MULTI-PROJECTION SPLICING GEOMETRIC CALIBRATION METHOD AND CALIBRATION DEVICE

摘要

Provided is a multi-projection splicing geometric calibration method and calibration deviceThe method includes obtaining the mapping relationship between a camera and a 3D arc screen; according to the mapping relationship between a projector and the camera, the mapping relationship between the camera and the 3D arc screen and the mapping relationship between the 3D arc screen and an inputted super high resolution image, obtaining a projector frame buffer image transformation mapping table; and, according to the projector frame buffer image transformation mapping table, performing geometric rectification calibration on an image to be projected by the projector.The present invention can calibrate in a simple and effective way.
