Problems solved by technology

However, while thinking of technical means to increase the FOV field of view, because the car is a mobile carrier, it is inevitable that the equipment and personnel in the car will shake together due to the bumpy road during the whole moving process. How to effectively evaluate the rise of AR HUD augmented reality Whether the augmented reality image emitted by the display device can bring a good experience to the driver during the whole bumpy process is a new topic

Embodiment Construction

[0027] The present invention is an integrated test-bed based on AR-HUD augmented reality on-vehicle target tracking effect, such as figure 1 As shown in Fig. 1, the integrated test bench includes front shield, instrument panel, driver's seat, augmented reality head-up display device AR HUD, projector, camera and vibration table, simulating the positional relationship between the driver and the road surface and AR HUD.

[0028] A kind of test method based on AR-HUD augmented reality of the present invention to target tracking effect in vehicle is first required to carry out the following preparatory actions during actual testing:

[0029] 1. To use the vibration table to simulate the vehicle road surface, it is necessary to collect the vibration curves of multiple test vehicles during the engine start-up process in advance, and take the maximum value of parameters such as acceleration, frequency, and amplitude as the upper limit of the parameters of the random vibration table; ...

Abstract

The invention discloses an AR-HUD-based test method for vehicle-mounted target tracking effect. Random jitter caused by real vehicle on road is simulated through a vibration table, and test verification is carried out on the problems of adaptation between augmented reality head-up display equipment ARHUD and a driver view image in a real vehicle on road pitching motion state. According to the invention, joint debugging can be carried out in an indoor darkroom, direct setout under the condition of basic function deficiency is avoided, the debugging efficiency is greatly improved, and the subjective test time cost is estimated to be reduced by more than 80% compared with that of the on-board debugging. In the AR-HUD development process, the problems of bumping, driver eye box deviation and the like in the moving process of a real vehicle are solved, separation from the real vehicle is achieved, the decoupling performance is high in the development and debugging process, and the method does not depend on objective conditions such as vehicle types and road environments.

Description

technical field [0001] The present invention relates to a kind of test method based on AR-HUD augmented reality on vehicle target tracking effect, belongs to the field of intelligent cockpit display. Background technique [0002] AR-HUD (Augmented Reality HUD) is called an augmented reality head-up display device, such as figure 2 As shown, mainly through AR technology, the current speed, navigation and other information are projected onto the photoelectric display device on the windshield, so that the driver can observe the actual road conditions more intuitively. Drivers can see navigation and vehicle speed information without turning or lowering their heads, which is the future of intelligent driving. [0003] AR HUD augmented reality head-up display device is a relatively advanced vehicle-mounted projection technology in the past two years, and it is a new challenge for every worker in the automotive industry. For AR HUD augmented reality head-up display devices, how t...
