Abstract
The present invention discloses a laser animation projection device. The device comprises a controlling mainboard, an X-axis high-speed galvanometer motor, a Y-axis high-speed galvanometer motor and a laser device; a MCU is disposed on the controlling mainboard; an X-axis galvanometer lens is connected to an output shaft of the X-axis high-speed galvanometer motor; a Y-axis galvanometer lens is connected to an output shaft of the Y-axis high-speed galvanometer motor; a display screen is disposed in front of the two galvanometer lenses; a WIFI module is disposed on the controlling mainboard; the laser device is positioned according to positions of the two galvanometer lenses, so as to make the laser emitted by the laser device be reflected onto the display screen through the two galvanometer lenses. A control method for the laser animation projection device is also disclosed.
