Three-dimensional image detection system used for indoor quick seed test of maize ears

Abstract

The invention relates to a three-dimensional image detection system for rapid indoor seed testing of corn ears. Under the control of a programmable controller, the corn ears are horizontally sorted and transported after the multi-layer messy corn ears are single-layered and horizontalized, and then transmitted To the corn ear free-fall diversion channel, the corn ear free-fall diversion channel makes the corn ear enter the corn ear panoramic image acquisition platform in a free-fall movement mode. After being detected by the photoelectric switch, the programmable controller triggers the computer through the serial communication to realize the corn The panoramic image of the ear is collected, and the corn ear is detected by the method of image processing. The present invention combines programmable controller technology, electromechanical transmission technology, seed testing technology and image processing technology to realize the panoramic image acquisition of corn ears, and detect corn ears through the image processing method, with fast processing speed and high detection accuracy , suitable for the optimization of a large number of reserved corn ears for further indoor seed testing.

Description

technical field [0001] The invention relates to the technical field of three-dimensional image detection, in particular to a three-dimensional image detection system for rapid indoor seed testing of corn ears. Background technique [0002] Corn is one of the main food crops in my country, and it has attracted much attention in the food, feed and other industries. In 2010, the total national corn output was 180 million tons. With the economic and social development and the shrinking of cultivated land year by year, there is an urgent need to further increase the corn output. [0003] Due to the variety, cultivation conditions, yield level and natural climate of corn yield, the compositional factors affecting yield are also very different. Through the indoor test of corn ears, it is used to analyze and study the reasonable yield structure under different conditions. Under high-yield conditions, to strive for large ears and high grain weight is the way to further promote high-...

Problems solved by technology

[0005] Traditional manual seed testing is to use manual measurement of corn ear data. The disadvantages are: time-consuming and labor-intensive, easy to cause manual errors, low productivity and large labor costs

[0006] Semi-manual testing is to use manual to complete the placement of corn ears. Most of them use image processing methods to extract the characteristic parameters of corn ears. Limited by manual operation time
