Image rectification

Image rectification is a process of making a picture straight and flat. It's like taking a crumpled piece of paper and smoothing it out so that it's perfectly flat.

Sometimes when we take a picture, the angle we take it from can make it look distorted or tilted. This can make it difficult to measure things accurately or compare different parts of the picture.

To fix this, we use special software to adjust the picture so that it looks like it was taken from straight ahead, with all the lines and angles looking like they should.

Think of it like a magic spell that makes the picture look like it was taken from a perfect angle, just like looking through a window straight ahead. This helps make sure that we can use the picture for important things, like maps and measurements, without any mistakes or errors.
