The higher the warping resolution (more grid blocks), the higher the amount of precision one can achieve, for a better seamless effect.Ģ. Aside from basic adjustment of the four corners, it also need to be able to freely adjust any regions within the projection, that way, it would be able to support edge blending of not only regular rectangle outputs, but also irregular shaped outputs such as arcs, columns etc. (1-2) In terms of geometry positioning, there are two methods in general, external software or built-in image warping/edge blending processor. By comparison, automatic adjustment offers not only higher precision and reliability, but also speedy geometry adjustment, which is convenient and saves time. ![]() #EDGE BLENDING SOFTWARE FREE MANUAL#There are two ways to adjust them, the first one is manual adjustment, which is a knob for Lens Shift, and a ring for Zoom, the second one is automatic adjustment. ![]() (1-1) Optical Alignment, adjustment of the Lens Shift and Zoom of lens increases the precision and flexibility of projection locations. 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 ![]() DS2 units are able to run standalone without the connection to the control PC, once configured.(2) Same throw ratio and lens with the same focal length range #EDGE BLENDING SOFTWARE FREE WINDOWS#The Windows based software provides a user friendly GUI, greatly simplifying the system configuration. #EDGE BLENDING SOFTWARE FREE PC#The bonus of having the 4K media player built in is that the user does not need to worry about adding extra devices to their project.ĭS2 units can be easily configured via IP connection or RS232 to a Windows based PC running SEADAs management software. Moreover, DS2 also has an embedded 4K media player which enables DS2 to output a 4K video source played locally in addition to two captured HDMI video sources. In addition to its edge blending ability at the output sides, DS2 is able to capture one HDMI video source and display that onto the projection screen anywhere and any size. SEADA provide two different versions of the DS2, one with 3 HDMI outputs and another with 9 HDMI outputs. It is not only able to blend up to nine projectors together into one flat seamless display but also able to warp geometries on non-standard surfaces to form a curved or spherical projection surface. The DS2 is the device from SEADA that combines an edge blender, video wall controller and a 4K media player together in one unit. ![]()
