This function comprehensively considers the deviation degree between the actual pressure and the expected pressure and the cumulative pressure effect;

[0040] Step 2: Intelligent recognition and positioning

[0041] Use an intelligent recognition system to recognize and position the rearview mirror bracket to determine the press-fitting area on the bracket; among them, the efficiency of the intelligent recognition system is evaluated by the intelligent recognition and obstacle avoidance efficiency evaluation function E(θ, τ). The closer the value of E(θ, τ) is to 1, the higher the intelligent recognition and obstacle avoidance efficiency within time τ under the parameter set θ;
