Abstract: A light-deflection three-dimensional imaging device, a projection device, and the application thereof are disclosed. The light-deflection three-dimensional imaging device includes a projection device, a receiving device and a processor. The projection device includes a light source, a grating, a condensing lens group, a light deflection element and an emission lens, wherein after the modulation by the grating, the aggregation by the condensing lens group and the deflection by the light deflection element, the projection light transmitted by the light source penetrates the emission lens and is emitted from a side surface of the projection device.

Abstract: The present disclosure provides a method and system for data persistence in stream computing, and the present disclosure belongs to the technical field of data storage. The method comprises: initiating, by a management module, a task; extracting a key corresponding to the task from a data source based on the task; acquiring a value corresponding to the key from the data source based on the key, performing data processing to generate intermediate data and a first signal, and storing the intermediate data and the first signal; detecting whether the first signal has been stored, and sending detection information to the management module. By using the present disclosure, the intermediate data persistence result may be effectively fed back, such that the intermediate data persistence may be ensured to be transactional.
