What does "Voxel Maps" mean?
Table of Contents
Voxel maps are a way to represent three-dimensional spaces using small cubes called "voxels." Each voxel can hold information about what is in that part of the space, like the type of ground or obstacles.
How They Work
In a voxel map, the area is divided into a grid of these cubes. Each cube can tell you whether it is empty, has vegetation, or contains something else. This helps in understanding how a vehicle can move through different environments, especially where the ground is uneven or there are many plants.
Why They Are Useful
Voxel maps are helpful for vehicles that drive on rough terrain, such as off-road vehicles. They can quickly assess if a route is safe to take. By using a combination of data from images and sensors, these maps help the vehicle decide where it can and cannot go.
Examples of Use
In challenging outdoor areas, voxel maps can identify hazards, like hidden rocks or dense bushes, making it safer for autonomous vehicles to navigate. They can also adapt to different conditions over time by updating the information they hold about the environment.
Conclusion
Overall, voxel maps provide a clear picture of the space around a vehicle, allowing it to move confidently in areas that are difficult to manage. They are an important tool for improving safety and efficiency in off-road navigation.
