Whether you’re new to photography or a professional, digital cameras are packed with features to hone your techniques, enhance your shots and make photography a truly fun experience.
Calibration will mean you have a better, more accurate starting point and so each image will, in theory need fewer edits. Calibrating a camera works in a similar way: essentially you are measuring any variance in how it sees the world, and creating a profile to correct these individual differences at the raw processing stage.
Camera and lens calibration, or autofocus microadjustment (afma), is a procedure that allows a technician to adjust for front or back focusing autofocus errors. Even the highest-quality dslr photo equipment is not manufactured to identical specifications.

Geometric camera calibration, also referred to as camera resectioning, estimates the parameters of a lens and image sensor of an image or video camera.
Camera and laser are not aligned in the same relative direction. Current systems of calibrating a 2d lidar and an intrinsically calibrated optical camera do not achieve all three of these properties. Therefore, developing a user-friendly system to nd the calibration between these sensors is necessary.
