Geometry adjustments for seamless edge blending precise geometry adjustment), the second is image consistency (i.e. With them, image blending would be much easier conversely, it would be impossible to overcome certain issues if some of the criteria are not met, such as resolution or lens differences.Īside from calculation for spacing between installations and projection size for stitching, there are two main factors for a successful multi-projection, the first is seamlessness (i.e. This can be considered a priori criteria necessary for a successful multi-projection setup. The best way to achieve parameter consistency such as brightness and color etc., is to choose machines from the same batch of production, with similar parameter configurations. (4) Similar color parameters, pick specific configurations including color temperature and chromaticity coordinates. (3) Similar brightness, machines with near the same hours of use Projection brightness will deteriorate as hours of use increases (2) Same throw ratio and lens with the same focal length range
