Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tripods for 3D modeling lack the ability to accurately measure camera height and direction, as they often fail to maintain consistent height and cannot reliably record the direction of capture, making it difficult to correct camera tilt and align the lens properly.
Innovation Solution
A tripod design featuring a telescopic rod with locking mechanisms, a mobile phone holder, and a floor stand with contrasting colored foot covers for height measurement, combined with a method using a mobile phone's sensors to determine camera direction, allowing for accurate height and direction calculation through image analysis and sensor data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple support structure is used for the camera, then the device complexity is reduced, but the measurement precision of camera height and direction deteriorates
Solution Approach 1:
The patent introduces a mobile phone as an intermediary device that captures images and provides sensor data (accelerometer, gyroscope, compass) to measure camera height and direction. The mobile phone holder serves as a mediator to securely mount the phone on the tripod, enabling precise measurements without complicating the tripod structure itself.
Solution Approach 2:
The patent replaces complex mechanical measurement mechanisms with electronic sensors (accelerometer, gyroscope, compass) in the mobile phone. This substitution allows for precise measurement of camera parameters through software processing of sensor data rather than through mechanical measurement systems.
2Manufacturing precision
If height adjustment mechanisms are added to maintain consistent camera lens height, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The patent enables the system to self-measure and self-correct camera height using the mobile phone's accelerometer and gyroscope sensors. The software automatically calculates camera lens height based on sensor data and image analysis, eliminating the need for manual height adjustment mechanisms while maintaining consistent height measurement.
Solution Approach 2:
The patent replaces mechanical height adjustment mechanisms with electronic sensor-based measurement and software-based correction. The accelerometer, gyroscope, and image processing algorithms substitute for physical adjustment mechanisms, achieving height consistency without adding mechanical complexity.
3Measurement precision
If adjustment mechanisms are added to correct camera tilt, then the measurement precision of camera direction is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent implements feedback through the mobile phone's sensors (accelerometer, gyroscope, compass) that continuously monitor camera direction and provide real-time data for correction. The software processes this feedback data to calculate and display camera orientation, enabling automatic correction without manual adjustment mechanisms.
Solution Approach 2:
The patent replaces mechanical tilt adjustment mechanisms with electronic sensor-based measurement and software-based correction. The mobile phone's sensors and processing algorithms substitute for physical adjustment mechanisms, improving measurement precision while maintaining ease of operation through automated digital correction.

AI summary
The present disclosure discloses a tripod for 3D modeling and a method for determining camera capture parameters, including the height and the direction of the camera lens. The tripod includes a telescopic rod, a mobile phone holder, a mounting support, and a floor stand. The telescopic rod is formed by multiple sections of nested hollow round rods, and the round rods can be extended and locked. The mobile phone holder is attached to the telescopic rod through a mobile phone holder install base. The mounting support is set on the top of the telescopic rod. The floor stand is set at the bottom of the telescopic rod. The telescopic rod is vertically set on a plane through the floor stand. There are three sets of the floor stand brackets that are evenly set around the telescopic rod. According to the present disclosure, contrasting colors are used at the bottom of the tripod where it touches the floor to help recognize these points. The height of the tripod can be accurately calculated by measuring the distance between these points in the image captured by the camera. The mobile phone holder is attached to the tripod, and a direction sensor of the mobile phone is used to record the direction during capture, so that the direction of camera capture can be obtained even when the camera does not have a direction sensor. The tripod features a simple structure, easy operation, low costs, and a compact storage which is easy to carry.
