What is stadiametric rangefinding?

Stadiametric rangefinding is a method of estimating the distance of a target using known measurements of that target. It is commonly used in photography, surveying, and military applications.

In stadiametric rangefinding, the user takes note of the width or height of the target in the field of view, and compares it to a known measurement. This can be done by using a reticle or scale in the viewfinder or on the lens of the device. By knowing the distance from the target, the user can use trigonometry to estimate the distance of the object.

Stadiametric rangefinding can be less accurate than other methods such as laser rangefinders, but it is often faster and simpler to use. It also does not require expensive equipment and can be used in low light conditions.

However, stadiametric rangefinding does require a good eye for distance estimation and can be affected by variables such as atmospheric conditions and the skill of the user. It is important to regularly practice and calibrate the equipment for optimal results.
