[0041] 还需要说明的是, 本实施例中的左、 右、 上、 下等方位用语, 仅是互为相对概 念或是以产品的正常使用状态为参考的, 而不应该认为是具有限制性的。
[0042] 如图 1和图 2所示, 本实施例的疲劳分心智能检测装置包括壳体 10、 固定安装板 20、 控制电路板 30、 信号传输端子 40、 第一滤光镜片 50、 补光灯组件 60以及检 测镜头组件 70, 壳体 10具有安装空腔, 固定安装板 20安装在壳体 10的安装空腔 内, 控制电路板 30连接在固定安装板 20上, 信号传输端子 40与控制电路板 30电 连接, 且信号传输端子 40的传输头由壳体 10的第一端穿出, 第一滤光镜片 50安 装在壳体 10的第二端上, 补光灯组件 60连接在固定安装板 20上, 且补光灯组件 6 0的出射光方向朝向第一滤光镜片 50并由该第一滤光镜片 50过滤出射, 检测镜头 组件 70连接在固定安装板 20上, 检测镜头组件 70与控制电路板 30电连接, 检测 镜头组件 70的镜头穿过补光灯组件 60后朝向第一滤光镜片 50以进行摄像检测。
[0043] 应用该疲劳分心智能检测装置对待测人员进行摄像操作, 从而采集待测人员的 精神状态以及待测人员的分心行为过程的图像信息, 并加以智能分析判断, 以 便智能分析判断出待测人员的精神面貌是否出现疲劳状态或者判断待测人员的 行为状态是否处于分心行为过程。 然后, 根据智能分析所判断出的待测人员的 精神状态或者分心行为过程而采取相应措施, 从而避免待测人员在疲劳的精神 状态或者分心行为过程的情况下工作, 保证了待测人员的精神、 人身安全, 并 且有效地杜绝了安全事故的发生, 保护了财产安全避免损失。
[0044] 本申请均以汽车驾驶员为待测人员进行举例说明。
[0045] 在利用检测镜头组件 70对汽车驾驶员进行摄像操作的过程中, 在白天光线充足 吋候, 检测镜头组件 70的镜头能够清晰地拍摄汽车驾驶员的精神状态或者分心 行为过程的图像信息, 但是在夜晚光线昏暗的条件下, 检测镜头组件 70就无法 清晰地拍摄汽车驾驶员的精神状态或者分心行为过程的图像信息, 此吋就需要 对检测镜头组件 70的镜头进行补光以达到拍摄获得清晰的汽车驾驶员的图像信 息。 然而, 使用传统的 850nm红外补偿光灯进行光学补偿, 该波段红外光可视性 比较强, 能够干扰人的正常视觉, 且因人有在强光下戴有色眼镜进行眼睛防护 的需求, 这就需要有足够强的 850nm红外补偿光才能穿透有色眼镜片, 当 850nm 红外补偿光光强足够吋便能够对人眼产生刺激作用, 同吋, 长吋间点亮 850nm红 外补偿光灯来达到穿透有色眼镜镜片的强度方式会产生大量热量, 这使得设备 需要具有足够的散热能力, 使得设备的兼容性差以及使用环境要求高。 因此, 本实施例的补光灯组件 60所传送出的光线波段处于 920nm至 960nm之间, 在保证 光线穿透能力的基础上, 有效降低因补光需求产生的热量。 并且在本实施例中 , 第一滤光镜片 50能够将 940±10nm光谱的光线通过以使该光线穿过该第一滤光 镜片 50, 并且第一滤光镜片 50将 940±10nm光谱以外的光线过滤掉。 这样, 补光 灯组件 60所传送出的光线经第一滤光镜片 50过滤后得到的光线波段为 940±10nm 光线, 优选为 940nm光线带宽 30±5nm, 1 85<¾@带通区, 1¾& <3<¾@截止区, 这对汽车驾驶员的刺激程度明显减弱, 使得汽车驾驶员眼睛的舒适度变得良好
[0046] 如图 1所示, 壳体 10包括壳身本体 11和后挡板 12, 后挡板 12设置在壳身本体 11 的第一端上, 第一滤光镜片 50设置在壳身本体 11的第二端上, 后挡板 12上设置 有多个延伸进壳身本体 11的安装空腔内的连接柱 121, 固定安装板 20通过螺钉 81 连接在连接柱 121上, 信号传输端子 40的传输头从后挡板 12穿出。 在安装完成固 定安装板 20之后, 便能够将其余零部件进行安装连接, 使得所有组成的零部件 均位于安装空腔内。 补光灯组件 60包括补光灯板 61、 多个补光灯和多个聚光增 透镜 62, 检测镜头组件 70的镜头穿设在补光灯板 61上使得补光灯板 61能够被连 接固定住, 多个补光灯围绕检测镜头组件 70的镜头均匀分布在补光灯板 61上, 多个补光灯均与控制电路板 30电连接, 利用多个聚光增透镜 62—一对应第罩住 多个补光灯, 使得补光灯所发出的光线经聚光增透镜 62汇聚之后传送向第一滤 光镜片 50以便对待测人员进行补光传送。
[0047] 在本实施例中, 检测镜头组件 70包括镜头固定结构件 71、 摄像镜头 72、 镜头传 感器板 73、 第二滤光镜片 74和镜头焦距配合圈 75, 镜头固定结构件 71连接在固 定安装板 20上, 摄像镜头 72安装在镜头固定结构件 71上, 且摄像镜头 72穿过补 光灯组件 60后朝向第一滤光镜片 50以进行摄像检测, 镜头传感器板 73设置在镜 头固定结构件 71与控制电路板 30之间, 镜头传感器板 73与控制电路板 30电连接 , 第二滤光镜片 74设置在摄像镜头 72与镜头固定结构件 71之间。 镜头焦距配合 圈 75则用于调节摄像镜头 72的摄像焦距, 通过将镜头焦距配合圈 75设置在摄像 镜头 72上, 在镜头焦距配合圈 75进行装配配合的过程中, 首先利用镜头焦距配 合圈 75对摄像镜头 72相对于待测人员的焦距调节好 (在本实施例中, 依据被摄 像对象与镜头之间的距离选择不同焦距的摄像镜头 72, 例如摄像镜头 72的焦距 为 6mm、 8mm、 12mm等) , 然后在两者之间通过打胶固定的方式, 使得摄像镜 头 72相对于待测人员的焦距固定, 再将该疲劳分心智能检测装置固定安装在驾 驶位的相应固定位置, 从而专门针对驾驶员的精神状态是否处于疲劳或者驾驶 员的行为举止是否处于分心行为过程进行摄像判别。 在本实施例中, 各个补光 灯均采用 LED补光灯发射补充光线, 然后利用聚光增透镜 62将 LED补光灯发出的 光线进行汇聚后射出, 并通过第一滤光镜片 50对 LED补光灯所发出光线中的 940η m光进行过滤后射向汽车驾驶员从而实现对摄像环境补光。
[0048] 在本申请中, 使用聚光增透镜 62对补光灯所发出的光进行聚光后发射, 能够将 光线聚集在起来, 形成更高的光强, 从而增加光照的射程, 并且增加补光亮度 , 使得摄像环境的补光效果更好。 在实际应用中, 补光灯的数量设置按照实际 使用的需求进行设计, 在此并不唯一限定。
[0049] 本实施例中优选为两个补光灯, 两个补光灯相对于智能检测检测镜头组件 70的 摄像镜头 72对称地设置在补光灯板 61的两端上。 同样, 本实施例的聚光增透镜 6 2也是两个, 分别罩住相应的补光灯, 从而对补光灯所发出的补光光线进行汇聚 后传送向第一滤光镜片 50, 使得补光灯传送向第一滤光镜片 50的光强增强。
[0050] 如图 1所示, 在对该疲劳分心智能检测装置进行装配的过程中, 先将固定安装 板 20连接在后挡板 12上进行固定之后, 然后利用第二连接螺钉 82将过渡连接杆 8 3的一端部连接在固定安装板 20上, 接着将控制电路板 30上的对应通孔穿过过渡 连接杆 83的另一端部后在利用过渡螺母 85对控制电路板 30进行压紧, 然后将镜 头传感器板 73放置在过渡螺母 85上, 再利用第三连接螺钉 84与过渡螺母 85配合 对镜头传感器板 73进行连接固定。 在对镜头固定结构件 71进行安装连接的过程 中, 通过将镜头固定结构件 71与镜头传感器板 73相接, 然后利用第四连接螺钉 8 6进行拧紧固定。 随后将第二滤光镜片 74、 摄像镜头 72、 镜头焦距配合圈 75和补 光灯组件 60依次进行安装、 调节即可完成。
[0051] 另外, 由于人的隐私心理原因, 人在被外露的摄像头监控拍摄的过程中是容易 产生抗拒心理的。 而本申请的疲劳分心智能检测装置的摄像镜头 72被隐藏安装 在壳体 10内, 使得汽车驾驶员并没有直观看见摄像镜头 72正在对自己进行拍摄 采集图像信息, 因而能够较好地调整汽车驾驶员的心理接受程度。
[0052] 摄像镜头 72及过滤 940nm光的第一滤光镜片 50和过滤 940nm光的第二滤光镜片 7 4构成的双层 940nm光学过滤结构, 使得疲劳分心智能检测装置不受自然光照或 人造强光照的影响, 达到防止其他波长的光干扰基于机器视觉的疲劳分心智能 检测设备录像品质。
[0053] 根据本申请的另一方面, 提供了一种疲劳分心智能检测分析系统。 该疲劳分心 智能检测分析系统包括智能分析处理器 (未图示) 和智能检测装置, 其中, 智 能检测装置为前述的疲劳分心智能检测装置, 智能分析处理器的数据输入端口 与疲劳分心智能检测装置的信号传输端子 40的传输头电连接。
[0054] 在利用本申请的疲劳分心智能检测装置对汽车驾驶员进行摄像操作采集图像信 息之后, 疲劳分心智能检测装置的控制电路板 30对图像信号进行转换成为电信 号之后再通过信号传输端子 40将所采集的图像信息传送至智能分析处理器进行 智能分析处理, 从而智能分析判断汽车驾驶员的精神状态与行为是否处于疲劳 分心状态, 然后进行针对性地采取预防措施。
[0055] 在本实施例中, 疲劳分心智能检测装置的补光灯板 61上安装有报警指示灯 (未 图示) , 该报警指示灯朝向第一滤光镜片 50, 并且报警指示灯与控制电路板 30 电连接, 在第一滤光镜片 50的对应报警指示灯的位置上设置了镂空出光区域。 当疲劳分心智能检测装置智能检测到汽车驾驶员存在疲劳的精神状态或者汽车 驾驶员正处于分心行为过程吋候, 智能分析处理器将向控制电路板 30发出使报 警指示灯闪烁的报警控制指令。 此吋, 闪烁的报警指示灯所发出的灯光从镂空 出光区域传送出去, 汽车驾驶员在看到报警指示灯发出的闪烁灯光之后, 便会 产生警觉。
[0056] 在控制电路板 30上也设置有能够发出语音报警提示的声音提醒喇叭, 在疲劳分 心智能检测装置智能检测到汽车驾驶员存在疲劳的精神状态或者汽车驾驶员正 处于分心行为过程吋候, 智能分析处理器将向控制电路板 30也会发出指令使得 声音提醒喇叭响起, 从而提醒汽车驾驶员注意。 并且, 智能分析处理器向控制 电路板 30发出警报指令之后, 控制电路板 30是同步启动声音提醒喇叭和报警指 示灯的, 这样, 汽车驾驶员会在光学报警提示以及语音报警提示的双重提示下 获得警示提示。
[0057] 在疲劳分心智能检测装置对汽车驾驶员进行补光摄像操作的过程中, 由于镂空 出光区域的设计, 第一滤光镜片 50外部的光也会有少量光线从该镂空出光区域 传送进入摄像镜头 72中, 然后光线经摄像镜头 72传送至第二滤光镜片 74再次进 行过滤 (此处将第二滤光镜片 74进行密封, 使得光线只能通过第二滤光镜片 74 进行过滤后才能继续向后传送) , 从而将 940nm红外光之外的光线过滤掉而仅仅 剩下 940nm红外光传送至镜头传感器板 73上并最终成像。
[0058] 根据本申请的又一方面, 提供了一种疲劳分心智能检测处理方法。 如图 3所示 , 该疲劳分心智能检测处理方法应用前述的疲劳分心智能检测分析系统进行智 能检测分析操作, 智能检测分析操作包括以下步骤:
[0059] 步骤 S10: 在疲劳分心智能检测分析系统的智能分析处理器中预先保存体现人 员疲劳分心的基础数据;
[0060] 步骤 S20: 通过疲劳分心智能检测分系统的智能检测装置针对待检测人员进行 摄像操作, 将所得到的待检测人员的图像信息传送至智能分析处理器;
[0061] 步骤 S30: 调取智能分析处理器中预先保存的基础数据, 将所得到的待检测人 员的图像信息与基础数据运行智能算法进行智能分析, 以智能分析判断待检测 人员是否处于疲劳分心状态。
[0062] 应用大数据原理, 将现实生活中人们经常表现的精神疲劳状态、 分心行为的表 现行为作为基础数据存储在智能分析处理器中, 因而智能分析处理器成为进行 智能分析数据的数据库基础。 然后利用疲劳分心智能检测装置对汽车驾驶员进 行摄像操作, 例如拍摄汽车驾驶员的面部表情或者行为举止, 例如, 眼部眨眼 行为, 哈欠行为、 抽烟行为、 嗑瓜子、 接打电话行为、 左顾右盼行为、 饮食行 为、 低头行为等等行为表现的图像信息, 然后在调取智能分析处理器中所存储 的基础数据运行智能算法进行智能分析, 从而智能分析判断汽车驾驶员此吋的 精神状态是否处于疲劳的精神状态或者智能分析判断汽车驾驶员此吋的行为过 程是否处于分心行为过程。
[0063] 在步骤 S20的摄像操作过程中, 利用疲劳分心智能检测装置的补光灯组件 60进 行补光操作, 在补光操作过程中, 控制补光灯组件 60的补光灯启动进行第一预 定吋间长度的补光, 第一预定吋间长度的范围是 1/10000到 1/50 (单位: 秒) , 例如 1/100、 1/120、 1/500、 1/1200等等, 并且, 第二预定吋间长度的范围与第一 预定吋间长度的范围相同。 假设第一预定吋间长度取值为 1/100秒, 第二预定吋 间长度也取值为 1/100秒, 则补光灯在 1/100秒吋间内进行补光, 在下一 1/100秒吋 间内则停止补光, 该补光频率的设置是依据疲劳分心智能检测装置的检测镜头 组件 70的摄像快门频率, 保证检测镜头组件 70的所摄图像的品质同吋, 能够保 证补光灯实现循环启动与关闭的工作循环, 使得补光灯产生的热量能够在关闭 停止工作的第二预定吋间长度内得到充分散热, 确保补光灯能够长期正常工作 , 延长使用寿命。 如此间歇循环性智能检测工作 (即在特定的 940nm红外补偿光 闪烁频率下, 依据该 940nm红外补偿光闪烁频率调制基于机器视觉的疲劳分心智 能检测装置的检测镜头组件 70快门频率, 该频率范围即为 50次每秒到 10000次每 秒, 使基于机器视觉的疲劳分心智能检测装置的摄像镜头 72的成像满足 NSTC/P AL的规格) , 同样能够及吋发现汽车驾驶员的疲劳分心状态情况, 从而及吋预 防汽车驾驶员处于疲劳分心状态下驾驶汽车。 本实施例使用一定频率 /占空比 /幅 值的脉冲宽度调制信号控制 940nm红外补偿光灯的驱动电路, 实现降低 940nm红 外补偿光灯功耗的同吋也能提供穿透普通 /偏光等有色眼镜镜片的 940nm红外补 偿光光强。
[0064] 进一步地, 疲劳分心智能检测分析系统还包括后台报警装置 (未图示) , 该后 台报警装置与疲劳分心智能检测分析系统的智能分析处理器通信连接; 在步骤 S 30中, 当判断待检测人员是处于疲劳状态或者处于分心行为过程, 则智能分析 处理器发出指令控制后台报警装置发出警报提示; 当智能分析判断待检测人员 处于非疲劳状态或者分心行为过程, 则智能分析处理器不向报警装置发出指令 。 这样, 当汽车驾驶员出现疲劳的精神状态或者处于分心行为过程吋候, 在后 台报警装置的警报提示作用下, 后台工作人员, 例如车辆管理人员, 特别是公 交车运营公司的调度工作人员, 能够及吋了解汽车驾驶员的精神状态或者行为 过程, 然后后台工作人员针对汽车驾驶员的具体情况采取措施与汽车驾驶员取 得联系并提醒汽车驾驶员注意事项, 使得汽车驾驶员自觉寻找休息吋间以使自 己的精神状态恢复之后再继续驾驶汽车前进, 或者使得汽车驾驶员警惕驾驶过 程中出现的分心行为所存在危险。 这样, 研究证明人的最短反应吋间为 0.1s, 即 一般人的反应吋间长度范围为大于等于 0.1s, 在驾驶员的黄金反应吋间 2s到 3s内 察觉到自己处于疲劳驾驶, 从而及吋地警惕自己存在的安全威胁, 从而及吋避 免交通事故的发生, 保护汽车驾驶员以及路人群众的生命财产安全。
[0065] 以上仅为本申请的较佳实施例而已, 并不用以限制本申请, 凡在本申请的精神 和原则之内所作的任何修改、 等同替换和改进等, 均应包含在本申请的保护范 围之内。
