Method for presenting face in video call, video call apparatus, and vehicle

An apparatus comprising:

• a non-transitory memory configured to store instructions;
• and
• a processor coupled to the non-transitory memory, wherein when executed by the processor, the instructions cause the apparatus to:
• obtain, based on a face image of a user in a video call process, a key feature point of a facial expression of the user, wherein the face image comprises N infrared images of the user and a color face image of the user, and wherein N is an integer greater than 0;
• obtain, based on the N infrared images and the color face image, a three-dimensional (3D) head point cloud information of the user;
• construct, based on the 3D head point cloud information, a 3D head image of the user;
• drive, using the key feature point, the 3D head image to obtain a first target 3D avatar of the user, wherein the first target 3D avatar has an expression of the user;
• rotate, based on a preset presentation angle, the first target 3D avatar to obtain a second target 3D avatar at the preset presentation angle;
• and
• send, to a peer video call device, the second target 3D avatar.

A vehicle comprising:

• a video call system comprising:
• a processor configured to:
• obtain, based on a face image of a user in a video call process, a key feature point of a facial expression of the user, wherein the face image comprises N infrared images of the user and a color face image of the user, and wherein N is an integer greater than 0;
• obtain, based on the N infrared images and the color face image, a three-dimensional (3D) head point cloud information of the user;
• construct, based on the 3D head point cloud information, a 3D head image of the user;
• drive, using the key feature point, the 3D head image to obtain a first target 3D avatar of the user, wherein the first target 3D avatar of the user has an expression of the user;
• rotate, based on a preset presentation angle, the first target 3D avatar to obtain a second target 3D avatar at the preset presentation angle;
• and
• transmit the second target 3D avatar;
• and
• a communications apparatus coupled to the processor and configured to:
• receive the second target 3D avatar;
• and
• send, to a peer video call device, the second target 3D avatar.
