Different regulations define different directions for calculating this coefficient: in the direction of the main camera,
in the direction of the set of cameras, in four main directions. Or all of them (as in FIFA regulations).
Measurement of vertical illumination according to FIFA regulations on a football pitch with a team of 4 people using classical technology
with a conventional light meter takes about 6 hours and one day to process the results.
To alleviate the process, we have developed two versions of meters for vertical and horizontal illumination:
- with a set of fixed sensors;
- with movable sensors, sequentially measuring the vertical illumination at a point with a given step.
Inside the meter there is a processor that collects data from sensors installed on the surface of the device and after processing sends the received data into a special application on your smartphone.
