Problems solved by technology

[0005] However, in the prior art, the method of analyzing leaf water content by collecting images of plant leaves usually improves the calculation accuracy of leaf water content by increasing the pixels of image acquisition equipment or improving image processing algorithms, while ignoring the image The collection process, especially the quality of the collected images, makes the quality of the collected images unstable (that is, the image quality varies from high to low) under different environments, lighting, angles and distances, which leads to the calculation accuracy of leaf moisture content. prone to fluctuations, large deviations

Embodiment 1

[0050] see figure 1 , a plant water detection method is provided in this embodiment, by collecting images in advance, analyzing the shooting angle, and then adjusting the shooting angle to the same position as the shooting angle when shooting the leaves of the standard sample according to the needs, and then performing a formal Image acquisition specifically includes the following steps:

[0051] Step 2, using an image acquisition device to collect images of the measured plants to obtain an initial image.

[0052] That is, after confirming the target leaf to be collected, the image acquisition device is adjusted to the vicinity of the target leaf, and the target leaf is included in the field of view of the image acquisition device, and then an image is collected, which is used as an initial image, so as to determine the location of the image acquisition. The current camera angle of the device.

[0053] Step 3. Identify the image of the target leaf from the initial image.

Abstract

The invention relates to a plant moisture detection method and system. The plant moisture detection method comprises the following steps of collecting an image of a to-be-detected plant by use of image collecting equipment to obtain an initial image; identifying a target blade image from the initial image; determining a current shooting angle of the image collecting equipment according to length and width sizes of the target leaf image; adjusting the shooting angle of the image collecting equipment so that the shooting angle of the image collecting equipment is the same as a shooting angle formed by collecting a standard sample blade or is within a set angle threshold value; and collecting the image of the to-be-detected plant again by use of the image collecting equipment and obtaining the target blade containing image. With the method, the image collecting precision can be effectively improved, the high-quality image is obtained, the subsequent image processing and analysis process can be effectively simplified, the efficiency is improved and more accurate blade moisture content data are beneficially obtained.

Description

technical field [0001] The present invention relates to the technical field of water content detection, in particular to a plant water detection method and system. Background technique [0002] my country is a large agricultural country, and agricultural water consumption accounts for about 70% of the total water consumption. Among them, farmland irrigation water accounts for the largest share. At this stage, my country is vigorously developing water-saving agriculture, and precision irrigation is a major trend in the development of water-saving agriculture. The so-called precision irrigation is to irrigate the crops reasonably and effectively according to the moisture content of the crops, which can effectively avoid the waste of water resources caused by flood irrigation. [0003] In the traditional technology, the method for judging whether plants (crops) need to be irrigated is to arrange moisture content sensors in the soil, collect the moisture content in the soil throu...
