The imaging quality of light stripe is one of the important factors determining the 3D measurement accuracy of line structured light. In order to solve the problems of poor consideration of the image's whole and details and lack of comprehensive evaluation criteria in the present imaging quality evaluation methods of light stripe, an imaging quality comprehensive evaluation method by multi-parameters of line structured light stripe is proposed. First, the characteristics of light stripe image set acquired with a gradual change in exposure time are analyzed from three aspects: one-dimensional image entropy, local contrast, and light stripe's definition. Then the imaging quality of light stripe images are reversely evaluated by the extraction accuracy of the image set's light stripe centers, and the change rule of multi-feature parameters with the light stripe center extraction accuracy is analyzed. Finally, the imaging quality is comprehensively evaluated by multi-feature parameters of line structured light stripe image set, and the multi-parameter comprehensive quantitative evaluation model is constructed. The experimental results show those the evaluation result of the proposed method is more accurate and effective than those of the existing methods, and the high-precision rack measurement results obtained from the evaluated high-quality light stripe images have the highest accuracy, whose R_ssa value is only 0.022.
