Software to restore cyclorama (360 deg. panorama) from photos
This application allows visually restore a cyclorama from a set of photos covering 360 degrees in all directions to horizon. It was specially designed to restore panoramas obtained by Apollo missions in 1969-1972 but it can be used to restore any cyclorama from photos got in your tourist trip (for example). The main principle of the program is in projecting photos on a 360x360 sphere and combining it together. If you select a correct field of view (FOV) for photo images, its combination...
It provides an USB connection for the communication with the PC, it uses a stepper motor that provides higher precision, you can set the motor in full step or in microstepp mode (1, 1/2, 1/4, 1/8). The focuser include a temperature sensor. This driver has a ToolBox with which you can control manually the focuser (for example you can set the limits).
