Embodiment Construction

[0038] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the image processing method of the present invention. Such as figure 1 As shown, the image processing method among the present invention comprises the following steps:

[0039] 101: Acquire a structured light infrared image of a target object.

[0040] Wherein, the structured light infrared image is an infrared image with a structured light pattern.

[0041] In order to obtain the feature information of the target object, the target area where the target object to be acquired is located is firstly determined, and a structured light pattern is projected on the target area. Wherein, the structured light pattern is a randomly arranged speckle pattern.

[0042] The speckle pattern can be projected by various methods. In one of the embodiments, the ground glass is irradiated by an infrared laser light source to generate interference in the target area to form an irregular speckle pattern.

Abstract

The invention discloses a picture processing method and device. The picture processing method comprises acquiring the infrared picture of structured light from a target object, computing the infrared picture of the structured light, and synchronically obtaining the deep picture and infrared picture of the target object from the infrared picture of the structured light. Through the way mentioned above, the invention greatly increases the hit rate of recognition and improves the efficiency of picture recognition. Furthermore, the way of obtaining the deep picture and infrared picture from the infrared picture of the structured light can effectively reduce computed amount, accelerate picture processing speed, and decrease the power consumption of picture processing equipment and the whole cost, compared with prior art.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] In the field of artificial intelligence and image processing, many functions can be realized by using the image information of the target, such as analyzing the user's expression or action information, etc. Image acquisition and recognition has always been a hot research topic, involving many aspects of users' daily life and scientific research. [0003] Obtaining the depth image and infrared image of the target for feature extraction and recognition can improve the recognition hit rate based on RGB image. At present, the infrared image and the depth image of the target object are generally obtained directly through the infrared camera and the depth camera respectively, and there is a lack of a faster and lower-cost method for synchronously acquiring infrared and depth images.
