Highway engineering quality is the lifeline of highway. Ground-penetrating radar is a new nondestructive testing technology of the road quality detection. This thesis takes advantage of ground-penetrating radar to analyze and discuss several related factors on highway nondestructive testing, for instance, the water content and compact degree of the base course, identification of cavity beneath the rigid pavement, and the differential settlement of the base course beneath the flexible pavement. Results of this research provide an excellent detection method for engineers and technicians.

In modern industry, the nondestructive testing of printed circuit board (PCB) can prevent effectively the system failure and is becoming more and more important. As a vital part of the PCB, the via connects the devices, the components and the wires and plays a very important role for the connection of the circuits. With the development of testing technology, the nondestructive testing of the via extends from two dimension to three dimension in recent years. This paper proposes a three dimensional detection algorithm using morphology method to test the via. The proposed algorithm takes full advantage of the three dimensional structure and shape information of the via. We have used the proposed method to detect via from PCB images with different size and quality, and found the detection performances to be very encouraging.
