Aspects described herein disclose picture projection techniques in virtual environments. The techniques may be performed by a vehicle simulator, the vehicle simulator may include an image generator and a projection device. The techniques may include performing scene rendering using the image generator based on scene data, to obtain a first scene picture, the scene data indicating a scene falling within a field of view when a first virtual scene is observed from a first virtual viewpoint, and the first scene picture being located in an image space; mapping the first scene picture to a to-be-projected picture using the image generator based on a first mapping relationship between the first virtual viewpoint and the image space, the to-be-projected picture being located in the image space; and performing projection display using the projection device based on a pixel value corresponding to each coordinate point in the to-be-projected picture, to obtain a projection picture. Picture projection accuracy is improved using the described techniques.
