Abstract
A control system (30) for a laser projector (10), a terminal (100) and a control method for the laser projector (10) are provided. The control system (30) includes a first driving circuit (31), a microprocessor (35) and an application processor (33). The first driving circuit (31) is connected with the laser projector (10). The first driving circuit (31) is configured to drive the laser projector (10) to project laser. The microprocessor (35) is connected with the first driving circuit (31). The application processor (33) is connected with the microprocessor (35). The application processor (33) is configured to send a control signal to the microprocessor (35) according to a distance between a human eye and the laser projector (10). The microprocessor (35) controls the first driving circuit (31) according to the control signal to enable the laser projector (10) to project laser according to a predetermined parameter.
