Method and device for projecting a starry sky image for a vehicle

Abstract

The invention provides a vehicle starry sky image projection method and device. The starry sky image projection method includes obtaining the current orientation and current time of the vehicle, the current orientation includes the current position of the vehicle and the current driving direction of the vehicle; acquiring astronomical position data of a plurality of stars corresponding to the current time and the current position of the vehicle; The astronomical position data of each star draws a starry sky image, and the starry sky image includes a plurality of single stars and each constellation formed by a plurality of stars; according to the current driving direction of the vehicle and the astronomical position data of each star, the orientation relationship of the starry sky image relative to the vehicle is determined; The azimuth relationship projects an image of the starry sky into the vehicle. Even if the orientation of the vehicle is constantly changing during driving, the position of the starry sky image can be adjusted according to the orientation relationship between the starry sky image and the vehicle, so that the projected position of the starry sky image on the vehicle changes with the change of the vehicle orientation, which improves the reality of the simulated starry sky. sex.

Description

Technical field [0001] The present invention relates to the technical field of the vehicle interior, in particular, it relates to an image projection method and apparatus Star a vehicle. Background technique [0002] Currently, many vehicles set up within the top stars. Existing sky top of each color light is transmitted to the top of the effect of different positions for simulating the sky starry sky through the optical fiber. However, the position of the optical fiber transmission in an analog starlight sky top is fixed, the position adjustment can not be made adaptive according to the change of the position and direction of the vehicle, starry sky not reflect the position of the vehicle relative to changes in the relationship, resulting in simulation results starlight lack of realism, reducing the user experience. Inventive content [0003] In view of the above problems, the present invention is to overcome the above problems or to provide an at least partially solve the sky ...

AI Technical Summary

Problems solved by technology

However, the position of the simulated starlight transmitted by optical fiber on the top of the starry sky is fixed, and it cannot make adaptive position adjustments according to changes in the position and direction of the vehicle, and cannot reflect the relationship between the position changes of the stars in the sky relative to the vehicle, resulting in a starlight simulation effect. Lack of realism, degrading user experience
