AI Technical Summary

Technical Problem

In the current technology for hot-swapping and restoring vehicle cameras, the timed monitoring method consumes high processor resources, while the interrupt method consumes a lot of hardware resources, affecting the efficiency of the processor and hardware resources.

Method used

By determining the status of the interrupt pin used to trigger interrupts in the deserializer, data output can be restored when the camera is disconnected or its connection status changes. The port status of multiple cameras can be obtained using only one interrupt pin, reducing the consumption of processor and hardware resources.

Benefits of technology

During the camera hot-swap recovery process, processor resources are saved, the execution efficiency of other processor threads is improved, and hardware resource consumption is reduced.

Abstract

Disclosed are a multi-camera control method, apparatus, and device, and a storage medium, relating to the field of intelligent driving. The method comprises: determining an interrupt pin state used to trigger an interrupt in a deserializer; in response to the interrupt pin state indicating that at least one camera among a plurality of cameras is in a disconnected state, determining port states corresponding to the cameras at a first moment; and in response to the port state corresponding to a first camera among the plurality of cameras at the first moment switching from a disconnected state to a connected state, restoring data output of the first camera. According to the technical solution of the present disclosure, the connection status of each camera is determined only when a hot-plug action occurs, and corresponding data output is restored when the camera switches from a disconnected state to a connected state, thereby saving processor resources. In addition, the port states corresponding to the plurality of cameras can be determined simply by means of one interrupt pin in the deserializer, thereby significantly reducing the consumption of hardware resources.
