遥感,通俗来说就是对卫星、飞机、无人机和地面移动平台所拍摄像片的一门处理技术与方法。采用几何学、数据处理和人工智能等手段,回答“从何处拍摄”“拍到了什么”以及“所拍物体的属性”等问题。光的世界:遥感的诞生西汉文学家匡衡小时候很穷,没钱买蜡烛。他在墙壁上挖了一个小孔,邻居家蜡烛的光射过来,可供他晚间读书。匡衡可能会注意到,书上会产生蜡烛的倒影。这种由光的直线传播带来的现象称为小孔成像,所对应的三维世界到二维平面的映射,称为透视变换。目前一般认为,文艺复兴初期的意大利建 Remote sensing, in short, is a processing technique and method for taking pictures of satellites, aircraft, drones and ground mobile platforms. Use geometry, data processing, and artificial intelligence to answer questions such as where to shoot, what to photograph, and the properties of the object you are filming. The world of light: the birth of remote sensing Kuang Heng, a Western-born writer, was poor and had no money to buy a candle. He dug a hole in the wall and the light of the neighbor’s candle shone for his evening study. Kuang Heng may notice that the candle will be reflected in the book. This phenomenon caused by the linear transmission of light called pinhole imaging, the corresponding mapping of the three-dimensional world to the two-dimensional plane, called the perspective transformation. Currently generally believed that the early Renaissance Italy built
