Abstract: Provided in the present disclosure are a video generation method and apparatus, and a device and a storage medium. The method includes: firstly, when an application request for a target effect object has been received, acquiring location information of the current user; then, on the basis of the location information of the current user, determining a target place of interest (POI) corresponding to the current user; acquiring an effect resource of the target POI, and on the basis of the location information of the current user and location information of the target POI, determining a direction relationship between the current user and the target POI; on the basis of the direction relationship, displaying, on a photographic page, a photographic effect corresponding to the effect resource; and then on the basis of the photographic effect corresponding to the effect resource, generating a result video corresponding to the target effect object.

Abstract: A machine tool rapid compensation system includes: a trigger acquisition module, a laser interferometry measurement module, a data analysis and compensation module, and a communication module. The trigger acquisition module receives a trigger acquisition instruction, converts an encoder position value into a pulse value, transmits the pulse value to the laser interferometry measurement module, retrieves parameter information and compensation point information of a machine tool from a numerical control system, and generates a machine tool operation code and a measurement preparation signal. The laser interferometry measurement module receives the measurement preparation signal and the pulse value to obtain error data, environmental data, and expansion compensation values.
