Question: Describe the benchmark technique for estimating a distance?
A benchmark technique for estimating a distance is to use a reference object of known size and compare it with the target object. For example, if we know the height of a person standing near a building, we can use the ratio of their heights to estimate the distance from the camera to the building. This technique is based on the principle of similar triangles, which states that two triangles are similar if they have the same angles and proportional sides. The advantage of this technique is that it does not require any special equipment or calibration, and it can be applied to any object that has a known size. The disadvantage is that it relies on the accuracy of the reference object and the assumption that the objects are aligned along the same plane.
