A common phenomenon. The thermal chamber itself is not thermostamilized but is volatile, from there large calibration differences are obtained. It is very important at what angle the measurement is performed, because the ground layers of air fluctuate a lot within tens of centimeters for a few degrees, especially the morning evaporation 1-2 hours after sunrise. Above ice is also important turbulent ground flow and humidity just above the ground. also significant is the height of the measurement, the higher the temperature is measured by 1-2 degrees per 10 m for example. These anomalies are characteristic over meadows with grass, bushes, shade under trees. Do an experiment on a larger area, tilt the thermal imager below 10 degrees and keep the liver at a height of about 1-3 meters. You will see exactly the scales of temperature anomalies in a given area.
It is best to fix the drone at a certain height and turn the camera vertically down. you put a contact thermometer on the measuring point and report the difference as a correction value. Then you perform similar measurements at the places of interest. |
