2results about How to "Flexible interface" patented technology

The application provides a real-time conversion method for pixels and geographic latitude and longitude in low-altitude photogrammetry, which comprises the following three parts: unmanned aerial vehicle capability confirmation, real-time conversion service implementation deployment for pixels and geographic latitude and longitude in low-altitude photogrammetry, and GIS geographic information platform integration docking. Through real-time data collected by an unmanned aerial vehicle, combined with a computer vision algorithm and a spatial geometric transformation model, the specific pixel points in image data are associated with real geographic coordinates, so that accurate positioning and measurement of ground objects are realized. The application relates to the technical field of low-altitude photogrammetry, and through the cooperative work of real-time data collection by an unmanned aerial vehicle, real-time conversion service for pixels and geographic latitude and longitude in low-altitude photogrammetry, and a GIS geographic information platform, efficient mapping from a photographed image to a geographic coordinate is realized, and accurate and rapid technical support is provided for low-altitude photogrammetry.

The utility model relates to the technical field of agricultural mechanical equipment, in particular to a tractor stepless speed change transmission system which comprises an engine, a clutch is arranged at the output end of the engine, a first front speed increasing box is arranged at the output end of the clutch, a first hydrostatic stepless speed changer is arranged at the output end of the first front speed increasing box, and a second hydrostatic stepless speed changer is arranged at the output end of the second front speed increasing box. A gearbox assembly, a middle power output assembly and a rear power output assembly are arranged at the output end of the first hydrostatic stepless transmission. The front speed increasing box I and the hydrostatic stepless speed changer I are arranged, the front speed increasing box I achieves power speed increasing through gear meshing transmission, the structure is compact, the transmission efficiency is high, power input with the higher rotating speed can be provided for follow-up transmission parts, and the power transmission performance of the whole transmission system is optimized; the first hydrostatic stepless speed changer can flexibly adjust the angle of an internal swash plate according to operation requirements, and stepless speed change is achieved.
