Description

A method of fast visual field checking for automobile ergonomics

This application is a divisional application for an invention patent with the application number: 201710689169.6, application date: 2017-08-11, and the patent name "A method for checking the ergonomic vision of an automobile".

technical field

The invention relates to the field of automotive ergonomics testing, in particular to a method for fast visual field checking for automotive ergonomics.

Background technique

The visual field design in automotive ergonomics is a very important content, and it is the main factor affecting the active safety of the car; for this reason, the visual field requirements of the car driver are guaranteed, such as external signals and signs, road boundaries, passing vehicles The identification and information acquisition of pedestrians and road pedestrians are the tasks of car vision design.

For example, the size of the windshield of the car will affect the driver's forward vision, and the A-pillar will cause a certain blind spot in the driver's forward vision. For safe driving, these factors have corresponding standards and specifications; There are two kinds of design methods, one is the traditional drawing method. The mapping method calculates the field of view of the eye ellipsoid, but this method is cumbersome, and the accuracy of human work map verification is low, which is prone to errors;

Another design method is to put the drawn 3D model of the car into the ergonomics checking software, and the software will automatically generate the field of view. Static calibration is performed at a certain angle, but the position and rotation angle of the exterior rearview mirror and the interior rearview mirror used in practice are adjustable, which causes a certain degree of error, and the calibration result is inaccurate; The drawing is very complicated, and the overall model of the car is not actually needed for the field of vision check, but only the shape of the partial parts that block the field of view. The 3D model is simplified, which further increases the workload of checking;

The above two methods will have some deviations from the actual situation during calculation, and it is difficult for designers to find problems in the design or verification stage, and there is no way to effectively test the verification situation; , it is also necessary for the tester to sit in the car to carry out the corresponding test, such as whether the upper and lower boundary lines of the rear windshield meet the requirements in the front view, the tester needs to sit in the car, and then observe the car through the interior rearview mirror. The rear object is judged by the tester. The subsequent manual verification process is cumbersome, and in order to keep the result correct, the precision of each step is very high, which further increases the difficulty of manual verification; It is easily affected by the on-site environment, such as light brightness, calibration objects and other factors, resulting in unsatisfactory results of manual calibration.

The described manual checking step includes the following steps performed in sequence;

j. The tester sits on the test seat 62 after wearing the VR glasses 61 , and looks ahead at eye level. The camera 63 reads the position of the VR glasses 61 at this time, and the controller 5 calculates the position of the tester's human eyes according to the position of the VR glasses 61 . , when the tester's eye position is within the standard eye ellipsoid range, enter step k, otherwise prompt to re-adjust the sitting posture, and repeat step j;
