Where can I find the pixel size of my camera?

Project Creation

Correlator3D should automatically detect your camera and retrieve its pixel size from its database. However, if you need to manually set this value, you can find the pixel size of a camera on the camera manufacturer website or reference websites like "Digital Camera Database" (https://www.digicamdb.com/). Note that the pixel size is sometimes referred as "pixel pitch".

The pixel size can also be derived from the the size of the sensor (or CCD size) by the number of pixels for the height and width, respectively.

 

Example:

Sensor size = 23.7 x 15.7 mm

Image size = 4928 x 3264 pixels

Pixel size = 23.7 / 4928 * 1000 = 4.81 µm (or 15.7 / 3264 * 1000 = 4.81 µm)

An average can be done in between the height and width value if they differ.

Note that the pixel size is expressed in micrometers in Correlator3D.
