Portable manual multi-angle observation frame

Abstract

The invention discloses a potable manual multi-angle observing scaffold, which mainly comprises a tripod, a rotary base, an inclination angle adjusting device, and a main rod and a cross rod, wherein the tripod is fixed at the lower end of the rotary base, the upper end of rotary base is provided and fixed with a wire wheel of which one end has a crank and provided with a center shaft, the bottom of the main rod is fixed with the center shaft, one end of each of two shorter side auxiliary tubes is fixed on the upper end of the rotary base, the other ends of the two shorter side auxiliary tubes separate at a certain angle, the end parts of the other ends of the two side auxiliary tubes are fixed with wheels respectively, two ends of a stainless steel wire rope are both fixed at a proper position a the main rod after the stainless steel wire rope goes around two wheels and the wire wheel, one end of the cross rod is fixed on the top of the main rod, and the other end of the cross rod is provided with a fixed plate for mounting a sensor probe. The observing scaffold can solve the technical problems of the major part of the prior multi-angle measurement system such as high cost, low portability, signal measured height and serious shadow interference of the apparatus in a hotspot direction.

Description

technical field [0001] The invention belongs to the field of geosciences, and in particular relates to remote sensing ground observation technology. Background technique [0002] The acquisition of multi-angle remote sensing experimental data is one of the key points in the development of remote sensing. In addition to the special radiation measuring instruments for remote sensing, multi-angle observation devices are also required. The existing multi-angle measurement devices are mainly divided into two categories according to their measurement methods: [0003] (1) The sensor conducts hemispherical scanning around a fixed central point, such as PARABOLA of JPL in the United States, a portable surface and atmospheric anisotropy measurement device (Deering, 1986, Remote Sensing of Environment; Abdou, 2000, Journal of Geophysical Research). The inconsistency of the target objects measured from various angles leads to the uniformity of the target objects; [0004] (2) Keep the...
