Embodiment 1

[0051] Such as image 3 In the present embodiment shown, the seedling height is P.

[0052] Such as Figure 4 As shown, judge from top to bottom in the figure:

[0053] The actual geometric centroid position of the leaf of the first seedling is between two circles, and it is judged to be in a lodging state, but it is in an unexposed state.

[0054] At the position where the second plant should actually be planted, the geometric centroid of the leaf is located within a circle A with a radius of Psinθ, which is judged to be in a non-lodging state. .

Abstract

The invention discloses a dryland planting operation quality real-time detection system and a detection method. An industrial camera and a distance sensor are fixed on a planting row machine frame ofa transplanter and are always perpendicular to the ground, the industrial camera collects sample images of seedlings transplanted in the field in real time, combined with the distance between the camera and the ground obtained by the distance sensor, the sample images are processed and analyzed, the real-time distance between the camera and the ground is obtained by using the distance sensor, theprecise plant spacing between the geometric centroids of seedling leaves is calculated, and by comparing the distance between the geometric centroids of seedling leaves with the theoretical plant spacing center spacing, the planting quality indicators such as seedling cavities, lodging and exposed seedlings are judged. The cost and the difficulty of detection and judgment are reduced, the processing speed and precision are improved, real-time detection of exposed seedlings, lodging seedlings and missing seedlings is provided for the transplanting operation quality of dryland transplanters, theoperating efficiency of the transplanter is improved, and manual use cost is reduced.

Description

technical field [0001] The invention belongs to the field of agricultural machinery equipment, and in particular relates to a real-time detection system and detection method for transplanting operation quality of a dryland planter. Background technique [0002] The planting method of crop seedling transplanting has the advantages of high emergence rate, small amount of seeds, convenient for fine management at the seedling stage, and solving the tension of stubble connection. Planting quality problems such as inverted seedlings and exposed seedlings. At present, the existing dryland transplanting machines generally lack the planting quality detection function, resulting in the need to rely on manual continuous real-time observation of the planting effect during the transplanting operation, which seriously affects the improvement of operating efficiency. And increased labor costs. [0003] At present, there have been published patents on transplanting operation quality monito...
