI. The sixth task was about image correlation, which involves combining two bands of images through the attribute box. After the combination, we can also obtain the DN values of each band. However, I spent a long time looking for the Forbidden City, but eventually found it. Overall, the first internship was a review of our previous knowledge, although I just finished the remote sensing software exam, but I have forgotten some knowledge. I hope to skillfully apply the previous knowledge in the future internship
