基于双2D激光位移传感器的空间运动物体位置探测

摘要

To gain the position of spatial motion objects, it is needed to detect the three-dimensional coordinate of measured object feature points constantly. So there is a spatial motion objects detected system based on double 2D laser displacement sensor. First of all, there is an introduction about double 2D laser displacement sensor, including double 2D laser displacement sensor's principle and sensor type. Secondly, introducing the project based on double 2D laser displacement sensor and axial and vertical coordinates detection simulate experiments to prove the project is available. Experiments prove that the spatial motion objects detected system based on double 2D laser displacement sensor is not influenced by measured object's cambered surface. It has high detection precision and doesn't deal with flexible informations. The sample frequency is 10k highly. All these are better to raise signal detection's instantaneity.%要获得空间运动物体的位置，需要实时探测被测物体特征点在空间中的三维坐标信息，为了解决这一问题，提出了基于双2D激光位移传感器的空间运动物体探测系统。首先，对2D激光位移传感器进行了简单的介绍，包括2D激光位移传感器的工作原理及传感器的选型；其次，详细介绍了双2D激光位移传感器三维定位方案，包括方案的选择及方案的实现原理；最后，通过被测物体横、纵坐标探测模拟实验，以及轴、纵坐标探测模拟实验两个实验，验证了方案的可行性。实验证明基于双2D激光位移传感器的空间运动物体位置信息探测系统不会受被测物体的圆弧面的影响，且探测精度高、无需通过复杂的信息处理，采样频率最高可达10K，有利于提高信号探测的实时性。
