Method of automatic zooming control, apparatus, electronic device, and computer readable storage medium applying the method

Abstract

A method of automatic zoom control comprises acquires a speed of a moving device and a speed change signal. A detection distance required by the moving device after a specified time duration is predicted according to the speed of the moving device and the speed change signal. A target focal length of a zoom radar is calculated according to the predicated detection distance, and the focal length of the zoom radar is adjusted to be the target focal length over the specified time duration. The longer detection distance, the focal length will be larger for satisfying with a detecting requirement, a light intensity of the zoom laser does not increase for increasing the detection distance. An energy consumption and a generated heat of the laser radar to be reduced. An apparatus, an electronic device, and a computer readable storage medium applying the method are also disclosed.
