Wearable Headframe Camera Coordinated Object Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of devices and systems that enable a user with a mobile camera to track a moving object, causing a second camera to also track the object from a different position and imaging angle, effectively coordinating the tracking between multiple cameras.
Innovation Solution
A system comprising a first computing device with a camera, display, and communication circuitry, and a second portable computing device with geospatial coordinate generation capabilities, allowing the first device to guide the second device to position the object within its field of view, using geospatial coordinates and actuator-controlled platforms for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user operates a first mobile camera to track a moving object, then the user can manually adjust the camera to follow the object, but a second camera cannot automatically track the same object from a different position
Solution Approach 1:
The system continuously receives location data from the moving object via GPS/geo-spatial coordinates, calculates the optimal camera pose to maintain the object within the field of view, and adjusts the camera position in real-time based on this feedback loop
Solution Approach 2:
A processor acts as an intermediary between the location data source and the camera control system, calculating the required camera pose based on geospatial coordinates and communicating this to the actuator-controlled platform
2Stability of the object's composition
If a second camera is positioned at a fixed location, then the camera structure is simple and stable, but it cannot follow or track a moving object
Solution Approach 1:
The camera system transitions from a static fixed position to a dynamic positionable system where the camera can move along predefined paths and adjust its pose based on the real-time location of the tracked object
Solution Approach 2:
The system pre-calculates the camera pose requirements based on the object's current position and movement trajectory, allowing the camera to be positioned optimally before the object enters the field of view
3Measurement precision
If the camera is mounted on an actuator-controlled platform for precise positioning, then the camera can achieve accurate tracking, but the device complexity increases
Solution Approach 1:
The system uses the moving object's own GPS location data to determine camera positioning requirements, eliminating the need for complex external positioning systems or manual intervention
Data Source
AI summary
Methods and apparatus track an object with a first camera causing a second camera to also track the object. The object is a moving object. Geospatial coordinates, including an elevation or altitude of a camera are determined on the camera. A pose of the camera, including a pitch angle and an azimuth angle are also determined. Azimuth is determined by a digital compass. A camera pose including pitch is determined by accelerometers and/or gyroscopes. Cameras are communicatively connected allowing to display an image recorded by one camera being displayed on a second camera. At least one camera is on a movable platform with actuators. Actuators are controlled to minimize a difference between a first image of the object and a second image of the object. Cameras are part of a wearable headframe.
