本实施例中,载体文件的格式可以是开源、公知的格式,例如ShapeFile(shp)格式、ISOXML(xml)格式等。
可以理解,载体文件可以包括多组或仅一组位置坐标数据,本申请的实施例对此不作限定。
可以理解,在生成载体文件前,操作人员或处理器10可以对需要保存在载体文件内的位置坐标数据进行筛选。一种实现方式中,操作人员可以通过操作操控面板或用户终端,手动选择需要生成的载体文件对应的位置坐标数据。另一种实现方式中,处理器10可以跟根据预设的数据共享规则,自动选择指定组别的位置坐标数据保存于载体文件中,预设的数据共享规则的规则文件可以存储在存储器20中。

步骤S22:根据载体文件的格式,选用对应的内容解析模块80(图9中示出)解析载体文件,获得多个位置坐标数据。
可以理解,不同品牌或型号的电子设备200或者产生的载体文件格式,或者不同形式产生的载体文件的格式可能不同。针对不同格式的载体文件,可以通过对应的内容解析模块80进行解析,从而获取原始的位置坐标数据。
可以理解,一个电子设备200获取载体文件时,无法对载体文件的来源进行确定。载体文件可以是其他的电子设备200执行导出方法后产生的,也可以是通过农机信息共享方法以外的其他办法产生的。例如,产生载体文件的其他办法可以是操作人员人为对位置坐标数据编辑后产生载体文件。又例如,产生载体文件的其他办法可以是部分具有点位记录及位置坐标数据距离功能,且未与电子设备200连接的农机100,根据预设格式产生载体文件。
一些实施例中,解析载体文件后,在获得多个位置坐标数据的同时,处理器10还可以获得与多个位置坐标数据对应的坐标系参数。处理器10可以根据坐标系参数建立坐标系,位置坐标数据所对应的坐标点可以标记在处理器10建立的坐标系内。
请参阅图3,一些实施例中,解析载体文件的方法可以包括以下步骤S31至S33。
步骤S31:根据载体文件的后缀名,确定载体文件的格式是否为可识别的格式;若确定载体文件的格式为可识别的格式,则进入步骤S32;若确定载体文件的格式为不可识别的格式,则进入步骤S33。
可以理解,不同格式的载体文件具有不同的后缀名。例如,ShapeFile格式的载体文件的后缀名可以是shp,ISOXML格式的载体文件的后缀名可以是xml。 通过识别后缀名,可以确定载体文件的格式。
可以理解,在不同品牌或型号的农机100或电子设备200上,处理器10可以解析及可以产生的载体文件的格式可能存在不同。因此,在解析载体文件前,需对载体文件的格式进行确定,并根据载体文件的格式确定当前电子设备200是否可以识别获取的载体文件。处理器10需调用不同的内容解析模块80解析不同格式的载体文件。
步骤S32:根据载体文件的格式,选用对应的内容解析模块80解析载体文件。
可以理解,载体文件的格式可以是开源、公知的格式,内容解析模块80也可以是开源、公知的。例如,载体文件的格式可以是ShapeFile格式,对应的内容解析模块80可以是在GDAL库的基础上进行二次开发产生的内容解析模块80,其中,GDAL库是一个用于栅格和矢量地理空间数据格式的开源的转换程序库。又例如,载体文件的格式可以是ISOXML格式,对应的内容解析模块80可以是在dom4j库和ISO11783协议的基础上产生的内容解析模块80,其中,dom4j库是一个用于ISOXML格式文件解析的开源的工具包。
可以理解,解析载体文件后,可以获得多个位置坐标数据,多个位置坐标数据可以为一组或多组位置坐标数据;一组位置坐标数据中,多个位置坐标数据依序排列。
步骤S33:输出提醒信息。
可以理解,当处理器10无法解析获取的载体文件时,处理器10可以输出提醒信息给操作人员,提醒操作人员对轨迹路线和工作范围进行重新设定,或提醒工作人员获取另外的载体文件。

可以理解,提醒装置可以是具有发出声音、发出亮光和/或显示影像等功能的电子装置。提醒装置可以是但不局限于液晶屏幕、警示灯、音响等。
请继续参阅图2,步骤S23:根据分类模型确定位置坐标数据的数据类型。
本实施例中,数据类型包括作业数据、轨迹数据和区域数据。作业数据对应于生成载体文件的电子设备200连接的农机100的实际行进轨迹路线。轨迹数据对应于生成载体文件的电子设备200连接的农机100的预设行进轨迹路线。区域数据对应于生成载体文件的电子设备200连接的农机100的预设工作范围。
可以理解,一组位置坐标数据可以对应一个数据类型的位置坐标数据。
可以理解,处理器10可以在多个位置坐标数据中,根据位置坐标数据部分特性,区别出多个位置坐标数据是否为同一组或不同组的位置坐标数据。例如,作业数据对应的一组位置坐标数据可以是A1(Xa1,Ya1)、A2(Xa2,Ya2)……An(Xan,Yan),轨迹数据对应的一组位置坐标数据可以是B1(Xb1,Yb1)、B2(Xb2,Yb2)……Bn(Xbn,Ybn),处理器10可以根据坐标点的标号首字母是A或B,对两组数据进行区别。
本实施例中,可以定义数据类型为作业数据的一组位置坐标数据为作业数据组,定义数据类型为轨迹数据的一组位置坐标数据为作业数据组,定义数据类型为区域数据的一组位置坐标数据为区域数据组。轨迹数据组对应坐标点的连线为一条直线线段或多条间隔设置的直线线段。区域数据组对应的坐标点的连线可以形成一封闭或接近封闭的区域。理想状态下,农机100可以区域数据组对应的区域内,沿轨迹数据组对应的直线线段行进并作业。但由于农机100作业的农田中地势不平、存在阻挡物等情况,农机100实际行进的轨迹可能偏离于轨迹数据组对应的直线线段;且当轨迹数据组对应有多条直线线段时,农机100需要在农田中经过多次转弯或掉头后,再沿多条直线线段行进并作业。因此作业数据组对应的坐标点的连线可能为多段折线,且作业数据组与轨迹数据组数据及数据数量可以存在差异。
请参阅图4,一些实施例中,确定位置坐标数据的数据类型的方法可以包括以下步骤S41、S42:
步骤S41:根据至少一组位置坐标数据计算至少一组特征数据。
可以理解,一组位置坐标数据包括多个依序排列的位置坐标数据。处理器10对一组位置坐标数据进行指定计算后,可以获得一组对应的特征数据。
可以理解,一组位置坐标数据对应于一组坐标点,一组坐标点包括多个依序排列的坐标点。一组位置坐标数据、一组坐标点与一组特征数据可以一一对应。
一些实施例中,特征数据可以包括坐标点个数、极值点个数、轨迹长度、端点距离、面积、掉头次数、闭合参数、开口参数和交点个数。
坐标点个数对应于一组坐标点的数量。处理器10通过解析载体文件获得多个位置坐标数据,并对多个位置坐标数据进行分组后,可以确定一组位置坐标数据对应的坐标点的数量。
极值点个数对应于一组所述坐标点中,坐标点连接形成轨迹的延伸方向,从远离坐标起点的方向转变至靠近坐标起点的方向,及从靠近坐标起点的方向转变至远离坐标终点的方向的次数。
可以理解,极值点个数可以对应于农机100行进时,农机100折返并沿靠近或远离农机100起点的方向移动的次数。
可以理解,极值点个数的计算方法可以包括:先计算一组坐标点中n+1个坐标点与坐标起点的欧式距离,得到距离数据【d0,d1,……,dn】。再对n+1个距离数据进行一阶差分,计算相邻距离di和di+1的距离差Δi,得到距离差数据【Δ0,Δ1,……,Δn-1】。最后在n个距离差数据中,根据相邻的距离差正负符号是否相反来确定是否存在极值点。当确定相邻的距离差正负符号相反时,可以确定存在一个极值点。所有满足Δi*Δi+1<0的距离差的个数之和,就是极值点的个数。
本实施例中,轨迹长度可以对应于一组坐标点依次连线产生的折线段的长度。处理器10可以将多个坐标点【P0,P1,……,Pn】按顺序连接,并计算得到的这线段的总长度,计算结果即为轨迹长度。
端点距离对应于一组坐标点中坐标起点P0和坐标终点Pn之间的距离。
面积对应于一组所述坐标点依次连线形成的封闭多边形的面积。处理器10可以将多个坐标点【P0,P1,……,Pn】按顺序连接,其中若P0和Pn不重合,则再将P0和Pn连接,得到一个封闭多边形。处理器10可以计算多边形的面积。
掉头次数对应于一组坐标点中,一坐标点与坐标起点的连线在坐标系中的角度,及相邻的另一坐标点与坐标起点的连线在坐标系中的角度之间的差值大于180度的次数。处理器10可以依次对多个坐标点与坐标起点的连线的角度进行计算,得出多个角度值后,再对计算相邻角度值之间的差值。当处理器10计算确定两个相邻角度之间的差值大于180度时,处理器10可以进行一次计数。当对所有相邻角度之间差值计算完成,且对所有差值进行是否大于180度的判 定后,处理器10计数的最终结果即为掉头次数。
闭合参数对应于一组坐标点中,坐标起点与坐标终点的间距是否小于第一阈值的判断结果。处理器10可以计算坐标起点与坐标终点之间的距离,再将计算结果与预设的第一阈值进行对比。若确定计算结果大于或等于第一阈值,则确定该组坐标点的连线并非闭合,确定闭合参数为0。若确定结果计算结果小于第一阈值,则确定该组坐标点的连线闭合,确定闭合参数为1。
开口参数对应于一组坐标点中,坐标起点与坐标终点的间距是否大于第二阈值。处理器10可以计算坐标起点与坐标终点之间的距离,再将计算结果与预设的第二阈值进行对比。若确定计算结果大于第二阈值,则确定该组坐标点的连线开口,确定开口参数为1。若确定结果计算结果小于或等于第二阈值,则确定该组坐标点的连线并非开口,确定开口参数为0。
可以理解,第一阈值小于第二阈值。第一阈值和第二阈值可以是农机信息共享方法运行前,由操作人员预设的常数阈值。
本实施例中,交点个数对应于一组坐标点中,各坐标点依序连接形成的折线La,及坐标起点与坐标终点连接形成的线段Lb之间交点的个数。可以理解,处理器10可以在坐标系中获取折线La与线段Lb的交点,并计算交点个数。
一些实施例中,处理器10在计算特征数据的同时,可以根据特征数据确定获取的位置坐标数据是否为当前电子设备200可用的位置坐标数据。
示例的,部分电子设备200仅可处理并运用对应的坐标点的连线闭合的位置坐标数据,处理器10可以根据闭合参数是否为1,确定位置坐标数据是否为当前农机100的电子设备200可用的位置坐标数据。
示例的,部分电子设备200仅可处理并运用对应的坐标点的连线开口的位置坐标数据,处理器10可以根据开口参数是否为1,确定位置坐标数据是否为当前农机100的电子设备200可用的位置坐标数据。
一些实施例中,处理器10在执行导出方法时,处理器10生成并输出载体文件前,可以进行一次特征数据的计算,并根据特征数据确定处理器10选取的位置坐标数据是否为可被其他农机100的电子设备200运用的位置坐标数据。特征数据的计算过程可参照上文所述实施例,在此不再赘述。
可以理解,确定处理器10选取的位置坐标数据是否可被其他农机100的电子设备200运用的具体方法,可以等同于上文所述的确定获取的位置坐标数据 是否为当前农机100的电子设备200可用位置坐标数据的方法,在此不再赘述。
步骤S42:根据机器学习方法产生的分类模型,确定至少一组特征数据对应的数据类型。
可以理解,将与一组位置坐标数据对应的一组特征数据输入给分类模型后,分类模型可以根据各特征数据的数值,预测该组位置坐标数据对应的数据类型。
可以理解,由于多个农机100、电子设备200的品牌、型号可能不同,因此产生的载体文件内容可能存在不同。部分载体文件的内容中包括位置坐标数据的数据类型,部分载体文件的内容中不包括位置坐标数据的数据类型。由于获取载体文件的电子设备200在对多个位置坐标数据进行分组后,需确定各组位置坐标数据对应的数据类型后再对各组位置坐标数据进行运用。因此,当获取的载体文件的内容中不包括位置坐标数据的数据类型时,处理器10可以通过分类模型确定各组位置坐标数据的数据类型。
可以理解,当获取的载体文件中包括位置坐标数据的数据类型时,处理器10对载体文件解析后即可获得数据类型。此时,处理器10可以不执行步骤S23并直接执行下一步骤。
可以理解,机器学习可以在经验学习中改善分类模型所涉及的具体算法的性能,从而提高分类模型对数据类型确定的准确性。
请参阅图5,一些实施例中,训练分类模型的方法可以包括以下步骤S51至S55:
步骤S51:获取多组位置坐标数据。
步骤S52:根据多组位置坐标数据计算多组特征数据。
可以理解,特征数据的计算方法及特征数据的类型可以参阅上述实施例,在此不在赘述。
步骤S53:获取多组位置坐标数据及多组特征数据对应的数据类型。
可以理解,对分类模型进行训练的时候,需选用已知对应数据类型的位置坐标数据。在通过多组位置坐标数据训练分类模型时,应选用多组数据类型不同的位置坐标数据,以提高训练后的分类模型对数据类型确定的准确性。
步骤S54:输入多组特征数据及对应的数据类型给分类模型。
步骤S55:根据机器学习方法训练分类模型。
可以理解,多组数据类型及对应的数据类型为分类模型训练的素材。训练 分类模型时,通过机器学习的方式,处理器10可以根据多组正确对应的特征数据及数据类型,优化分类模型涉及的算法,从而提高分类模型的准确性。
可以理解,本申请的实施例中,对训练分类模型采用的具体的机器学习方式不作限定。例如,可以采用支持向量机SVM训练分类模型。
可以理解,训练分类模型的过程可以由处理器10执行,也可以由远端服务器或其他设备执行,本申请的实施例对此不作限定。
请继续参阅图2,步骤S24:提取作业数据组中形成直线轨迹的多个位置坐标数据,产生直线数据组。
可以理解,作业数据组对应的多个坐标点中,部分坐标点对应农机100行进时接近直线的轨迹,部分坐标点对应于农机100掉头或转弯时的轨迹。处理器10提取出与直线轨迹对应的坐标点及位置坐标数据后,可以根据产生直线数据组规划农机100后续在相似或相同的区域内作业时的行进路线。处理器10还可以根据产生直线数据组调整轨迹数据组中的位置坐标数据。
请参阅图6,一些实施例中,产生直线数据组的方法可以包括以下步骤S61至S66:
步骤S61:删除作业数据组中的差错数据。
本实施例中,差错数据可以包括噪声数据和杂波数据。
可以理解,在农机100行进过程中,由于其他设备的信号干扰或电子设备200数据记录产生的差错,可能将部分差错数据记录于作业数据组中。步骤S61执行可以实现对作业数据组的去噪和滤波,以消除可能影响操作人员或处理器10对农机100行进轨迹识别的无关数据。
可以理解,本申请的实施例对去噪和滤波的具体方法不作限定。例如,处理器10可以通过道格拉斯-普克算法对作业数据组去噪,可以通过卡尔曼滤波算法对作业数据组滤波。
步骤S62:计算剩余的多个位置坐标数据对应的多个坐标点中,各相邻坐标点的连线角度。
本实施例中,连线角度为相邻的坐标点连接形成的向量的反正切值对应的角度。例如,相邻两个坐标点的坐标分别为Pi(xi,yi)和Pj(xj,yj),计算向量(yj-yi,xj-xi)的反正切值后,可以根据计算的出的反正切值,得到对应的相邻坐标点的连线角度αi。
步骤S63:确定多个连线角度除以预设的角度阈值的多个计算结果。
可以理解,在步骤S62中可以计算获得n个连线角度【α1,α2,……,αn】。步骤S63中,需要对n个连线角度分别进行一次除以角度阈值θ的计算,得到多个计算结果【α1/θ,α2/θ,……,αn/θ】。
可以理解,角度阈值可以对应于农机100转弯或掉头时农机100的行进角度。角度阈值可以根据农机100所在农田的不同,或农机100、电子设备200的品牌、型号的不同而不同。
可以理解,角度阈值可以是在区间【90,180】中的一个角度值,例如,角度阈值可以是95。
步骤S64:将多个计算结果中,整数部分相同的计算结果对应的位置坐标数据分为相同子组别,整数部分不同的计算结果对应的位置坐标数据分为不同子组别。
可以理解,步骤S63中得出的多个计算结果分别与步骤S62中得出的多个连线角度一一对应,且各连接角度分别对应有一个位置坐标数据,因此各计算结果分别对应有一位置坐标数据。
可以理解,连线角度除以角度阈值的计算结果可能有余数或小数。一种实现方式中,仅提取整数部分用于对位置坐标数据分组即可。另一种实现方式中,可以对计算结果进行取整处理,即将计算结果调整为仅存在整数的结果后,再根据计算结果对位置坐标数据进行分组。
可以理解,本申请的实施例中对计算结果取整的方法不作限定。例如,可以根据四舍五入的规则,调整多个计算结果。又例如,可以直接对存在余数或小数的计算结果的整数部分加1后,再消除余数或小数,形成新的计算结果。
步骤S65:确定包含位置坐标数据最多的子组别为直线数据组。
可以理解,在农机100行进及作业过程中,农机100大部分时间及路程内是沿接近于直线的轨迹运行的,因此可以将包含位置坐标数据最多的子组别确定为直线数据组。
可以理解,可以定义与直线数据组对应的多个坐标点为直线坐标点组。
步骤S66:删除直线数据组中,农机100无法到达的坐标点对应的位置坐标数据。
可以理解,由于农机100的品牌、型号不同,农机100的转弯半径可能不 同。因此,直线坐标组中部分的坐标点可能是原农机100可以到达,而当前农机100无法到达的。为了避免在规划当前农机100行进路线时,将当前农机100由于转弯半径限制而无法到达的坐标点规划在行进路线中,需要删除直线数据组中,农机100无法到达的坐标点对应的位置坐标数据,并形成新的直线数据组。
请参阅图7,一些实施例中,删除农机100无法到达的坐标点对应的位置坐标数据的具体方法可以包括以下步骤S71至S74:
步骤S71:在直线坐标点组中,按顺序计算三个相邻坐标点的拟合圆的拟合半径。
请一并参阅图8A,可以理解,直线坐标点组中,多个坐标点依序排列。例如,如图8A所示,直线坐标点组中的多个坐标点的标号可以是【P0,P1,……,P8,P11,P12,……,P18,P21,P22,……P28】,处理器10通过识别坐标点标号的数字部分,即可确定坐标点的排序。
可以理解,直线坐标点组中,多个坐标点依序连接可以形成一条或多条折线。当处理器10识别相邻两个坐标点标号的数字部分为不连续的数值时,可以在两个坐标点之间的连接线段删除,从而使多个坐标点依序连接形成的一条折线形成两条折线。当处理器10识别相邻两个坐标点标号的数字部分为不连续的数值时,两个坐标点可以处于不同的接近于直线的行进轨迹上。
可以理解,直线数据组中的位置坐标数据可以是直线坐标组中各坐标点在坐标系中的坐标,处理器10可以根据坐标点对应的位置坐标数据确定坐标点的坐标后,再对三个坐标点的拟合圆的拟合半径进行计算。
可以理解,三个相邻坐标点位于三个相邻坐标点的拟合圆的圆弧上。
步骤S72:确定拟合半径是否小于农机100的转弯半径,若拟合半径小于农机100的转弯半径,则进入步骤S73;若拟合半径大于或等于农机100的转弯半径,则进入步骤S74。
可以理解,电子设备200可以获取连接的农机100的内部参数,内部参数包括转弯半径。本申请实施例中对电子设备200获取农机100的转弯半径的途径不作限定。
步骤S73:删除三个相邻的坐标点中,排序末位的坐标点对应的位置坐标数据,并依照多个坐标点的排序,选取下一个坐标点,与前序两个相邻的坐标点 重新进行拟合圆的形成及拟合半径的计算。
可以理解,当拟合圆的拟合半径小于农机100的转弯半径时,农机100无法到达三个坐标点中排序最末的坐标点对应的位置。删除了直线数据组中的一个位置坐标数据后,等同于删除直线坐标点组中的一个坐标点。因此,此时位于删除的坐标点后的下一个坐标点,与前序的两个相邻的坐标点形成三个相邻的坐标点。
请一并参阅图8B,可以理解,删除一个坐标点后,直线坐标点组中多个坐标点形成的连线出现一个隔断空间,从而将一条折线拆分为两条折线。例如,如图8B所示,当坐标点P3、P4及P5所在的拟合圆的拟合半径小于农机100的转弯半径时,在直线坐标点组中删除坐标点P5,并在直线数据组中删除与坐标点P5对应的位置坐标数据。坐标点P4与坐标点P6之间形成隔断空间,原先由坐标点P1至坐标点P8连接形成的一段折线,拆分为由P1、P2、P3和P4依序连接形成的第一折线L1,及由P6、P7和P8依序连接形成的第二折线L2。
可以理解,在农机100行进的过程中,操作人员需要手动驾驶农机100通过对于两条折线所对应的轨迹路线之间的隔断空间。例如,农机100按如图8B所示的多个坐标点在农田中行进时,电子设备200可以辅助农机100自动行驶通过第一折线L1及第二折线L2对应的路程,驾驶人员需要手动驾驶农机100通过坐标点P4与坐标点P6之间的隔断空间对应的路程。
可以理解,基于GIS建立的大地坐标系较普通的二维坐标系更为复杂,本申请中的图8A和图8B中的坐标系仅作为一种示意,并不等同于实际各坐标点所在的实际的坐标系。
步骤S74:选取三个相邻坐标点中排序位于第二和第三的两个坐标点,并依照多个坐标点的排序,选取下一个坐标点,与前序两个相邻的坐标点重新进行拟合圆的形成及拟合半径的计算。
可以理解,若确定拟合半径大于或等于转弯半径,则可以确定三个坐标点对应的位置均为农机100可以到达的位置,可以保留三个坐标点对应的位置坐标数据,并依序选取下一个坐标点进行拟合半径的计算。
可以理解,步骤S73和步骤S74结束后,均依序选取下一坐标点并返回步骤S71,重新进行一次拟合半径的计算和阈值对比。直线坐标点组的所有坐标点均进行过一次拟合半径的计算和阈值对比后,步骤S71至步骤S74停止执行。 处理器10获得最终调整后的直线数据组。处理器10可以根据直线数据组规划农机100在农田中作业时的行进路线。
