How Camera Distance Calculation Works
This calculator uses the principle of perspective projection in computer vision. The formula calculates distance based on the relationship between an object’s actual size, its apparent size in pixels, and the camera’s field of view (FOV).
Calculation Formula
Distance = (Real Object Height × Image Width) / (2 × Perceived Pixel Height × tan(FOV/2))
| Phone Model | Horizontal FOV | Typical Image Width |
|---|---|---|
| Google Pixel 7 | 65° | 4032px |
| Samsung Galaxy S23 | 63° | 4000px |
| OnePlus 11 | 68° | 4096px |
Factors Affecting Measurement Accuracy
- Camera lens distortion
- Object alignment in frame
- Precision of FOV values
- Measurement of pixel height
- Camera sensor size
- Object orientation
FAQ
How accurate is this calculation?
Accuracy depends on precise FOV values and proper object measurement. Typical error margins range 5-15% in ideal conditions.
Can I use this for vertical measurements?
Yes, but ensure you’re using vertical FOV instead of horizontal FOV in the calculation.
