Angle measurement method and apparatus, scanning apparatus, and laser radar

Abstract

The present disclosure provides an angle measurement method and apparatus, a scanning apparatus, and a laser radar. The angle measurement method comprises: a first angle sensor outputting a first signal; determining a first angle set on the basis of the first signal, the first angle set comprising a first angle value and a second angle value; a second angle sensor outputting a second angle set; determining calibration parameters of the first angle sensor at least on the basis of the first angle value, the second angle value, and the second angle set; and determining a rotation angle of a rotator on the basis of the first signal and the calibration parameters.
