A first frame of time of flight (TOF) data including projection off data and infrared data is obtained, and after determining that a data block satisfying that a number of data points with values greater than a first threshold is greater than a second threshold is present in the infrared data, TOF data for generating a first frame of a TOF image is obtained based on a difference between the infrared data and the projection off data. Because the data block satisfying the number of data points with values greater than the first threshold is greater than the second threshold is an overexposed data block, and the projection off data is TOF data acquired by a TOF camera with a TOF light source being off, the difference between the infrared data and the projection off data can correct the overexposure, improving quality of the first frame of the TOF image.

Data obtaining method and apparatus

This application provides a data processing method and an apparatus. The data processing method includes: acquiring a first frame of time-of-flight (TOF) data; processing the first frame of TOF data into a TOF image; and performing face recognition by using the first frame of TOF image to obtain a recognition result. When TOF data is used for face recognition, higher security can be achieved. In addition, the first frame of TOF image is used for face recognition immediately after the first frame of TOF image is obtained, so that the execution speed is high. Because the TOF data is less affected by light, a high-quality TOF image can be obtained even if the first frame of TOF data is used, and therefore, the recognition accuracy is high.

Data processing method and apparatus

Embodiments of this application provide a face recognition method and apparatus, including: obtaining TOF data; processing the TOF data into a TOF image in a TEE; and performing face recognition by using the TOF image, to obtain a recognition result. Because the TOF data is used for face recognition, higher security is achieved. Implementation in the TEE can further improve the security.
