我如何将坐标x y从图像转换为经度/纬度和背面？

Question

我有城市的图像，如果我知道3点像

我可以获得我添加到图像的点的经度/纬度

Point1XRelative =“ - 18340651.0304568”;

Point1YRelative =“14945227.3984772”;

Point2XRelative =“ - 3960915.94162438”;

Point2YRelative =“ - 7933119.6827411”;

Point3XRelative =“4901426.10152285”;

Point3YRelative =“13585796.8781726”;

Point1XWorld =“53.1186547”;

Point1YWorld =“29.2392344”;

Point2XWorld =“52.6341388”;

Point2YWorld =“29.7438198”;

Point3XWorld =“53.0900105”;

Point3YWorld =“30.0548051”;

我有algrithm只能转换为平面，当我从long / lat转换为x y时，它们会转换为offset。 请告诉我如何解决这个问题。

它还取决于缩放级别。我想你会找到你需要的东西here。
