Abstract

The invention discloses a single-mass vibration fuzzy image acquisition and vibration parameter visual measurement experiment platform. The platform comprises a single-mass vibrator and a camera. The single-mass vibrator is connected with a vibrator exciter, the vibration exciter is controlled through a frequency converter, the vibration exciter drives the single-mass vibrator to vibrate, the single-mass vibrator is connected with the camera, and an independently fixed visual scaling board is arranged below the lens of the camera. According to the invention, the single-mass vibrator vibrates under the effect of the vibration exciter, a binocular stereo camera connected with a timbre vibrator vibrates together, and fuzzy images during vibration can be acquired through the lens of the vibrating camera. The experiment platform provides an experiment means for realizing acquisition of the vibration fuzzy images and image restoration. Research data under different vibration conditions can be obtained by changing the frequency and amplitude of the vibration conveniently through the frequency converter. An ideal experiment means is provided for analysis of degradation causes of the vibration fuzzy images, restoration of the vibration fuzzy images and vision-based vibration parameter measurement.

Description

technical field [0001] The invention relates to a vibration image acquisition device, in particular to an experimental platform for single body vibration fuzzy image acquisition and vibration parameter visual measurement. Background technique [0002] Visual recognition and measurement technologies are more and more widely used, but due to the interference of vibration factors, the collected images are often blurred, which brings difficulties to the further application of the images. [0003] At present, there is still a lack of a controllable experimental platform for the study of vibration image phenomena in China. A vibration fuzzy image generation, controllable vibration amplitude and frequency, and a vibration parameter measurement device based on vision can be used to invent a vibrating body. Great application value. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an experimental platform for single-mass v...
