Abstract
Embodiments of the present disclosure provide a method and a device for acquiring depth information, as well as a gesture recognition apparatus. The method includes: projecting an infrared spectrum to a target object; collecting the infrared spectrum reflected by the target object at different positions and generating a first infrared image and a second infrared image respectively; and processing the first infrared image and the second infrared image on a basis of infrared spectrum response characteristics to acquire the depth information of the target object.
