Abstract: Currently A-pillar ergonomics evaluation lacks of enabling tool for helping style designer actively participate in automotive design process,therefore,based on augmented reality,a new method for A-pillar evaluation is proposed.Firstly,an assessment environment including hardware and software systems is established,which superimposes the virtual vehicle model to the physical driving mockup precisely in real time.Secondly,virtual visual cone models for left and right eyes are constructed.A calibration method is designed to map the real eye points with the virtual ones in the visual cones,and an algorithm for A-pillar's blind angle calculation is proposed based on vision line collision detection.The method is proved to be reliable through detailed analysis of calibration error's influence on the computational accuracy of blind angle.Lastly,the above system and method are verified by an application of a certain car model's A-pillar evaluation.The virtual visual cones are driven by tracking the user eyes' positions while he is sitting in the physical driving mockup.The blind zone angle of A-pillar can be calculated quickly for different driving postures,and the impact of A-pillar on the front view can be subjectively evaluated by the user.The results show that the method is simple and effective,and a new assessment tool is provided for the automotive A-pillar evaluation.
