Plant roots play an important role in fixing plants and obtaining water and nutrients, but the limitation of soil unobservability has brought certain difficulties to the study of root ecology.

Description

一种原位扫描装置
技术领域
本发明涉及图像数据采集领域, 具体涉及一种原位扫描装置。
背景技术
越来越多的领域需要用到原位扫描装置, 例如, 土壤分析、 岩土分析、 地质考古、 深层泥沼分析、 植物根系研究等。 尤其是植物根系的研究。 植物 根系对固定植株和获得水分和养分起重要作用,但是土壤不可观测性的限制, 给根系生态学的研究带来一定的困难。 因此, 找到原位观察根系生长的方法 对研究根系生态学就显得尤为重要。 目前植物根系原位扫描技术被认为是研 究根系生态学最有前途的方法。
但是, 目前常用根系研究方法是洗根法, 将根系从土壤中挖出来洗净后 用扫描仪进行扫描测量。 此方法在挖掘、 洗根的过程中会造成根系位置的变 化, 结构的损伤和断裂。 并且挖出植物根系后植物就会死亡, 该方法不能连 续测量。
中国发明专利申请号 201210231267. 2公开了一种土壤栽培条件下采用植 物生长室的方法测定植物的根系。该方法以放射状透明容器为盆栽生长容器, 每个分室间隔一定距离, 然后通过相机将根系图像拍摄下来后用图片分析软 件统计根系特征。 该方法的缺点也在于不是在土壤中原位进行测量, 植物根 系生长被人为局限在一个非常狭窄空间中, 不能真实反映出植物根系的生长 状态。
文献期刊 《生态学报》 中论文 《微根窗技术及其在植物根系研究中的应 用》 提及了一种利用照相机连接控制盒和电脑拍摄地下根系的方法, 但该方 法必须连接电脑使用, 不能适用于田间环境。 另外在非常短的距离内拍摄图 像会有严重的鱼眼效益, 导致图像变形失真严重, 致使获得的数据不准确。
美国 CID Bio-Sc ience, Inc公司生产的 CI-600
( http : //www. cid-inc. com/ cn/root-image/ci-600. php )植物根系原位扫描 装置由于机械结构的原因不能完成完整的 360度扫描, 只能扫描到 355度。 因 为在 CI-600的扫描结构中有一标记起始点和终止点的标记杆, 旋转机构从此 杆的位置开始扫描, 当扫描接近一周后接近开关抵达此标记杆而停止扫描, 之后旋转机构再反向旋转扫描, 总之始终只能扫描 355度的图像, 不能实现完 整的一周扫描。 CI-600的电路设计没有考虑田间野外使用的环境要求, 使用 时必须连接电脑进行工作, 没有电池供电, 没有文件存储功能, 致使操作者 在野外必须携带笔记本工作, 而笔记本的电池除了给笔记本供电以外还有为 设备供电, 实际工作时间非常短, 完全不能满足野外使用的要求。 CI-600旋 转部件和固定部件之间有较大的缝隙, 灰尘、 土粒非常容易进入从而导致不 能工作和寿命缩短。
在松软泥沼中对各层泥土取样进行研究往往也是有缺陷的, 需要对各层 泥沼中分布的沉积物进行研究, 以考察沉积年限、 沉积过程, 则需要沉积物 保持在原位进行扫描。 打孔之后, 泥土也会灌入孔中无法考察。 有效的方法 是插入透明管到泥沼中, 形成圆筒状, 对泥沼的圆筒内壁即透明管的外壁进 行图像采集。 对于需要原位考察的土壤研究、 地壳考古, 获取原位图像数据 也是非常重要的。 为了能够获取原位图像数据, 需要一种能够在原位进行数 据采集的设置。
为此, 本发明提出一种原位扫描装置, 可用于在田间野外环境下在土壤 中原位对植物根系进行扫描测量, 也可以用于泥沼、 岩土、 土壤、 地质等研 究。 发明内容

根据本发明的另一个实施方式, 其中, 控制系统中可以设置有通信模块。 如图 2所示, 通信模块可以包括线通信模块 210和无线通信模块 211。
其中,有线通信模块 210包括但不限于 USB、 RS232串口、 RS485串口、 RS242 串口、 并口、 I2C、 CAN, 网口等多种组合或其中一种通过线缆传输数据的结 构。

根据本发明的另一个实施方式, 其中, 控制系统可以设置有液晶显示模 块 212, 扫描部 100侧面设置有与该液晶显示模块位置相对应的显示窗口 105, 参考图 1和图 2。
图 3是根据本发明的另一个实施方式的原位扫描装置的控制手柄。在该实 施方式中, 原位扫描装置还可以包括控制手柄 315, 其用于与控制系统以无线 或有线方式进行连接, 并实现控制。控制手柄 315上可以设置有数据传输开关 316和开始 /停止扫描开关 317。 数据传输开关 316用于控制扫描装置主体上的 控制系统与其他终端之间的数据传输。例如, 通过通信模块与电脑进行通信, 实现扫描的数据图像从控制系统的存储单元或存储接口上插放的存储卡上传 至电脑中进行浏览和后续处理。 还可通过无线通信模块与其他有无线传输功 能的设备进行通信, 实现扫描的数据图像从系统的存储单元或存储接口上插 放的存储卡上传至电脑、 笔记本、 掌上设备、 智能手机或嵌入式系统中进行 浏览和处理。 开始 /停止扫描开关 317用于启动或停止扫描装置。

根据本发明的另一实施方式, 其中, 控制系统还可以包括多个状态指示 灯, 用于显示控制系统中各部件的运行状态。
根据本发明的另一实施方式, 其中, 前导向部 102A和后导向部 102B上设 置有导向轮 103, 用于协助主机原位测量时在根管中平滑的进出。
根据本发明的原位扫描装置, 其中, 控制系统还可以包括: 线阵感光传 感器 202、 数据缓存(可以包括线阵数据缓存 203和面阵数据缓存 204) 、 时序 控制模块 206。
如图 1所示, 扫描部 100为原位扫描装置的重要部件, 上面带有线阵感光 传感器 101、 有线传输接口 106、 显示屏 105、 按钮 107。
如图 2所示, 中央处理器 201是整个系统的核心, 负责将面阵数据缓存 204 中的原始图像数据生成图像文件 (格式包括但不限于 JPG、 PNG、 GIF, TIF) 和格式文件 (包括但不限于 PDF、 D0C、 D0CX、 RAW) 。 将这些文件存入内置或 外置的存储单元中。通过电源模块 207管理和控制原位扫描装置中各部件的休 眠、 启动和节电运行。 接收用户的控制按钮 209、 316、 317、 107的动作来设 置系统的参数和控制系统的工作。通过电机驱动模块 208让电机以与需要的分 辨率相对应的速度匀速旋转,即可以通过控制旋转速度来适应不同的分辨率。 还可以通过中央处理器 201控制液晶显示屏 212的显示,显示系统的工作状态、 剩余电池电量、 已经存储的图像数量、 图像扫描质量信息、 存储的文件格式 等信息。通过中央处理器 201控制状态指示灯 213的亮灭提示系统的工作状态。
线阵感光传感器 202是由很多微小感光点紧密排列为一条直线的传感器, 每个感光点间距大约 28 μιη。 每个感光点前面都有一个微型透镜, 能将距离 10 mm光强收集聚焦到感光点上。感光点的核心元件是 M0S电容, 将光子转化为电 子,经过时序控制模块 206将电子转化为电流串行存储到线阵数据缓存 203中, 这样扫描到的一行图像数据便被临时记录下来,时序控制模块 206给电机驱动 模块 208运动时钟信号, 让电机旋转一个角度后, 再控制线阵感光传感器 202 进行下一行数据的扫描。这样周而复始, 系统便能扫描完一整圈 360度的根系 图像, 或为了防止旋转机构中的齿轮间隙进行超过 360度范围的根系图像扫 描; 扫描角度不限于 360度, 可以由中央处理器任意设置。
图 4是根据本发明的一个实施方式的原位扫描装置的局部结构示意图。扫 描部 100中可以设置有电机 413, 其中, 电机 413外壳 412与扫描部 100固定, 电 机转子 414与导向部 102A或 102B固定。当电机驱动模块 108给电机 413输出电信 号时电机转子 414相对电机 413转动, 而导向部件与透明管管壁是固定的, 使 得扫描部 100绕轴向旋转扫描。不同于 CI-600, 本发明在设计上没有起始和终 止点, 可以在任意位置开始和停止扫描, 起始点和终止点由中央处理器 201 通过时序控制模块 206精确控制,不存在像 CI-600有标记杆之类致使不能旋转 整周的阻挡物。
线阵数据缓存 203的作用是将线阵感光传感器 202扫描的一行图像数据临 时记录下来, 因为线阵感光传感器 202只能实现将光信号转化为电信号的功 倉 再次扫描时会将原来的信号完全覆盖, 不能将这种电信号记录下来。 线 阵数据缓存 203的特点是数据存储速度快, 但成本高, 空间小, 因此只用来将 线阵感光传感器 202的数据进行快速临时缓存。 当线阵数据缓存 203中的每收 集到完整的一行图像数据便在时序控制模块 206的时序控制下将这一行图像 数据提交给面阵数据缓存 204中进行存储,数据提交完成后便释放此段空间以 便存储新的来自线阵感光传感器 202的图像数据。
面阵数据缓存 204的作用是将来自线阵数据缓存 203中的临时数据进行较 长一段时间的存储。 其特点是读写速度适中, 空间较大, 成本适中。 面阵数 据缓存 204接收到线阵数据缓存 203提交的完整的一行图像数据后便按提交的 先后顺序连续存储起来, 系统没扫描完一个角度, 面阵数据缓存 204中增加一 行新的数据, 这样当扫描完成后, 面阵数据缓存 204中便记录下了所有原始数 据, 但这种数据也是临时数据, 系统关机断电后数据便消失了, 不能永久存 储下来。 另外这种数据是图像的原始数据, 不是通用图像格式, 不能被图像 软件识别和分析, 并且这种原始数据过于庞大, 不便于存储和传输。 因此当 扫描工作完成后面阵数据缓存 204便将整幅图像数据提交给中央处理器 201, 中央处理器 201将原始的图像数据转化为标准的图像文件或格式文件,这样存 储空间会小很多,并且可以被纵多图像软件或其他专用软件识别浏览和处理。
存储单元或接口 205的作用是将处理完成的图像文件或格式文件存储起 来, 以便上传到电脑或其他终端设备上。 其特点是容量非常大, 成本较低, 即使断电后文件也不会丢失。
时序控制模块 206的作用是为线阵感光传感器 202和电机驱动模块 208提 供时钟信息, 让其按设定的频率采集图像信号和旋转。
电源模块 207的作用是管理和控制所述原位扫描装置中各部件的休眠、启 动和节电运行, 将输入的电压进行稳压和滤波后提供给系统各个元件, 并且 还可以包括可充电电池。 另外, 还可以接收中央处理器 201的控制休眠或自动 关机信号, 当系统开机但没有进行扫描时, 电源模块 207不会开启照明光源和 电机, 保存系统功耗在一个比较低的水平上, 当系统在一定时间内没有任何 操作时, 中央处理器 201会通知电源模块 207让其断电, 实现系统自动关机的 目的。
根据本发明的原位扫描装置可设置无线通信模块, 通过无线连接, 方便 野外操作, 可以连接的设备众多, 并且可以实现一对一或多个设备同时连接 和通信; 或者无线通信模块 211与具有通信协议转换功能的设备连接后, 实现 上述功能。
液晶显示屏 212的作用是将系统的参数显示出来, 方便操作者观察其状 态。 显示的内容包括扫描图像的分辨率、 已经存储图像的数量、 通信状态等
| H心自。
控制按钮 209的作用是让操作者控制系统的工作, 可以控制其开始 /停止 扫描, 设定扫描的分辨率, 开启 /关闭无线功能等。
状态指示灯 213的作用是将系统的实时状态以最为显著的方式提醒操作 者, 例如系统是否正在扫描中, 无线功能是否已经被开启等。
扫描部 100带有参数设置按钮 107, 方便进行测量参数的设置。
扫描部件 100与带有刻度的连接杆 108连接时,可用于确定扫描部 100在透 明筒中的位置深度。
扫描部 100与控制手柄 315通过控制线 109或无线连接,使操作者能通过控 制手柄 215控制装置开始或停止扫描, 或开启 /关闭无线通信功能。
在使用本发明的原位扫描装置时, 可以在被观测植物周围或者土壤或岩 土或其他需要研究的对象中, 用土钻打孔, 埋入底部封闭的透明管, 将连接 杆 108、 控制线 109与后导向部 102B相连, 将装置放入透明管中。 按下开始 / 停止扫描开关 317, 扫描部件 100开始做圆周扫描, 扫描完成后可以通过连接 杆 108变换装置放入的深度再次进行扫描。扫描完成后按下无线传输开关 316, 通过诸如手机、 电脑或其他终端接收扫描的图片或文件。 完成测量工作后将 装置从根管中取出, 卸下连接杆 108和控制线 109即可。
本发明虽然以较佳实施例公开如上, 但其并不是用来限定本发明, 任何 本领域技术人员在不脱离本发明的精神和范围内, 都可以做出可能的变动和 修改。 因此, 凡是未脱离本发明技术方案的内容, 依据本发明的技术实质对 以上实施例所作的任何修改、 等同变化及修饰, 均落入本发明权利要求所界 定的保护范围之内。
