Development Case of a Glasses-Free 3D Vehicle Rear View System

Overview

• Customer: Renault (France)
• Industry: Automotive / Vehicle Display / Driver Assistance System
• Solution: Rear camera-based vehicle 3D rear view system
• Key Result:
  - Implementation of a rear view system that displays rear camera images in glasses-free 3D in real time
  - Improved driver distance perception accuracy
  - Verification of the applicability of automotive 3D display technology

1. Background and Challenge

Existing vehicle rear and side mirror systems are based on flat images, which can make it difficult for drivers to accurately understand distance and spatial relationships. This is especially important in situations such as parking or reversing. Because of this, interest in 3D-based vehicle vision systems has been increasing in the automotive industry.

2. MOPIC’s Solution

Renault installed a 3D camera in the vehicle rear camera system and developed a rear view mirror system prototype using MOPIC’s glasses-free 3D display module and 3D image processing technology. A system was implemented to display video from the rear camera in real-time 3D.

3D Rear View Display Optimized for Vehicle Environment

MOPIC developed a 9.2-inch glasses-free 3D display optimized for vehicle environments.

• 3D optical design considering driver seating position
• Eye-tracking based 3D display aligned with the driver’s viewing position
• Real-time 3D video display connected with a 3D rear camera

System Integration with Native 3D SDK

Using MOPIC’s Native 3D SDK, 3D functionality could be added to the existing rear camera system without major structural changes. The system also converts rear camera video into real-time 3D with ultra-low latency.

3. Results and Value

Improved Rear Visibility Recognition

With 3D rear view visualization, drivers can more intuitively understand distance and space behind the vehicle.

Expandable to Various Vehicle Camera Systems

The technology was designed to be applicable not only to rear cameras but also to side-view and front camera systems.

Enhanced Premium Vehicle Technology Competitiveness

By verifying the manufacturability and technical feasibility of automotive 3D displays, a foundation was created for next-generation vehicle interface development.

Customer Interview

One of the most important elements in vehicle safety systems is how accurately the driver can understand the surrounding environment. Through MOPIC’s glasses-free 3D display technology, we confirmed a new visual experience that helps drivers intuitively understand distance and space
