摘　　要：针对航空发动机叶片等复杂型面物体轮廓检测问题,提出多线结构光及多图像传感器测量技术方案。采用透镜针孔模型和畸变模型及多元函数的反函数组定律,建立了系统测量精度、测量范围与系统参数之间的关系,绘制了系统设计过程中的参考图表。这些参考图表也可以作为系统设计过程系统参数选择及检测过程中进行系统参数设置的依据。测量系统实例化及对叶片测量数据验证了所建系统模型的有效性。To perform the contour detection of aero engine blades and other objects with complex surfaces, a multi-resolution measuring system, which is composed of muhiple line structured light subsystems and cameras, is designed. The lens pinhole model, distortion model and the law of inverse function group are used to estab- lish a relationship between the measurement accuracy and range with system parameters. Some reference charts are drawn according to the relationship. These reference charts can be adopted as a foundation to set system pa- rameters in system design or testing process. Measured data of a blade from the designed system shows the es- tablished system model is effective.
