Herein, a dual-lens laser profile measurement method was proposed to solve the problem of light stripe occlusion in the single-lens laser triangulation method. First, we experimentally observed and explored the distribution of light stripe in the sensor and its reasons for the formation. Moreover, we analyzed the surface morphology of the object, the relation between the optical system and light stripe distribution, and the light stripe distribution effect on three-dimensional reconstruction. Then, based on the direct incidence laser triangulation principle, a dual-lens measuring system was designed. Morphological processing combined with a gray-scale centroid method and other algorithms was used to extract the center coordinates of the light stripe. Finally, the dual-lens data were fused based on the minimization of variance. Experimental results show that the proposed dual-lens can solve the problem of large-area morphology loss caused by light stripe occlusion and reconstruct the complete envelope of the object's surface morphology. Furthermore, the associated data loss ratio was less than 0.5%.
