Abstract: A near space atmospheric state simulation method and device based on the quantum walk comprises: firstly, based on a characteristic of a near space atmosphere changing along with latitude, dividing a study region into a plurality of bands according to the latitude; secondly, based on a one-dimensional topology network constructed by the bands, simulating interaction and transfer processes of gas molecules between the bands by quantum walk to obtain all possible near space atmospheric evolution models; then, screening for actually existing evolution models in each of the bands based on stepwise regression by taking observed atmospheric density data as constraint conditions; and finally, constructing a mapping mechanism between a plurality of near space atmospheric evolution models and atmospheric density parameter values to achieve simulation and optimization of near space atmospheric states.

Abstract: This application relates to an image processing method and apparatus, a storage medium, and a computer device. The method can include obtaining image frames acquired from a real scene, and playing the obtained image frames one by one according to an acquisition time sequence. The method can further include determining a position corresponding to a target object in the real scene when a trajectory formed by a movement of the target object in a plurality of the obtained image frames meets a trigger condition, rendering a virtual entry in a currently played image frame according to the position, and displaying virtual content in the virtual entry. The solutions provided in this application improve image processing efficiency.

Abstract: Embodiments of this application provide an image display method performed at a terminal device. The method includes: capturing, by the terminal device, a first image; obtaining, by the terminal device, information about a first posture, the first posture being a posture of the terminal device when the terminal device captures the first image; determining, by the terminal device, a first movement track for a virtual object to move from a first position to a second position in a virtual world according to the information about the first posture; and presenting, by the terminal device, the first image as a background image of the virtual world, and dynamically rendering the virtual object to move along the first movement track in the first image, so that the virtual object moves vertically to the horizontal plane in the real world regardless of the first posture of the terminal device. Therefore, fidelity of the AR technology is improved, and user experience is improved.
