Abstract
一种测距装置及其扫描机构、控制方法、可移动平台,该扫描机构(3)包括:多个光学元件(31);多个电机(32),与多个光学元件(31)相对应,电机(32)具有中空的转子,光学元件(31)安装在对应电机的转子上;和一个控制器(331),控制器(331)控制多个电机(32);或多个控制器(331),至少一个控制器(331)控制至少两个电机(32);当一个控制器(331)控制至少两个电机(32)时,控制器(331)基于第一同步控制策略控制至少两个电机(32)以预定角度差转动;当一个控制器(331)控制一个电机(32)时,控制器(331)基于第二同步控制策略控制电机(32)与其他至少一个电机(32)以预定角度差转动。采用不同的控制策略控制多个电机(32)以预定角度差转动,实现多个电机(32)的位置同步,减小多个光学元件(31)之间的角度差的波动。
