Display system and display method for augmented reality

A display system for augmented reality comprising:

• a display device configured for displaying a light-emitting mark, controlling flashing of the light-emitting mark to generate a flashing signal;
• and
• an augmented reality wearable device comprising:
• a wearable body;
• a light sensor on the wearable body, the light sensor detecting the light-emitting mark and the flashing signal;
• an image capturing device on the wearable body;
• a projection device on the wearable body, and configured for generating a projection image of an object;
• a database storing a reference flashing signal and a reference light-emitting mark image;
• and
• a processor coupled to the light sensor, the image capturing device, the projection device, and the database, wherein:
• when the processor receives the flashing signal transmitted by the light sensor, the processor retrieves the reference flashing signal from the database, and if the processor determines the flashing signal matches the reference flashing signal, the processor further retrieves the reference light-emitting mark image from the database, and if the processor determines the light-emitting mark matches the reference light-emitting mark image, the processor further controls the image capturing device to capture a light-emitting mark image, calculates a distance information and an angle information between the image capturing device and the light-emitting mark based on the light-emitting mark image, generates a projection parameters based on the distance information and the angle information, and controls the projection device to adjust the projection image of the object according to the projection parameters.
