Study of a driftless absolute optical inclinometer system
精东影业 Image Focus
An inclinometer sensor is a device used to measure the angle of inclination of an object.
It is commonly used in various applications such as construction, engineering and geology to determine the slope of terrain and infrastructure.
This project explores the potential of TSP (Triangulation by Shadow Projection) technology applied to determining the spatial position of a pendulum wire using a CMOS-type linear sensor and two LED sources via shadow projection.
This proof-of-concept allowed the technology to be validated in order to continue in a future master's thesis project.
