The size character, which represents the relationship of the size variables of a binocular vision model, is studied to determine the optimal structure of the measurement system. An optimal objective function is constructed to minimize the system area. The optimal solution with the constraint of the virtual baseline distance is obtained from the particle swarm optimization (PSO) algorithm. A case study shows that when the virtual baseline is 1300 mm, the optimal parameters are: the real baseline distance is 600 mm, the bottom distance between the two smaller mirrors is 120 mm, the distance from a smaller mirror to the camera is 600 mm, the distance from a larger mirror to the camera is 700 mm, the angle between the smaller mirror and baseline is 15 degrees, the angle between the large mirror and baseline is 30 degrees, larger mirror is 500 mm long, then the optimal system area is 0.838 m(2).
