Abstract

The invention discloses a detection method and device of a planting seedling plant spacing and a hole seedling number of a rice transplanter. The method includes the steps: continually detecting working states and driving speed of the rice transplanter by a detecting and starting module; beginning to shoot a working area of the rice transplanter by a camera in real time when the rice transplanteris in a planting state; performing graying and binarization on RGB (red, green and blue) images of seedlings acquired by an embedded controller; extracting profile images of the seedlings, and calculating the planting seedling plant spacing and the hole seedling number of the rice transplanter according to a profile sudden change degree algorithm; broadcasting a current seedling plant spacing anda current hole seedling number by a voice reminding module; timely adjusting and controlling working parameters of the rice transplanter by a planting driver according to fed back information. Compared with the prior art, according to the technical scheme, the planting quality of the rice transplanter is automatically detected, and field working stability and field working reliability of the ricetransplanter are ensured.

Description

technical field [0001] The invention relates to the technical field of intelligent control of agricultural equipment, in particular to a method and a device for detecting the distance between rows of transplanted seedlings and the number of seedlings in holes of a rice transplanter. Background technique [0002] In agricultural production, the premise of high rice yield is high-quality population, and good rice individuals are the skeleton of super-high-yield population and the basis for improving quality. The spacing between rice seedlings and the number of seedlings in holes directly affect the light-receiving posture of individual seedlings in the field and the light distribution in the canopy, which in turn affects the photosynthesis of rice seedling populations. [0003] In order to achieve the goal of high rice yield, in addition to improving the quality of seedling raising, it is more important to realize the automatic detection of the performance of the rice transpla...
