Inclination Calculation Using Acceleration and Image Data

The patent combines acceleration detection means with imaging means to calculate inclination. The imaging means captures images of imaging targets to determine inclination through image processing, while the acceleration detection means provides acceleration data. By merging these two independent measurement systems, the patent achieves high-precision inclination calculation that overcomes the limitations of using either method alone, particularly eliminating errors caused by inertial forces and vibrations.

The patent employs partial action by selectively using correction processing only when necessary. The system determines whether correction is needed based on the reliability of acceleration data and the quality of image processing results. When image processing successfully provides accurate inclination data, extensive correction processing is avoided. This selective approach maintains high accuracy while minimizing unnecessary calculation time and delays.

The patent implements multi-functionality by designing the imaging means to serve dual purposes: capturing images for inclination calculation and providing reference data for correcting acceleration-based inclination measurements. The imaging targets and processing system are designed to perform multiple functions including initial inclination determination, validation of acceleration data, and correction of measurement errors. This universal approach increases precision without proportionally increasing device complexity.
