Embodiment Construction

[0016] 1) Video Super Station: It integrates 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 and the telescope Fixed together, the direction of the main optical axis of the camera is equal to that of 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.

[0017] 2) Video super station measurement software: with PDA as tool and Win CE as operating platform, it integrates GPS data acquisition, coordinate calculation and storage; Calculation and storage; the automatic shooting of the digital camera, image storage and the calculation of the three-dimensional space coordinates are integrated to realize automatic, fast and real-time calculation of the three...

Abstract

This invention discloses video super station design and a method of forest measurement integrated with the station. The device is based on WinCE PDA core and integrated with CCD cameral, GPS, and electronic total station. The video super station device is used for observation of the forest.

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...
