Abstract

The invention discloses a reverse weed positioning method and a reverse weed positioning device, which are used for positioning field weeds for a crop. The reverse weed positioning method comprises the steps of: crop positioning, a field crop is analyzed and recognized according to feature values of an extended HU invariant moment of the crop and shape features of the crop through analyzing image information of the crop, and a crop region is marked, wherein the shape features comprises vertical and horizontal axis ratio, rectangular degree, area concave-convex ratio, perimeter concave-convex ratio, spherical property, circularity, eccentricity ratio and shape parameter features; weeds positioning, wherein all green plants outside the crop region are regarded as weeds, and the region outside the crop region is marked as a weed region; and result output, wherein the crop region and / or weed region are / is output and displayed. The reverse weed positioning device comprises an image acquisition module, an image processing module, a data processing module, a positioning and marking module, and an output and display module. The reverse weed positioning method and the reverse weed positioning device can automatically acquire field weed information quickly and accurately, and achieve precise positioning of the weeds.

Description

Technical field [0001] The invention relates to a weed positioning technology, in particular to a reverse weed positioning method and a positioning device for positioning crops and then weeds. Background technique [0002] Farmland weeds are the enemy of agricultural production and one of the basic problems that plague the growth of crops. Therefore, how to automatically obtain farmland weed information quickly and accurately has become the primary problem faced by precise weed control technology, and it is also a bottleneck restricting its realization. Although there are many researches on weed identification, it is very difficult to accurately locate and identify each weed due to the large number of weeds in the field. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a reverse weed positioning method and positioning device for the above-mentioned problems of the prior art, which can automatically analyze and identify fi...
