Image synthesis method and apparatus

An image synthesis apparatus, comprising:

• at least one processor;
• and
• at least one memory communicatively coupled to the at least one processor and storing instructions that upon execution by the at least one processor cause the apparatus to:
• acquire an identifier for identifying a virtual object;
• acquire a video captured by an image sensor;
• recognize at least one hand in the video and obtain hand information, wherein the hand information comprises information indicative of at least one key point of the hand;
• acquire image rendering information based on the identifier for identifying the virtual object and the hand information, wherein the image rendering information comprises sequence frames for forming the virtual object and information indicative of an association between the virtual object and the at least one key point of the at least one hand, wherein the image rendering information further comprises a rendering order, wherein the rendering order comprises a first rendering order and a second rendering order, the first rendering order indicates an order of rendering the sequence frames of the virtual object, and the second order indicates an order of rendering the virtual object and the at least one hand;
• perform synthesis rendering on the virtual object and the at least one hand based on the image rendering information to generate a synthetic image;
• and
• display the synthetic image comprising the virtual object and the at least one hand, wherein the virtual object is positioned at the at least one key point of the at least one hand and is movable following a movement of the at least one key point of the at least one hand.

A non-transitory computer readable storage medium, bearing computer-readable instructions that upon execution on a computing device cause the computing device at least to:

• acquire an identifier for identifying a virtual object;
• acquire a video captured by an image sensor;
• recognize at least one hand in the video and obtaining hand information, wherein the hand information comprises information indicative of at least one key point of the at least one hand;
• acquire image rendering information based on the identifier for identifying the virtual object and the hand information, wherein the image rendering information comprises sequence frames for forming the virtual object and information indicative of an association between the virtual object and the at least one key point of the at least one hand, wherein the image rendering information further comprises a rendering order, wherein the rendering order comprises a first rendering order and a second rendering order, the first rendering order indicates an order of rendering the sequence frames of the virtual object, and the second order indicates an order of rendering the virtual object and the at least one hand;
• perform synthesis rendering on the virtual object and the at least one hand based on the image rendering information to generate a synthetic image;
• and
• display the synthetic image comprising the virtual object and the at least one hand, wherein the virtual object is positioned at the at least one key point of the at least one hand and is movable following a movement of the at least one key point of the at least one hand.
