We present a novel calibration method for a multi-view laser Doppler speed sensing (MLDSS) system. In contrast with the traditional method where only the laser geometry is independently calibrated, the proposed method simultaneously optimizes all the laser parameters and directly associates the parameters with a motion sensing model. By jointly considering the consistency among laser Doppler velocimetry, the laser geometry and a visual marker tracking system, the proposed calibration method further boosts the accuracy of MLDSS. We analyzed the factors influencing the precision, and quantitatively evaluated the efficiency of the proposed method on several data sets.
我们提出了一种新的多视角激光多普勒速度传感（MLDSS）系统校准方法。与传统方法仅独立校准激光几何结构不同，该方法同时优化所有激光参数，并直接将参数与运动感应模型相关联。通过综合考虑激光多普勒测速、激光几何结构和视觉标记跟踪系统之间的一致性，该校准方法进一步提高了 MLDSS 的精度。我们分析了影响精度的因素，并在多个数据集上对提出的方法的效率进行了定量评估。
