WebSep 13, 2024 · A fisheye lens is a camera component used for shooting extremely wide angles, typically 180 degrees. Also referred to as a “super wide” or “ultra-wide” lens, it produces an image that appears distorted, giving it a more abstract yet dynamic aesthetic. There are two main variations of this lens: full-frame and circular. WebFisheyeDet. The No-prior Fisheye Representation Method is proposed to guarantee that the network adaptively extracts distortion features without prior information such as prespecified lens parameters, special calibration patterns, etc. Furthermore, in order to tightly and robustly localize objects in fisheye images, the Distortion Shape ...
