AI Technical Summary

Technical Problem

Existing technologies struggle to effectively address issues such as contact point misalignment, motion trajectory conflict, motion failure, or clipping during object replacement in hinged objects, especially in robot operation scenarios where it is difficult to guarantee physical plausibility and visual realism.

Method used

By acquiring the object models of the original operation scene and the newly added object, the trajectory sequence of the contact points between the actuator and the original object is determined, geometric transformation parameters and visual parameters are calculated, and the original object is automatically replaced with the newly added object to ensure physical rationality and appearance authenticity.

Benefits of technology

It achieves physical plausibility and visual realism of hinged objects in robot operation scenarios, solves problems such as contact point misalignment and motion trajectory conflict, and generates more realistic simulation operation demonstration data.

Abstract

The application provides an object replacement method and an electronic device, and the method comprises the following steps: obtaining an original operation scene and an object model of a new object; determining an original contact point trajectory sequence according to an executor model, pose data of an executor, action data of the executor and object information of an original object; determining geometric transformation parameters of the new object; determining visual parameters of the new object according to original image data corresponding to the original operation scene; and replacing the original object in the original operation scene with the new object based on the geometric transformation parameters and the visual parameters of the new object. The application can automatically replace the original object in the original operation scene with the new object, and can also ensure the physical rationality and the appearance authenticity in the interaction with the real environment during the object replacement, so that the replaced new object can easily adapt to the motion mode of the executor in the original operation scene, thereby generating more real simulation operation demonstration data.
