A backlight detection method and device, and the method includes acquiring a brightness value of each image block in a to-be-checked image, determining a brightness relationship between the adjacent image blocks according to the brightness value of each image block; and determining a dark region and a bright region in the to-be-checked image according to the brightness relationship between the adjacent image blocks, and determining whether the to-be-checked image is a backlight scenario according to the dark region and the bright region. The backlight detection method and device provided by the embodiments of the present invention can improve accuracy of backlight detection.

Backlight detection method and device

A uniform turnover apparatus comprises a turnover body, a linear advance device, and a fixed base. The linear advance device has a fixed end and a movable end. The fixed end is turnably provided on the fixed base by a first fulcrum. The turnover body is movably connected with the movable end of the linear advance device by a second fulcrum. The turnover body is turnably provided on the fixed base by a third fulcrum. The first, the second, and the third fulcra form a triangle. The uniform turnover apparatus comprises a control device connected with the linear advance device. The control device acquires an actual angular velocity at which the turnover body is turned, and compares the actual angular velocity with a set angular velocity, and according to the comparison, adjusts the linear velocity of the linear advance device in real time, so that the actual angular velocity of the turnover body approximates or equals to the set angular velocity. The apparatus can make the turnover body turn placidly and effectively reduce the impact force during turning over.
