The invention discloses a method for determining the calibration parameter of a 3D display device and the 3D display device. The method comprises a step of selecting a first calibration parameter from a preset calibration parameter range, generating a first interleaving parameter through a preset interleaving algorithm, carrying out interleaving processing on a preset characteristic image according to the first interleaving parameter and then projecting the image to the outside to form first projection, and obtaining the first projection image of the projection, a step of adjusting the calibration parameter and obtaining a second projection image, a step of analyzing the fringe cohesiveness of the two projection images, and storing a projection image with higher fringe cohesiveness, and a step of executing the above steps until a projection image with highest fringe cohesiveness is obtained, and storing a corresponding correction parameter. The invention discloses the method for determining calibration parameter of a 3D display device, the influence of a fitting error of a 3D module and a camera assembly error on 3D display can be reduced, the calibration is automatically completed, and the 3D display effect can be improved.
Description
technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a method for determining calibration parameters of a 3D display device and the 3D display device. Background technique [0002] In recent years, with the continuous maturity of 3D technology, the 3D display industry has developed rapidly, and various 3D display products have been introduced to the market, providing people with better visual effects. In order to obtain a good 3D display effect, the bonding of 3D modules Accurate alignment is required, and expensive equipment is required to complete it. However, when 3D display products are attached to 3D modules or cameras are installed, errors may occur, or during use, collisions may cause 3D modules or cameras to shift, etc., which will cause 3D display products to perform 3D display It will be very blurred, and the poor look and feel will seriously affect the scope of use of 3D display products, and the user exper...
