This article presents microprocessor measurement techniques for a multi‐cameera video system mounted in a van type vehicle that will observe a 12‐foot lane of road surface. Because of the high speed processing requirement of the vision system, several 68020 microprocessors are employed to handle data and detect various cracking patterns while the vehicle is in motion at highway speeds. As the image processing system collects the data, a host microprocessor computes an instantaneous and cumulative pavement score that will be used by the operator and the Pavement Management System, PMS, for further analysis and maintence considerations. The article presents an overview of the microprocessor driven PMS using high speed hardware circuitry for real‐time processing. Development of the system is underway by the Earth Technology Corporation and Louisiana Tech University.
