An object-based integrity verification method (330) for detecting hazardously misleading information contained in an output image of a graphics processing unit comprises steps of: identifying a plurality of safety-critical graphic objects in the output image (332); assigning each safety-critical graphic object an object ID code (334); creating an object verification database (336); rendering a monochrome reference ID code image using object ID code as its color component (342T.1 and 342C.1); verifying the location, shape and color information for each safety-critical graphic object (342S.4, 342T.5 and 342C.6), and tracking the visibility and overlaying property between safety-critical graphic objects using the monochrome reference ID code image (342T.5 and 342C.6); detecting and evaluatingfailure condition (346); and annunciating the failure condition with proper warning level and appropriate corrective action (350).

    一种基于对象的完整性验证方法(330),用于检测包含在图形处理单元的输出图像中的危险误导性信息,包括以下步骤:标识输出图像中的多个安全关键图形对象(步骤332);为每个安全关键图形对象分配一个对象ID代码(步骤334);创建一个对象验证数据库(步骤336);使用对象ID代码作为颜色成分来渲染一个单色参考ID代码图像(步骤342T.1和步骤342C.1);验证每个安全关键图形对象的位置、形状和颜色信息(步骤342S.4、步骤342T.5及步骤342C.6),并使用上述单色参考ID代码图像来跟踪安全关键图形对象之间的可见性和重叠属性(步骤342T.5及步骤342C.6);检测和评估故障状况(步骤346);并在通告故障状况的同时提供适当的警告级别和适用的纠正措施(步骤350)。
