The non-contact, high accuracy, fast speed and wide application are advantages of the structured light measurement technology. It is one of the most important directions in the field of 3D measurement. The paper compares three different forms of structured light. Three-dimensional measurement of the object is carried out based on the principle of triangulation. The single point cloud of the measured object is obtained by data acquisition. The rough and fine stitching of single point cloud data is accomplished by automatic stitching of marker points and stitching technology based on ICP principle. By aligning the stitched point cloud data with the theoretical model and creating the color map, we can get the error color map of the measured object. The actual state of the measured object is intuitively reflected. By using different equipment to measure the same part, the correctness of the results and the efficiency of measurement are verified. The measurement factor analysis can effectively improve measurement efficiency and reduce the influence of noise on measurement results.
