Method, device and system for determining display limit of stereo display screen

The invention relates to the technical field of image processing and provides a method, device and system for determining the display limit of a stereo display screen. The method comprises the following steps: establishing one or more kinds of virtual scenes to be tested; receiving E_V and Z_V parameter values of the specific virtual scene to be tested, and providing a virtual stereo scene, constructed according to the E_V and Z_V parameter values, of the specific virtual scene to be tested; obtaining E_V and Z_V result data fed back when a test user watches the virtual stereo scene; obtaining F_R and N_R test values according to the E_V and Z_V result data; and obtaining reference limit values of the N_R and F_R. According to the provided method and device, the test result is obtained according to the parameter values fed back by the test user and by utilizing proportional mapping relation between the virtual scenes and real scenes; and the test result of the test user is obtained, and thus reference limits of the biggest display convex distance and concave distance of a real screen in the real scene are obtained.
