Method and apparatus for correcting projected image, projection device, capturing device, and medium

A projection device, comprising a processor and a memory, wherein the memory is coupled to the processor and stores instructions, and the processor is configured to execute the instructions to:

• form a test image through projection onto a target reflecting surface, to acquire a template image wherein the template image is an image generated by capturing the test image when edges of the test image are located within a preset capturing region, the capturing region is a region formed between a preset first capturing frame and a preset second capturing frame, and the second capturing frame surrounds a periphery of the first capturing frame;
• frame surround ring frame:
• acquire, based on a deviation between the template image and a preset standard image, a position correction value for the projection onto the target reflecting surface;
• and
• correct, based on the position correction value, a target image to be projected by a projection device to acquire a corrected image projected onto the target reflecting surface.

A method for correcting a projected image, comprising:

• generating a first capturing frame and a second capturing frame surrounding a periphery of the first capturing frame, wherein a capturing region is formed between the first capturing frame and the second capturing frame;
• capturing a test image when edges of the test image are located within the capturing region to acquire a template image, wherein the test image is an image projected by a projection device onto a target reflecting surface;
• and
• sending the template image to the projection device, wherein a deviation between the template image and a preset standard image is used for determining a position correction value for projection onto the target reflecting surface, and the position correction value is used for correcting a target image to be projected by the projection device to acquire a corrected image on the target reflecting surface.
