Problems solved by technology

[0002] Existing 3D camera devices usually use two image sensors of two cameras to obtain at least two images from different angles for the same target scene to calculate the 3D coordinate information of the target scene. The volume is relatively large, and the two cameras also cause the cost of the three-dimensional camera device to be relatively high, so it is necessary to improve
In addition, the face recognition method using a three-dimensional camera device generally judges whether the obtained three-dimensional coordinate information of the face is consistent with the preset template to determine whether the face recognition is passed. Long, resulting in a long time for the existing face recognition method and poor user experience

Abstract

The invention relates to a three-dimensional image photographing device, a three-dimensional image photographing method and a face recognition method. The three-dimensional image photographing devicecomprises a laser source, an image sensor and a data processing module. The laser source is used for transmitting laser. The image sensor is used for sensing visible light for generating a two-dimensional image signal of an objective scene and sensing the laser which is reflected from the objective scene for generating a depth image signal. The data processing module is used for acquiring the two-dimensional coordinate of the objective scene according to the two-dimensional image signal, and acquiring the depth coordinate of the objective scene according to the depth image signal, thereby obtaining the three-dimensional coordinate information of the objective scene.

Description

technical field [0001] The invention relates to a three-dimensional camera device, a three-dimensional camera method and a face recognition method. Background technique [0002] Existing 3D camera devices usually use two image sensors of two cameras to obtain at least two images from different angles for the same target scene to calculate the 3D coordinate information of the target scene. The volume is relatively large, and the cost of the three-dimensional camera device is relatively high due to two cameras, so it is necessary to improve it. In addition, the face recognition method using a three-dimensional camera device generally judges whether the obtained three-dimensional coordinate information of the face is consistent with the preset template to determine whether the face recognition is passed. It takes a long time, which leads to a long time for the existing face recognition method and poor user experience. Contents of the invention [0003] In view of this, a th...
