人造板厚度激光非接触测量研究
Non-contact Measurement of Wood-based Panel Thickness by Laser

厚度是人造板重要参数之一，随着人造板工业的高速发展，对人造板厚度的测量精度和检测方法也提出了更高的要求。采用上下2台激光传感器对人造板厚度进行了静态和动态非接触测量试验研究，提出了上下2激光传感器间距的标定方法，认为人造板厚度激光非接触测量是完全可行的。在被测板材静止状态下，激光检测厚度与板材厚度实际值之间误差非常小；在板材移动状态下，可以实时得到板材激光检测厚度值。
Thickness is one of the most important parameters of wood-based panels. With the rapid development of wood-based panel industry, higher requirements are needed for the measurement precision and detection methods. In this paper, two laser sensors (up and down the panel) were adopted to carry out dynamic and static non-contact thickness measurement. The calibration method for the distance of two lasers was proposed. It was proved that when the panel was static, minor errors of the measurement was observed with actual values of thickness, with the mobile state of the panel, real-time measurement could be achieved, indicating that non-contact measurement of wood-based panel thickness was completely feasible
