Distance measuring method and device

Abstract

The embodiment of the invention provides a distance measurement method and a distance measurement device. The distance measurement method comprises the following steps: acquiring a first image through a first lens; acquiring a second image through a second lens, wherein the first lens and the second lens are positioned at different positions; determining an observing included angle of the first lens according to the first image; determining an observing included angle of the second lens according to the first image, the second image and target pixel characteristics in an observation target; and determining the distance between the first lens and the observation target according to the observing included angle of the first lens, the observing included angle of the second lens and the distance between the first lens and the second lens. According to the scheme, the first image and the second image are respectively acquired through the two lenses positioned at different positions, the observation target is determined according to the images and the target pixel characteristics in an observation target, and the distance is further determined, so that the technical problems existing in the existing distance measurement method such as complicated measurement process, great errors and not practicality are solved, and the technical effect of rapidly and accurately measuring the distance is achieved.

Description

technical field [0001] The present application relates to the technical field of geological surveying, in particular to a distance measuring method and device. Background technique [0002] In actual geological survey work, it is often necessary to measure distance. For example, geophysical field acquisition often encounters complex terrain such as swamps and dangerous mountains where measurement equipment is difficult to locate, or where trees, buildings, etc. are blocked, or where there is no GNSS signal coverage. Due to construction requirements, it is often necessary to measure the distance of certain objects within the visible range of these areas, such as construction areas, distant mountains, etc. [0003] At present, the commonly used field distance measurement method generally uses professional measurement tools, such as chain rulers, GNSS equipment, laser range finders, etc., to measure the distance of the target object. However, in actual implementation, the abo...
