Remote distance measurement method based on plurality of images

Abstract

The invention discloses a remote distance measurement method based on a plurality of images. The method comprises the following steps of: controlling a cloud deck according to a measured object positioning instruction from a distance measurement client and adjusting an optical zooming camera; sending a collected measured object image to a control center; controlling the cloud deck according to a target point positioning instruction from the distance measurement client; adjusting the optical zooming camera; sending an angle value, which is relative to a standard line, of a connecting line of cloud deck returning measurement points and measured object target points to the control center; and obtaining a distance between the two measured object target points according to the angle value, which is relative to the standard line, of the connecting line of the measurement points and the measured object target points, and the distance between the two measured object target points. According to the remote distance measurement method disclosed by the invention, a manner of combining the controllable cloud deck with a network video is adopted and a laser distance measurement instrument does not need to be adopted; and distance measurement work of a measured object in a construction site can be finished through clicking of a mouse at the distance measurement client so that a user can conveniently monitor a real-time condition of the construction site remotely.

Description

technical field [0001] The invention belongs to the field of measurement technology and video monitoring, in particular to a multi-image-based remote ranging method. Background technique [0002] The construction industry is one of the important material production sectors and pillar industries of my country's national economy. At the same time, the construction industry is also a high-risk industry with frequent safety accidents. Therefore, it is necessary to strengthen the safety management of the construction site, reduce the frequency of accidents, and eliminate various violations. Civilized construction, improve the quality of construction projects. At present, the way to improve the intelligent supervision of construction projects is to install and arrange cameras on the construction site. In the case of panoramic monitoring of the project, it is often necessary to measure the buildings and construction equipment on site. The traditional manual measurement method uses ...
