Abstract

Dynamic three-dimensional surface measurement based on line-scan cameras has been developing gradually. Line-scan cameras have the advantage of high resolution and a high line rate. In this article, a measurement system based on triple line-scan cameras is presented. The measurement model is established considering the asynchronous acquisition of the same point. The point cloud optimization algorithm helps to minimize the error caused by six-degree-of-freedom vibration. Theoretical analysis reveals that the resolution of the method is approximately 0.07 mm, and the measurement uncertainty is about 0.025 mm. Experiments demonstrated the feasibility of the method.
