具体实施方式
下面详细描述本申请的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本申请,而不能理解为对本申请的限制。
下面参照附图描述根据本申请实施例提出的探测装置探测角度的调整方法、探测装置探测角度的调整装置、车辆、电子设备和计算机可读存储介质,首先将参照附图描述根据本申请实施例提出的探测装置探测角度的调整方法。
图1是本申请实施例的探测装置探测角度的调整方法的流程图。该实施例中,探测装置可为毫米波雷达、超声波雷达等,探测角度为探测装置所能探测到的角度。
如图1所示,该探测装置探测角度的调整方法包括以下步骤:
S1,获取车辆当前行驶的前方道路的第一弯曲信息。
在本申请的一个实施例中,为了能够获取车辆当前行驶的前方道路的第一弯曲信息,可以在车辆行驶过程中,通过车辆前方的图像采集装置(如摄像头)对车辆当前所行驶的前方道路进行图像采集,得到前方道路的路面图像,然后对路面图像进行识别,识别出前方道路为弯道时,根据路面图像获取车辆前方道路的第一弯曲信息,其中,第一弯曲信息可以为弯道的弯曲值,弯道的弯曲值表示道路的弯曲程度。由此,在到达弯道转弯 前就可以提前了解前方道路是否为弯道以及前面道路的弯曲程度,便于驾驶员为提前了解弯道上的道路情况做准备,用于指引驾驶员弯道处的驾驶行为,实现了对弯道的提前预测。
可选地,车辆上都安装有电子地图,电子地图上会存储有导航信息,导航信息会标注电子地图上每个区域或者路段的情况。本申请实施例中,可以基于车辆上的GPS(Global Positioning System,全球定位系统)得知车辆的当前位置,并根据导航信息得到车辆的当前位置前方道路的道路参数信息,以便根据道路参数信息判断前方道路是否为弯道,并在前方道路为弯道时,从道路参数信息中提取前方道路的第一弯曲信息,有效提高获取第一弯曲信息的准确性。
S2,根据第一弯曲信息,获取探测装置的调整角度。
当根据导航信息或者采集到的图像,识别出前方道路为弯道时,在弯道上如果继续保持探测装置之前的角度,可能会导致探测装置的探测区域,无法完全覆盖前方道路,容易出现探测盲区,本申请实施例中,在获取到前方道路的第一弯曲信息后,为了能够使得探测装置的探测范围能够与前方道路的弯曲程度匹配,以消除探测盲区,可以根据第一弯曲信息计算出探测装置的调整角度。
可选地,可以设置有前车道路的弯曲信息与探测装置的调整角度之间的映射关系,在获取到第一弯曲信息后,可以查询该映射关系,得到探测装置的调整角度。一般情况下,可以一个弯曲范围对应一个调整角度,可以先确定出第一弯曲信息所在的弯曲范围,然后根据该弯曲范围确定探测装置的调整角度。
可选地,设置有调整角度的计算公式,在获取到第一弯曲信息后,将该第一弯曲信息,输入到计算公式中,通过该计算公式输出一个探测装置的调整角度,通过计算公式计算的方式,能够得到一个精确的调整角度,使得探测装置的调整更加准确。
S3,根据调整角度,控制探测装置进行探测角度调整。
具体地,可以根据道路上的曲线变化情况,计算需要调节的角度值,通过控制器局域网络发给探测装置调节机构,以控制探测装置进行探测角度调整。
根据本申请实施例的探测装置探测角度的调整方法,可以获取车辆当前行驶的前方道路的第一弯曲信息,并根据第一弯曲信息,获取探测装置的调整角度,从而根据调整角度,控制探测装置进行探测角度调整,有效地增大探测装置的探测区域,减少探测装置的探测盲区,有利于对车前道路目标的识别,降低目标丢失的概率,提升驾驶的安全性,提升用户使用体验。
在本申请的一个实施例中,根据路面图像识别出前方道路为弯道时,获取前方道路的第一弯曲信息的过程,如图2所示,具体包括以下步骤:
S21,从路面图像中识别前方道路上的路面标志物。
实际生活中,道路旁都会有路面标志物,可以通过获取实际道路的影像序列数据进行识别前方道路上的路面标志物,如路面上的道路线、马路牙或路灯等道路识别信息,并对每一张影像进行路面标志物的检测识别,一般情况下,在道路上的弯道处都会在设置有弯道的路面标志物,因此,可以通过车辆上的图像采集装置获取车辆当前所行驶道路的路面图像,从路面图像中识别前方道路上的路面标志物。
S22,基于路面标志物,提取路面标志物所在像素点形成的连线,并获取连线的第二弯曲信息。
可以理解的是,可以根据路面标志物提取路面标志物的所在像素点形成的连线,如果路面标志物的所在像素点形成连线为直线,则代表不是弯道,如果路面标志物的所在像素点形成连线为曲线,则获取该曲线在路面图像中的位置信息,根据位置信息获取路面标志物的所在像素点形成连线的弯曲程度,即路面标志物的所在像素点形成连线的第二弯曲信息,其中,第二弯曲信息可以为路面标志物所在的像素点形成连线形成的弯曲值。
S23,根据第二弯曲信息,得到前方道路的第一弯曲信息。
一般情况下,路面标志物就是沿着道路进行布设的,路面标志物的弯曲程度往往反映出道路的弯曲程度,因此在获取到路面标志物的所在连线的第二弯曲信息后,就可以将该第二弯曲信息,作为前方道路的第一弯曲信息。具体地,通过第二弯曲信息的获取,根据预设的映射函数或者映射列表,可以得到与第二弯曲信息对应的第一弯曲信息,基于图像识别的方式来实时了解路面的情况,可以有效提高第一弯曲信息的精确性。
在本申请的一个实施例中,如图3所示,上述的前方道路的第一弯曲信息获取方法,还包括以下步骤:
S31,如果从路面图像中未识别到路面标志物,获取车辆当前的方向盘的转角信息。
具体地,有些弯道处可能不存在路面标志物,或者是由于时间较久路面标志物已经不清晰,则无法从路面图像中识别到路面标志物,因此,可以获取车辆当前的方向盘的转角信息,以通过转角信息来识别前方是否为弯道,通过多个方面进行识别,有效保证识别的准确性,其中,转角信息包含转向信息和角度信息。
作为一种的可能实现方式,方向盘的转角信息可以通过判断是否获取到导航系统发送的转角提示信息进行确定,其中,导航系统发送的转角提示信息可以是导航系统发出的语音提示信息,也可以是导航系统发出的路线提示信息等。
作为另一种可能的实现方式,方向盘的转角信息可以通过判断车辆的方向盘处于转向状态的持续时长超出预设时长来确定,并在超出预设时长时,触发确定前方道路的第一弯曲信息。也就是说,当通过方向盘转角传感器检测到方向盘存在逆时针转动操作且方向盘处于转向状态的持续时长超出预设时长t时,则生成车辆转角信息;同理可知,当通过方 向盘转角传感器检测到方向盘存在顺时针转动操作且方向盘处于转向状态的持续时长超出预设时长t时,则生成车辆转角信息。
需要说明的是,上述两种获取转角信息方式仅是示例性的,不作为对本申请的具体限制,当然本领域的技术人员还可以通过其他技术手段获取方向盘转角信息,在此不对其进行详细说明。
S32,根据转角信息,确定前方道路的第一弯曲信息。
一般情况下,车辆在行驶过程中,需要根据道路弯曲的程度进行转向,因此,在获取到转角信息后,就可以确定出前方道路的第一弯曲信息。
根据本申请实施例的探测装置探测角度的调整方法,可以在未从路面图像中未识别到路面标志物时,获取车辆当前的方向盘的转角信息,根据转角信息,确定前方道路的第一弯曲信息,从而有效地增大探测装置的探测区域,减少前毫米波雷达的探测盲区,有利于对车前道路目标的识别,降低目标丢失的概率,提升驾驶的安全性,提升用户使用体验。
下面结合图4、图5详细阐述本申请实施例的探测装置探测角度的调整方法。
如图4所示,本申请实施例的探测装置探测角度的调整方法涉及到的探测装置调节机构包括:调节杆1、雷达安装支架2、雷达3(探测装置可以为毫米波雷达)、第一驱动马达4和第二驱动马达5。其中,车前毫米波雷达调节机构分别通过第一驱动马达4和第二驱动马达5驱动调节杆1的运动,即调节毫米波雷达的水平角度和垂直角度,以达到调节前毫米波雷达发射面角度的作用,第一驱动马达4和调节杆1之间可为刚性连接,第二驱动马达5和调节杆1之间也可为刚性连接,调节杆,且第一驱动马达4和第二驱动马达5可以自带有马达运动圈数的计算,可以通过马达运动圈数结合传动比计算调节角度的反馈及零点位置的校正功能。
在本申请的一个实施例中,如图5所示,根据调整角度,控制探测装置进行探测角度调整,包括以下步骤:
S501,根据调整角度,获取用于驱动第一驱动马达和第二驱动马达的驱动马达的马达转动圈数。
具体地,探测装置的驱动马达可以包括第一驱动马达和第二驱动马达,第一驱动马达可以用于水平方向上调节探测装置,第二驱动马达可以垂直方向上调节探测装置。
S502,控制第一驱动马达和第二驱动马达分别按照各自对应的马达转动圈数进行转动,以带动探测装置分别在水平方向和垂直方向上发生与马达转动圈数对应的位移量。
具体地,驱动探测装置的驱动马达的马达转动圈数可以根据调整角度得到,从而根据驱动马达的马达转动圈数按序控制第一驱动马达水平方向上发生与马达转动圈数对应的位移量,按序控制第二驱动马达垂直方向上发生与马达转动圈数对应的位移量,通过第一驱 动马达和第二驱动马达根据调整角度来调节探测装置的转动角度,有效提高调节的准确性。
在本申请的一个实施例中,如图6所示,在根据调整角度,控制探测装置进行探测角度调整之后,还包括以下步骤:
S601,获取车辆的方向盘的转角信息。
S602,判断转角信息对应的探测装置的探测角度与调整后的探测装置的探测角度是否匹配。
具体地,为了保证探测装置进行探测角度调整的准确性,在初次调整之后,可以再次获取车辆的方向盘的转角信息,然后根据该转角信息,获取到与该转角信息对应的探测装置的探测角度。
进一步地,判断转角信息对应的探测装置的探测角度与调整后的探测装置的探测角度是否匹配,也就是说,如果在控制探测装置进行探测角度调整之后,转角信息对应的探测装置的探测角度与调整后的探测装置的探测角度相匹配,则说明调整准确。如果在控制探测装置进行探测角度调整之后,转角信息对应的探测装置的探测角度与调整后的探测装置的探测角度不匹配,则说明调整不够准确,需要对探测装置的探测角度进行修正,以使转角信息对应的探测装置的探测角度与调整后的探测装置的探测角度相匹配,以便于提高探测装置的探测范围,有效保证探测装置的探测角度的准确性。
S603,如果两个探测角度不匹配,则利用转角信息对应的探测装置的探测角度对调整后的探测装置的探测角度进行更新,实现对探测装置的探测角度实时调节。
下面结合图7、图8详细阐述本申请实施例的探测装置探测角度的调整方法。
举例而言,如图7所示,本申请实施例的探测装置探测角度的调整方法涉及到的探测装置探测角度的调整装置可以包括:前视摄像头11、图像处理单元22、前毫米波雷达调节机构33、方向盘转角传感器44、前毫米波雷达55。
其中,前视摄像头11可以安装在前风挡玻璃位置,用于探测前方(如100米范围内)道路情况,前视摄像头11采集到的道路视频信息通过LVDS(Voltage Differential Signaling,低电压差分信号)或以太网络传输给图像处理单元22,图像单元22根据视频图像中的道路信息计算出车辆前方道路的弯曲变化值,通过CAN输入给前毫米波雷达调节机构33,前毫米波雷达调节机构33可以根据前方道路的弯曲变化值和车辆上的方向盘转角44及其它车辆姿态数据,综合运算判断当前前毫米波雷达55需要调节的角度,并进行调节。需要说明的是,前视摄像头11和图像处理单元22可以合并为一个总成部件,车前毫米波雷达调节机构33和前毫米波雷达55可以合并为一个总成部件,具体地可以由本领域技术人员根据实际情况进行设计,在此不做具体限定。
如图8所示,下面以一个具体实施例阐述本申请实施例的探测装置探测角度的调整方 法。
步骤S801,通过摄像头采集车前方(如100米范围内)的道路视频信息,并通过LVDS传输给图形处理单元。

步骤S803,若车辆行驶的当前道路车道线不清晰或无车道线,则采集方向盘当前转角信息,综合计算判断,跳转至步骤S807;
步骤S804,若车辆前方道路线清晰可识别,则图形处理单元根据采集到的道路信息,进行处理计算,识别出路面上的道路线、马路牙或路灯等道路识别信息计算出道路的弯曲程度,再根据道路的弯曲程度判断车辆前方是否处于弯道路况,若不是弯道路况,则丢掉当前的视频数据,继续更新计算下一时刻的视频数据,并进行处理计算,以此循环。
步骤805,当计算出车辆前方为弯道道路,则保留此有效数据,并根据当前的车道线详细计算输出前方道路的第一弯道信息。
步骤S806,获取车辆的方向盘的转角信息,判断转角信息对应的探测装置的探测角度与调整后的探测装置的探测角度是否匹配,如果两个探测角度不匹配,则利用转角信息对应的探测装置的探测角度对调整后的探测装置的探测角度进行更新,以此循环。
步骤S807,若需要调整前毫米波雷达的角度,则通过CAN输出需要调整的目标角度值。
步骤S808,调整至目标角度,并在调整到位后,则继续更新下一时刻的数据,以此循环。
