Method and apparatus for controlling projector

An apparatus for controlling a projector, the projector comprising a light source, a reflector, and an optical conversion device, the apparatus comprising:

• at least one processor;
• and
• a memory storing instructions, wherein the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• controlling the light source to emit point structured light to the reflector;
• and
• adjusting a tilt angle of the reflector to change the tilt angle of the reflector, to deflect, along a preset scanning direction, the point structured light reflected from the reflector to the optical conversion device including first to nth parallel line grooves, n being an integer greater than 1, the optical conversion device being configured for converting the point structured light incident onto the optical conversion device into line structured light, and the line structured light being used for forming a pattern that is projected onto a surface of a target object and extends along a direction intersecting with the preset scanning direction, wherein the adjusting a tilt angle of the reflector to change the tilt angle of the reflector comprises:
• controlling, by changing the tilt angle of the reflector to n different angles respectively, the point structured light reflected from the reflector to irradiate the first to nth line grooves one by one to form n line structured lights corresponding to the n angles;
• and
• projecting the n line structured lights corresponding to the n angles onto the surface of the target object to form the pattern with n line areas.

A projector, comprising:

• a controller including one or more processors;
• a light source;
• a reflector;
• an optical conversion device;
• and
• a memory storing one or more programs, wherein the one or more programs, when executed by the controller, cause the controller to perform operations, the operations comprising:
• controlling the light source to emit point structured light to the reflector;
• and
• adjusting a tilt angle of the reflector to change the tilt angle of the reflector, to deflect, along a preset scanning direction, the point structured light reflected from the reflector to the optical conversion device including first to nth parallel line grooves, n being an integer greater than 1, the optical conversion device being configured for converting the point structured light incident onto the optical conversion device into line structured light, and the line structured light being used for forming a pattern that is projected onto a surface of a target object and extends along a direction intersecting with the preset scanning direction, wherein the adjusting a tilt angle of the reflector to change the tilt angle of the reflector comprises:

• and
• projecting the n line structured lights corresponding to the n angles onto the surface of the target object to form the pattern with n line areas.
