Abstract
With the development of intelligent technology, it is of great significance to develop intelligent equipment with topography self-sensing function. The micro morphology perception technology applied to intelligent equipment is the key technology for development. In this paper, at first, topography perception theory based on the PVDF (Polyvinylidene Fluoride) technology is researched, then an experimental study is conducted to sense the characteristic points of the geometric curve of the preset topography surface used in the PVDF film, and then the Ferguson curve model is used to reconstruct the topography characteristic curve. The experimental results show that the reconstruction curve can truly reflect the features of the characteristic curve of the surface of the preset topography, and the feasibility of topography surface sensing technology by PVDF sensing technology is verified. The research provides technical support for the development of intelligent equipment with topography self-sensing function.

LabVIEW software was used to collect experimental data, which was imported into MATLAB to reconstruct a three-dimensional topography characteristic curve of the sensed sample
Summary
Intelligent manufacturing and intelligent equipment have become research hotspots, and three-dimensional complex topography perception technology is one of the key technologies for the development of intelligent equipment [1,2,3,4,5]. Non-contact topography sensing technology mainly uses electromagnetic sensors [10], optical equipment [11], and other non-contact sensing equipment [12] to perform feature point sensing and data collection of the three-dimensional topography of the object, the data processing of the sensing feature points and the reconstruction of the three-dimensional topography surface characteristic curve and characteristic surface are carried out. The shortcomings of this non-contact sensing technology are: the interference from space-related fields is large, the sensing equipments are expensive, and the sensing cost is high.
