Abstract
A control system (100) for a structured light projector (200) and an electronic device (1000) are provided. The control system (100) includes a first driving circuit (10) and an application processor (40). The first driving circuit (10) is connected with the structured light projector (200), and is configured to drive the structured light projector (200) to project laser. The application processor (40) is configured to control the first driving circuit (10) to be switched on and switched off based on a detection signal.
Claims20
A control system for a structured light projector, comprising:
- a first driving circuit, connected with the structured light projector and configured to drive the structured light projector to project laser;
- a microprocessor, connected with the first driving circuit and configured to provide a driving signal for the first driving circuit;
- and
- an application processor, connected with the microprocessor and the first driving circuit, and configured to:
- receive a control instruction of turning on or turning off the structured light projector;
- provide an enabling signal for the first driving circuit;
- transmit an instruction of controlling the microprocessor to provide the driving signal for the first driving circuit in response to that the control instruction of turning on the structured light projector is received, or transmit an instruction of controlling the microprocessor to stop providing the driving signal for the first driving circuit in response to that the control instruction of turning off the structured light projector is received;
- receive a detection signal, wherein the detection signal is an output current of the first driving circuit or is an image sent by the microprocessor;
- restart the microprocessor or not based on the detection signal;
- and
- control the structured light projector to be turned on or turned off.
