US 9,432,593 B2 · Target object information acquisition method and electronic device

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.

A method for acquiring information of a target object applied in an electronic apparatus, comprising:

transmitting disperse point light to a target region by a first infrared transmitter in the electronic apparatus, wherein, at least one object is included in the target region;
receiving first reflected light output by the at least one object reflecting the disperse point light in a first time period by a photoreceptor in the electronic apparatus and generating a depth image corresponding to the target region based on the first reflected light;
acquiring information of target image of the target object in the at least one object based on the depth image;
transmitting scattered light to the target region by a second infrared transmitter in the electronic apparatus;
receiving a second reflected light outputted by the at least one object reflecting the scattered light in a second time period after the first time period by the photoreceptor and generating a feature image corresponding to the target region based on the second reflected light;
and
acquiring feature information of the target object based on the feature image and the information of target image.
