为有效提高抛物槽式太阳能聚光器的聚光效率，需要对聚光器各个反射镜的安装位置进行检测和校准。本文采用Marposs公司研发的VISField系统，利用吸热管反射成像法，根据相机与聚光器的相对位置关系，推导吸热管在子镜中的成像位置，进而完成聚光器各子镜位置误差的调整。以全站仪为第三方工具，利用外部靶点信息对吸热管进行位置调整以及完成相机姿态的动态校准。利用本文提出的方法进行实验，调整后各反射镜的平均截断因子近似为1，说明吸热管在子镜中的实际成像位置与理论成像位置近似重合，验证了检测方法的正确性和可行性。

To effectively raise the concentration efficiency of the parabolic trough solar concentrator, the detection and calibration of the installation position for each concentrator mirror are needed. The VISField system developed by Marposs Company is adopted in this paper. According to the relative position between cameras and concentrator, the image position of the endothermic tube in the sub mirror is derived with the refiection imaging method, and then the adjustment of sub mirrors’ position error is completed. With total station instrument as the auxiliary tool, the position adjustments of the heat absorbing tube and the dynamic calibration of the camera pose are completed with the external target information. The experiment is conducted with the method proposed in this paper. With the intercept factor of each mirror closing to 1 after adjustment, this experiment indicates that the actual imaging location and theory position of the endothermic tube in sub mirrors are approximately coincided, which verifies the correctness and feasibility of the method.
