便携式激光路面弯沉测定仪

Portable Laser Pavement Deflection Measuring Instrument

叙述了激光路面弯沉测定仪的原理、仪器结构以及技术关键。利用计算机数字图像技术对激光成像进行处理 ,提高了路面弯沉量的测量精度。实测表明 ,与传统方法相比 ,其精度由原来的 0 .0 1mm提高到 0 .0 0 7mm。

This article describes the development meaning of the laser pavement deflection measuring instrumentation,the measuring theory,the structure of the instrument and the critical technology. With the help of digital image technology to dispose the laser imaging,the measuring precision of pavement can be improved. The measured result indicates that,compared with traditional methods,the precision can be improved to 0.007mm from previous 0.01mm. It has great directive meaning to develop other modem pavement measuring instruments with laser method.
