Description

Intelligent phenotype collection trolley and collection method based on high-stalk crops
Technical Field
The invention relates to the technical field of plant data acquisition, in particular to an intelligent phenotype acquisition trolley and an intelligent phenotype acquisition method based on high-stalk crops.
Background
By utilizing advanced sensors and modern information technology, the morphological structure of crops can be vividly reproduced in a three-dimensional visual mode on a computer, and the dynamic process of plant growth and the interactive relationship of plant environment can be analyzed, simulated and predicted. A common method is a multi-view image method: the method comprises the steps of acquiring a multi-angle image sequence through a camera, and acquiring a three-dimensional point cloud picture of a crop by combining data processing software, so as to acquire phenotypic parameters of the crop.
The traditional mode of acquiring plant phenotype parameters by manual measurement is relatively accurate, but wastes time and labor, is not suitable for large-scale popularization, and has the problems of poor timeliness, strong subjectivity and high cost, so the traditional mode does not meet the requirement of propelling intelligent agriculture.
At present, the most common crop phenotype parameter platforms at home and abroad can be divided into an indoor platform and an outdoor platform. The indoor environment is mainly a self-propelled plant phenotype platform of a greenhouse. The self-propelled plant phenotype platform is also called as a robot phenotype platform, can provide driving power and walking power, and can finish phenotype information acquisition operation without other power. The outdoor is mainly a vehicle-mounted plant phenotype platform. The vehicle-mounted plant phenotype platform is mainly a platform which is driven by a tractor and the like, is provided with sensors according to plant species and growth conditions, and carries other accessories (such as power equipment, a data memory and the like). Such a platform is intended to reduce costs, reduce manpower and improve work efficiency. Both improve the degree of automation and intelligence, but both have some disadvantages: 1. a phenotyping platform with a highly automated self-propelled type, although capable of traveling according to a predetermined course, is also necessary in combination with a manually controlled remote control system. For monitoring and data acquisition of crops with an oversized area, more time cost can be spent on the self-walking platform. 2. The vehicle-mounted platform carrying various sensors has certain limitation when being applied to domestic general agricultural environment. Although manpower is saved to a certain extent, automation can be improved, and the vehicle-mounted platform is generally overlarge in size and deficient in flexibility; moreover, the mounting of various sensors is a burden on the vehicle body, and a multifunctional integrated sensor is required.
