: Studies have shown that AI-assisted virtual rulers are significantly more accurate than human endoscopists. For example, systems like ENDOANGEL-CPS have achieved an 89.9% accuracy rate in estimating polyp size compared to just 54.7% for human operators.
At its core, a virtual ruler is a software-based tool that estimates the physical dimensions—such as length, width, diameter, or depth—of real-world objects using digital sensors. Unlike a wooden or plastic ruler, it does not require physical proximity to the object. These tools generally fall into three categories: virtual ruler
