Environment mapping is an important technology in the field of spatial computing, widely used in augmented reality (AR), virtual reality (VR), robotics and autonomous vehicle navigation. It involves creating a digital model of the physical environment that can be used by computers to understand and interact with the real world.
How does environmental mapping work?
- Collecting data: The process starts with collecting data about the environment, usually using sensors such as cameras, LiDAR (Light Detection and Ranging), infrared sensors and ultrasound. These devices collect detailed information about the environment, including distances, object sizes and spatial relationships.
- 3D modelling: The collected data is used to create a three-dimensional model (or digital twin) of the environment. This model includes all physical objects and their positions in relation to each other.
- Real-time updates: For systems operating in dynamic environments, such as robots or AR applications, the map of the environment is updated in real time to reflect changes such as moving objects or changing lighting conditions.
Environmental mapping applications
- Augmented Reality: In augmented reality, environment mapping enables realistic placement of digital objects in the physical world and enhances user interaction by allowing virtual objects to hide behind or interact with real objects.
- Virtual Reality: In virtual reality (VR), environment mapping can be used to create immersive and interactive virtual environments modelled on real-world locations.
- Robotics: Robots use environment mapping for navigation and obstacle avoidance, allowing them to move autonomously through complex environments.
- Autonomous vehicles: Self-driving cars use environment mapping to safely navigate roads and detect and avoid obstacles such as other vehicles, pedestrians and roadblocks.
Environment mapping is essential for developing systems that can seamlessly merge digital content with the real world, and is a fundamental technology for many innovative applications in technology and industry.
