Pixel Resolution calculator
Object-space resolution from sensor pixel pitch.
Category: Imaging
Formula: GSD = p·(u − f)/f (≈ p·u/f for u ≫ f)
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Pixel pitch | p | µm | 3.45 |
| Distance | u | mm | 1000 |
| Focal length | f | mm | 25 |
Result with the default inputs
- Object px size: 134.55 µm
- Object px size: 0.1346 mm
Open it with your own values: put each input in the address as a parameter, for example /calculators/pixel-resolution?p=3.45. A unit other than the listed one goes in <parameter>_unit.
