V2X Sentinel Monitoring With Cooperative Vehicle Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles equipped with sentinel modes struggle to capture clear videos of suspicious targets on the side or rear due to inadequate lighting, leading to potential asset loss.
Innovation Solution
A vehicle-to-everything (V2X) server system that coordinates surround-view cameras and exterior lamps across multiple vehicles to illuminate suspicious targets, ensuring clear video capture by determining the position of targets and prompting adjacent vehicles to turn on their lamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle uses its own preset exterior lamp to illuminate suspicious targets, then the front suspicious targets are clear in the video, but the side and rear suspicious targets remain unclear due to insufficient lighting
Solution Approach 1:
The system combines lighting resources from multiple vehicles by having the V2X server coordinate exterior lamps from different vehicles to illuminate suspicious targets. When one vehicle's lamp is insufficient, adjacent vehicles are prompted to activate their lamps, merging the lighting coverage areas to achieve comprehensive illumination of the monitoring region.
Solution Approach 2:
The V2X server acts as an intermediary that receives image data from surround-view cameras, analyzes suspicious targets, determines lighting deficiencies, and coordinates lamp activation across multiple vehicles. This mediator enables indirect cooperation between vehicles without requiring direct peer-to-peer communication.
2Measurement precision
If the vehicle relies solely on its own lighting system, then the device complexity is low, but the video quality of suspicious targets in dark areas deteriorates
Solution Approach 1:
The V2X server serves as a centralized intermediary that handles the complex coordination logic. It receives images from multiple vehicles, identifies suspicious targets, determines which adjacent vehicles should activate lamps, and manages the cooperative lighting system. This centralizes complexity in the server rather than requiring complex distributed coordination in each vehicle.
Solution Approach 2:
The V2X server performs multiple functions: it acts as a communication hub for vehicle-to-everything data exchange, an image processing center for analyzing suspicious targets, a coordination controller for lamp activation, and a video quality monitor. This multi-functionality consolidates system complexity into a single platform.
3Illumination intensity
If adjacent vehicles activate their exterior lamps based on V2X server coordination, then the lighting coverage is improved, but the energy consumption of the multi-vehicle system increases
Solution Approach 1:
Instead of having all vehicles continuously activate their exterior lamps, the system uses partial action by selectively activating lamps only in adjacent vehicles that are needed to illuminate specific suspicious targets. The V2X server determines precisely which vehicles should activate lamps based on target position and lighting requirements, avoiding unnecessary energy consumption from excessive lamp activation.

AI summary
A method of monitoring is provided. The method obtains first images captured by surround-view cameras of preset vehicles in a monitoring area. Where each preset vehicle starts a sentinel mode, and each preset vehicle includes a surround-view camera. The method determines a second preset vehicle according to a second image if a suspicious target of a first preset vehicle appear in the second image, which is captured by the corresponding surround-view camera of the first preset vehicle and are from the first images, and a definition of the suspicious target in the second image is less than a preset value. Where the suspicious target appears in an illuminating area illuminated by a preset exterior lamp of the second preset vehicle. The method further prompts the second preset vehicle to turn on the preset exterior lamp. A related V2X server and a related storage medium are provided.
