背景技术
增强现实 (英文: Augmented Reality, 缩写: AR) 是一种用于帮助 人们以更直观、 更形象的方式获取关于现实世界中物体的相关信息的技 术。 AR系统的工作流程分为感知、 识别、 匹配及渲染四个步骤。
现有的地图应用可为用户提供基于位置的兴趣点 (英文: Point of Interest, 缩写: POI ) 的查询服务。 安装了该地图应用的终端首先使用 全球定位系统 (英文: Global Position System, 缩写: GPS) 或者蜂窝 网的小区标识 (英文: Cell ID) 确定用户的当前位置 (经纬度) , 然后 根据该当前位置查询数据库, 再从数据库中获取该当前位置附近已经注 册的餐厅、 银行、 商场及车站等 P0I; 用户也可在地图应用中输入一个 其感兴趣的位置, 而该地图应用通过搜索数据库, 并在地图上定位该位 置, 从而搜索到该位置附近的 P0I。 现有的问答系统在接收到用户输入 的问题和相应的数据, 并对该问题进行自然语言处理后, 将该问题传送 至查询子系统, 查询子系统推断该问题的答案, 并从知识库中取出相关 的答案输出给用户。
然而, 上述地图应用要求用户对自己请求的 P0I 具有明确的认识, 即用户需要根据自己的需求分析出自己想要到达的 P0I; 上述问答系统 只能处理单一类型的文本数据, 不能处理复杂类型的数据, 且若用户输 入的问题不够精确, 该问答系统则无法满足用户的信息需求。

如图 3所示, 本发明实施例提供一种筛选 AR内容的方法, 该方法可 以包括: 5301、 终端读取第二目标的标签信息, 并根据第二目标的标签信息 获取第二目标的标识。 当用户需要获知某个物体或产品的信息时, 用户首先可通过终端按 照拍照、 扫描或读标签等方式读取第二目标的标签信息, 并根据第二目 标的标签信息获取第二目标的标识, 其中, 第二目标为终端所在环境中 设置了可读标签的物体。
5302、 终端发送携带第二目标的标识的第三请求消息至服务器。 终端获取第二目标的标识后, 终端可将该第二目标的标识携带在第 三请求消息中发送至服务器。 其中, 第二目标的标识可以包括第二目标 的名称、 第二目标的类型或第二目标的品牌中的至少一种。
5303、 服务器根据第二目标的标识查找到第二目标的位置信息。 服务器接收到来自终端的第二目标的标识后, 服务器可根据第二目 标的标识在服务器中预先保存的信息中查找到第二目标的位置信息。 具 体的, 第二目标的位置信息可以包括第二目标的坐标值。
需要说明的是, 第二目标的位置信息可通过预先收集的室内地图及 第二目标的数据所得。 由于在购物中心、 超市、 图书馆、 博物馆、 机场、 车站等公共场所内, 存在着大量贴有可读标签的物体, 并且随着 NFC标 签成本的下降, NFC 智能海报也将得到广泛的应用, 因此, 可读标签在 公共场所会越来越丰富。 为了便于对商品、 图书等物品的管理, 商场、 图书馆等场所的工作人员在整理这些物品时需记录这些物品所在的区域 或位置。 目前, 室内地图一般也是由这些场所的工作人员上传到地图应 用服务提供商的。 因此, 在整理和布置室内环境时, 工作人员可以把带 有可读标签的物体, 即第二目标在室内地图上的位置信息记录下来并保 存到服务器, 这是收集室内地图和第二目标的数据的一种实现方式。
收集第二目标的位置信息还有另外一种方法, 在室内环境中, 例如 购物中心、 图书馆等, 用户可以使用自己的手机、 头戴式设备或者其他 移动设备读取第二目标的可读标签, 如条形码、 二维码或 NFC标签等, 获取该第二目标的编号并向服务器请求该第二目标的相关信息; 与此同 时, 可以提供一种包含用户所在环境的室内地图的应用, 以某种奖励的 方式鼓励用户把扫描到的第二目标的位置信息标识在室内地图上, 从而 第二目标的位置信息将被保存到服务器上, 通过这种方式不仅可以收集 第二目标的位置信息, 还可以修正已经收集到的第二目标的位置信息。 可选的, 服务器还可根据第二目标的标识在服务器中预先保存的信 息中查找到第二目标的描述信息, 以用于为用户提供第二目标的材料、 第二目标的产地、 第二目标的价格及其他用户对第二目标的评论等相关 信息。 其中, 第二目标的描述信息可用于帮助用户获知其查看的产品的 相关信息。
本发明实施例提供的终端所在的室内环境中存有大量的可读标签或 者可以与终端进行交互的信息设备, 且这些可读标签及信息设备的位置 都已经在室内地图上标识出来并保存在了服务器中。
S 304、服务器返回携带第二目标的位置信息的第三响应消息至终端。 服务器查找到第二目标的位置信息后, 服务器可将该第二目标的位 置信息携带在第三响应消息中发送至终端, 即终端获取到第二目标的位 置信息。
S 305、 终端发送第一记录事件至服务器, 其中, 第一记录事件包含 终端读取第二目标的标签信息的行为。
终端读取第二目标的标签信息之后, 终端发送第一记录事件至服务 器, 其中, 第一记录事件可以包含终端读取第二目标的标签信息的行为。
具体的, 当终端读取第二目标的标签信息或者与第二目标发生信息 交互时, 终端会自动记录该事件 (即第一记录事件) , 并会发送该第一 记录事件至服务器, 该第一记录事件触发服务器保存并分析该第一记录 事件, 其中, 该第一记录事件可以包含终端的行为 (如终端读取第二目 标的标签信息、 终端与第二目标发生信息交互等) 。
进一步地, 第一记录事件还可以包含第二目标的位置信息, 在终端 接收到来自服务器的第二目标的位置信息后, 终端将终端读取第二目标 的标签信息的行为和第二目标的位置信息作为第一记录事件同时发给服 生的位置, 即第二目标的位置信息, 这里由于是终端读取第二目标, 因 此第二目标的位置信息与此时终端的位置信息相同。 可以理解的是, 终端向服务器发送第一记录事件时, 服务器可根据 该终端的标识获取到该终端的位置信息。
需要说明的是, 若终端向服务器发送的第一记录事件不包含第二目 标的位置信息, 则本发明不限制 S302-S304和 S305的执行顺序, 即本发 明可以先执行 S302-S304, 后执行 S305; 也可以先执行 S305, 后执行 S302-S304; 还可以同时执行 S302-S304和 S305。
S306、 服务器根据终端的标识和终端的位置信息对第一记录事件进 行分类并确定第一记录事件的概率。
服务器接收到终端发送的终端的标识、 终端的位置信息及第一记录 事件后, 服务器可根据终端的标识和终端的位置信息对第一记录事件进 行分类, 并根据大数定律计算出每一类第一记录事件发生的概率, 其中, 大数定律是一种描述当试验次数很大时所呈现的概率性质的定律。
具体的, 终端的标识可以是终端上的用户身份识别卡 (英文:
Subscriber Identity Module, 缩写: SIM) 号码, 也可以是终端的国 际移动设备序歹 ij号 (英文: International Mobile Equipment Identity, 缩写: IMEI ) 等其他满足要求的标识, 本发明不做限制。 终端的位置信 息可以包括终端的坐标值。
举例来说, 用户在某个电影院内使用二维码从自动售票机上兌换电 影票、 用户在售票处使用移动支付现场购买电影票, 或者用户在会员服 务中心购买爆米花并使用 NFC移动支付功能付款等, 终端会将这些事件 记录为第一记录事件并发送至服务器, 服务器在接收到终端发送的这些 第一记录事件后, 按照自动售票机 /售票处 /会员服务中心的标识, 或自 动售票机 /售票处 /会员服务中心的位置信息, 或自动售票机 /售票处 /会 员服务中心的标识, 及自动售票机 /售票处 /会员服务中心的位置信息对 这些第一记录事件进行分类。 又如, 用户使用二维码兌换电影票时, 可 使用电影票兌换终端或电影院官方的自动售票机进行兌换, 而这一类使 用不同兌换终端兌换电影票的第一记录事件都可以被服务器分为同一类 第一记录事件。 当服务器记录了大量第一记录事件后, 服务器可根据大 数定律计算出每一类第一记录事件发生的概率。 上述兌换电影票的例子 中, 服务器可根据终端已发生过的行为, 计算出用户在进入电影院后, 在售票处使用移动支付现场购买电影票的概率及使用二维码从自动售票 机上兌换电影票的概率。
本发明实施例中, 第一记录事件发生的概率可以表示为第一记录事 件在第二目标的位置发生的概率。
需要说明的是, 终端及服务 ¾可以重复执行 S301 至 S306, 以记录 更多的事件及保存大量的数据, 如用户逛商场时, 可以使用终端读取多 个第二目标的标签信息, 并将读取该第二目标的标签信息的行为记录为 第一记录事件发送至服务器。
S 307、 当终端中获取位置信息的应用被触发时, 终端拍摄终端所在 位置的全景照片, 并根据该全景照片确定终端的位置信息及第一目标的 相关信息。
当用户在室内环境迷路或者不能确定自己的行为时, 用户可触发终 端中的获取位置信息的应用。 即当终端中获取位置信息的应用被用户触 发时, 终端可拍摄终端所在位置的全景照片, 终端根据该全景照片确定 终端的位置信息及第一目标的相关信息。 其中, 终端根据终端拍摄的全 景照片确定第一目标的相关信息的技术可以包括: 光学文字识别技术、 图像识别技术等。
示例性的, 第一目标是指终端所在室内环境中存在的、 可以使用图 像处理方法识别的对象, 也就是 AR 目标; 同时, 在服务器中保存有一个 预设的目标库, 该目标库中存储了该环境中的多个目标, 该目标库也可 以预先从服务器下载至终端, 由终端保存。 例如, 第一目标可以为终端 所在室内环境的方向指示箭头、 店铺标识、 消防标志、 电梯对象中的一 种。 AR内容可以包括图文信息、 视听信息、 3D图像等。 本发明实施例中 的 AR内容中可以包括一个分类信息 (该分类信息可以表示为图文信息、 视听信息、 3D 图像等) , 该分类信息用以表示该 AR 内容与用户的哪一 种行为相关, 例如, 一组 AR内容的分类是导航类, 该组 AR内容可用于 指示被选定的第一行为是用户前往某个特定的目的地。
特别的, 第一目标的相关信息可以包括第一目标的图像特征值、 第 一目标的位置信息等。 其中, 第一目标的相关信息可以是由终端在 S 1 01 之前预先收集的数据; 第一目标的位置信息可以包括第一目标的坐标值。
具体的, 终端确定第一目标的位置信息的方法可以为下述的一种:
( 1 )终端拍摄终端所在位置的全景照片后, 终端对该全景照片进行 图像处理, 并对比该全景照片中提取到的对象的特征值与终端中保存的 预设的第一目标库中的第一目标的特征值, 若第一目标库中存在与该全 景照片中提取到的对象的特征值相同的对象, 那么终端可确定在该全景 照片中发现了第一目标, 进而可以确定第一目标的位置信息, 这是由于 第一目标的位置信息与第一目标的图像特征是关联在一起的。 ( 2 )终端拍摄全景照片, 并根据基于视觉的室内定位算法确定终端 所在的位置, 从而终端搜索此终端所在位置附近可能存在的可识别的第 一目标, 进而根据这些第一目标获取到这些第一目标的位置信息, 这是 由于这些第一目标的位置信息是提前预设保存在终端中的。
需要说明的是, 本发明实施例提供的筛选 AR内容的方法中, 在服务 器中保存有一个预设的第一目标库, 此第一目标库也可以预先下载到终 端; 第一目标及其相关的图像特征值、 位置信息等是有意识的预先收集 的, 在部署应用之前就可以收集这些数据。
进一步地, 终端还可以通过其他能够显示终端所在环境的方式确定 该终端的位置信息及第一目标的相关信息, 本发明不做限制。
S 308、 终端发送第一请求消息至服务器, 第一请求消息中携带终端 的标识及终端的位置信息。
终端确定终端的位置信息后, 终端发送第一请求消息至服务器, 其 中, 第一请求消息中携带终端的标识及终端的位置信息。
S 309、 服务器根据终端的标识、 终端的位置信息及不同行为的条件 概率确定至少一个行为。
服务器接收到终端发送的第一请求消息后, 服务器可根据第一请求 消息中携带的终端的标识、 终端的位置信息及服务器之前统计并计算的 不同行为的条件概率, 按照这些不同行为的条件概率的大小以及预设的 概率门限值确定至少一个行为。
可以理解的是, 上述服务器得到的至少一个行为可以为一个事件集 合, 该事件集合可以由程序开发者根据大多数用户日常发生的一些行为 (例如用户寻找银行、 餐馆、 超市等) 初始化所得。 在本发明实施例提 供的筛选 AR内容的方法中,服务器还可以收集并分析使用该终端的用户 的说明。
S 31 0、 服务器发送携带至少一个行为的第一响应消息至终端。
服务器得到上述的至少一个行为后, 服务器将该至少一个行为携带 在第一响应消息中发送至终端。
S 31 终端在确定至少一个行为中的第一行为被选定时, 发送第二 请求消息至服务器, 第二请求消息中携带第一行为的信息。 终端接收到服务器发送的至少一个行为后, 终端将该至少一个行为 呈现给用户, 用户可根据自己的需求在该至少一个行为中选择一个满足 自己需求的行为, 即第一行为。 当终端确定至少一个行为中的第一行为 被选定时, 终端可发送第二请求消息至服务器, 其中, 第二请求消息中 携带第一行为的信息。
本领域普通技术人员可以理解, 至少一个行为或第一行为呈现在终 端上显示为锚链文本(英文: archor text)形式, 锚链文本是指带有统一 资源定位符 (英文: Uniform Resource Locator, 缩写: ) 链接的文 本, 即当用户点击或触摸某一段文本时, 可以触发访问一个 URL链接。
S312、 终端发送第二记录事件至服务器, 第二记录事件包含至少一 个行为中第一行为被选中的行为。
终端确定至少一个行为中的第一行为被选定时, 终端发送第二记录 事件至服务器, 其中, 第二记录事件包含至少一个行为中第一行为被选 中的行为。
可选的, 第一目标的相关信息包括第一目标的位置信息, 其中, 第 二记录事件还包含第一目标的位置信息。 终端获取到第一目标的位置信 息后, 终端将至少一个行为中第一行为被选中的行为和第一目标的位置 信息作为第二记录事件同时发给服务器。 其中, 此时第二记录事件可以 包含至少一个行为中第一行为被选中的行为以及终端从全景照片中确定 的第一目标的位置信息。
需要说明的是, 本发明不限制 S311和 S312的执行顺序, 即本发明 可以先执行 S311后执行 S312, 也可以先执行 S312后执行 S311, 还可以 同时执行 S311和 S312。
S313、 服务器根据终端的标识和终端的位置信息对第二记录事件进 行分类并确定第二记录事件的概率及第二记录事件的条件概率。
服务器接收到终端发送的第二记录事件后, 服务器可根据终端的标 识和终端的位置信息对第二记录事件进行分类, 并根据大数定律计算出 每一类第二记录事件的概率, 以及根据第一记录事件的概率、 第二记录 事件的概率确定第二记录事件的条件概率, 即第一记录事件发生的条件 下, 第二记录事件发生的概率。 其中, 本发明实施例提供的筛选 AR内容 的方法中, 可将第一记录事件发生的频率记为第一记录事件的概率; 将 第二记录事件发生的频率记为第二记录事件的概率。
本发明实施例中, 第二记录事件的条件概率可以为第二记录事件在 第一记录事件发生的条件下发生的概率。 具体的, 服务器在已获知第二 记录事件发生的条件下, 可再统计该条件下第一记录事件发生的概率, 即第一记录事件的条件概率, 并根据第一记录事件的条件概率, 第一记 录事件的概率, 及第二记录事件的概率, 通过贝叶斯公式计算得到第二 记录事件的条件概率, 即第一记录事件发生的条件下, 第二记录事件发 生的概率。
可以理解的是, 对于多类第一记录事件和多类第二记录事件, 可以 计算出每一类第一记录事件发生的条件下, 有可能发生的每一类第二记 录事件发生的概率, 即上述的不同行为的条件概率。
特别的, 下面对计算不同行为的条件概率的方法及过程进行详细地 说明。
贝叶斯定理是概率论中一条重要的定理, 后验概率 I 和先验概 率 ρ μ )的关系可以表示为:
Ρ{Α\Β)=Ρ{Α) Ρ(Β ] Α)
; 、 ' Ρ(Β)
其中,事件 S是观测到的事件,事件 是可能导致事件 S发生的事件。 在事件 ^已经发生的条件下, 假设可能发生的后续事件 S = f/^^. , 事件集 B} ( =1, 2, .. ) 中每一个 的概率为 根据贝叶斯定理可以得 到在给定事件 4已经发生的条件下,任何事件 发生的概率, 即事件 的 条件概率为:
Ρ(Β] \Α) = Ρ(Β]) ^
Ρ(Α)
由上述公式可以看出, 根据贝叶斯定理, 已知事件 4、 事件 s发生的 概率和事件 s发生时事件 4发生的概率, 则可以计算出事件 4发生的条件 下, 事件 S发生的条件概率。
假设服务器保存的第一记录事件的集合为(4 , = 1, 2, ... , Ν、 其 中, 4表示第 ζ·类第一记录事件, 类第一记录事件的并集 ί^4. = , 则 服务器可以计算出第 类第一记录事件发生的概率 又假设服务器保 存的第二记录事件的集合为 { , = 1, 2, ... , M) , 表示第 ·类第二记 录事件, M类第二记录事件的并集 ^/^„Ω, 则服务器可以计算出第 _/类 第二记录事件发生的概率 P(^); 当服务器接收到第二记录事件的数量不 够多时, 可假设第二记录事件 为等概率事件。
服务器根据终端标识进行统计, 可以得到某个终端做过第一记录事 件 4之后执行第二记录事件 的样本, 从而从足够的样本中计算得到第 二记录事件 发生的条件下, 第一记录事件 4发生的概率为 P(A, | .)。
根据贝叶斯公式, 可以计算得到第一记录事件 4发生的条件下, 第 二记录事件 发生的条件概率为:
Ρ(ΒΛΡ(Α \ΒΛ
Ρ(Β, \ Α)= 'J ' ' JJ
P(At)
进一步地, 如果同一个终端在向服务器发送请求消息之前, 服务器 保存的该终端上报的第一记录事件分别为 4和 4,假设用户通过该终端选 择某条帮助信息的行为, 即第二记录事件 记为事件 , 该用户未选择 某条帮助信息的行为记为事件 £2, 则如表 1所示:
表 1
Figure imgf000023_0001
由表 1可 口, 表示 4、 4发生之后, 发生; £2表示 4
后, 未发生。 假设 4、 4是独立事件, 则可得表 2:
表 1
Figure imgf000023_0002
综上, 在 4、 4发生之后, 发生的概率可以通过如下公式计算得 p=. Ρ(ΕΛ)
Ρ(ΕΛ) + Ρ(Ε2)
Ρ(Β} I ΑΛ )Ρ(Β} I Α2 )Ρ(Β} ) + (1 - Ρ(Β} | ΑΛ ))(1 - Ρ(Β} | Α2 ))(1 - Ρ(Β} )) 由此可以计算出当某个用户通过终端连续被记录做了 4、 4两件事 之后, 该用户希望获得某条帮助信息的行为 的概率 即不同行为的 条件概率, 从而服务器可根据该不同行为的条件概率中最大的条件概率 得到用户最有可能发生的至少一个行为。 且服务器将服务器得到的该至 少一个行为发送至终端, 从而终端可将该至少一个行为呈现给用户, 以 便于用户选择自己所需的某个行为, 进而根据该行为获取帮助信息。
5 31 4、服务器发送携带与第一行为对应的 AR内容的第二响应消息至 终端。
服务器接收到终端发送的第二请求消息后, 服务器可根据第二请求 消息中携带的第一行为的信息在服务器中预先保存的 AR 内容中筛选出 与第一行为对应的 AR 内容, 并将该 AR内容携带在第二响应消息中发送 至终端。
5 31 5、 终端根据第一目标的相关信息, 将第一目标和与第一行为对 应的 AR内容结合后呈现。
终端接收到服务器发送的与第一行为对应的 AR内容后,终端可根据 第一目标的相关信息, 将第一目标和该 AR内容结合后呈现。 例如, 终端 将从终端拍摄的全景照片中确定的某个显著标志物与服务器中预先保存 的该显著标志物的 AR内容结合后呈现出来,从而以使得用户可根据终端 呈现的显示结果获取到达该显著标志物的路线, 进而到达该显著标志物 所处的位置。
需要说明的是,终端结合呈现第一目标和与第一行为对应的 AR内容 的方式可以为配准显示或未配准显示。 其中, 配准显示是指计算机生成 的内容与物理世界中的某个对象对准且合并为统一的场景呈现给用户; 未配准显示则是指计算机生成的内容与物理世界中的某个对象未对准, 而只是简单的叠加后呈现给用户。 具体的, 当终端发送至服务器的第二 记录事件中包含第一目标的位置信息时, 终端则以配准显示的方式结合 显示与第一行为对应的 AR内容和第一目标; 相反的, 当终端发送至服务 器的第二记录事件中不包含第一目标的位置信息时, 终端则以未配准显 示的方式结合显示与第一行为对应的 AR内容和第一目标。

( 3 ) 该用户又来到礼品店 Y和化妆品店 Z , 并分别在这两个店内选 购了礼品和化妆品, 同时店员也将相应的交易信息写入该用户携带的终 端。 同样的, 当该用户携带的终端获取到这两个交易信息时, 该终端分 别将该用户选择礼品和选择化妆品这两个事件记录下来并将这两个事件 上传到服务器。
( 4 )该用户从化妆品店 Z出来后找到离化妆品店 Z最近的收银台进 行缴费, 缴费完成后, 收银台的工作人员将付费凭证和电子发票分别写 入该用户携带的终端。
( 5 ) 当该用户需回到女装品牌店 X、 礼品店 Y及化妆品店 Z出示付 费凭证并领取自己选购的衣服、 礼品及化妆品时, 该用户只记得离收银 台最近的化妆品店 z的位置, 而对女装品牌店 X及礼品店 Y的位置已经 记不清楚了。
( 4 )该用户使用终端中安装的上述获取位置信息的应用拍摄了一张 终端所在位置的全景照片, 终端根据用户拍摄的全景照片确定到化妆品 店 Z 的标识、 收银台的标识以及其他若干个可识别的标识, 并根据这些 标识推断出了该终端所在的位置, 即终端的位置信息, 同时终端发送一 个包括终端的标识和终端的位置信息的第一请求消息至服务器, 当服务 器接收到该第一请求消息后, 服务器根据已经保存的与该终端有关的上 述三个事件和对应的条件概率 (其中, 条件概率为服务器根据收集到的 终端上传的大量数据计算所得) , 得到该用户最有可能的下一行为可能 是:
a、 最近的自动扶梯在哪里?
b、 最近的餐厅在哪里?
c、 返回去过的店铺?
(5)该用户选择了 " c、 返回去过的店铺? " 这个选项对应的行为。 当服务器接收到该用户选择的这个行为后, 服务器根据 "返回去过的店 铺" 这个行为, 从预先保存的 AR内容中筛选出了导航类 AR内容, 该导 航类 AR内容包括该用户去过的店铺附近的显著标志物,从而服务器可根 据记录的与该用户相关的事件、 该购物中心的室内地图及该购物中心内 P0 I的数据, 生成一张从用户所在位置分别前往女装品牌店 X、 礼品店 Y 及化妆品店 Z 的路线图, 并标识出了任何两家店铺之间的显著标志物, 之后, 服务器将这些信息发送至终端, 且终端会将路线图上的显著标志 物、 转弯信息等以 AR的形式显示出来展示给该用户。
( 6 ) 该用户在该应用程序的帮助下找到了女装品牌店 X、 礼品店 Y 及化妆品店 Z , 并分别领取了自己选购的衣月良、 ^品及化妆品。
( 7 )终端将该用户选择返回去过的店铺这一事件记录下来, 并将该 事件发送至服务器, 从而服务器再对该事件进行分类并统计分析。
