Photon switching technology is a fundamental solution to the speed unmatch between optical fibre system with high transmission speed and electronic switching system with slow switching speed .

光子交换技术是解决高速的光纤传输系统和低速的电子交换系统之间速度 失 配的根本 措施。

The actual reasons behind is the lack of description from the objective model for the nature target so when the target posture changes or occlusion occurs it will bring the unmatch between the target model and the non-linear changes in target appearance .

其背后的原因为目标模型缺少对目标本质 特征的刻画，因此当目标发生姿态变化或 遮挡时，就会带来目标模型 无法与目标表观上的非线性变化 相匹配。
