The application discloses an operation guidance method and system based on widescreen splicing, and a computer-readable storage medium. The method includes starting the widescreen projection system and after the two optical machines focus on the projection, if it is detected that the user triggers the operation through the setting interface or through voice information For projection calibration, control the projection surfaces of the two optical machines to the shooting direction of the camera, and project the splicing calibration images respectively; based on the captured images of the splicing calibration images captured by the camera, determine the positional relationship between the two splicing calibration images; according to the positional relationship, generate and Output the operation guide of the optical machine; after the two splicing and calibration images are seamlessly stitched, the two optical machines perform keystone correction and projection size correction; finally control the two optical machines to project the images to be displayed on the projection surface. The present application avoids the problem of large upper and lower black borders in the projection of the widescreen projection system, and the small projected area of the actual display image, and improves the overall effect of the effective projection picture of the widescreen projection system.
Description
technical field [0001] The present application relates to the technical field of projection display, and in particular to an operation guidance method, system and computer-readable storage medium based on widescreen splicing. Background technique [0002] With the development of science and technology, projection equipment is becoming more and more popular in offices, multi-functional meeting rooms, and home theaters. At present, projection equipment or projection systems generally use a single optical machine to output a single optical path for projection. In the projection direction, its projection area is limited by Limitations in projection distance, physical characteristics of optomechanical imaging, and image keystone correction. [0003] When the above-mentioned projection equipment or projection system is in the case of side projection, due to the influence of trapezoidal correction factors on the screen, the actual displayed projection image will be scaled down and ...
