Abstract

The invention relates to the technical field of agriculture, in particular to a method for obtaining the leaf surface spreading characteristics of fog drops based on a timestamp. The method includes the steps that multiple layers of leaves are arranged above a target crop through leaf bracket devices, wherein angle simulation can be performed on the multiple layers of leaves; under the control of a computer control system, top cameras move horizontally and vertically to trace the fog drops on the multiple layers of leaves from the upper position, and meanwhile side cameras conduct angle rotation to trace the fog drops on the multiple layers of leaves from the side position; the fog drops are released to start to disperse after being generated on the top layer of leaves and then roll to the other layers of leaves from top to bottom, and during the process, the top cameras and the side cameras cooperate to collect rolling information and spreading characteristic information of the fog drops, and feed the collected information back to the computer control system at the same time; the computer control system establishes a spreading model of the fog drops through database information.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for acquiring the spreading characteristics of fog droplets on leaves based on time stamps. Background technique [0002] The development of agriculture largely depends on the advancement of equipment. Precision agriculture combines informatization with agriculture, realizing a qualitative leap in the agricultural development model and giving wings to the rapid development and application of agricultural technology. Plant protection is an important part of precision agriculture. The research on plant protection technology is currently mostly the testing of medical equipment. There is relatively little research on the performance of spray droplets on crops. The traditional method is mainly manual operation and then observation under an electron microscope, which cannot realize the research on the spread of spray droplets. In-depth and meticulous, it is not conducive...
