Abstract

The invention relates to an omnibearing tilt sensor based on machine vision, comprising an omnibearing tilt sensor outer case, an LED (Light Emitting Diode) lighting source, a transparent cone container, light-proof liquid, a camera, an embedded system, a power source and a compass, wherein the transparent cone container is a closed container combined by two cones of the same size in a back to back mode; and the light-proof liquid is filled in the container, and the volume of the light-proof liquid is one half of the volume of the container. The light permeable part of the cone container is shot by a front body through the camera in the machine vision mode for analysis, judgement and calculation, and measurement parameters of measured objects, such as tilt angles, tilt azimuth angles, and the like, are obtained. The invention provides the omnibearing tilt sensor based on machine vision with the advantages of simple maintenance and adjustment, high measurement precision, wide measurement range, low manufacture cost, and strong real-time performance and safety as well as reliability.

Description

technical field [0001] The invention relates to a level detection device, which belongs to the application of physics, digital image processing technology, LED technology, embedded technology, network communication technology, level visualization technology and mechanical design technology in level detection, and is mainly suitable for bridge erection, railway Laying, civil engineering, oil drilling, aviation and navigation, industrial automation, intelligent platform, machining and other fields. Background technique [0002] At present, spirit levels can be mainly divided into two types: traditional spirit levels and electronic spirit levels; traditional spirit levels are mainly composed of carriers and straight level tubes. Put the spirit level on the surface of the object to be measured, and the air bubbles in the straight horizontal tube will run to the end at a high level, thus displaying the level / inclination state of the object. This bubble-type level has the followi...
