Nowadays, every mobile phone has a front-facing camera, and everyone takes selfies with the front-facing camera. But selfie photos are always less natural than photos taken by the rear camera at a distance. In fact, this involves an optical knowledge, lens distortion.
Our normal cameras have lens distortion correction, but due to the close distance between the person and the camera lens when taking a selfie, lens distortion will still affect the final photo effect.
In order to reduce the effect of lens distortion, our cameras need to be calibrated through a calibration plate.
Checkerboard is the most common pattern of the calibration plate. We take pictures of the calibration plate and then correct the camera using the computer software model calculation results.
The calibration plate is very important. We can provide high-precision calibration plates and accept customized products from customers. Welcome to consult.
