具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行 清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
为了解决上述技术问题,本申请实施例提供了一种PT坐标与GPS坐标的转换方法及球机,该方法可以应用于球机,或者也可以应用于与球机通信连接的其他电子设备,比如,手机、电脑,等等,具体不做限定。下面首先对本申请实施例提供的第一种PT坐标与GPS坐标的转换方法进行详细介绍,PT坐标与GPS坐标的转换方法也就是将PT坐标转换为GPS坐标的方法。
图1为本申请实施例提供的第一种PT坐标与GPS坐标的转换方法的流程示意图,包括:
S101:获取球机拍摄监控目标时的PT坐标,作为第一P坐标和第一T坐标。
球机坐标系通常为PTZ(Pan/Tilt/Zoom,云台左右/上下移动及镜头变倍、变焦控制)坐标系。图1所示实施例中的监控目标,即为需要确定GPS坐标的目标,也就是需要将球机拍摄该监控目标时的PT坐标转换为该监控目标的GPS坐标。为了方便描述,将球机拍摄监控目标时的P坐标称为第一P坐标,将球机拍摄监控目标时的T坐标称为第一T坐标。
一种实施方式中,在球机具有检测自身的PT坐标功能时,可以直接读取球机拍摄监控目标时的PT坐标,作为第一P坐标和第一T坐标。
另一种实施方式中,可以获取监控目标在球机拍摄图像中的图像坐标;根据所述图像坐标、以及所述球机拍摄所述监控目标时的视场角,确定所述球机正对所述监控目标时的PT坐标,作为第一P坐标和第一T坐标。
本实施方式中,可以先读取球机拍摄监控目标时的PT坐标,然后根据监控目标在球机拍摄图像中的图像坐标、以及球机拍摄监控目标时的视场角,将读取到的PT坐标转换为球机正对所述监控目标时的PT坐标,作为第一P坐标和第一T坐标。
应用本申请实施例将球机的PT坐标转换为监控目标的GPS坐标时,若球机正对监控目标,则得到的监控目标的GPS坐标更准确。而应用本实施方式得到的第一P坐标和第一T坐标为球机正对监控目标时的PT坐标,因此, 利用本实施方式,可以得到更准确的GPS坐标。
具体来说,假设监控目标在球机拍摄图像中的图像坐标为(X,Y),则可以利用以下算式转换得到第一P坐标和第一T坐标:
Pan_tar=Pan_cur+arctan((2*X/L 1-1)*tan(θ 1/2));
Tilt_tar=Tilt_cur+arctan((2*Y/L 2-1)*tan(θ 2/2));
其中,Pan_tar表示第一P坐标,Tilt_tar表示第一T坐标,Pan_cur表示当前球机在PT坐标系中的水平方向角度,也就是上述读取到的P坐标,Tilt_cur表示当前球机在PT坐标系中的垂直方向角度,也就是上述读取到的T坐标,(Pan_cur,Tilt_cur)为当前图像中心位置的坐标,L 1表示图像横向的总像素数,L 2表示图像纵向的总像素数,θ 1表示为当前图像所对应的水平视场角,θ 2表示为当前图像所对应的垂直视场角;XY坐标系以图像左上角为原点,以像素为单位。
S102:基于第一P坐标,确定监控目标与指定方向的水平夹角。
举例来说,该指定方向可以为正北方向,也可以为正南方向,也可以为正东方向,也可以为正西方向,具体不做限定。
作为一种实施方式,步骤S102可以包括:通过所述球机的电子罗盘,获取球机指向指定方向时的球机P坐标,作为第二P坐标;计算所述第一P坐标与所述第二P坐标之差,作为所述监控目标与所述指定方向的水平夹角。
通过球机的电子罗盘,可以获取球机指向正北、正南、正东、正西等方向时的球机P坐标,为了区分描述,将球机指向指定方向时的球机P坐标称为第二P坐标。第一P坐标与第二P坐标之差,即为监控目标与指定方向的水平夹角。
S103:基于第一T坐标以及球机的高度,计算监控目标与球机的水平距离。
步骤S102与步骤S103的执行顺序不做限定。
一种实施方式中,可以计算第一T坐标的正切值与所述球机的高度的乘积,作为监控目标与所述球机的水平距离。参考图2可知,tanT*h=L,h表示球机的高度,L表示监控目标与球机的水平距离。水平距离也就是假设球机与监控目标高度相同的情况下,球机与监控目标的距离。
S104:根据该水平夹角和该水平距离,通过三角函数计算监控目标与球机的经线方向距离和纬线方向距离。
一种实施方式中,步骤S102中的指定方向为正北,这种情况下,步骤S104可以包括:计算所述水平夹角的正弦值与所述水平距离的乘积,作为所述监控目标与所述球机的经线方向距离;计算所述水平夹角的余弦值与所述水平距离的乘积,作为所述监控目标与所述球机的纬线方向距离。
参考图3,图3为球机的俯视图,图3中未体现球机的高度,由图3可知,L*sinθ=L lon,L*cosθ=L lat,L表示步骤S103中计算得到的水平距离,θ表示步骤S102中得到的监控目标与正北方向的水平夹角,L lon表示监控目标与球机的经线方向距离,L lat表示监控目标与球机的纬线方向距离。
或者,步骤S102中的指定方向为正东,这种情况下,步骤S104可以包括:计算所述水平夹角的余弦值与所述水平距离的乘积,作为所述监控目标与所述球机的经线方向距离;计算所述水平夹角的正弦值与所述水平距离的乘积,作为所述监控目标与所述球机的纬线方向距离。
这种情况下,步骤S102中得到的监控目标与正东方向的水平夹角为图3中的α,L*sinα=L lon,L*cosα=L lat
或者,步骤S102中的指定方向可以为正西或者正南,具体计算过程类似,不再赘述。
S105:基于球机的经纬度以及该经线方向距离和纬线方向距离,计算监控目标的GPS坐标。
球机通常具有GPS定位装置,可以基于该GPS定位装置得到球机的GPS坐标,GPS坐标中包括经纬度,这样,得到了球机的经纬度以及球机与监控目标的经线方向距离和纬线方向距离,便可以计算得到监控目标的经纬度,也就得到了监控目标的GPS坐标。
本申请图1所示实施例中,获取球机拍摄监控目标时的PT坐标;基于该P坐标,确定监控目标与指定方向的水平夹角;基于该T坐标以及球机的高度,计算监控目标与球机的水平距离;根据水平夹角和水平距离,通过三角函数计算监控目标与球机的经线方向距离和纬线方向距离;基于球机的经纬度以及该经线方向距离和纬线方向距离,计算监控目标的GPS坐标。可见, 本方案实现了将球机的PT坐标转换为GPS坐标,实现了针对球机的坐标转换。
图4为本申请实施例提供的第二种PT坐标与GPS坐标的转换方法的流程示意图,PT坐标与GPS坐标的转换方法也就是将GPS坐标转换为PT坐标的方法,包括:
S401:根据监控目标的GPS坐标、以及拍摄监控目标的球机的GPS坐标,计算球机与监控目标的经线方向距离和纬线方向距离。
GPS坐标包括经纬度,监控目标与球机的经度差即为计算得到的经线方向距离,监控目标与球机的纬度差即为计算得到的纬线方向距离。
S402:根据该经线方向距离和纬线方向距离,计算监控目标与球机的水平距离。
水平距离也就是假设球机与监控目标高度相同的情况下,球机与监控目标的距离。参考图3,一种情况下,可以认为地面是平面,利用下式计算监控目标与球机的水平距离:
Figure PCTCN2019119269-appb-000001
或者,也可以采用Haversine(半正矢)函数计算监控目标与球机的水平距离,参见下式:
Figure PCTCN2019119269-appb-000002
上式中,Aw表示监控目标的纬度,Aj表示监控目标的经度,Bw表示球机的纬度,Bj表示球机的经度,L表示监控目标与球机的水平距离,R表示球机所在位置的地球半径。
或者,也可以认为地面为球面,利用球面正余弦公式计算监控目标与球机的水平距离,也就是球面距离。计算监控目标与球机的水平距离的方式有多种,不再一一列举。
S403:根据该经线方向距离和纬线方向距离,通过三角函数计算监控目标与指定方向的水平夹角。
举例来说,如果指定方向为正北方向,则步骤S403可以包括:计算所述经线方向距离与所述纬线方向距离的比值,作为所述水平夹角的正切值;通过所述水平夹角的正切值,求解所述水平夹角。参考图3可知,tanθ=经线方向距离/纬线方向距离,θ即为监控目标与正北方向的水平夹角。
或者,该指定方向也可以为正东方向,这种情况下,步骤S403可以包括:计算所述纬线方向距离与所述经线方向距离的比值,作为所述水平夹角的正切值;通过所述正切值,求解所述水平夹角。参考图3可知,tanα=纬线方向距离/经线方向距离,α即为即为监控目标与正东方向的水平夹角。
或者,该指定方向也可以为正西或者正南,具体计算过程类似,不再赘述。
S404:根据该水平夹角,确定球机的P坐标。
球机的P坐标可以理解为球机在水平方向的角度,已知球机与指定方向的水平夹角,即可确定球机在水平方向的角度,也就得到了球机的P坐标。其中,指定方向可以如正北等方向。
S405:根据该水平距离及球机的高度,计算球机的T坐标。
步骤S405可以在步骤S402之后执行,步骤S402与步骤S403-步骤S404的执行顺序不做限定。
作为一种实施方式,可以计算所述水平距离与所述球机的高度的比值,作为所述球机的T坐标的正切值;通过所述球机的T坐标的正切值,求解所述球机的T坐标。
参考图2可知,tanT*h=L,h表示球机的高度,L表示监控目标与球机的水平距离,T表示球机的T坐标。可以根据该算式计算得到球机的T坐标。
基于以上步骤,便可以将监控目标的GPS坐标转换为球机的PT坐标。
作为一种实施方式,若确定的所述球机的P坐标存在水平误差,则通过调节所述球机的电子罗盘,减少所述水平误差。
作为一种实施方式,若计算得到的所述球机的T坐标存在垂直误差,则通过调节所述球机的高度值,减少所述垂直误差。
上述实施例中的球机高度可以预先配置在球机中,该预先配置的高度值可能是存在误差的,可以通过调节配置在球机中的高度值,减少所述垂直误 差。
发明人经实验发现,通过调节球机的电子罗盘,可以减少坐标转换的水平误差,通过调节球机的高度值,可以减少坐标转换的垂直误差。
一些相关方案中,对坐标转换的误差进行整体矫正,但是不同方向上的误差矫正会相互影响。而本申请所提供的这两种实施方式中,可以通过调节不同的参数实现对不同方向的误差分别进行矫正,减少了这种相互影响,提高了误差矫正的准确度。
应用本申请图4所示实施例,将监控目标的GPS坐标转换为球机的PT坐标,实现了针对球机的坐标转换。
本申请实施例还提供了一种球机,如图5所示,包括图像采集器501、处理器502和存储器503;
图像采集器501,用于采集图像,并将所采集的图像作为待处理图像;
存储器503,用于存放计算机程序;
处理器502,用于执行存储器上所存放的程序时,实现上述任一种PT坐标与GPS坐标的转换方法。
上述图像采集器可以包括镜头、图像传感器等各种组件,具体不做限定。
上述存储器可以包括随机存取存储器(Random Access Memory,RAM),也可以包括非易失性存储器(Non-Volatile Memory,NVM),例如至少一个磁盘存储器。一种实施例,存储器还可以是至少一个位于远离前述处理器的存储装置。
上述的处理器可以是通用处理器,包括中央处理器(Central Processing Unit,CPU)、网络处理器(Network Processor,NP)等;还可以是数字信号处理器(Digital Signal Processing,DSP)、专用集成电路(Application Specific Integrated Circuit,ASIC)、现场可编程门阵列(Field-Programmable Gate Array,FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件。
