WebCubemapSLAM is a real-time SLAM system for monocular fisheye cameras. The system incorporates the cubemap model into the state-of-the-art feature based SLAM system ORB-SLAM to utilize the large FoV of the fisheye camera without introducing the distortion. The system is able to compute the camera trajectory and recover a sparse structure of the ... Web5 de out. de 2024 · There are two major types of distortion effects : Radial distortion: This type of distortion usually occur due unequal bending of light. The rays bend more near the edges of the lens than the rays near the centre of the lens. Due to radial distortion straight lines in real world appear to be curved in the image.
