请同时参阅图2,本发明还提供一种探测系统S1,图2示出了本发明一实施方式中探测系统S1的功能模块图。所述探测系统S1运行于上述的探测装置100中。具体而言,所述探测系统S1包括中央控制模块101、发射控制模块103、驱动模块105、接收控制模块107以及运算模块109。进一步地,所述探测装置100还包括存储器70(请参阅图1),所述探测系统S1的各个模块为存储在所述存储器70中并可被所述控制器10执行的可程序化的模块。
具体如下:
所述中央控制模块101用于向其余各个模块发送指令,以使各个模块协同作业,控制所述探测装置100探测其周围的障碍物信息。
所述发射控制模块103用于控制所述发射组件30发射信号。具体地,所述发射控制模块103用于控制所述发射组件30的所述发射器32向所述反射器36发射一信号。优选地,所述发射器32为激光发射器,所述信号为激光信号。

在本实施方式中,从所述反射器36射出的所述信号为激光信号,所述光电二极管52用于接收所述激光信号经所述障碍物反射后的信号并将该经所述障碍物反射后的信号转变为电信号。具体地,所述光电二极管52内置有PN结(P型半导体与N型半导体制作在同一块半导体(通常是硅或锗)基片上,在它们的交界面就形成空间电荷区称为PN结)以及电极,所述PN结用于接受入射光照,所述电极用于产生反向电压。当所述光电二极管52没有接受光照时,其内的反向电流很小(一般小于0.1微安)。当述光电二极管52受到光照时,携带能量的光子进入所述PN结后,把能量传给共价键上的束缚电子,使部分电子挣脱共价键,从而产生电子---空穴对,称为光生载流子。所述光生载流子在反向电压作用下参加漂移运动,使反向电流明显变大。光的强度越大,反向电流也越大。当所述光电二极管52电性连接于所述控制器10上时,会因所述反向电流的存在而获得电信号,所述电信号随着射入所述光电二极管52的激光信号的变化而相应变化。因此,所述接收控制模块107能够根据所述电信号的变化,判断是否存在反射的信号。
所述运算模块109用于根据所述信号经反射后的信号,计算所述障碍物相对所述探测装置100所处的方位。具体地,所述反射信号到达所述接收器50后,所述光电二极管52将所述反射后的信号转换为电信号,所述运算模块109根据所述反射器36的转动角度、所述信号的发射时间及所述反射信号的接收时间,计算所述障碍物相对所述探测装置100所处的方位。
在本实施方式中,所述探测装置100应用于障碍物检测的工作中。所述发射器32持续地向所述反射器36发射信号,同时,所述驱动器34控制所述反射器36转动,使所述反射器36将所述信号向所述探测装置100周围的多个方向发射。若所述探测装置100周围存在障碍物,则投射到所述障碍物上的所述信号会反射至所述接收器50中。所述接收器50将其接收到的经所述障碍物反射后的信号转变为电信号后,传输至所述控制器10中。所述控制器10根据所述反射器36的转动角度可判断出所述信号发射的方向,由此可判断所述障碍物所处的方向;所述控制器10还所述信号的发射时间及所述反射信号的接收时间差,计算所述障碍物与所述探测装置100之间的距离,从而可以确定出所述障碍物相对于所述探测装置100所处的方位及距离。
可以理解,在其他的一些实施例中,所述探测装置100可以应用于三维成像或三维建模的工作中。利用所述探测装置100探测其周围的障碍物上每一单位区域的相对方位信息后,构建所述障碍物的外形轮廓,即可进行三维成像或三维建模。具体地,所述发射器32持续地向所述反射器36发射信号,同时,所述驱动器34持续控制所述反射器36转动,使所述反射器36依次将所述信号向所述探测装置100周围空间内的所有方位射出。所述控制器10同时记录每一方位上的所述信号的反射距离,从而得出该方位上的障碍物与所述探测装置100之间的距离信息。然后,所述控制器10根据所述探测装置100周围空间内每一单位方位上的障碍物的信息,重建出所述探测装置100周围空间的外形轮廓,即可进行三维成像或三维建模。若需构建更大空间的三维模型,可以采用多个所述探测装置100协同工作。
请同时参阅图3,本发明还提供一种探测方法,图3示出了本发明一实施方式中探测方法的流程示意图。所述探测方法应用于所述探测系统S1及所述探测装置100中。所述的探测方法包括:

进一步地,所述机身22上还设置有驱动件221,所述驱动件221用于装设所述探测装置100。在本实施方式中,所述驱动件221为旋转电机。所述驱动件221包括本体2211及安装部2213。具体在图示的实施例中,所述本体2211设置于所述机身22上,所述安装部2213设置于所述本体2211上,并能在所述控制装置24的驱动下,相对所述本体2211绕一第三轴线转动。所述安装部2213用于装设所述探测装置100。当所述探测装置100设置于所述安装部2213上时,所述第三轴线大致与所述第一轴线及所述第二轴线均垂直,即,所述第一轴线、所述第二轴线及所述第三轴线两两正交设置。
当所述无人机200利用所述探测装置100检测其周围的障碍物时,所述驱动件221可以驱动所述探测装置100绕所述第三轴线转动,使所述发射组件30能够向所述第三轴线方向的四周扫描并发射信号。同时,所述探测装置100的驱动器34可以驱动所述反射器36绕所述第一轴线或/及所述第二轴线转动,使所述发射组件30能够向所述无人机200四周扫描并发射信号。

另外,本发明的探测装置100,采用了微电子机械系统驱动器作为所述驱动器34驱动所述反射器36转动,由于微电子机械系统驱动器本身体积微小且精度高,使所述探测装置100在具有较高的探测精度的同时,整体体积较小,其布置的灵活性较高,且便于所述无人机200搭载或携带。
可以理解,所述驱动件221可以省略,而直接将所述探测装置100装设于所述机身22上即可。
