操作部 11 : 用于用户进行各种指示操作如记录操作(如动态记录按键 1 ), 动态记录暂停 /继续 (如暂停键 2 ) 的操作, 或者输入设定信息如记录帧频等各种操作, 控制部 10根据操 作部 11的操作信号, 执行相应的程序。 操作部 11由图 2中所示的动态记录键 1 (配置为用 于进行动态记录操作)、 暂停键 2、 标记键、 十字键等构成。 此外, 也可采用触摸屏或语音识 别部件 (未图示) 等来实现相关的操作。
控制部 10控制了热像装置 13的整体的动作, 闪存 9中存储有用于控制的程序, 以及各 部分控制中使用的各种数据。 控制部 10例如由 CPU、 MPU、 S0C、 可编程的 FPGA等来实现。 所述控制程序使控制部 10执行多种模式处理的控制, 接通电源后控制部 10进行内部电路的 初始化, 而后进入普通模式, 即基于连续拍摄获得的热像数据帧显示动态的红外热像, 在此 状态, 控制部 10监视是否按照预定条件切换到了其他模式的处理, 如有则进入相应的处理控 制。 当检测到进入动态记录模式, 则进入相应的动态记录处理控制。 以下将对动态记录模式 进行说明, 在本实施例中, 控制部 10作为选择部, 显示控制部、 记录部的实例。 并且, 在闪 存 9中预先存储了包含如图 4所示的对应了变电站 1的被摄体信息的任务数据文件。 参照图 3来说明动态记录模式的控制步骤。
步骤 A01, 将通过拍摄部 1拍摄获得的热像数据帧传送到临时存储部 6;
步骤 A02, 显示控制部控制, 使显示部 4显示所获取的热像数据帧生成的红外热像及规 定数量的被摄体信息获得的被摄体指示信息。
具体而言, 一种实施方式, 控制图像处理部 2将拍摄获得的热像数据帧生成红外热像的 图像数据, 与基于闪存 9中所存储的如图 4所示的被摄体信息, 将其中规定数量的被摄体信 息生成被摄体指示信息的图像数据, 进行合成; 将合成的图像数据存放在临时存储部 6; 而 后, 控制将该合成的图像数据显示在显示部 4。 如图 5示意的显示界面所示。
当使用者进行了对滚动条的操作, 则根据调整量和滚动方向, 来重新确定规定数量的被 摄体信息。 其中, 控制部 10判断使用者是否进行的调整操作, 例如, 是否进行了拖动了如图 6中所示的滚动条 600进行了被摄体指示信息的显示调整, 或者, 使用者通过操作部进行了 翻页的调整操作, 如有, 则根据使用者对滚动条的调整量, 来确定调整后的规定数量的被摄 体信息, 而后将对应的被摄体指示信息进行显示。
优选的方式, 显示控制部将被摄体信息中用来生成被摄体指示信息的规定信息, 按照规 定位置进行分层显示。 具体而言, 显示控制部具有分层结构分配单元, 用于分配分层结构的 层次及各层次对应的属性信息; 基于存储介质中存储的被摄体信息的属性信息, 将被摄体信 息的属性信息按照分层结构分配单元分配的分层结构的层次及各层次对应的属性信息进行显 示。 例如图 6显示界面中的被摄体指示信息显示窗口 601所示的, 显示控制部将被摄体信息 按照代表变电站、 设备区、 设备类型及相别的规定属性的属性信息分为三层按照规定位置显 示; 与图 5中显示界面中的被摄体指示信息显示窗口 501相比, 显然, 同一排的字数减少, 使用者便于观察和选择。
其中, 根据被摄体信息所获得的被摄体指示信息, 可以是被摄体信息的全部或规定的部 分信息来获得, 可预先规定被摄体信息中用于获得被摄体指示信息的信息的构成。
步骤 A03, 判断是否有动态记录指示, 当使用者按下的动态记录键 1, 则进入下一步; 步骤 A04, 判断是否选择了被摄体信息, 如否, 则跳到步骤 A06; 如是, 则进入步骤 A05。 其中, 对被摄体信息的选择, 可以是在动态记录前进行, 也可以在动态记录中进行, 或 还可以暂停动态记录, 进行被摄体信息的选择, 而后再恢复动态记录; 例如当使用者根据对 拍摄现场的被摄体 "变电站 1设备区 1设备 1B相" 的认知, 例如核对现场的设备指示牌, 通过操作部 11对图 6中的 601所显示的 "变电站 1设备区 1设备 1B相"予以选择, 选择部 (控制部 10 ) 响应使用者的选择操作, 就选择了与该被摄体指示信息对应的被摄体信息, 例 如将所选择的被摄体信息"变电站 1设备区 1设备 1B相"保持在临时存储部 6的规定区域 (用 于保持所选择的被摄体信息的规定区域),其中,当有之前所选择的被摄体信息时将予以替换; 当在该规定区域中保持有被摄体信息, 则代表该被摄体信息为所选择的被摄体信息; 如无, 则代表未选择被摄体信息。 或也可将所选择的被摄体信息附加标识以区分其他被摄体信息。
进一步, 显示控制部控制特别显示该被摄体信息获得的被摄体指示信息。 在此, 特别显 示, 例如以使用者可从规定数量的被摄体指示信息中认知所选择的被摄体指示信息的方式, 来显示该被摄体指示信息。 如采用便于使用者辨别的显示位置、 颜色、 背景、 大小、 字体、 内同、 文字说明等的不同来作为区别于其他的被摄体指示信息的特别显示方式。 如图 6中的 被摄体指示信息显示窗口 602所示, 控制部 10控制, 使用者所选择的 "设备 1B相" 的下划 线标记, 以区别于其他的被摄体指示信息。 还如将所选择的被摄体信息获得的被摄体指示信 息叠加在红外热像中, 如图 6中的热像显示窗口 602所示。 并且, 特被显示的被摄体指示信 息, 其内容可以不同与其他被摄体指示信息, 例如可以包含如生成厂家等更多的信息, 但也 可以比被摄体指示信息少, 例如仅包含 "B相"。
显然, 也可以选择变电站 1、 或设备区 1等信息作为被摄体信息。
步骤 A05, 进行关联了被摄体信息的动态记录处理; 例如将从临时存储部 6的规定区域 中读取所要经历记录处理的热像数据帧, 与所选择的被摄体信息进行关联, 写入在存储介质 中创建的动态热像文件中。
其中, 与可见光的摄像不同, 由于热像拍摄获得的热像数据帧主要用于后续的分析, 保 证后续基本的回放动态效果即可, 因此, 可在较低的帧频(通常可以 3-15帧 /秒的记录帧频) 进行记录, 由此, 可确保对数据量较大的热像数据帧的动态记录处理并降低处理器件的负担。 因此, 优选的实施方式, 控制部 10作为记录部, 用于响应动态记录指示, 按照规定记录帧频 连续记录所获取的热像数据帧。 至非易失性存储介质 (如闪存 9中) 中。 具体而言, 一种实 施方式, 在规定的记录定时 (例如录制帧频 6帧 /秒时, 1/6秒) 到来之时, 从临时存储部 6 所存储的热像数据帧中选择并读取进行记录的热像数据帧, 例如从临时存储部 6的规定区域 中读取即时拍摄获得 (最新传送到临时存储部 6) 的热像数据帧, 而后, 进行规定处理如修 正、 插值、 剪切、 压缩处理等其中之一或多个的处理, 将热像数据帧及所选择的被摄体信息 或还包括必要的附加信息 (如热像数据帧的时间、 拍摄的辐射率、 环境参数温度、 湿度、 拍 摄距离、 规定的处理算法或还包括与处理算法相关的参数等) 写入在存储介质如闪存 9中动 态记录起始创建的动态热像文件中。
此外, 规定的记录帧频也可采用抽取的方式来实施, 例如假定拍摄获取得热像数据帧的 帧频为 30HZ, 规定的记录帧频为 6帧 /秒时, 可以按照 5帧中抽取一帧的方式来实现规定的记 录帧频。
其中, 热像数据帧进行规定的处理后获得的数据 (规定的处理例如修正、 插值、 伪彩、 转换为温度数值、 降像素、 压缩等处理的一种或同时多种); 可以是这些情况获得的数据之一 或多种, 如同时记录热像数据帧获得的各像素的温度值和红外热像的图像数据。
所选择的被摄体信息有关的信息, 例如, 可以是作为所选择的被摄体信息的被摄体信息 的所有信息, 或其中部分信息, 例如可记录"变电站 1设备区 1设备 1B相", 但也可记录"设 备区 1设备 1B相", 也可是该被摄体信息中未用于显示的其他信息, 例如该被摄体信息中还 具有其它的编号、 型号、 ID号等信息, 虽未显示, 但也可保存编号、 型号、 ID号之一或多个 的信息。 可预先规定被摄体信息中用于记录的信息的构成。
被摄体信息等附加信息可作为对应的热像数据帧的头部信息写入该热像数据帧, 此外, 也可有与上述不同的被摄体信息的关联方式, 例如, 也可将步骤 A05所记录的热像数据帧的 帧时序信息, 与被摄体信息一起, 作为管理信息, 作为必要的文件附加信息的构成部分, 写 入动态热像文件; 或者生成与该动态热像文件关联的信息文件或索引文件, 在索引文件中包 含了关联了被摄体信息的帧的帧时序信息及所关联的被摄体信息。控制部 10可生成该信息文 件或索引文件。 此外, 当选择的被摄体信息针对整个动态热像文件时, 还可根据选择部所选 择的被摄体信息来生成动态热像文件名; 所述记录部具有文件名生成单元, 用于生成热像文 件的文件名, 其生成的热像文件的文件名中包含了选择部选择的被摄体信息的有关的信息; 例如生成的热像文件名: 变电站 1 设备区 1 设备 1B 相 . IRV, 进一步, 与日期、 时间信息 " 20120222 "结合生成文件名, 例如变电站 1-设备区 1_设备 1-B相 -20120222. IRV; 关联记 录的实质是记录便于后续的批处理分析所需要的信息, 而文件名中包含了被摄体信息使使用 者便于査看。
步骤 A06, 进行动态记录处理, 例如将从临时存储部 6的规定区域中读取所要经历记录 处理 (例如最新传送到临时存储部 6) 的热像数据帧写入在存储介质中创建的动态热像文件 中。 优选的实施方式, 所述记录部, 用于按照规定记录帧频连续记录拍摄部连续拍摄获取的 热像数据帧, 至非易失性存储介质 (如闪存 9中) 中。
步骤 A07, 控制部判断是否结束动态记录处理, 如否, 则回到步骤 A01, 例如体现了被摄 体指示信息 (当有选择的被摄体指示信息, 则包含特别显示的该被摄体指示信息) 与动态的 红外热像 (连续合成) 共同显示, 其中, 使用者还可重新选择新的被摄体信息, 当选择了新 的被摄体信息, 在步骤 A05, 将所选择的被摄体信息与热像数据帧关联记录。
如是, 则在步骤 A08, 将必要的文件附加信息 (如结束标识等) 写入动态热像文件, 完 成动态热像文件。
如上所述, 使用者在拍摄中, 当选择了被摄体信息, 则在选择了该被摄体信息的期间, 将所连续记录的热像数据帧与该被摄体信息关联记录, 因此能方便地记录被摄体信息; 由于 同时显示规定数量的被摄体信息, 因此, 便于使用者根据现场设备来选择被摄体信息, 使用 十分方便。
实施例 2
实施例 2的热像装置 13, 在正式拍摄之前, 在闪存 9中预先存储了包含如图 4所示的对 应了变电站 1的被摄体信息的任务数据文件,此外,还存储了包含其他变电站的被摄体信息的 任务数据文件。 本应用场景例如对变电站 1的被摄体 1进行拍摄。 以往, 由于检测的目的不 一样, 有全站所有被摄体的检测, 也有特定类型被摄体的检测, 这些特定类型被摄体分布在 不同设备区, 需要使用者去寻找, 非常不便。 如将被摄体信息作为过滤条件, 能便于使用者 拍摄。
参照图 7来说明动态记录模式的控制步骤。
步骤 B01, 任务确定部确定被摄体信息, 所确定的被摄体信息用于从中选择被摄体信息; 详见图 11的说明。
步骤 B02, 将通过拍摄部 1拍摄获得的热像数据帧传送到临时存储部 6;
步骤 B03, 显示控制部控制, 使显示部 4显示所获取的热像数据帧生成的红外热像, 并 基于任务确定部所确定的被摄体信息, 显示其中的规定数量的被摄体信息获得的被摄体指示 信息。
步骤 B04, 判断是否有动态记录的指示, 当使用者按下的动态记录键, 则进入步骤 B05; 步骤 B05, 判断是否选择了被摄体信息。 如否, 则跳到步骤 B07; 如是, 则进入步骤 B06。 类同于步骤 A04, 省略了说明。 步骤 B06, 进行热像数据帧与被摄体信息关联的动态记录处理。 类同于步骤 A05, 省略 了说明。
步骤 B07, 进行热像数据帧的动态记录处理; 类同于步骤 A06, 省略了说明。
步骤 B08, 控制部判断是否结束, 如否, 则回到步骤 B02, 使用者还可重新选择新的被摄 体信息, 当选择了新的被摄体信息, 在步骤 B06, 将所选择的被摄体信息与热像数据帧关联 记录。
如是, 则在步骤 B09, 将必要的文件附加信息 (如结束标识等) 写入动态热像文件, 完 成动态热像文件。
参考图 11, 来说明任务确定部对规定数量的被摄体信息的确定处理。
步骤 S101 , 显示闪存 9中的任务数据文件的文件名, 而后进入步骤 S102。通常可以把不 同的拍摄目的地中的被摄体分配为若干个任务数据文件, 例如根据变电站, 将每个变电站的 设备名称预先编制在一个任务数据文件。
步骤 S102, 判断使用者是否从中选择了一个, 如选择了其中一个或多个, 则进入步骤
S103; 如无, 则回到步骤 S101。
步骤 S103, 接着, 根据使用者的选择就确定了拍摄有关的任务数据文件。
步骤 S104,接着,任务确定部判断是否有规定的过滤条件。如有则进入步骤 S105。如无, 则将所选择的任务数据文件中的被摄体信息予以确定。
步骤 S105, 如有过滤条件, 则根据规定的过滤条件, 确定任务数据文件中符合过滤条件 的被摄体信息。
上述实施方式, 基于多个任务数据文件。 如果被摄体信息以数据库, 或一个任务数据文 件的形式进行存储, 也可省略步骤 S101-S103。
优选的, 热像装置 13具有过滤条件设置部 (例如由控制部 10、 操作部 11、 显示部 4构 成), 用于使用者设置过滤条件; 具有任务确定部, 用于基于存储介质中存储的被摄体信息, 根据所述过滤条件, 来确定符合过滤条件的被摄体信息。
参考图 8来说明过滤条件的设置操作。当使用者进入菜单模式,选择其中的"过滤设置", 显示部 4显示如图 8所示例的过滤条件设置栏界面。
过滤条件由与过滤条件有关的关键字和过滤逻辑关系等构成。 所述过滤条件设置部包括 关键字确定单元、逻辑确定单元,其中,关键字确定单元,用于确定与过滤条件有关的关键字; 逻辑确定单元, 用于确定与过滤条件有关的关键字的过滤逻辑关系。
与过滤条件有关的关键字, 可以是一个关键字, 也可以是多个关键字; 其中, 多个关键 字包括代表关键字范围的情况, 如数字范围、 字母范围、 时间范围等。 此外, 当被摄体信息 中具有与被摄体有关的归属单位、 分类等级 (如电压等级、 重要等级等)、 型号、 制造厂商、 性能和特性、 过去的拍摄或检修的履历、 制造日期、 使用期限等各种信息时, 均可从中确定 关键字来设置过滤条件, 但这些信息并不一定用于生成特别显示的被摄体指示信息。
关键字确定单元, 用于确定与过滤条件有关的关键字; 例如, 可以是如下一种或多种实 施方式结合来确定与过滤条件有关的关键字。 一种实施方式, 例如, 预存的关键字, 基于使 用者的选择来确定与过滤条件有关的关键字。 一种实施方式, 例如, 默认的与过滤条件有关 的关键字之一或全部。 一种实施方式, 例如, 由使用者录入关键字, 将使用者录入的关键字 确定为与过滤条件有关的关键字。一种实施方式, 例如, 提供供选择的关键字属性的选择项, 基于使用者选择的关键字属性, 将符合该关键字属性的关键字确定为与过滤条件有关的关键 字。 一种优选的实施方式, 基于存储的被摄体信息, 査询获得被摄体信息中规定属性的属性 信息的关键字, 基于使用者的选择来确定与过滤条件有关的关键字。
以使用者拍摄 "设备 1 "类型的被摄体为例来说明过滤条件的具体设置操作。 具体而言, 显示部 4显示如图 8示例的过滤条件设置界面, 变电站 803、 设备区 804、 设备类型 805等被 配置为代表规定属性的属性信息的关键字査询的关键字菜单项。 当存储如图 4所示的被摄体 信息时, 控制部 10基于使用者根据本次拍摄 "设备 1 "而选中的设备类型 805, 査询存储介 质中存储的被摄体信息,获得规定属性(设备类型)的属性信息的关键字 "设备 1、设备 2、 ... ", 使显示列表 806, 使用者从中选择其中的 "设备 1 ", 关键字确定单元, 确定 "设备 1 "为与 过滤条件有关的关键字。
此外, 也可将在先的关键字菜单项的所选择的属性信息作为后续关键字菜单项的过滤条 件, 例如使用者选择变电站 803, 则显示变电站的列表, 从中选择变电站 1, 当选择设备类型 805, 将仅显示符合变电站 1中的设备类型的列表。
逻辑确定单元, 用于确定与过滤条件有关的关键字的过滤逻辑关系; 过滤逻辑关系是指 过滤条件有关的关键字为一个关键字时, 该关键字的过滤是非关系; 过滤条件有关的关键字 为多个关键字时, 为多个关键字相互之间的与、 或、 非逻辑关系与过滤是非关系的结合; 过 滤是非关系和关键字之间的逻辑关系可以是默认的, 也可以根据使用者设置来确定。
在图 8中, 拍摄条件的 "是" 801和 "非" 802选项, 用于设置过滤是非关系; 当选择了 "是", 结合关键字 "设备 1 "生成的过滤条件用于后续査找并确定符合 "设备 1 " 的被摄体 信息作为拍摄任务; 当选择了 "非", 结合关键字 "设备 1 "生成的过滤条件用于后续査找确 定符合非"设备 1 "的被摄体信息。在本例中,逻辑确定单元根据默认的过滤是非关系为 "是" 将过滤是非关系确定为 "是"。 而后, 当使用者通过操作部 11进行确定, 在任务确定时, 将 査找符合关键字 "设备 1 " 的被摄体信息作为确定的被摄体信息。 显然, 也可以选择多个关 键字来作为过滤条件。
过滤条件, 可以根据使用者设置来确定(未图示), 或也可以是预先存储的, 根据使用者 设置生成的过滤条件可记录在临时存储部 6或记录在闪存 9等中例如作为配置文件作为之后 的使用。
图 9示意的被摄体信息, 代表了任务确定部 (控制部 10), 用于基于存储介质中存储的 (表 4中的) 被摄体信息, 根据过滤条件 "设备 1 ", 来确定符合过滤条件的被摄体信息而获 得的被摄体信息。
图 10所示的显示界面所显示的根据过滤后的被摄体信息获得的被摄体指示信息。 显然, 使用者需要选择的被摄体指示信息仅限于 "设备 1 " 的设备类型, 使操作简单, 且不易失误。
如上所述, 基于过滤条件的设置, 使用者可以对拍摄对象进行预先的过滤, 使供选择的 被摄体指示信息减少, 使操作简单。
实施例 3
实施例 3的热像装置 13, 用于在暂停动态记录和 /或冻结显示的状态下, 进行被摄体信 息选择有关的选择操作。
参见图 12来说明热像装置 13的控制流程, 步骤如下:
步骤 C01, 获取热像数据帧, 将拍摄部 1拍摄获得的热像数据帧传送到临时存储部 6; 步骤 C02, 显示控制部控制, 使显示部 4显示所获取的热像数据帧生成的红外热像, 并 显示规定数量的被摄体信息获得的被摄体指示信息。
步骤 C03, 判断是否有动态记录的指示, 当使用者按下的动态记录键, 则进入下一步; 步骤 C04, 判断是否选择了被摄体信息。 如否, 则跳到步骤 C06; 如是, 则进入步骤 C05。 步骤 C05, 进行热像数据帧与被摄体信息关联的动态记录处理。 类同于步骤 A05, 省略了说 明。
步骤 C06, 进行热像数据帧的动态记录处理; 类同于步骤 A06, 省略了说明。
在步骤 C07, 判断是否有暂停指示? 当使用者按下暂停键, 则进入下一步;
步骤 C08, 暂停动态记录处理;
步骤 C09, 进行被摄体信息的选择;
步骤 C10, 判断是否结束, 如未结束, 则返回步骤 C01, 并在步骤 C05, 将热像数据帧及 新选择的被摄体信息写入在存储介质中创建的新的动态热像文件中。
如结束, 则在步骤 Cl l, 将必要的文件附加信息 (如结束标识等) 写入动态热像文件, 完成动态热像文件。
显然, 由于在暂停动态记录的情况下, 进行被摄体信息的选择, 从而能够降低所记录的 热像数据帧的冗余数据量; 并且, 在暂停动态记录时, 显然, 显示部可以显示为响应暂停指 示的时刻, 所保持的热像数据帧获得的红外热像及规定数量的被摄体指示信息; 或显示为动 态的红外热像及规定数量的被摄体指示信息; 或切换为仅显示规定数量的被摄体指示信息。 在上述步骤中也可省略步骤 C02。
实施例 4
虽然本发明在实施例 1中用于具有拍摄功能的热像装置 13, 但对于本发明而言拍摄获得 热像数据帧的功能不是必不可少的, 本发明还可应用于从外部接收和处理热像数据帧的热像 处理装置等。 实施例 3以热像处理装置 100作为热像录像装置的实例。
参考图 13为热像处理装置 100和热像装置 101连接构成的热像录像系统的一种实施的电 气结构的框图。
热像处理装置 100具有通信接口 1、 辅助存储部 2、 显示部 3、 RAM4、 硬盘 5、 操作部 6 通过总线与上述部件连接并进行整体控制的 CPU7。 作为热像处理装置 100, 可以例举个人计 算机、 个人数字助理、 与热像装置配套使用的显示装置等作为例子。 热像处理装置 100, 基 于 CPU7的控制,通过通信接口 1接收与热像处理装置 100连接的热像装置 101输出的热像数 据帧。
通信接口 1, 用于连续接收热像装置 101输出的热像数据帧; 其中, 包括接收通过中继 装置来发送的 (由热像装置 101输出的热像数据帧通过中继装置来发送的) 热像数据帧; 同 时,还可作为对热像装置 101进行控制的通信接口。在此,通信接口 1包括热像处理装置 100 上的各种有线或无线通信接口, 如网络接口、 USB接口、 1394接口、 视频接口等。
辅助存储部 2, 例如 CD-R0M、 存储卡等存储介质及相关的接口。
显示部 3如液晶显示器, 显示部 3还可以是与热像处理装置 100连接的其他显示器, 而 热像处理装置 100自身的电气结构中可以没有显示器。
RAM4作为对通信接口 1接收的热像数据帧进行临时存储的缓冲存储器, 同时, 作为 CPU7 的工作存储器起作用, 暂时存储由 CPU7进行处理的数据。 硬盘 5中存储有用于控制的程序, 以及控制中使用的各种数据。 操作部 6, 用于进行操作。 CPU7控制了热像处理装置 100的整 体的动作, CPU7还执行了图像处理部的功能, 用于对接收的热像数据帧实施规定的处理而获 得红外热像的图像数据, 规定的处理如修正、 插值、 伪彩、 合成、 压缩、 解压等,进行转换为 适合于显示用、 记录用等数据的处理。 其中, CPU7根据热像数据帧的不同格式, 一种实施方 式, 例如, 当接收的热像数据帧为压缩的热像 AD数据, 规定的处理如 CPU7对获取部接收的 热像数据帧进行解压并进行相应的规定处理; 一种实施方式, 对压缩热像 AD数据解压后相应 的规定处理如伪彩处理, 来获得红外热像的图像数据, 此外, 规定的处理还如在解压后的热 像数据帧进行校正、 插值等规定的各种处理。 另一种实施方式, 例如, 当接收的热像数据帧 本身已是压缩的红外热像的图像数据, 则解压来获得红外热像的图像数据。又一种实施方式, 例如, 当通信接口 1接收的是模拟的红外热像时, 控制将经相关 AD转换电路 AD转换后获得 数字的红外热像的图像数据, 传送到临时存储部 6。
热像装置 101可以是各种类型的热像拍摄装置, 其用于对被摄体进行拍摄, 并输出热像 数据帧。 见图 12中热像装置 101的电气框图, 由通信接口 10、 拍摄部 20、 闪存 30、 图像处 理部 40、 RAM50、 CPU60等构成。 其中, CPU60控制了热像装置 101 的整体的动作, 闪存 30 中存储了控制程序以及各部分控制中使用的各种数据。拍摄部 20包括未图示的光学部件、驱 动部件、 热像传感器、 信号预处理电路, 用于拍摄获得热像数据帧。 该热像数据帧暂时存储 在 RAM50中, 而后经图像处理部 40 (如 DSP) 经过规定处理 (如压缩处理等) 后获得热像数 据帧, 经通信接口 10输出。 在此, 热像装置 101用于拍摄并输出的热像数据帧, 其作用类似 热像装置 13中的拍摄部 1。
图 14为热像处理装置 100和热像装置 101连接构成的热像处理系统的一种实施的示意 图。 热像装置 101采用云台等架设在检测车辆, 经由专用电缆等通信线、 或有线和无线的方 式构成的局域网等方式与热像处理装置 100进行连接。 使用者通过热像处理装置 100进行观 看和监测被摄体热像。 热像装置 101, 与热像处理装置 100连接构成实施方式中的热像录像 系统, 用于对被摄体进行拍摄。 从热像装置 13 中除去拍摄部 1 以外的结构与热像处理装置 100 大致相同, 显然通过接收获取热像数据帧, 同样适用本实施例。 因此省略了实施方式的 说明。 显然, 热像处理装置 100可与各种具有热像拍摄功能的热像装置如各种手持式的热像 装置配套使用。
上述实施例为较优的实施方式, 当然, 实施本发明的实施方式的任一产品并不一定需要 同时达到以上所述的所有优点。 需要注意的是, 本实施例中, 以数量较少的被摄体信息来进 行示例说明, 在实际的红外检测工作中, 被摄体数量众多, 采用本发明的实施方式带来的效 果显著。 此外, 实施例中以电力行业的被摄体应用作为场景例举, 也适用在红外检测的各行 业广泛运用。
由于热像数据帧的数据量较大, 因此, 为减少所记录的热像数据帧的数据量, 进一步, 控制部 10作为暂停控制部, 用于响应规定的操作 (如按下暂停键), 暂停动态记录处理, 并 在记录暂停的状态下, 响应规定的操作(如再次按下暂停键), 继续动态记录处理。 便于后续 的动态热像文件的管理和处理。 此外, 还可进一步规定动态热像文件的大小, 即判断是否达 到规定的动态热像文件大小, 如是, 则完成动态热像文件, 并创建一个新的动态热像文件, 后续所记录的热像数据帧记录在新创建的动态热像文件中。 显然, 规定的记录帧频并非必须 是固定的, 例如优选的方式, 热像装置 13还具有记录帧频控制部, 用于在记录处理的速度达 不到所设定的记录帧频的情况下, 自动来进行记录帧频的自适应控制, 或还近一步来提示使 用者改变记录帧频。
此外, 当热像记录装置具有第二获取部, 用于获取其他影像, 所述记录部, 将其他影像 例如可见光等与所标记的热像数据帧关联记录。 这样便于后续的査看分析。
在优选的实施方式中, 热像数据帧的附加信息等也可以与对应帧的帧时序关联, 全部临 时存储在临时存储部中, 在结束动态记录时, 一次性全部写入动态热像文件中, 后续分析时 可快速査找相应附加信息例如被摄体信息等。
动态记录并不限于生成动态热像文件; 在一个例子中, 可将连续记录的热像数据帧各自 生成包含一个热像数据帧及相关附加信息的热像图片文件, 并存放在特定的文件夹中, 其中 的标记帧所生成的文件的扩展名与其他帧不同。
并且, 也可作为带有拍摄功能的热像装置、 或热像处理装置中的一个构成部件或功能模 块, 也构成本发明的实施方式。
