Analysis and compensation of error introduced by grid calibration for RFID package equipments

Abstract

Grid calibration of the visual system introduces the rotating linear deformation. Just to compensate actual error with the error obtained from the visual system would result in lower accuracy for equipments. This paper would establish the mathematical transformation model between image coordinate system and world coordinate system. Test results reveal that this optimal compensation effectively improve the compensating accuracy on the whole working plane.

Study on the Dynamic Weighing Measurement Accuracy of the No Parking Weight Charging System

“…These results show that the frequency of vibration of the vehicle is substantially consistent with the characteristic frequency of road, therefore, when considering the elimination of errors, mainly consider how to reduce the vibrations caused by road. The characteristics of the built pavement were determined by the construction index, and will change along with the changes of the surrounding environment, aged and worn over time, so the noise can only be eliminated by changing the layout mode of sensors [4,5,6,7] .…”
