Stage Camera Route Planning Using Performer and Lighting Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to determine an optimum route for a camera moving on a stage that avoids collisions with performers and stage equipment while maintaining audience line-of-sight during live performances, as they do not consider dynamic changes in performer positions, lighting, and object arrangements.
Innovation Solution
An information processing device generates a potential map defining travel allowance areas where the probability of collision with performers or objects is below a threshold, using action schedule data of performers, object arrangement data, and lighting control data, to determine a safe and inconspicuous route for the camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera moves freely on the stage to capture various angles, then the image capture quality is improved, but the risk of collision with performers and stage equipment increases
Solution Approach 1:
The system performs preliminary actions by pre-acquiring action schedule data of performers, arrangement schedule data of objects, and lighting control data before the performance. A potential map is generated in advance that defines travel allowance areas where collision probability is below a threshold. The camera then moves according to this pre-computed map, ensuring safe movement while maintaining good capture positions.
Solution Approach 2:
The patent introduces a potential map as an intermediary between the camera and the stage environment. This map acts as a mediator that encodes safety information about performer positions, object locations, and lighting conditions. The camera refers to this intermediate representation to make movement decisions, rather than directly sensing and reacting to the complex stage environment in real-time.
2Object-affected harmful factors
If the camera stays at fixed positions to avoid disturbing the audience, then the audience line-of-sight is maintained, but the variety of captured angles is limited
Solution Approach 1:
The system resolves this contradiction by making the camera position dynamic rather than fixed. The potential map defines travel allowance areas that enable the camera to move to various positions on stage. By dynamically adjusting camera position within safe zones, the system captures diverse angles while staying invisible to the audience, combining movement flexibility with audience comfort.
3Productivity
If the camera moves rapidly to capture different positions, then the productivity of image capture is improved, but the risk of collision with performers increases
Solution Approach 1:
The system performs preliminary computation to generate a potential map that pre-identifies safe travel paths and allowance areas. This advance preparation enables the camera to move efficiently along predetermined safe routes without real-time collision detection, achieving high-speed movement while maintaining low collision probability through pre-planned trajectories.

AI summary
A map for determining a safe traveling route that does not collide with a performer or an object on a stage is generated, and an image capturing robot is caused to travel according to a route determined on the basis of the map. A potential map in which a traveling allowance area of the image capturing robot that moves on a stage and captures an image is defined is generated. A data processing unit acquires action schedule data of a performer, arrangement schedule data of an object on a stage, and control schedule data of a lighting on the stage, and generates, on the basis of the acquired data, a potential map in which an area that does not collide with a performer or an object and is inconspicuous by a lighting is defined as a travel allowance area.
