Abstract
Disclosed are a target object information acquisition method and an electronic device. The target object information acquisition method comprises a first infrared transmitter transmitting scattered light to a target area comprising at least one object; a photoreceptor receiving first reflected light output after at least one object reflects the scattered light in a first time period, and generating a depth image corresponding to the target area, acquiring the target image information about a target object; a second infrared transmitter transmitting scattered light to the target area; the photoreceptor receiving second reflected light output after at least one object reflects the scattered light in a second time period, and generating a feature image corresponding to the target area; and acquiring feature information. By means of the time division, the present invention solves the technical problem of a low acquisition rate for target object information in the prior art.
