Miss-planting rate detection method of rice transplanter

Abstract

The invention discloses a miss-planting rate detection method of a rice transplanter, which comprises the following steps that: (1) an image collection module acquires a rice seedling bed color imageand transmits the rice seedling bed color image to an image processing and analyzing module; (2) the image processing and analyzing module processes the rice seedling bed color image to obtain an optimized rice seedling binary image and obtain a rice seedling communication area; (3) accumulating the white pixel values of each row and each column of the optimized seedling binary image by using a pixel projection method, determining left and right boundaries and upper and lower boundaries of an expected target area, and segmenting the optimized seedling binary image into a plurality of target area units; (4) after the image processing and analyzing module continuously processes a plurality of images, counting the number of blank target area units and the number of all target area units; and(5) calculating the proportion of the number of the blank target area units in the number of all the target area units to obtain the miss-insertion rate. The miss-planting rate of the rice transplanter is accurately detected, the detection effect is good, the speed is high, and the cost is low.

Description

technical field [0001] The invention relates to an agricultural detection method, in particular to a detection method for a rice transplanter's missing insertion rate. Background technique [0002] Hybrid rice is a high-quality and high-yield rice that has been widely used in China and Southeast Asia. Rice culture believes that uniform canopy uniformity can promote the rational distribution of ecological factors such as water, fertilizer, light and heat, so as to obtain higher harvest yield. Hybrid rice emphasizes fewer roots and strong seedlings, so as to fully develop the individual production potential of hybrid rice, optimize the population structure and improve the quality of rice population. Due to the strong tillering ability, the existing hybrid rice plants generally require 2-3 seedlings to be planted in each hole, while the super hybrid rice requires 1-2 seedlings to be planted in each hole. When the rice transplanter is transplanting, the amount of seedlings tak...

However, the traditional inspection of missing insertion rate is obtained through field manual investigation. This investigation method is not only labor-intensive and time-consuming, but also human error is inevitable.
