The invention discloses a geometric correction method and apparatus, and a laser projection device. The method comprises the steps of obtaining a to-be-projected image frame sequence; in response to the image processing starting instruction and the image processing ending instruction, adding a correction identifier to an image frame sub-sequence in the image frame sequence within a time range corresponding to the image processing starting instruction and the image processing ending instruction to obtain a processed image frame sub-sequence; projecting the processed image frame sub-sequence to a screen through the host, and in response to an image processing start instruction, triggering a camera to capture a projection area of the laser projection equipment to obtain a shot image corresponding to the processed image frame sub-sequence; and in response to an image processing ending instruction, performing geometric correction on a subsequent to-be-projected original image of the processed image frame sub-sequence based on the position of the correction identifier in the shot image. According to the embodiment of the invention, geometric correction is completed without perception of a user, and user experience is improved.
Description
technical field [0001] The present application relates to the technical field of laser projection, in particular to a geometric correction method, device, and laser projection equipment. Background technique [0002] Laser TV and micro-projection products adopt laser light source and ultra-short-focus projection technology for imaging. Laser TV is equipped with a special projection screen, which can receive broadcast TV programs or Internet TV programs. Micro-projection products are small in size, easy to carry, and quickly project images, are widely used. [0003] The position of the host and the screen does not match during the installation of the laser TV, or the host is passively shifted during the use of the laser TV, which may cause the projection screen to not completely match the screen. Laser TVs usually use the automatic geometric correction function to solve the above problems. However, in related geometric correction solutions, users are required to perform corr...
