Expanding Computer Vision Multi-View Stereo Capabilities: Automatic Generation of 3-dimensional Models via 360 Camera Footage | Taiwan AILabs
As the world we live in is three-dimension, 3D model is the most iconic representation of our world. 3D modeling allows people to see what they would not see when viewing in 2D. It gives people the ability to physically see how much real estate an object takes from all perspectives. But compared to generated from scratch, we are also able to build 3D models from video automatically. Taiwan AI Labs has built a virtual aerial website: droneye.tw. This website has great 360 video resources. It triggers an idea. Can we use 360 videos to generate high-quality 3D model within only few flights in order to minimize the cost to obtain the 3D model? Indeed, it is feasible no matter using stereo-views computer vision algorithm or deep learning approach. The concept of 3d model reconstruction can be illustrated as figure 1 that we are able to solve 3D object coordinate from the same point on the at least 2 images. Fig 1.
