An intersection warning system and method based on information fusion, the system comprising a road mouth sensing device, an intersection computing device, a user device and a cloud server, the cloud server receiving and storing a spot sensing information output by the road mouth sensing device from the intersection computing device, determining whether to receive a user positioning coordinate from the user device; if yes, the cloud server reads the scene sensing information and at least one piece of background information, and calculates a fusion risk assessment value according to the scene sensing information, the at least one piece of background information and a plurality of weight values; when the cloud server judges that the fusion risk assessment value is larger than a threshold value, the cloud server outputs a warning instruction to the user device, and the user device sends a warning message according to the warning instruction.
一种基于资讯融合的路口警示系统与方法,该系统包含一路口感测装置、一路口运算装置、一使用者装置与一云端服务器,该云端服务器从该路口运算装置接收并储存该路口感测装置所输出的一现场感测资讯,并判断是否从该使用者装置接收一使用者定位坐标;若是,该云端服务器读取该现场感测资讯和至少一后台资讯,并根据该现场感测资讯、该至少一后台资讯和多个权重值计算出一融合风险评估值;该云端服务器于判断出该融合风险评估值大于一阈值时,输出一警示指令给该使用者装置,该使用者装置根据该警示指令发出一警示讯息。
