具体实施方式
本发明实施例提供了一种ADAS摄像头的标定方法、装置、存储介质及终端设备,用于解决目前ADAS摄像头的标定方法成本高、操作复杂的问题。
为使得本发明的发明目的、特征、优点能够更加的明显和易懂,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描 述,显然,下面所描述的实施例仅仅是本发明一部分实施例,而非全部的实施例。基于本发明中的实施例,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它实施例,都属于本发明保护的范围。
请参阅图1,本发明实施例中一种ADAS摄像头的标定方法一个实施例包括:
101、测量车辆上目标摄像头的安装高度,所述车辆放置于平坦的地面上;
结合图2,车辆上安装有目标摄像头,即图2中A点的位置,A点距离地面的高度即为上述的安装高度,记为m。
其中,为了标定的准确性,要求车辆放置在平坦的地面上,可以预先采用工程测量方法测量地面的平整度,通过更换地面或者修补不平整的地方来保证地面是平坦的。
102、确定所述目标摄像头垂直于所述地面的第一位置;
上述的第一位置即图2中的C点位置,AC两点的连线垂直于地面。
进一步地,如图3所示,上述步骤102具体可以包括:
301、在所述目标摄像头前方的区域中放置垂直于所述地面的高度测量尺,所述高度测量尺的上端高于所述目标摄像头;
302、校准所述高度测量尺的水平方向和竖直方向;
303、测量所述目标摄像头与所述高度测量尺之间的第一距离;
304、从所述高度测量尺的下端位置向所述目标摄像头方向移动所述第一距离,确定出所述目标摄像头垂直于所述地面的第一位置。
结合图4,A点为目标摄像头的安装位置,C点为所述第一位置,BD为在目标摄像头前方的区域中放置的垂直于地面的高度测量尺。在放置高度测量尺时,可以在水平和竖直方向上各放一水准泡以校准BD的水平和竖直方向。记|AC|=|BD|=m(单位可以是米),通过测量容易得到距离|AB|=d(单位可以是米),则从高度测量尺的下端位置D点处向BA方向测量d距离即可得到C点位置,标记C点在地面上的位置,即确定出了该第一位置。
其中,在上述步骤301~304的测量过程中,放置高度测量尺时只需在目标摄像头稍前一点的位置放置即可,即放置高度测量尺后d的值较小更优,这样在测量d时,测量结果存在的误差会更小。
103、在所述目标摄像头前方的拍摄区域中放置标定板,所述标定板上设有刻度;
参照图2,在目标摄像头前方的拍摄区域中放置标定板,即图2中FH的位置上,标定板的下端点为F点,记距离|CF|=f,CF垂直于AC。优选地,|CD|<f<y,其中,y是指下述的标定距离,即图2中的|CK|。这可以使得标定板的放置距离可以很近,解决了车前空间有限而只能通过将车开到相对空旷地等方式再进行标定的麻烦,尤其是当需要批量标定且车前空间有限的情况下,能方便非常多。
其中,在放置标定板时,可以通过水准泡来调整标定板的水平与竖直方向,确保标定板的放置是垂直于地面的。
104、测量所述第一位置与所述标定板放置位置的距离,得到标定板放置距离;
在步骤104中,测量所述第一位置与所述标定板放置位置的距离,也就是测量图2中的f值,f为标定板放置距离。
105、在启动所述目标摄像头后,确定ADAS的显示屏中标定线落在标定板上的当前刻度;
106、读取当前所述标定线对应的标定距离;
对于上述步骤105~106,参照图2,K点为目标摄像头当前的标定线对应的标定距离所在的地面上的点,|CK|=y为所述标定距离,H点的位置即为ADAS的显示屏中标定线落在标定板上的当前位置,并可以直接通过标定板上设有的刻度读取出该当前位置的当前刻度的值,记该值为x1。
107、根据所述安装高度、所述标定板放置距离和所述标定距离确定所述标定线在所述标定板上的目标刻度;
可以理解的是,如图2所示,在得知安装高度m、标定板放置距离f和标定距离y的情况下,可以确定出所述标定线在所述标定板上的目标刻度,也即标定板上H点对应的刻度。
进一步地,所述上述步骤107可以包括:首先,根据所述安装高度、所述标定板放置距离和所述标定距离计算目标高度,所述目标高度是指所述标定线在所述标定板上的目标位置与所述地面的垂直距离;然后,确定所述标定板上与所述目标高度对应的刻度为目标刻度。
其中,具体可以将所述安装高度m、所述标定板放置距离f和所述标定距离y代入第一公式计算目标高度;
所述第一公式为:
Figure PCTCN2017119962-appb-000003
其中,x为所述目标高度,也即H点对应的刻度的值,或H点距离地面的高度值。
确定目标高度x之后,即根据x的值从标定板上确定出目标刻度的位置。
108、调节所述目标摄像头的拍摄角度,使得所述标定线从所述当前刻度移动至所述目标刻度。
一般情况下,未经过调节的目标摄像头通常需要进行标定,也即当前刻度与目标刻度不在同一个位置上。因此,可以调节所述目标摄像头的拍摄角度,使得所述标定线从所述当前刻度移动至所述目标刻度,即x1=x,这时候该目标摄像头完成标定。
进一步地,在调节所述目标摄像头的拍摄角度,使得所述标定线从所述当前刻度移动至所述目标刻度之后,该ADAS摄像头的标定方法还可以对标定后的目标摄像头进行验证,检验该目标摄像头标定是否准确,如图5所示,具体步骤包括:
501、确定用于验证的指定标定距离;
502、在所述目标摄像头的正前方且与所述第一位置相隔所述指定标定距离的地面上放置一杆状物,所述杆状物与所述正前方方向垂直;
503、在启动所述目标摄像头后,调节所述ADAS显示屏中的标定线,使得标定线对应的标定距离等于所述指定标定距离;
504、判断所述ADAS显示屏中的标定线是否与所述显示屏中显示的杆状物重合,若是,则执行步骤505,若否,则执行步骤506;
505、确定所述目标摄像头的标定结果准确;
506、确定所述目标摄像头的标定结果不准确。
对于上述步骤501~506,先指定一个用于验证的标定距离,即所述指定标定距离,并在启动所述目标摄像头后,根据该指定标定距离调节所述ADAS显示屏中的标定线,使得调节后的标定线的标定距离等于该指定标定距离。
在目标摄像头的正前方且与第一位置相隔所述指定标定距离的地面上放置一杆状物,参考图2,即在k点位置放置该杆状物。该杆状物与目标摄像头的正前方方向垂直。可以理解的是,ADAS显示屏中的标定线一般均是横线,因此与之对应的,该杆状物也是横向放置。
需要说明的是,由于是对标定后的目标摄像头进行验证,ADAS上的已设置后该目标摄像头的安装高度,即m值。在启动ADAS之后,通过判断显示屏中的标定线是否与所述显示屏中显示的杆状物重合,即可判断得知该目标摄像头标定是否准确。如果标定线与显示的杆状物重合,则可以认为所述目标摄像头的标定结果准确;反之,如果标定线与显示的杆状物不重合,则可以认为所述目标摄像头的标定结果不准确。
比如,在一个应用场景中,可以在距离K点4米处完成标定,即y=4,然后通过上述第一公式分别计算出y=3、y=5处对应位置放置好杆状物,并分别从ADAS显示屏上看y=3时该标定线是否与3米处的杆状物重合、y=5时该标定线是否与5米处的杆状物重合。
本实施例中,前面所说的ADAS摄像头的标定方法步骤为:首先,测量车辆上目标摄像头的安装高度,所述车辆放置于平坦的地面上;确定所述目标摄像头垂直于所述地面的第一位置;然后,在所述目标摄像头前方的拍摄区域中 放置标定板,所述标定板上设有刻度;接着,测量所述第一位置与所述标定板放置位置的距离,得到标定板放置距离;在启动所述目标摄像头后,确定ADAS的显示屏中标定线落在标定板上的当前刻度;读取当前所述标定线对应的标定距离;再之,根据所述安装高度、所述标定板放置距离和所述标定距离确定所述标定线在所述标定板上的目标刻度;最后,调节所述目标摄像头的拍摄角度,使得所述标定线从所述当前刻度移动至所述目标刻度,完成目标摄像头的标定。可见,本申请方案原理简单易懂,无需非常专业的技术原理或数理领域知识;成本非常低,不需要昂贵的高精度仪器;标定过程简单,利于方法的复制推广,可快速上手;适于近、远距离标定,标定位置灵活。
应理解,上述实施例中各步骤的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本发明实施例的实施过程构成任何限定。
