Design a method to measure instantaneous vehicle speed based on linear array CCD image sensor. The system uses linear array CCD as front-end detection equipment

C8051F010 as signal processing chip

correlation algorithm as core algorithm

it has advantages of high real-time performance

fast computing speed

and low requirements for environment measuring

which can satisfy the truck dynamic weighing algorithm for requirements of real-time and accuracy for instantaneous velocity. Provides a reliable velocity compensation method to effectively solve weighing accuracy of dynamic axle truck scale.
