Description
本发明实施例涉及云台技术领域,尤其涉及一种云台的目标位置标记方法、云台与拍摄装置。
云台可以搭载载荷,其中,增稳云台可以稳定搭载在其上的载荷的姿态,也就是使载荷在运动中保持其姿态处于大致静止状态。另外,增稳云台可以控制载荷的移动。以载荷为拍摄装置为例,拍摄装置搭载在增稳云台上后,增稳云台可以稳定拍摄装置的拍摄方向,以保证拍摄装置在移动的过程中拍摄出平稳的画面。
其中,用户可以手持增稳云台进行移动,使得云台跟随用户的移动方向而移动。当用户操作增稳云台移动时,云台基座的角度会发生转动,通常为了避免云台跟随云台基座太紧而导致拍摄装置获取到的画面晃动强烈,云台会以缓启缓停的方式运动以消除与基座之间的角度增量,从而实现跟随移动。但是上述方式中会造成云台的运动与用户的动作之间存在位置上的延迟,当用户的动作停止时,云台仍在运动,所以用户不能准确预判云台的目标位置。

本发明实施例提供了云台的目标位置标记方法、云台与拍摄装置。其中,涉及的云台可以是增稳云台,增稳云台可以应用于可移动平台上,例如无人机等。图1为本发明一实施例提供的云台的基座的示意图,图2为本发明一实施例提供的云台的示意性架构图。如图1和图2所示,在实际使用时,用户可以操作基座来带动云台运动。云台可以包括但不限于如下:三轴电机(包括俯仰(pitch)轴电机1、横滚(roll)轴电机2和偏航(yaw)轴电机3)、yaw轴轴臂5,载荷固定装置6(包含惯性测量元件)、pitch轴轴臂7、roll轴轴臂8、载荷9。其中,图2中以载荷为成像装置为例示出。其中,pitch轴电机1安装在pitch轴轴臂7上,roll轴电机2安装在roll轴轴臂8上,yaw轴电机3安装在yaw轴轴臂5上。其中,云台的基座可以安装在yaw轴电机3的上方, 而且云台的基座可以加装陀螺仪来辅助云台的智能跟随。
应理解,上述云台中各部分的命名仅是出于标识的目的,并不应理解为对本发明的实施例的限制。需要说明的是,云台可以包括上述全部部件或部分部件。
图3为本发明一实施例提供的云台的目标位置标记方法的流程图,如图3所示,本实施例的方法应用于云台中,本实施例的方法可以包括:
S301、在云台的基座转动的过程中,获取所述基座与所述云台的轴臂之间的当前偏移角度。
本实施例中,在云台的基座转动的过程中,可以获得基座与云台的任一轴臂之间的当前偏移角度。
例如,云台上的传感装置感测到云台的基座转动时,可以实时获得基座与云台的轴臂之间的当前偏移角度。
在一些可能的实现方式中,在云台的基座转动的过程中,获取所述基座与所述云台的pitch轴轴臂之间的当前偏移角度,或者,获取所述基座与所述云台的roll轴轴臂之间的当前偏移角度,或者,获取所述基座与所述云台的yaw轴轴臂之间的当前偏移角度。上述的当前偏移角度例如可以是基座的法线与云台的pitch轴轴臂或roll轴轴臂或yaw轴轴臂之间的偏移角度。例如,获取基座在转动前,基座与轴臂之间的夹角1。获取基座转动过程中,基座与轴臂之间的夹角2,根据夹角1和夹角2可以获得基座转动过程中,基座与轴臂之间的当前偏移角度。
在一些可能的实现方式中,在云台的基座转动的过程中,获取所述基座与所述云台的pitch轴轴臂和roll轴轴臂之间的当前偏移角度,或者,获取所述基座与所述云台的pitch轴轴臂和yaw轴轴臂之间的当前偏移角度,或者,获取所述基座与所述云台的roll轴轴臂和yaw轴轴臂之间的当前偏移角度。
在一些可能的实现方式中,在云台的基座转动的过程中,获取所述基座与所述云台的pitch轴轴臂、roll轴轴臂和yaw轴轴臂之间的当前偏移角度。
在另一些可能的实现方式中,上述基座与轴臂之间的当前偏移角度还可以根据安装在轴臂上的电机的转动角度来确定。例如,获得基座转动前,电机的角度1。获取基座转动过程中,电机的角度2,根据角度1和角度2可以获得基座与轴臂之间的当前偏移角度。
在一些可能的实现方式中,若基座上设置第一惯性测量单元(Inertial Measurement Unit,IMU),云台的轴臂上设置有第二IMU,此时,可以从第一IMU中获取所述基座的当前角度,从第二IMU中获取所述轴臂的当前角度,并根据所述基座的当前角度和所述轴臂的当前角度,确定所述当前偏移角度。
其中,第一IMU用于测量基座的当前角度(即三轴姿态角),第二IMU用于轴臂的当前角度(即三轴姿态角),这样可以根据基座的当前角度和所述轴臂的当前角度,确定所述当前偏移角度。例如,将基座的当前角度和轴臂的当前角度相差,得到基座与轴臂之间的当前偏移角度。
可选的,云台的pitch轴轴臂、roll轴轴臂和yaw轴轴臂中至少一个轴臂上设置有第二IMU。这样,可以根据基座的第一IMU和pitch轴轴臂上的第二IMU的测量值,确定基座与pitch轴轴臂之间的当前偏移角度。或者,根据基座的第一IMU和roll轴轴臂上的第二IMU的测量值,确定基座与roll轴轴臂之间的当前偏移角度。或者,根据基座的第一IMU和yaw轴轴臂上的第二IMU的测量值,确定基座与yaw轴轴臂之间的当前偏移角度。

手持云台跟随模式等模式下,由于增稳需要,云台的运动与云台控制人员的动作存在位置上的延迟。当云台控制人员转动基座时,基座的角度会发生转动。此时,云台会以缓启缓停的方式运动以消除基座的角度增量,从而实现跟随控制。这样,会造成云台的运动与基座的动作存在位置上的延迟,造成云台控制人员不能精确知道云台最终稳态下的目标位置。
本实施例,根据上述步骤获得基座在转动过程中,基座与轴臂之间的当前偏移角度,接着,根据该当前偏移角度,确定基座转动到当前位置时,云台的最终目标位置。
在一些实施例中,可以根据上述获得的当前偏移角度,获得基座转动到当前位置时,基座的法线的当前位置。根据法线的当前位置,确定基座转动到当前位置时云台的最终运动目标位置,例如,将法线与云台上成像装置的成像平面的交点位置,作为云台的最终运动目标位置。
在一些实施例中,可以根据上述获得的当前偏移角度,获得基座转动到 当前位置时,轴臂的当前位置。根据轴臂的当前位置,确定基座转动到当前位置时云台的最终运动目标位置。
本实施例,在基座转动的过程中,获取基座与轴臂之间的当前偏移角度,根据该当前偏移角度,确定基座转动到当前位置时云台的最终运动目标位置,进而实现对云台最终运动目标位置的准确确定,防止基座转动时,由于基座与云台之间的运动延迟,造成不能精确知道云台最终稳态下的目标位置。进而提高了云台的控制精度,以及拍摄的准确性。
S303、控制显示装置显示所述最终运动目标位置。
本实施例中,为了便于云台操作人员对云台的操作,则根据上述步骤确定基座转动到当前位置时云台的最终运动目标位置之后,还控制显示装置显示云台的最终运动目标位置,以便云台操作人员直观感知。
可选的,上述显示装置可以是安装在云台上,在成像装置上显示云台的最终运动目标位置。所述显示装置与所述成像装置可以集成在同一装置中,或者,所述显示装置和所述成像装置为两个独立的装置。
