Methods and systems for estimating physical properties of objects
The present disclosure relates to a method for estimating physical properties of an object. The method includes generating a three-dimensional (3D) reconstruction of a real-world environment based on an input media. Further, the method includes estimating a current set of physical parameters of the object using a physics-based prediction model and a real-world visual content while the object is manipulated. Further, the method includes generating a simulation variant and computing a cost function based on comparing the simulation variant and the real-world visual content. Furthermore, the method includes estimating the physical properties of the object based on optimizing the current set of physical parameters with the cost function such that a similarity between the simulation variant and the real-world visual content increases.
