摘要： A method for projecting an image onto a front projection screen without the image being projected onto a presenter and without the presenter casting a shadow. Left and right rectilinear corrections of an image are simultaneously projected onto the screen from each of two positions that are off-axis on opposite sides of the centerline of the screen such that both projections register as a single image. A center of mass of the presenter's silhouette is generated. A vertical join line is located on the screen directly behind said presenter's center of mass. The portion of the projected image from the left projector that extends to the right of the join-line is inhibited. The portion of the projected image from the right projector that extends to the left of the join-line is also inhibited thereby providing the full projected image on the screen from the left and right image segments, without either segment projecting said image onto the presenter, and without casting the presenter's shadow onto the screen.
摘要翻译：一种用于将图像投影到前投影屏幕上而不将图像投影到演示者上而不呈现者投射阴影的方法。图像的左右直线校正同时从屏幕中心线的相对侧的离轴两个位置中的每个位置投影到屏幕上，使得两个突起都注册为单个图像。演示者剪影的质心是生成的。垂直连接线位于显示器的质心之后的屏幕上。来自左侧投影机的投影图像的延伸到连接线右侧的部分被禁止。来自右投影仪的延伸到连线的左侧的投影图像的部分也被禁止，从而从左和右图像段在屏幕上提供全投影图像，而无需将所述图像投影到演示者上，并且不会将演示者的阴影投射到屏幕上。
