when the projection function parameter in the projection parameters is left single-side projection or right single-side projection, the digital light processor at the vehicle end outputs a digital headlight corresponding to a projection control signal to the left digital headlight or the right digital headlight according to the projection angle parameter in the projection parameters and the real-time early warning information, and the real-time distance between the left rear and the right rear and the nearest moving object at the vehicle end is projected to the ground through the corresponding digital headlight;
when the projection function parameter in the projection parameters is double-sided projection, the digital light processor at the vehicle end generates two paths of projection control signals according to the projection angle parameter in the projection parameters and the real-time early warning information, the two paths of projection control signals are respectively output to a left digital headlight and a right digital headlight, the real-time distance between the left rear part and the nearest moving object at the vehicle end is projected to the left ground through the left digital headlight, and the real-time distance between the right rear part and the nearest moving object at the vehicle end is projected to the right ground through the right digital headlight.
9. The vehicle door opening early warning prompting method according to claim 1, wherein the pre-setting process of the projection parameters specifically comprises:
the cabin domain controller of the vehicle end receives a control instruction input by a user through an interactive system of the vehicle end, and the projection function parameters and the projection angle parameters of the digital headlamps at the left side and the right side in the control instruction are extracted and sent to the vehicle body domain controller of the vehicle end, so that the vehicle body domain controller sends the extracted projection function parameters and projection angle parameters as the projection parameters to the digital light processor configured at the vehicle end;
the digital light processor updates the real-time projection parameters according to the received projection parameters.
10. A vehicle door opening early warning prompt system, characterized in that the system is used for executing the vehicle door opening early warning prompt method according to any one of claims 1-9.
