Abstract: The embodiments of the present disclosure disclose a driving risk prediction method, apparatus, system, vehicle, and storage medium. The method includes: determining a dynamic object for a vehicle while driving; determining a first position of the dynamic object in the vehicle; determining, based on the first position and a structure of the vehicle, a first static object in the vehicle corresponding to the dynamic object; and predicting a driving risk corresponding to the dynamic object based on an interactive action between the dynamic object and the first static object.

Abstract: This disclosure provides a method for searching for an item, a computing device, an Internet of Things system, a device, and a storage medium. First item information and first sensor information corresponding to a first event are determined through an item query system. The first sensor information includes sensor information of a first sensor, which includes a sensor corresponding to at least one registered place. The registered place is a place registered in the item query system. After that, a first image acquired by the first sensor is obtained. Further, search for the first item is performed based on the first item information and the first image, to obtain a first search result. In this way, item search effects can be improved.
