Plant growth recognition method and system

Abstract

The invention relates to a plant growth recognition method and a system thereof, at least one shooting unit transmits a shooting picture to a control unit so as to calculate a pixel distance per unit, then the shooting unit carries out plant shooting, and the control unit identifies characteristic points such as buds, flowers or fruits of a plant in the shooting picture so as to identify the plant growth. The control unit calculates the pixel distance and the height of each feature point, counts the number and the region of the plurality of feature points to calculate the growth rate and the yield of the plant, and updates the data such as the growth height, the growth rate and the yield of the plant at regular time to dynamically modulate the illumination intensity of the illumination unit on the plant, so that the plant growth speed and the plant yield are improved. According to the design of the automatic plant growth recognition system, the effects of effectively saving labor cost and lighting energy consumption, improving plant yield and quality and the like are achieved.

Description

Technical field [0001] The present invention relates to a plant growth identification method and system, particularly an automated plant culture to effectively save human cost, lighting energy consumption, and improve plant yield and quality. Background technique [0002] According to the cultivation of plants, the cultivation of plants is affected by natural environment and climate, etc. Gradient attention. [0003] Since the amount of light volume affects the significant factors of plant growth, general greenhouse cultivation and indoor cultivation will use the artificial light source to imitate the sun irradiation effect, with the intensive plants, and the distance between the artificial light source and the plant will directly affect the distance between the artificial light source and the plant. To the photosynthesis of the plant, if the distance from the plant is too large, the light intensity is insufficient, and the photosynthesis of the plant will reduce the photosynthes...

AI Technical Summary

Problems solved by technology

[0003] Since the amount of light is one of the major factors affecting plant growth, artificial light sources are often used in greenhouse cultivation and indoor cultivation to imitate the effect of sunlight and facilitate photosynthesis of plants, and the distance between artificial light sources and plants will directly affect For the photosynthesis of plants, if the distance between the light source and plants is too large, the light intensity will be insufficient, which will reduce the photosynthesis of plants. On the contrary, if the distance between the light source and plants is too small, the light intensity will increase, which will also affect the growth of plants and cause adversity.

However, the adjustment of the light intensity and irradiation time of the existing artificial light source still relies on human experience to judge. In addition to being unable to accurately control and easily causing improper energy consumption, it is necessary to go to the greenhouse every day to take care of each plant to adjust the light suitable for its growth. Conditions, also need to consume a lot of manpower and time, resulting in waste of labor costs and working hours

In addition, the harvesting time and yield of plants can only be estimated by manual experience, so the problem of inaccurate harvesting estimation is prone to occur. When the harvesting estimation is inaccurate, the quality and yield will be affected, resulting in a decline in economic value or improper fluctuations in market prices. , affecting the income of farmers and the development of market economy
