【摘要】 为解决现有技术中人工调焦工艺存在的生产效率低，且产品不良率高的技术问题，该文提出一种基于图像处理的软件自动调焦方案。该软件通过使用OpenCV提供的图像处理算法，实现图像的滤波降噪、特征提取和中心定位等功能，对比检测到的图像特征信息，自动调整激光雷达的发射镜头，使发射光斑达到最佳聚焦效果。同时，将光斑定位到预设位置，减小俯仰角误差，改善在安装镜头模组的过程中造成的倾斜问题。实验结果表明，软件具有较好的图像处理效果和较高的实用性，可以运用于科学研究及工业应用领域。更多还原

【Abstract】 To address the technical challenges of low production efficiency and high defect rates associated with manual focusing processes in existing technologies, this paper proposes a software-based autofocus solution utilizing image processing techniques. The software leverages image processing algorithms provided by OpenCV to perform functions such as image filtering,noise reduction, feature extraction, and center positioning. By analyzing the detected image feature information, it automatically adjusts the emission lens of the LiDAR system to achieve optimal focus of the emitted light spot. Additionally, it positions the light spot at a predefined location, thereby reducing pitch angle errors and mitigating tilt issues that occur during the installation of lens modules. Experimental results demonstrate that the software exhibits superior image processing capabilities and high practical utility, making it suitable for both scientific research and industrial applications.更多还原
