Embodiment Construction

[0019] The video super station instrument and its measurement method are different from the existing technology, and have been greatly improved, specifically:

[0020] 1. A video super station instrument: integrating CCD (Charge-Coupled Device) area array digital camera, GPS (Global Position System, Global Positioning System), and electronic total station (Electronic Total Station), the camera is installed on the upper side of the telescope It is fixed with the telescope, the direction of the main optical axis of the camera is parallel to the telescope, and the image plane passes through the transverse axis of the total station; the GPS antenna is placed on the handle of the total station in a foldable manner, coaxial with the total station.

[0021] 2. A measurement method of a video superstation instrument: at first, use PDA as a tool, take Win CE as an operating platform, integrate GPS data acquisition, coordinate solution calculation, and store; Automatic recording, coordi...

Abstract

The invention discloses a design concept of a video overstation instrument, an integrated video overstation instrument and a method for forest measurement. The instrument is based on WinCE-based handheld computer PDA as the core, integrated digital CCD (Charge-CoupledDevice) area array camera, GPS (Global Position System, Global Positioning System), electronic total station (Electronic Total Station) in one, to solve the The problem of automatic, real-time and rapid measurement, calculation and storage of the spatial three-dimensional coordinates of the target area. The video super station instrument is used to observe the standing trees in forest resources monitoring, including diameter at breast height, arbitrary tree height diameter, tree height, canopy structure, etc., which can quickly and accurately solve the measurement of standing trees, which is the best dynamic monitoring of forest growth. Methods.

Description

1. Technical field [0001] The present invention is a new type of equipment integrating digital CCD (Charge-Coupled Device) area array camera, GPS (Global Position System, Global Positioning System) and electronic total station (Electronic Total Station), which is used for fast three-dimensional close-range target information Acquisition can automatically, quickly and real-time solve and store the spatial three-dimensional coordinates of the target area to be measured. With this equipment as the core, together with digital image 3D information extraction and 3D target model generation software, together constitute a fast imaging 3D measurement of close-range targets with positioning, precise point measurement, close-range target imaging, automatic or semi-automatic 3D measurement, and 3D model generation. system. Especially for tree trunk analysis measurement in forest resource monitoring, including diameter at breast height, arbitrary tree height diameter, tree height, canopy...
