由于复杂度较高的跟踪算法多数采用国外芯片实现，基于国产FPGA的跟踪方法得到了研究。针对易于FPGA设计的模板匹配算法鲁棒性不足的问题，基于绝对差和(SAD)相似性度量方法，提出了求窗口内最小绝对差和(SMAD)的方法。利用最大值和最小值滤波预先处理窗口内图像数据，再求最小绝对差，将SMAD算法的加减法器资源消耗降低为原来的31.8%。提出的类金字塔的方法在节省逻辑资源的同时，提高了对目标尺度变化的适应性。OTB数据集的实验表明：提出的方法与鲁棒性较高的DDIS算法相比，跟踪成功率和平均重叠率分别提高了1.18%、0.13%，又有易于流水线设计的优势。利用国产FPGA实现了帧率可达100 fps的实验系统并验证其跟踪性能，为在国产FPGA上实现高帧率目标跟踪系统提供了解决方案。

吸热管表面能流密度分布的均匀性对线性菲涅耳式聚光器的光热性能及安全运行有着重要影响。基于Tonatiuh光学仿真软件构建了线性菲涅耳式聚光器模型，研究了圆柱面形反射镜焦距及瞄准点位置与光斑宽度之间的关系，在此基础上探讨了不同瞄准策略下线性菲涅耳式聚光器的光学效率及能流分布的均匀性。结果表明：采用瞄准点均匀分布的瞄准策略，聚光器在保持较高光学效率的同时能够提升集热管表面能流分布的均匀性。采用优化后的瞄准策略，线性菲涅耳式聚光器光学效率可达到87.4%，集热管表面能流密度标准差由45.3%降低到30.7%，集热管顶部能流密度提升了10.2%。集热管空管预热采用该优化瞄准策略，在变占空比跟踪模式下，集热管弯曲变形程度远小于现有瞄准策略。该结果可为线性菲涅耳式聚光集热系统的优化设计提供理论支撑。

光学三维测量中的三通道相位测量轮廓术具有高精度、易识别、自动化程度高等优点，在科学研究和工程应用中获得了广泛的关注。在三通道相位测量轮廓术中，投影仪不同通道间的色差成为影响测量精度的关键因素。针对该问题，文中开展了基于相位标靶的相位测量轮廓术投影色差建模与校正研究。提出了将带有全息投影膜的液晶显示屏（Liquid Crystal Display, LCD）当作相位标靶对投影色差建模与校正的方法。通过LCD显示条纹与投影仪投射条纹的相位，计算投影仪色差并建立其数学模型。然后通过预补偿的方法实现投影仪三通道投射色差的校正，进行实验验证校正前后对相位测量轮廓术精度的影响。实验结果表明，文中所提方法的校正效果为蓝绿通道的平均色差由0.3255 pixel校正为0.1063 pixel，红绿通道的平均色差由0.3651 pixel校正为0.1114 pixel。该方法可为三通道相位测量轮廓术提升投影质量。实测台阶的平均误差从0.489 mm减少到0.038 mm。实验结果验证了投影仪色差建模与校正方法的有效性，提升了三通道相位测量轮廓术的整体测量精度。与已有方法相比，可以有效避免相机误差带来的影响，大大缩短计算时间，能够适用于不同型号的投影仪色差测量与校正。
