Depth Estimation
Definition
Depth estimation determines approximate distances or the relative depth of image points from camera images.
The estimation of distance or relative depth of image points from one or more camera views.
Simply explained
From one or more images, it is estimated which areas are closer and which are farther away.
Why it matters in practice
The term helps to select, develop, evaluate AI systems in a well-founded manner and realistically assess their technical risks.
Example from business
A warehouse operation estimates distances for collision warnings and validates them with real measurements.
Limits and pitfalls
- Monocular depth can only be relative or scale-ambiguous; light, transparent surfaces, and domain shifts cause errors.
Origin & history
Depth was classically estimated stereoscopically; neural monocular methods became widespread from 2014 onwards.
Use in mid-sized companies
- Possible example: A warehouse operation estimates distances for collision warnings and validates them with real measurements.
