摘　　要：目前各展馆使用多机展示时,常存在投影重叠区域亮度过高,投影图像不清晰的问题,因此设计以激光投影器作为基础的影视动画多机展示方法。构建一个多投影模块的主从设备模式结构,该结构先在主投影模块将多投影模块配置程序启动,初始化从投影模块并接受绘制指令,然后计算对应投影模块视景;主投影模块发出绘制命令,从投影模块先使用激光陈列仪得到激光投影器的投影矩阵,在此基础上使用Alpha融合拼接技术与Gamma校正方法实现亮度调整与色彩融合,完成图像信息绘制,主投影模块接受这些图像信息将交换前后台缓冲区指令发送给从投影模块,最终多机输出同步视景。通过实验分析,该方法具有良好的多机展示效果,能够有效解决投影重叠区域过亮的问题,且色彩融合速度快,投影图像效果清晰,适合广发推广。At present,there is often a problem that the projection overlapping area is too bright,and the projection image is not clear.Therefore,the multi-machine display method of film and television animation based on laser projector is designed.Construct a multi-node master-slave device mode structure,which starts the multi-channel configuration program at the master node,initializes the slave node and receives the drawing instruction,and then calculates the corresponding channel view.Master node drawing commands,laser display is used to get from the node first laser projector projection matrix,based on the use of Alpha fusion splicing technology and Gamma correction methods to realize brightness adjustment and color fusion,complete the image information,the master node to accept these images information exchange to Taiwan before and after buffer commands sent to the slave node,eventually more machine visual output synchronization.Through the experimental analysis,this method has a good multi-machine display effect,can effectively solve the problem of over-bright projection overlapping area,and color fusion speed,projection image effect is clear,suitable for widespread promotion.
