未来坐地铁可刷脸进站

上海申通地铁集团与阿里巴巴、蚂蚁金服12月5日联合宣布,三方达成战略合作,阿里巴巴最新研发的语音购票、刷脸进站、智能客流分析等多项技术首度惊艳亮相。虽然这些技术刚刚完成实验室测试,进入样机研制阶段,但是都将逐步应用于上海地铁。

上海地铁建设的“METRO大都会”App将引入阿里的技术,方便上海老百姓出行。预计明年初,上海地铁就将支持App扫码过闸,并支持支付宝付款。

1个多月前,上海就在磁悬浮线路上首先试点了扫码进站。上海地铁计划在明年初,在全市17条轨交线路全面推广扫码进站。乘客只需要在“Metro大都会”App中一键绑定支付宝,就可以扫乘车码进站,出站时再扣除车费,无需兑换零钱和排队购票。支付宝方面表示,即使在没有网络信号或者支付宝账号内没有余额的情况下,乘客也可以先进站乘地铁,后续再支付车费。

未来,用户可能连手机都不用掏出来,仅靠刷脸,就可以直接进站。在研发中的新型进站闸机上,新增有一块屏幕,用户经过屏幕时,几乎无需停留,屏幕就已依托阿里巴巴人脸识别技术,完成了人脸识别,开启闸机,供乘客通过。

在达成战略合作后,阿里巴巴将成为上海地铁最重要的互联网技术合作伙伴。除了移动支付、人脸识别技术,阿里巴巴此次还展现了另外两项前沿技术——多模态智能语音交互技术和智能客流分析技术。

前者首先应用在地铁语音售票机上,以往乘客需要清楚知道目的地在哪条线路、哪个站点才能自助购票。将来,利用模糊查询方式,只需通过语音对售票机说出目的地,如“我要去东方明珠”,售票机会自动推荐坐哪条线路、到哪一站下车,乘客扫码或刷脸支付即可完成购票,全程不过数秒钟时间。

阿里巴巴DST资深人工智能专家鄢志杰表示,传统的语音交互都是在家庭、车内等安静环境下实现的,语音售票机是业内首个能在地铁这种公共嘈杂环境下,实现精准远距离语音交互的产品。“我们深度融合了语音信号处理和计算机视觉技术,解决了强噪声干扰问题。售票机甚至可以在用户靠近时主动发起交互,无需用户唤醒。”据悉,此类“下一代人机交互”技术正是阿里巴巴达摩院首批公布的重点研究方向之一。

智能客流分析技术则能基于视频识别技术,替代肉眼,分析车站的客流速度、密度、拥挤指数等,同时结合地铁列车运营信息、外部天气信息等,预测未来流量变化,帮助地铁工作人员疏导客流、应急调度、危险防范等,保障乘客安全。

上海地铁是目前全球运营里程最长的城市轨道交通网络,相信引入阿里巴巴和蚂蚁金服技术后,未来的上海地铁,还将是全球最先进、最具有科技含量的地铁,从而惠及更多的乘客。(李治国)
