The application discloses an automatic curved
surface projection correction splicing method, first, a
network camera driving module is run, file mapping technology is used to transmit image information with a main program, then a curtain calibration point is recognized according to a specific color. After that, through an
iterative method, in each round of iteration, a core
algorithm is used to update
distortion parameters according to a projection calibration diagram collected by a camera until a termination condition is reached and then the method is stopped. Finally, according to the
distortion parameters obtained through iteration, a final corrected image is obtained. After
distortion correction, taking an intermediate channel image as a reference, an iterative splicing
correction method is used in left and right channels to complete splicing correction. Finally, in order to eliminate the bright band caused by splicing,
color transition is performed on the image. The application does not depend on the accurate position relationship between the camera and the
projector, the model can automatically iterate to complete
distortion correction and splicing work, and manual participation is not needed, so that the problems of low precision and long time consumption in manual correction are solved, and the application has good correction, splicing and
color transition effects.
