Description

Portable near-ground remote sensing imaging scanning bench device

Technical Field

The utility model relates to a near ground remote sensing technical field specifically is a portable near ground remote sensing formation of image scanning rack device.

Background

The utility model relates to the technical field of near-field remote sensing, including fields such as ecological near-field remote sensing, agricultural near-field remote sensing, crop phenotype analysis, forestry near-field remote sensing.

The utility model discloses under being applied to open-air environment, carry on various remote sensing imaging sensors such as high spectrum formation of image, infrared thermal imaging, multispectral formation of image, high definition RGB formation of image, carry out the purpose of quick, normal position, non-damage remote sensing imaging scanning to targets such as earth's surface vegetation, crops, forest trees, ecological environment key element.

In the technical field of near-earth remote sensing, a portable scanning platform frame capable of carrying remote sensing imaging sensors such as hyperspectral imaging, infrared thermal imaging, multispectral imaging and RGB imaging is lacked at present.

The existing scanning platform capable of being used for field, in-situ and rapid remote sensing measurement mostly uses a large-scale platform frame which is ready-made and fixedly installed, the structure uses a large-scale gantry crane steel frame structure, the gantry crane steel frame structure must be fixed on a very firm foundation, once the gantry crane steel frame structure is built, the gantry crane steel frame structure cannot move, and only the same land can be fixedly scanned. And the construction cost is high, the operation is complex, the use is inconvenient, the expansibility is poor, and the maneuverability and flexibility are lacked.

The heavy-duty movable sliding rail for industrial use must be provided with a high-power battery or an industrial alternating current and a controller at one end of a motor. When in use, a professional is required to press the button manually for controlling the movement and the stop. And the other personnel are responsible for controlling the remote sensing imaging sensor arranged on the scanning platform to collect data. The manpower cost is additionally increased.

According to the scheme of the large-scale rack lacking the portable storage characteristics, in the using process, a power line and a control cable of a camera are inevitably exposed outside, weather, corrosion and back-and-forth dragging friction are suffered for a long time, the connection stability of a power supply and a data cable of an imaging sensor is seriously affected, and the risk of damage to the imaging sensor caused by cable short circuit is very high.

Generally, the existing scheme is a large-scale device formed by splicing different modules, and has a series of defects of no mobility, portability and expansibility, inconvenient installation, use, maintenance and removal and the like. Is not suitable for field portable transportation, mobile use and in-situ measurement.

The existing scheme does not comprise an automatic scanning arm, a foldable supporting rod and a foot rest which can carry remote sensing imaging sensors such as hyperspectral imaging, infrared thermal imaging, multispectral imaging and RGB imaging. The technical problems of folding, portable transportation, easy installation and use and automatic moving and scanning cannot be solved.

In the existing scheme, a large gantry crane steel frame structure is usually used, the installation of a movable sliding rail needs to be finished by drilling a foundation and paved on the ground, and professional construction and installation are needed. And great difficulty is caused to later maintenance, use and removal. And the weight of the cross shaft carrying the imaging sensor is hundreds of kilograms, the inertia is large during normal work, the synchronous movement of the two ends of the cross shaft cannot be ensured, the leveling is very difficult, the accurate automatic movement control function is not provided, and the data acquisition efficiency and the data quality are seriously influenced.

The imaging sensor-carrying ground cross shaft used in the existing scheme is fixedly arranged on steel frames with fixed heights on two sides, so that the height adjusting function in the vertical direction cannot be realized. In addition, in the process of moving and acquiring data of the camera, a power cable and a data cable of the camera are exposed and leaked outside and are dragged back and forth along with the movement of the camera, so that the camera is not attractive, is easily weathered, corroded or scratched, influences the stability of the connection between the camera and a computer interface, and simultaneously has the risk of damage to the camera caused by cable short circuit.

In the existing scheme, in order to stably install a large-scale gantry crane structure on the ground, a large-scale foundation needs to be excavated, and the gantry crane structure can be fixedly installed only once. Once installed, it cannot be moved elsewhere. The structure only considers the firmness of ground installation, cannot realize convenient and quick removal, has large floor area, damages soil and environment and extremely low cost performance.
