Abstract

Panoramic television images are used in a wide range of applications, including scientific and applied television, video surveillance systems, vision systems used in transport and robotics. The construction of panoramic images can be performed by assembling from several frames obtained using one rotary television camera or several stationary television cameras. However, such methods cannot be used for working with moving images, as well as in systems of mobile robots, where strict requirements are placed on the reliability and dimensions of the equipment. In these cases, the preferred method is the formation of a panoramic image using a TV camera with a high-resolution photosensitive sensor in combination with an ultra-wide angle lens such as fisheye. The article discusses one of the methods of forming a panoramic image in real time with field of view (FOV) corresponding to the hemisphere of 360 x 180 degrees.
