汽车中人体姿态三维测量对汽车座椅设计的舒适性评价具有重要的意义。为了快速准确地获取车内人体三维数据，文中采用一种基于双目视觉的立体三维数据获取方法，该方法将结构光与标记点相结合，实现了人体三维点云快速重建以及三维姿态(距离、角度)自动快速测量。实验结果表明，该方法在距离2 m以上，测量范围1.5 m×2 m时，人体姿态测量精度可以达到0.03 mm，满足了汽车人体姿态高精度三维数据采集的需求。与传统的汽车人体姿态三维测量方法相比，文中所使用的三维自动测量方法不仅自动化程度高，而且具有测量精度高、速度快、鲁棒性强的优点。

The three-dimensional measurement of human body posture is of great significance to the comfort evaluation of car seat design. In order to acquire the 3D data of the human body in the car quickly and accurately, a method of 3D data acquisition based on binocular vision was adopted, which combined the structured light with the marked points, and realized the rapid reconstruction of 3D point cloud of the human body and the automatic and rapid measurement of 3D attitude (distance and angle). The experimental results show that when the distance is more than 2 m and the measuring range is 1.5 m × 2 m, the measurement accuracy of human body posture can reach 0.03 mm, which meets the demand of high-precision three-dimensional data acquisition of automobile human body posture. Compared with traditional three-dimensional measurement method, the three-dimensional automatic measurement method used in this paper not only has a high degree of automation, but also has the advantages of high accuracy, fast speed and strong robustness.
