Embodiment 1

[0051] Such as image 3 In the shown present embodiment, 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 with a radius of A, and it is judged to be in a non-lodging state.

Abstract

The invention discloses a real-time detection system and detection method for planting quality in dry land. An industrial camera and a distance sensor are fixed on a planting row frame of a transplanting machine and are always kept 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 image is processed and analyzed. Using the real-time distance between the camera and the ground obtained by the distance sensor, the precise plant distance between the geometric centroids of the rice seedling leaves is calculated. By comparing the geometric centroid distance of the rice seedling leaves with the theoretical distance The distance between centers can be used to determine planting quality indicators such as seedling holes, lodging and exposed seedlings. The invention reduces the cost and the difficulty of detection and judgment, improves the processing speed and precision, provides real-time detection of exposed seedlings, fallen seedlings and missing seedlings for the transplanting operation quality of the dry land transplanter, improves the operation efficiency of the transplanter and reduces manual use cost.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a detection method for a real-time detection system 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 ...
