Control method based on image processing

The invention relates to a control method based on image processing. The method comprises the steps that a gate self-control platform based on image processing is provided and operated and comprises a gate switch, voice warning equipment, light-emitting equipment, a gate mechanism, collision detecting equipment and main control equipment; and the main control equipment is connected with the gate switch, the voice warning equipment, the light-emitting equipment and the collision detecting equipment, the gate switch is connected with the gate mechanism and used for controlling starting or stopping of the gate mechanism, and the collision detecting equipment is arranged on the gate mechanism and used for detecting whether collision behavior exists on the gate mechanism or not. When the collision behavior exists, collision generation signals are sent out, and otherwise, collision-free signals are sent out; and when the main control equipment receives the collision generation signals, warning driving signals are s
