Calibrating a Camera
Calibrating a camera is necessary in order to estimate object parameters such as height,
area, speed and classification. If you know the height, tilt angle and vertical field of view
corresponding to your installation, you can simply type the parameters in the appropriate
boxes and apply the changes.
If however, you do not know, or are unable to find out the camera parameters, this topic
provides a step-by-step guide to calibrating a camera.
Step 1: Find some people in the scene
Find some people, or some people-sized objects in the scene. Try to find a person near the
camera, and a person further away from the camera. Place the mimics on top of or near the
people. Enter in the known height or estimated height.
