If you need to create an interior 3D model of a building traditionally, this would be a time-consuming project. But now, thanks to a new laser and camera-fitted backpack, you can create 3D models of buildings by just wearing the backpack in the areas you need to map. Check out the video after the jump to see it in action.
Revolutionizing 3D Modeling with Wearable Technology
The new technology has been developed by a Cal Berkeley team led by Professor Avideh Zakhor. This innovative approach is hoped to make video games more realistic and buildings more energy-efficient. The backpack is equipped with advanced lasers and cameras that scan everything from floor to ceiling without any human intervention, making the process not only faster but also more accurate.
The lasers and camera in the backpack scan everything from floor to ceiling without any human intervention. The inertial management unit localizes the backpack, lasers generate the geometry, and cameras generate the texture map. All three are fused for precise navigation. This fusion of technologies ensures that the data collected is highly accurate and can be used for various applications, from architectural design to virtual reality environments.
How It Works: The Technology Behind the Backpack
Once it’s turned on, there are four cameras taking pictures simultaneously. As one laser looks left, another looks right, one looks at the floor, and the last looks at the ceiling. This comprehensive scanning method ensures that no detail is missed, providing a complete and detailed 3D model of the interior space.
The inertial management unit (IMU) plays a crucial role in localizing the backpack within the space. It tracks the movement and orientation of the backpack, ensuring that the data collected by the lasers and cameras is accurately mapped to the correct locations. The lasers are responsible for generating the geometry of the space, capturing the shapes and dimensions of the walls, floors, and ceilings. Meanwhile, the cameras capture the texture map, providing detailed visual information that can be overlaid on the geometric model.
This combination of technologies allows for precise navigation and mapping, making it possible to create highly detailed and accurate 3D models quickly and efficiently. The potential applications of this technology are vast, ranging from improving the energy efficiency of buildings by providing detailed models for analysis to creating more realistic and immersive environments for video games and virtual reality experiences.
