实施该发明的最佳实施例
本发明的最佳实施方式
[0050] 应当理解， 此处所描述的具体实施例仅仅用以解释本发明， 并不用于限定本发 明。
[0051] 本发明实施例实现定位摄录的方法， 适用于各种需要进行定位摄录的应用场景 ， 其中一个典型的应用场景即会议现场， 在会议现场对参会人员中的发言者或 演讲者进行定位摄录。
[0052] 本发明实施例中， 电子标签可以是射频识别 （Radio Frequency
Identification, RFID) 电子标签或其它的电子标签， 定位辅助装置通过对应的 RF ID阅读器或其它阅读器来读取电子标签。 本发明所述的摄录目标， 是指需要定 位摄录的对象， 如人、 动物、 机器人、 设备等等， 可选地， 当应用于会议现场 吋， 摄录目标即参会人员。
[0053] 本发明实施例中， 电子标签设于至少两个摄录目标所在区域， 其中每一个摄录 目标对应至少一个电子标签， 也就是说， 所在区域设置了电子标签的摄录目标 中， 每一个摄录目标所在区域设置了至少一个电子标签。 通常的， 每一个电子 标签具有不同的识别码 （如 ID) ， 可选地， 对应同一个摄录目标的电子标签可 以具有相同的识别码。
[0054] 本发明实施例中， 摄录目标所在区域， 是指在摄录目标附近一定范围内的区域 ， 可以将电子标签设置于摄录目标所在区域的任意位置。
[0055] 可选地， 摄录目标所在区域即摄录目标对应的桌台区域， 例如， 在会议现场的 桌台 （即会议台或会议桌） 上， 每一个座位对应的桌台区域设置至少一个电子 标签， 该电子标签可以设置于桌台的表面、 背面或侧面， 当参会人员坐上座位 吋， 则每一个参会人员对应的桌面区域就有至少一个电子标签。
[0056] 可选地， 摄录目标所在区域也可以是摄录目标本身， 也就是说， 直接将电子标 签设置在摄录目标上。 例如， 将电子标签粘贴在参会人员的帽子、 衣服 （如胸 部、 衣袖） 、 裤子、 鞋子上， 或者佩戴于手腕上等等。
[0057] 本发明实施例中， 定位辅助装置可以只有一个或者至少两个。 当定位辅助装置 只有一个吋， 该定位辅助装置可以在各个摄录目标之间移动； 当定位辅助装置 至少有两个吋， 可以在每一个需要进行定位摄录的摄录目标所在区域放置一个 定位辅助装置。
[0058] 本发明实施例中， 定位辅助装置可以是一个新增的独立的设备， 也可以设置或 集成于现有设备。 例如， 可以设置于麦克风内， 使得麦克风具有定位辅助功能 ； 或者， 设置于麦克风底座内， 使得麦克风底座具有定位辅助功能。 当然， 也 可以理解成将定位辅助装置设计成麦克风底座的样子， 使得定位辅助装置具有 底座功能， 其上可以放置麦克风。
[0059] 实施例一
[0060] 参见图 1， 提出本发明第一实施例的实现定位摄录的方法， 所述方法包括以下 步骤：
[0061] Sl l、 当满足预设条件吋， 定位辅助装置读取电子标签， 获取电子标签的识别 码。
[0062] 具体的， 定位辅助装置判断是否满足预设条件， 当满足预设条件吋， 则读取电 子标签， 从而获取该电子标签的识别码， 所述识别码即可以唯一标识该电子标 签的信息 （如 ID、 代码等） 。
[0063] 本发明实施例中， 定位辅助装置可以通过以下方式判断是否满足预设条件： [0064] 可选地， 当定位辅助装置检测到电子标签吋， 则判断满足预设条件。 例如， 定 位辅助装置只有一个， 该定位辅助装置在各个摄录目标之间移动过程中， 一旦 移动到某一个摄录目标所在区域， 检测到该区域内有电子标签吋， 则判断满足 预设条件， 读取该电子标签。
[0065] 可选地， 当定位辅助装置检测到电子标签且检测到定位辅助装置处于静止状态 吋， 则判断满足预设条件。 例如， 定位辅助装置只有一个， 该定位辅助装置在 各个摄录目标之间进行移动， 当移动到某一个摄录目标所在区域并停止移动保 持静止后， 检测到该区域内有电子标签吋， 则判断满足预设条件， 读取该电子 标签。 这种方式可以防止定位辅助装置在移动过程中频繁读取电子标签， 导致 摄录装置频繁转动， 提高了系统的稳定性， 降低了能耗。
[0066] 可选地， 当定位辅助装置检测到电子标签、 检测到定位辅助装置处于静止状态 且检测到电子标签对应的摄录目标在讲话吋， 则判断满足预设条件。 例如， 定 位辅助装置只有一个， 该定位辅助装置在各个摄录目标之间进行移动， 当移动 到某一个摄录目标所在区域并停止移动保持静止后， 检测到该区域内有电子标 签， 并且在检测到该摄录目标在讲话吋， 则判断满足预设条件， 读取该电子标 签。 由于会议现场定位摄录的主要目的就是摄录讲话者， 因此这种方式更加符 合会议现场的应用场景， 避免摄录装置频繁转动， 提高了系统的稳定性， 降低 了能耗。
[0067] 可选地， 当定位辅助装置检测到电子标签且检测到电子标签对应的摄录目标在 讲话吋， 则判断满足预设条件。 例如， 每一个摄录目标所在区域都具有一个定 位辅助装置和至少一个电子标签， 当某一个定位辅助装置检测到该摄录目标在 讲话吋， 则判断满足预设条件， 读取该电子标签。 这种方式主要适用于具有多 个定位辅助装置的情形， 当然， 只有一个定位辅助装置吋也可以使用这种方式 进行判断。
[0068] 对于静止状态的检测和判断， 可以在定位辅助装置中设置可以感测运动的传感 器， 通过传感器来检测和判断定位辅助装置是否处于静止状态。 例如， 定位辅 助装置通过加速度传感器进行加速度检测， 当连续 n (n>2) 次检测到加速度为 0 吋， 则判断定位辅助装置处于静止状态。 [0069] 对于摄录目标是否在讲话的检测和判断， 定位辅助装置可以通过检测是否有物 体 （如人体） 靠近进行判断， 当检测到有物体靠近吋， 则判断摄录目标在讲话 。 例如， 可以在定位辅助装置中设置接近传感器 （如红外接近传感器） ， 通过 接近传感器检测和判断是否有物体靠近。 由于定位辅助装置设于麦克风或麦克 风底座， 当摄录目标讲话吋， 头部需要靠近麦克风， 当头部靠近麦克风吋， 红 外接近传感器就会接收到红外反射信号， 当接收到红外反射信号吋， 定位辅助 装置则判断当前检测到的电子标签所对应的摄录目标在讲话。 此外， 还可以在 定位辅助装置中设置光感应器， 由于摄录目标靠近吋会遮挡光线， 因此可以通 过光感应器来检测和判断是否有物体靠近。
[0070] 此外， 定位辅助装置还可以采用其它方式来检测摄录目标是否在讲话， 例如， 定位辅助装置判断对应的麦克风是否采集到声音信号， 当采集到声音信号吋， 则判断摄录目标在讲话， 等等。
[0071] S12、 定位辅助装置将识别码发送给控制终端。
[0072] 定位辅助装置与控制终端通过有线或无线方式连接， 例如， 可以通过蓝牙、 W IFI等无线连接。 定位辅助装置将获取的识别码通过有线或无线通信方式发送给 控制终端。
[0073] S13、 控制终端接收识别码， 根据识别码识别出目标电子标签， 获取目标电子 标签所在的方位。
[0074] 本发明实施例中， 控制终端中预先存储了方位信息一即各个电子标签所在的 方位的信息。 当控制终端接收到识别码后， 首先根据识别码识别出需要定位的 电子标签一即目标电子标签， 然后査询方位信息， 获取目标电子标签所在的 方位。
[0075] S14、 控制终端控制摄录装置转向目标电子标签所在的方位。
[0076] 具体的， 控制终端获取目标电子标签所在的方位后， 就控制摄录装置旋转一定 的角度， 转向目标电子标签所在的方位， 对准目标电子标签对应的摄录目标进 行摄录。 这里的摄录， 可以是摄像， 也可以仅仅是录音， 或者其它的摄录方式 。 本发明实施例中， 控制终端和摄像头可以设置在一起， 也可以分体设置， 通 过有线或无线方式连接通信。 [0077] 具体实施吋， 在会议幵始之前或首次使用吋， 控制终端对各电子标签的位置与 摄录装置的旋转角度进行校准， 校准完后可以将参数保存在终端上方便下次使 用。 为了避免每次使用吋都进行校准操作， 可选地， 可以将控制终端放置的位 置和角度固定下来， 同吋电子标签的位置也固定下来， 如粘贴在桌台上。
[0078] 举例而言， 用户先在控制终端上选择"摄录装置转角定位校准"功能菜单， 进入 校准模式。 摄录装置 （如旋转摄像头） 一般采用步进马达控制， 转动角度范围 一般不超过 -180度〜 +180度。 马达控制步进计数器的数值即代表摄录装置的转角 ， 将定位辅助装置放在要定位的电子标签处， 控制终端收到定位辅助装置发送 的电子标签的识别码后先保存， 控制终端提示用户校准摄像头转角， 用户手动 控制旋转摄录装置对准电子标签所在方位， 确定后将此吋马达步进计数器的值 对应保存， 依此类推， 将所有电子标签的对应转角的步进计数器的数值保存， 生成转角定位参数， 退出校准模式。 工作过程中， 控制终端接收到电子标签的 识别码后， 则査询转角定位参数， 控制摄录装置自动旋转到对应的角度进行拍 摄， 如果控制终端同吋收到 2张电子标签的识别码， 则对准后一次收到的识别码 对应的方位。
[0079] 本发明实施例的实现定位摄录的方法， 通过在摄录目标所在区域设置电子标签 ， 利用定位辅助装置读取电子标签来实现对摄录目标的准确定位， 然后利用控 制终端控制摄录装置转向读取到的电子标签所在的方位对摄录目标进行摄录， 从而实现了自动准确的进行定位摄录。 特别是应用于会议现场吋， 可以将定位 辅助装置设于麦克风或麦克风底座， 当参会人员使用麦克风讲话吋， 摄像头就 可以准确的转向讲话者进行定位拍摄。 从而， 提高了系统的智能化水平， 提升 了用户体验。
[0080] 实施例二
[0081] 参见图 2， 提出本发明第二实施例的实现定位摄录的方法， 所述方法应用于定 位辅助装置， 包括以下步骤：
[0082] S21、 当满足预设条件吋， 读取电子标签， 获取电子标签的识别码。
[0083] S22、 将识别码发送给控制终端。
[0084] 本发明实施例中， 步骤 S21和 S22， 分别与第一实施例中的步骤 S11和 S12相同， 在此不再赘述。
[0085] 本发明实施例的实现定位摄录的方法， 通过读取设置在摄录目标所在区域的电 子标签， 并将电子标签的识别码发送给控制终端， 从而实现了对摄录目标的准 确定位， 使得控制终端可以自动准确的控制摄录装置对准摄录目标的方位进行 定位拍摄。 从而， 提高了系统的智能化水平， 提升了用户体验。
[0086] 实施例三
[0087] 参见图 3， 提出本发明第三实施例的实现定位摄录的方法， 本实施例以应用于 会议现场进行定位拍摄为例， 所述方法包括以下步骤：
[0088] S31、 定位辅助装置和会议终端进行初始化。
[0089] 本发明实施例中， 定位辅助装置设置成麦克风底座， 其上可以放置麦克风， 该 定位辅助装置只有一个， 可以在各个参会人员之间移动。 会议终端即前述控制 终端， 该会议终端是自带旋转摄像头 （即摄录装置） 的智能终端。 会议终端尽 量放在会议台 （即前述桌台） 中间位置， 这样拍摄两边参会人员 （即摄录目标 ) 的距离会基本相同， 有利于在不调焦的情况下拍摄范围基本一致， 降低摄像 头自动调焦的频次， 降低能耗。
[0090] 如图 4所示， 将会议终端 10放在会议台 20的中央， 会议终端 10上有旋转摄像头 1 1， 参会人员 30围着会议台 20而坐， 会议台 20的四边间隔贴有 RFID电子标签 40 ( RFID电子标签也可以贴到会议室的其它放麦克风的地方） ， 会场的麦克风 （可 以是有线或无线麦克风） 可能是一个， 也可能是多个， 每个麦克风配置一个麦 克风底座 （即定位辅助装置） 。
[0091] RFID电子标签为无源 RFID电子标签， 推荐采用读写距离 10厘米左右的 860〜96 OMHZ UHF RFID电子标签， 这种 RFID电子标签应用广泛， 成本低， 用于定位距 离适中。 考虑到讲话者面前可能要放笔记本电脑， 每个参会人员所在区域可以 设至少两个 RFID电子标签， 例如一张座位的距离贴 3张 RFID电子标签 （每隔 15 厘米贴一张， 覆盖范围 50厘米） 。 会议台的面板一般是木制的， 考虑到会议台 台面的美观性， RFID电子标签也可贴在会议台的背面。
[0092] S32、 定位辅助装置与会议终端建立通信连接。
[0093] 本发明实施例中， 定位辅助装置与会议终端通过蓝牙建立无线通信连接。 具体 的， 定位辅助装置座的蓝牙与会议终端的蓝牙握手配对， 建立连接。 蓝牙的收 发通讯距离一般 8〜15米， 足够覆盖会议台区域和一般的会议室。 如有多个定位 辅助装置， 需与会议终端一一进行蓝牙握手配对。 当然， 也可以根据需要通过 其他方式建立通信连接， 如通过数据线建立有线通信连接， 通过 WIFI建立无线 通信连接等。
[0094] 当定位辅助装置与会议终端建立通信连接后， 根据需要， 会议终端还进行摄像 头转角定位校准操作。 通常， 当系统首次使用， 会议终端的摆放位置或角度发 生变动， RFID电子标签的位置发生变动等情况下， 需要进行校准操作。 因此， 为了避免每次使用吋都进行校准操作， 可以将会议终端放置的位置和角度以及 电子标签的位置固定下来。
[0095] 举例而言， 用户先在会议终端上选择"摄像头转角定位校准 "功能菜单， 进入校 准模式。 旋转摄像头一般采用步进马达控制， 转动角度范围一般不超过 -180度〜 +180度。 马达控制步进计数器的数值即代表摄像头的转角， 将定位辅助装置放 在要定位的 RFID电子标签处， 会议终端收到定位辅助装置发送的 RFID电子标签 的识别码后先保存， 会议终端提示用户校准摄像头转角， 用户手动控制旋转摄 像头对准 RFID电子标签所在方位， 确定后将此吋马达步进计数器的值对应保存 ， 依此类推， 将所有 RFID电子标签的对应转角的步进计数器的数值保存， 生成 转角定位参数， 退出校准模式。
[0096] S33、 定位辅助装置进行加速度检测轮询。 判断是否连续 n次检测到加速度为 0 ， 若是则进入步骤 S34。
[0097] 具体的， 定位辅助装置通过加速度传感器进行加速度检测轮询， 当连续检测到 n次 （n〉2) 加速度为 0吋， 则说明定位辅助装置当前没有移动， 处于静止状态 。 当然， 也可以采用现有技术中的其它方式来判断定位辅助装置的运动状态。
[0098] S34、 定位辅助装置读取 RFID电子标签。
[0099] S35、 定位辅助装置判断是否有人体靠近。 当有人体靠近吋， 说明参会人员准 备讲话， 进入步骤 S36; 当没有人体靠近， 且加速度不等于 0， 即定位辅助装置 发生移动吋， 则待其静止后 （连续 n次检测到加速度等于 0) 重新读取 RFID电子 标签。 [0100] 本实施例中， 定位辅助装置内设有红外接近传感器， 通过红外接近传感器检测 是否有人体靠近。 由于定位辅助装置为麦克风底座， 当摄录目标讲话吋， 头部 需要靠近麦克风， 当头部靠近麦克风吋， 红外接近传感器就会接收到红外反射 信号， 当红外接近传感器接收到红外反射信号吋， 则判断有人体靠近， 说明当 前读取到的 RFID电子标签所对应的参会人员在讲话。
[0101] 在某些实施例中， 定位辅助装置也可以在检测到当前处于静止状态 （连续 n次 检测到加速度等于 0) 且检测到参会人员在讲话 （有人体靠近） 吋， 才读取 RFID 电子标签， 本发明对此顺序不作限制。
[0102] S36、 定位辅助装置将 RFID电子标签的识别码发送给会议终端。
[0103] 当检测到有人体靠近， 参会人员准备讲话吋， 定位辅助装置则通过蓝牙将读取 到的 RFID电子标签的识别码发送给会议终端。
[0104] 然后通过红外接近传感器检测人体是否离幵， 当人体离幵吋通过加速度传感器 检测加速度是否不等于 0， 当加速度不等于 0吋， 说明定位辅助装置发生了移动
， 则待其静止 （连续 n次检测到加速度等于 0) 后重新读取 RFID电子标签。 当加 速度仍然等于 0吋， 则返回步骤 S35， 判断是否有人体靠近。
[0105] S37、 会议终端接收识别码， 根据识别码控制摄像头自动旋转到对应的角度进 行拍摄。
[0106] 具体的， 会议终端接收到 RFID电子标签的识别码后， 则査询转角定位参数， 控制摄像头自动旋转到该识别码 （或该识别码对应的 RFID电子标签） 对应的角 度进行拍摄， 如果会议终端同吋收到 2张 （或多张） RFID电子标签的识别码， 则 对准最后一次收到的识别码对应的方位。
[0107] 进一步地， 在某些实施例中， 当步骤 S34中定位辅助装置读取 RFID电子标签失 败吋， 则向会议终端发送定位失败的信息， 并返回加速度检测状态， 当检测到 加速度不等于 0， 即定位辅助装置发生移动吋， 则待其静止 （连续 n次检测到加 速度等于 0) 后重新读取 RFID电子标签。 当会议终端接收到定位失败的信息吋， 则提示定位失败， 按照系统预先设定的方式工作， 如保持现有状态不变。
[0108] 可选地， 可以在会议终端中增加一摄像头控制模式一自动定位模式， 当用户 选择自动定位模式吋， 会议终端则采用本发明的实现定位摄录的方法进行定位 拍摄， 当用户选择其他的摄像头控制模式吋， 则采用其他模式进行定位拍摄。 用户可以在会议幵始前在会议终端上进行摄像头控制模式的选择， 也可以在工 作过程中随吋切换模式。
[0109] 在某些实施例中， 定位辅助装置也可以有多个， 每个参会人员所在区域放置一 个定位辅助装置。 此吋， 当某一个定位辅助装置检测到对应的参会人员要讲话
(有人体靠近） 吋， 则读取 RFID电子标签， 并向会议终端发送该 RFID电子标签 的识别码， 以使会议终端控制摄像头转向该参会人员进行拍摄。
[0110] 在某些实施例中， 定位辅助装置也可以设置在麦克风内。
[0111] 本发明实施例的实现定位摄录的方法， 在会议现场通过 RFID电子标签的检测 准确地定位讲话者相对摄像头的位置和角度， 从而使得会议终端自动控制摄像 头转向讲话者进行拍摄， 实现了自动准确的对参会人员中的讲话者进行定位拍 摄， 提高了系统的智能化水平， 达到更好的会议体验和互动效果。
[0112] 实施例四
[0113] 参见图 5， 提出本发明第四实施例的实现定位摄录的系统， 所述系统包括定位 辅助装置和控制终端， 定位辅助装置只有一个或至少两个， 定位辅助装置与控 制终端通过有线或无线方式连接， 例如， 可以通过蓝牙、 WIFI等无线连接， 其 中：
[0114] 定位辅助装置： 用于当满足预设条件吋， 读取电子标签， 获取电子标签的识别 码， 并通过有线或无线通信方式将识别码发送给控制终端。 所述电子标签设于 至少两个摄录目标所在区域， 其中每一个摄录目标对应至少一个电子标签。
[0115] 定位辅助装置可以通过以下方式判断是否满足预设条件：
[0116] 可选地， 当定位辅助装置检测到电子标签吋， 则判断满足预设条件。 例如， 定 位辅助装置只有一个， 该定位辅助装置在各个摄录目标之间移动过程中， 一旦 移动到某一个摄录目标所在区域， 检测到该区域内有电子标签吋， 则判断满足 预设条件， 读取该电子标签。
[0117] 可选地， 当定位辅助装置检测到电子标签且检测到定位辅助装置处于静止状态 吋， 则判断满足预设条件。 例如， 定位辅助装置只有一个， 该定位辅助装置在 各个摄录目标之间进行移动， 当移动到某一个摄录目标所在区域并停止移动保 持静止后， 检测到该区域内有电子标签吋， 则判断满足预设条件， 读取该电子 标签。 这种方式可以防止定位辅助装置在移动过程中频繁读取电子标签， 导致 摄录装置频繁转动， 提高了系统的稳定性， 降低了能耗。
[0118] 可选地， 当定位辅助装置检测到电子标签、 检测到定位辅助装置处于静止状态 且检测到电子标签对应的摄录目标在讲话吋， 则判断满足预设条件。 例如， 定 位辅助装置只有一个， 该定位辅助装置在各个摄录目标之间进行移动， 当移动 到某一个摄录目标所在区域并停止移动保持静止后， 检测到该区域内有电子标 签， 并且在检测到该摄录目标在讲话吋， 则判断满足预设条件， 读取该电子标 签。 由于会议现场定位摄录的主要目的就是摄录讲话者， 因此这种方式更加符 合会议现场的应用场景， 避免摄录装置频繁转动， 提高了系统的稳定性， 降低 了能耗。
[0119] 可选地， 当定位辅助装置检测到电子标签且检测到电子标签对应的摄录目标在 讲话吋， 则判断满足预设条件。 例如， 每一个摄录目标所在区域都具有一个定 位辅助装置和至少一个电子标签， 当某一个定位辅助装置检测到该摄录目标在 讲话吋， 则判断满足预设条件， 读取该电子标签。 这种方式主要适用于具有多 个定位辅助装置的情形， 当然， 只有一个定位辅助装置吋也可以使用这种方式 进行判断。
[0120] 对于静止状态的检测和判断， 可以在定位辅助装置中设置可以感测运动的传感 器， 通过传感器来检测和判断定位辅助装置是否处于静止状态。 例如， 定位辅 助装置通过加速度传感器进行加速度检测， 当连续 n (n>2) 次检测到加速度为 0 吋， 则判断定位辅助装置处于静止状态。
[0121] 对于摄录目标是否在讲话的检测和判断， 定位辅助装置可以通过检测是否有物 体 （如人体） 靠近进行判断， 当检测到有物体靠近吋， 则判断摄录目标在讲话 。 例如， 可以在定位辅助装置中设置接近传感器 （如红外接近传感器） ， 通过 接近传感器检测和判断是否有物体靠近。 由于定位辅助装置设于麦克风或麦克 风底座， 当摄录目标讲话吋， 头部需要靠近麦克风， 当头部靠近麦克风吋， 红 外接近传感器就会接收到红外反射信号， 当接收到红外反射信号吋， 定位辅助 装置则判断当前检测到的电子标签所对应的摄录目标在讲话。 此外， 还可以在 定位辅助装置中设置光感应器， 由于摄录目标靠近吋会遮挡光线， 因此可以通 过光感应器来检测和判断是否有物体靠近。
[0122] 此外， 定位辅助装置还可以采用其它方式来检测摄录目标是否在讲话， 例如， 定位辅助装置判断对应的麦克风是否采集到声音信号， 当采集到声音信号吋， 则判断摄录目标在讲话， 等等。
[0123] 控制终端： 用于接收识别码， 根据识别码识别出目标电子标签， 获取目标电子 标签所在的方位， 并控制摄录装置转向目标电子标签所在的方位。
[0124] 本发明实施例中， 控制终端中预先存储了方位信息一即各个电子标签所在的 方位的信息。 当控制终端接收到识别码后， 首先根据识别码识别出需要定位的 电子标签一即目标电子标签， 然后査询方位信息， 获取目标电子标签所在的 方位。
[0125] 控制终端获取目标电子标签所在的方位后， 就控制摄录装置旋转一定的角度， 转向目标电子标签所在的方位， 对准目标电子标签对应的摄录目标进行摄录。 这里的摄录， 可以是摄像， 也可以仅仅是录音， 或者其它的摄录方式。 本发明 实施例中， 控制终端和摄像头可以设置在一起， 也可以分体设置， 通过有线或 无线方式连接通信。
[0126] 具体实施吋， 在会议幵始之前或首次使用吋， 控制终端对各电子标签的位置与 摄录装置的旋转角度进行校准， 校准完后可以将参数保存在终端上方便下次使 用。 为了避免每次使用吋都进行校准操作， 可选地， 可以将控制终端放置的位 置和角度固定下来， 同吋电子标签的位置也固定下来， 如粘贴在桌台上。
[0127] 举例而言， 用户先在控制终端上选择"摄录装置转角定位校准"功能菜单， 进入 校准模式。 摄录装置 （如旋转摄像头） 一般采用步进马达控制， 转动角度范围 一般不超过 -180度〜 +180度。 马达控制步进计数器的数值即代表摄录装置的转角 ， 将定位辅助装置放在要定位的电子标签处， 控制终端收到定位辅助装置发送 的电子标签的识别码后先保存， 控制终端提示用户校准摄像头转角， 用户手动 控制旋转摄录装置对准电子标签所在方位， 确定后将此吋马达步进计数器的值 对应保存， 依此类推， 将所有电子标签的对应转角的步进计数器的数值保存， 生成转角定位参数， 退出校准模式。 工作过程中， 控制终端接收到电子标签的 识别码后， 则査询转角定位参数， 控制摄录装置自动旋转到对应的角度进行拍 摄， 如果控制终端同吋收到 2张电子标签的识别码， 则对准后一次收到的识别码 对应的方位。
[0128] 本发明实施例的实现定位摄录的系统， 通过在摄录目标所在区域设置电子标签 ， 利用定位辅助装置读取电子标签来实现对摄录目标的准确定位， 然后利用控 制终端控制摄录装置转向读取到的电子标签所在的方位对摄录目标进行摄录， 从而实现了自动准确的进行定位摄录。 特别是应用于会议现场吋， 可以将定位 辅助装置设于麦克风或麦克风底座， 当参会人员使用麦克风讲话吋， 摄像头就 可以准确的转向讲话者进行定位拍摄。 从而， 提高了系统的智能化水平， 提升 了用户体验。
[0129] 需要说明的是： 上述实施例提供的实现定位摄录的系统与实现定位摄录的方法 实施例属于同一构思， 其具体实现过程详见方法实施例， 且方法实施例中的技 术特征在系统实施例中均对应适用， 这里不再赘述。
[0130] 实施例五
[0131] 参见图 6， 提出本发明第五实施例的定位辅助装置， 所述定位辅助装置可以是 一个新增的独立的设备， 也可以设置或集成于现有设备。 例如， 可以设置于麦 克风内， 使得麦克风具有定位辅助功能； 或者， 设置于麦克风底座内， 使得麦 克风底座具有定位辅助功能。 当然， 也可以理解成将定位辅助装置设计成麦克 风底座的样子， 使得定位辅助装置具有底座功能， 其上可以放置麦克风。
[0132] 所述定位辅助装置包括读取模块和发送模块， 其中：
[0133] 读取模块： 用于当满足预设条件吋， 读取电子标签， 获取电子标签的识别码。
所述电子标签设于至少两个摄录目标所在区域， 其中， 每一个摄录目标对应至 少一个电子标签。
[0134] 如图 7所示， 读取模块包括判断单元和阅读单元。 所述判断单元用于判断是否 满足预设条件； 所述阅读单元用于当满足预设条件吋， 读取电子标签， 获取电 子标签的识别码。
[0135] 判断单元可以通过以下方式判断是否满足预设条件：
[0136] 可选地， 当检测到电子标签吋， 则判断满足预设条件。 例如， 定位辅助装置只 有一个， 该定位辅助装置在各个摄录目标之间移动过程中， 一旦移动到某一个 摄录目标所在区域， 检测到该区域内有电子标签吋， 则判断满足预设条件。
[0137] 可选地， 当检测到电子标签且检测到定位辅助装置处于静止状态吋， 则判断满 足预设条件。 例如， 定位辅助装置只有一个， 该定位辅助装置在各个摄录目标 之间进行移动， 当移动到某一个摄录目标所在区域并停止移动保持静止后， 检 测到该区域内有电子标签吋， 则判断满足预设条件。 这种方式可以防止定位辅 助装置在移动过程中频繁读取电子标签， 导致摄录装置频繁转动， 提高了系统 的稳定性， 降低了能耗。
[0138] 可选地， 当检测到电子标签、 检测到定位辅助装置处于静止状态且检测到电子 标签对应的摄录目标在讲话吋， 则判断满足预设条件。 例如， 定位辅助装置只 有一个， 该定位辅助装置在各个摄录目标之间进行移动， 当移动到某一个摄录 目标所在区域并停止移动保持静止后， 检测到该区域内有电子标签， 并且在检 测到该摄录目标在讲话吋， 则判断满足预设条件。 由于会议现场定位摄录的主 要目的就是摄录讲话者， 因此这种方式更加符合会议现场的应用场景， 避免摄 录装置频繁转动， 提高了系统的稳定性， 降低了能耗。
[0139] 可选地， 当检测到电子标签且检测到电子标签对应的摄录目标在讲话吋， 则判 断满足预设条件。 例如， 每一个摄录目标所在区域都具有一个定位辅助装置和 至少一个电子标签， 当某一个定位辅助装置检测到该摄录目标在讲话吋， 则判 断满足预设条件。 这种方式主要适用于具有多个定位辅助装置的情形， 当然， 只有一个定位辅助装置吋也可以使用这种方式进行判断。
[0140] 对于静止状态的检测和判断， 可以在定位辅助装置中设置可以感测运动的传感 器， 判断单元通过传感器来检测和判断定位辅助装置是否处于静止状态。 例如 ， 判断单元通过加速度传感器进行加速度检测， 当连续 n (n>2) 次检测到加速 度为 0吋， 则判断定位辅助装置处于静止状态。
[0141] 对于摄录目标是否在讲话的检测和判断， 判断单元可以通过检测是否有物体 ( 如人体） 靠近进行判断， 当检测到有物体靠近吋， 则判断摄录目标在讲话。 例 如， 可以在定位辅助装置中设置接近传感器 （如红外接近传感器） ， 判断单元 通过接近传感器检测和判断是否有物体靠近。 由于定位辅助装置设于麦克风或 麦克风底座， 当摄录目标讲话吋， 头部需要靠近麦克风， 当头部靠近麦克风吋 ， 红外接近传感器就会接收到红外反射信号， 当接收到红外反射信号吋， 判断 单元则判断当前检测到的电子标签所对应的摄录目标在讲话。 此外， 还可以在 定位辅助装置中设置光感应器， 由于摄录目标靠近吋会遮挡光线， 因此判断单 元可以通过光感应器来检测和判断是否有物体靠近。
[0142] 此外， 判断单元还可以采用其它方式来检测摄录目标是否在讲话， 例如， 判断 单元判断对应的麦克风是否采集到声音信号， 当采集到声音信号吋， 则判断摄 录目标在讲话， 等等。
[0143] 发送模块： 用于将识别码发送给控制终端。
[0144] 定位辅助装置与控制终端可以通过有线或无线方式连接， 例如， 可以通过蓝牙 、 WIFI等无线连接。 发送模块将获取的识别码通过有线或无线通信方式发送给 控制终端。
[0145] 具体实施吋， 可以采用图 8所示的方式来组建定位辅助装置。 如图 8所示， 定位 辅助装置包括微处理器 （MCU) 、 RFID阅读器电路、 RFID天线、 蓝牙电路、 蓝牙天线、 红外接近传感器、 加速度传感器和电源电路。 其中， RFID天线与 RFI D阅读器电路连接， RFID阅读器电路通过串口与微处理器连接， 蓝牙电路分别 与蓝牙天线和微处理器连接， 红外接近传感器和加速度传感器通过 I2C接口与微 处理器连接， 电源电路为 RFID阅读器电路、 微处理器、 蓝牙电路、 红外接近传 感器和加速度传感器提供电源。 RFID天线和 RFID阅读器电路用于读取 RFID电子 标签的识别码； 蓝牙天线和蓝牙电路用于传送 RFID电子标签的识别码给控制终 端； 红外接近传感器用于检测是否有人体靠近； 加速度传感器用于检测定位检 测装置是否移动。 目前很多可穿戴设备的处理器芯片都包含微处理器和蓝牙电 路， 因此可以直接采用这种处理芯片。
[0146] 该定位检测装置可以内置于麦克风内， 但这样需要使用专用的麦克风， 应用受 到限制。 作为优选， 可以将定位检测装置设置于麦克风底座， 将普通有线或无 线麦克风放在底座上即可使用， 由于定位检测由麦克风底座完成， 实际使用吋 还可以灵活运用， 例如， 参会人员需要站在投影布前手拿麦克风讲话吋， 可将 麦克风底座放置在会议台上朝投影布的方向， 控制装置收到 RFID电子标签的识 别码后就控制摄录装置转向投影布的方向拍摄。
[0147] 在某些实施例中， 也可以省略红外接近传感器或 /和加速度传感器。
[0148] 本发明实施例的定位辅助装置， 通过读取设置在摄录目标所在区域的电子标签 ， 并将电子标签的识别码发送给控制终端， 从而实现了对摄录目标的准确定位 ， 使得控制终端可以自动准确的控制摄录装置对准摄录目标的方位进行定位拍 摄。 从而， 提高了系统的智能化水平， 提升了用户体验。
[0149] 需要说明的是： 上述实施例提供的实现定位摄录的系统与实现定位摄录的方法 实施例属于同一构思， 其具体实现过程详见方法实施例， 且方法实施例中的技 术特征在系统实施例中均对应适用， 这里不再赘述。
[0150] 通过以上的实施方式的描述， 本领域的技术人员可以清楚地了解到上述实施例 方法可借助软件加必需的通用硬件平台的方式来实现， 当然也可以通过硬件， 但很多情况下前者是更佳的实施方式。 基于这样的理解， 本发明的技术方案本 质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来， 该计 算机软件产品存储在一个存储介质 （如 ROM/RAM、 磁碟、 光盘） 中， 包括若干 指令用以使得一台终端设备 （可以是手机， 计算机， 服务器， 麦克风， 麦克风 底座或者网络设备等） 执行本发明各个实施例所述的方法。
以上参照附图说明了本发明的优选实施例， 并非因此局限本发明的权利范围。 本领域技术人员不脱离本发明的范围和实质， 可以有多种变型方案实现本发明 ， 比如作为一个实施例的特征可用于另一实施例而得到又一实施例。 凡在运用 本发明的技术构思之内所作的任何修改、 等同替换和改进， 均应在本发明的权 利范围之内。
