Method for transforming deserializer driver of vehicle-mounted camera system and related device

Abstract

The invention provides a method for transforming a deserializer drive program of a vehicle-mounted camera system and a related device, and the method comprises the steps: firstly removing a judgment condition of direct return failure and ending when detecting that a camera module is not connected in the deserializer drive program, and then adding a preset registration judgment logic in the deserializer drive program; when the vehicle-mounted camera system is started and a camera module is detected to be not connected, registering a serializer driver program and a camera driver program into a deserializer driver program by a preset registration judgment logic; when the vehicle-mounted camera system is started and a camera module is detected to be connected, registering a serial adding device driving program and a camera driving program into a deserializer driving program by a preset registration judgment logic, and driving a corresponding serial adding device and a camera according to the serial adding device driving program and the camera driving program; the problem that in the process of camera driving to register from equipment to deserializer driving in a related scheme, a camera module must be in a connection state when a system is started is solved.

Description

technical field [0001] The present invention relates to the technical field of communication electronics, in particular to a method for transforming a deserializer driver of a vehicle-mounted camera system and a related device. Background technique [0002] In order to meet the automotive-grade requirements, in-vehicle camera systems generally need to use a deserializer. like figure 1 As shown, the existing vehicle camera system includes a controller composed of a central processing unit and a deserializer, and a camera module composed of a serializer and a camera. Wherein, the central processing unit and the deserializer are connected in communication, and the central processing unit is used for receiving the data stream deserialized by the deserializer. The hardware interface of the deserializer is connected to the corresponding hardware interface of the serializer through a dedicated wire harness to receive the data serialized by the camera through the serializer.
