摘　　要：采用地面三维激光扫描技术进行精密工程测量,具有速度快、非接触性、实时动态及高效率、高精度、自动化等特性。本文以广州正佳海洋世界主缸亚克力板申报吉尼斯纪录关键指标精密工程测量为例,通过与全站仪的精度比较试验,利用三维建模算法得到的测量成果与全站仪的测量结果宽度和弧长较差分别在7mm和12mm,表明地面三维激光扫描技术在精密工程测量中的可靠性。The technology of ground 3D laser scanning is used for engineering surveying. It has the characteristics of fast speed, non-contact, real-time dynamic and high efficiency, high precision and automation. In this paper, high precision engineering survey of the key indicators of Guangzhou Zhengjia marine world master cylinder acrylic panel for the application of Guinness Book of Records is introduced as an example. Through comparison with the total station, the differnees of using three-dimensional modeling algorithm and the total station measurement results on the width and arc length is less than 7mm and 12mm, respectively. It verifies the reliability of ground 3D laser scanning technology in precision engineering survey.
