Abstract: Provided are a fisheye camera calibration system, method and an electronic device. The system includes a hemispherical target, a fisheye camera and an electronic device. The hemispherical target includes a hemispherical inner surface and multiple markers provided on the hemispherical inner surface. The fisheye camera is used for photographing the hemispherical target and acquiring a target image, where the hemispherical target and the multiple markers provided on the hemispherical inner surface are captured in the target image. The electronic device is used for acquiring initial values of k1, k2, k3, k4, k5, u0, v0, mu and mv, and using a Levenberg-Marquardt algorithm to optimize the initial values of k1, k2, k3, k4, k5, u0, v0, mu and mv, so as to determine imaging model parameters of the fisheye camera.

Abstract: Provided are a fisheye camera calibration system, method and an electronic device. The system includes a polyhedral target, a fisheye camera and an electronic device. The polyhedral target includes an inner surface and multiple markers provided on the inner surface, and the inner surface is composed of multiple hexagonal and pentagonal planes. The fisheye camera is used for photographing the polyhedral target to collect a target image, where the polyhedral target and the multiple markers provided on the inner surface of the polyhedral target are captured in the target image. The electronic device is used for acquiring initial values of k1, k2, k3, k4, k5, u0, v0, mu, mv, Tj and Rj, and using a Levenberg-Marquardt algorithm to optimize the initial values of k1, k2, k3, k4, k5, u0, v0, mu, mv, Tj and Rj so as to determine imaging model parameters of the fisheye camera.
