Background: Normal green channel vehicle inspection methods have many flaws
such as low efficiency and long time expense. The accuracy depends on the experience of inspector and it can not meet the online inspection. Purpose: The aim is to develop a new method which can help the inspector to promote the vehicle inspection speed and accuracy. Methods: Using real time image processing and control system
a new imaging system was developed. Results: The actual test shows that the inspection time can be reduced to less than one minute and the inspectors can also be reduced to one or two persons. Also the inspection accuracy is greatly improved. Conclusion: The imaging system achieves good effect through actual tests. Abstract
