Embodiment Construction

[0024] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0025] The present invention is mainly composed of two parts, one part is the image collection part, that is, the measuring device of the droplet spectrum; the other part is the image processing method part.

[0026] (1) Measuring device for droplet spectrum

[0027] Such as figure 1 As shown, the measuring device of the droplet spectrum consists of a target 7, a black box 1, a fluorescent lamp 2, a camera 3, an image acquisition card 4, an information output storage device 5, and a computer group 6, and its working path is: the fog on the target 7 in the black box 1 Under the illumination of the fluorescent lamp 2, the fog droplet image is captured by the camera 3, and then the captured fog droplet image is collected by the image acquisition card 4 into the computer 6 for image processing, so as to obtain accurate fog droplet data inform...

Abstract

A device used for measuring spectrogram of fog drop is prepared as setting illumination lamp and camera shooting tube as well as target in camera bellows, connecting computer with camera shooting tube through image collection card and connecting information output-storage unit to computer. The method for processing image collected by said device to obtain parameter of fog drop is also disclosed.

Description

technical field [0001] The invention relates to the technical field of pesticide application by plant protection machinery in precision agriculture, in particular to a measuring device for a droplet spectrum. The invention also relates to an image processing method for a measuring device for a droplet spectrum. Background technique [0002] In precision spraying, the droplet size is an important factor affecting the deposition and drift of droplets, and the deposition uniformity and deposition density of droplets are important indicators for judging the spray quality. With appropriate methods for measuring droplet size, a quantitative understanding of the distribution of sprayed droplet sizes can be established. At present, there are mainly magnesium oxide plate measurement method, oil pan method, Norenberg laser particle size analysis method, and laser particle size analyzer method to measure the droplet size. Although these devices and methods can measure the droplet siz...
