Three-dimensional shape monitoring device and method for greenhouse crops based on depth camera

Abstract

The invention discloses a greenhouse crop three-dimensional shape monitoring device based on a depth camera and a monitoring method thereof. A water culturing device is arranged in a monitoring mechanism bracket. A monitoring mechanism moves right above a water culturing device crop for acquiring depth data. Preprocessing, data compression and data transmission are performed in a small host computer. Combined decoding, storage, analysis and UI displaying are performed on the transmitted data in a monitoring terminal. Data storage and data analysis are performed. The extracted related parameters of the crop and environment parameters which are acquired by a sensor are input into an established crop monitoring model. An information parameter of the crop is calculated and is synchronized to Internet-of-things through a network. Furthermore the environment parameters are optimized, and correction on an environment condition is realized through a control center according to the obtained environment parameters. The device and the method are used for lossless monitoring of growth state of the greenhouse crop. Stable and accurate data acquisition and environment information model establishment can realize improvement of facilities and an agricultural process, thereby reducing cost and increasing crop output. The greenhouse crop three-dimensional shape monitoring device and the monitoring method thereof can be used for three-dimensional shape monitoring of leaf vegetable crops in the greenhouse.

Description

technical field [0001] The invention relates to agricultural crop information monitoring technology, in particular to a three-dimensional shape monitoring device and monitoring method for greenhouse crops based on a depth camera. Background technique [0002] Since the industrial revolution, the production of human material wealth has increased significantly, but at the same time, the shortage of resources, environmental pollution, food safety and other issues have become increasingly prominent. When the contradictions intensified, the Plant Factory Society of Japan proposed the concept of Plant Factory. The plant factory is a system that realizes the annual continuous production of crops through high-precision environmental control in the facility. , CO 2 The concentration and nutrient solution and other environmental conditions are automatically controlled, so that the plant growth in the facility is not or rarely restricted by natural conditions. Labor-saving production....

Problems solved by technology

[0004] The developed non-destructive monitoring of crops based on two-dimensional images has achieved the acquisition of crop growth information to a certain extent and guided the environmental control of plant factories, but it still cannot avoid the limitations of its own dimension and cannot fully obtain high robustness. High-precision, high-precision crop information
