Problems solved by technology

Patent No. ZL200820079033.X is a three-dimensional terrain measuring device based on GPS and laser technology. GPS is used to measure the latitude and longitude of a certain point in the farmland, and laser technology is used to measure the height of the point. However, this measurement method has a large workload and low efficiency.
Publication No. CN101000233A The underwater three-dimensional topographic measurement system discloses a method of measuring the sand wave shape of the underwater bed surface in the tank by using image technology, but it is only applicable to the laboratory

Abstract

The invention discloses a vehicle-mounted farm three-dimensional topographical surveying device which comprises a GPS (global position system) receiver, a GPS aerial, an AHRS (attitude and heading reference system) attitude sensor, an absolute encoder, a data collector and a flat shovel of a land scraper. The vehicle-mounted farm three-dimensional topographical surveying device disclosed by the invention has the advantages of high measuring accuracy, high operating efficiency and simpleness in operation, and can be used for precise measurement of three-dimensional topography of dry lands and paddy fields.

Description

technical field [0001] The invention relates to the field of three-dimensional topographical measurement of farmland, in particular to a vehicle-mounted three-dimensional topographical measurement device for farmland. Background technique [0002] In agriculture, in order to effectively improve the condition of the field, improve the irrigation efficiency and uniformity of the field, it is necessary to finely level the land. At present, conventional land leveling technology, laser control leveling technology and GPS leveling technology are widely used at home and abroad. The leveling datums of these leveling techniques are mostly determined subjectively by the operator. At present, there are few researches on the three-dimensional topographic measurement technology of farmland in China. Patent No. ZL200820079033.X's 3D topographic measuring device based on GPS and laser technology uses GPS to measure the latitude and longitude of a certain point in the farmland, and uses l...
