The embodiment of the invention relates to the field of image processing, and discloses a face recognition method, electronic equipment and a storage medium. In some embodiments of the invention, the face recognition method comprises the following steps: acquiring a two-dimensional image, and acquiring a normal graph corresponding to the two-dimensional image based on the two-dimensional image; obtaining a two-dimensional feature vector corresponding to the two-dimensional image and a three-dimensional feature vector corresponding to the normal graph; fusing the two-dimensional feature vector and the three-dimensional feature vector to obtain a final face feature vector; and performing face recognition based on the final face feature vector. In the implementation mode, the acquisition cost of three-dimensional information is reduced, multi-modal face recognition under single-modal data is realized, and the accuracy of face recognition is improved.
Description
technical field [0001] The embodiments of the present invention relate to the field of image processing, and in particular, to a face recognition method, electronic equipment, and a storage medium. Background technique [0002] Two-dimensional color image face recognition technology has been successfully applied in many fields. However, in practical application scenarios, the recognition rate of face recognition systems often decreases due to the influence of lighting, background, posture, clarity and other conditions. 3D information is less affected by illumination, background, clarity, etc. Therefore, 3D face recognition technology has become a research trend in the field of face recognition. [0003] However, the acquisition of 3D information often needs to be collected by equipment such as depth cameras or laser radars, and the cost of data acquisition equipment is relatively high. For a face recognition system with only two-dimensional data acquisition equipment, it i...
