【正文】 nds it to the SCM control system by the serial munication, realizes the control for camera according to each two meters to capture a frame. Because the system adopts the linear array camera, it needs to give a trigger signal in each millimeter to meet the accuracy requirement of detecting two millimeters width pavement cracks [7]. If the system does not adopt realtime control for the camera work frequency, most of the moving images received by linescan camera are not clear. Because the speed of the vehicle is always changing in the moving, using the control system designed in this paper will obtain much clearer road images [8]. Adopting fixed frequency acquisition method has no very good moving image effect. The system designed in this paper satisfies the pavement crack’s detection acquisition requirement. Meanwhile it lays a good foundation for the following image processing. Two examples of capturing pavement detection images are Fig 3 and Fig 4. Fig. 3. Realtime control capturing acquisition images Fig. 4. Non realtime capturing acquisition images 文獻翻譯 4 Conclusion The system design realizing the functions are as follows: (1) The system realizes the speed values measurement by designing hardware and software, programs to control GPS and SCM serial munication [9]. (2) According to the vehicle’s speed value, programs control SCM P20 port output voltage to supervise the work frequency of the linescan camera in realtime. (3) The system finishes the pavement crack’s detection accuracy requirement which is to recognize 2mm crack. It can obtain much clearer moving images and also run well in the highway detection. (4) By paring the acquisition image’s quality and large amounts of outside experiments’ data, it shows that the design system can obtain dynamic images clearly in high speed of vehicle moving. 文獻翻譯 References [1] Le, X., Zhiqiang, L., Feng, Z.: The study and realize of GPS supervision system.
