Solution Overview

Problem

Traditional motion capture systems face challenges in accurately capturing the movements of multiple individuals simultaneously, leading to inaccuracies and increased costs due to the need for intensive coordination and extensive editing to avoid overlaps during multiple shooting cycles.

Innovation Solution

A computer-implemented method and system that coordinates motion capture by obtaining and combining video data from multiple shooting cycles, allowing actors to view previous takes in real-time to synchronize their movements, thereby reducing the need for extensive editing and minimizing actor overlaps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional motion capture systems use large groups of individuals for multiple shooting cycles, then more movement data can be captured, but coordination becomes more complex and inaccuracies increase

Engineering Contradiction:
Improvequantity of movement dataVSAvoidcoordination complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The system creates a digital copy (ghost image) of the first actor's movements and displays it to the second actor during the second shooting cycle. This allows the second actor to accurately replicate or interact with the first actor's movements without requiring complex real-time coordination between multiple physical actors.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The first actor's movements are captured and processed into a ghost image before the second shooting cycle begins. This preliminary action provides the second actor with advance information about the first actor's movements, enabling more accurate coordination without increasing on-set complexity.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If traditional motion capture systems conduct multiple shooting cycles with different actors, then more character interactions can be captured, but editing time and costs increase due to overlaps

Engineering Contradiction:
Improvecharacter interaction varietyVSAvoidediting time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system provides real-time feedback by displaying the ghost image of the first actor's movements to the second actor during the second shooting cycle. This feedback mechanism allows the second actor to adjust their performance to avoid overlaps and coordinate accurately, reducing the need for extensive post-production editing.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

By preparing the ghost image before the second shooting cycle and providing it to the actor in advance, the system enables the actor to plan and execute movements that avoid overlaps with the first actor, thereby reducing editing requirements.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If traditional motion capture systems use intensive coordination among large groups, then more realistic interactions can be achieved, but inaccuracies in captured movements increase

Engineering Contradiction:
Improveinteraction realismVSAvoidmovement accuracy
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The system uses a digital copy (ghost image) of the first actor's movements instead of requiring physical presence and coordination with another actor. This eliminates coordination errors while maintaining interaction realism, as the second actor can accurately reference the ghost image to achieve realistic interactions.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The first actor's movements are captured and converted into a ghost image before the second shooting cycle. This preliminary capture ensures high precision in the reference movements, which the second actor can then accurately follow or interact with, maintaining both realism and precision.

Inventive Principle:
Principle #10Preliminary action
