Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional depth camera hardware and basic optical theory are used, then depth information can be captured, but velocity measurement capability is lacking
Solution Approach 1:
The patent pre-calculates and stores velocity parameters (reference pixel numbers, image sensor lengths, lens focal lengths) in configuration files before operation. This preliminary preparation enables the system to quickly compute velocities without complex real-time calculations, resolving the contradiction between measurement capability and system complexity
Solution Approach 2:
The patent replaces complex mechanical velocity measurement systems with image processing and optical theory calculations. By using 2D image data and applying optical formulas to calculate lateral, longitudinal, and oblique velocities, the system achieves velocity measurement without additional mechanical sensors or complex hardware
2Speed
If image processing techniques are applied to measure velocity, then velocity information can be obtained, but real-time calculation capability is insufficient
Solution Approach 1:
The system pre-calculates velocity parameters and stores them in configuration files during system setup. This preliminary action separates complex calculations from real-time operation, enabling fast real-time velocity measurement by simply retrieving pre-computed values and applying simple formulas
Solution Approach 2:
The patent divides velocity measurement into three independent calculation modules: lateral velocity calculation, longitudinal velocity calculation, and oblique velocity calculation. Each module processes specific image parameters independently, enabling parallel computation and improving real-time performance without overwhelming system complexity

AI summary
A depth camera capable of measuring the oblique velocity of an object is provided, wherein a depth camera capable of measuring the lateral velocity of an object includes a depth camera body, a first configuration file, and a lateral velocity calculation system. The lateral velocity calculation system includes: first image-processing software for recording a first depth distance at which images are taken of an object and for calculating the number of pixels corresponding to a lateral movement of the object and the duration of the lateral movement; and lateral velocity calculation software for calculating the lateral velocity of the object. The depth camera capable of measuring the oblique velocity of an object allows the lateral/longitudinal/oblique velocity of an object to be measured in real time using image-related techniques.
