Design and Implementation of a 360° Panorama Imaging System Based on Motor-Driven Fisheye Camera
Abstract
This paper designs and implements a single-camera 360° panoramic imaging system based on motor-driven fisheye rotation. The system utilizes a stepper motor for precise angular control, enabling the camera to rotate around its optical center to capture multi-view images, thereby avoiding the parallax and geometric mismatch problems inherent in traditional multi-camera configurations. To address the strong distortion characteristics of fisheye images, an equidistant projection model is adopted for distortion correction. On this basis, a brightness normalization method combining global linear brightness correction and local illumination compensation is proposed to enhance stitching consistency. By establishing a geometry model constrained by camera rotation and integrating cylindrical projection with cosine-weighted blending, the system achieves high-precision panoramic stitching and seamless visual transitions.
