Device and method for field measurement of plant height

Abstract

The present invention provides a plant height field measurement device and method. The plant height field measurement device comprises a truss sliding module connected with a truss, a camera arranged on the truss sliding module, an elevating guide pillar of which one end is connected with the truss sliding module, an elevating motor arranged on the truss sliding module, a plant height measurement module which is connected with the elevating motor via a transmission rope and in which the elevating guide pillar penetrates and is arranged. The beneficial effects of the present invention are that: 1, an adjustable clamping mechanism is used, can gather together the plants adaptively, and can keep the plants to be vertical; 2, two photoelectric sensors are used to determine an adjustment position and an ending position respectively, cooperate with a CCD imaging system, and adjust the plant positions at the optimal measurement states automatically; 3, the truss drives the plant height measurement module to measure in the field, thereby being able to measure the heights of batch plants; 4, the measurement is high in precision and efficiency, the operation is simple, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of agricultural instruments, in particular to an automatic measuring device and method for field plant height. Background technique [0002] Plant height is an important indicator of crop growth. On the one hand, field managers need to grasp the growth status of plants in a timely and accurate manner, and take appropriate measures to ensure the healthy growth of plants. On the other hand, in the process of crop breeding, it is necessary to obtain phenotypic information such as plant height and link it with genetic information to provide a reference for breeding crops with significantly superior phenotypes. [0003] At present, the measurement method of plant height is mostly manual measurement. Measuring tools mainly include straight scales, folding tapes, etc. The measurement process is cumbersome, inconvenient to carry, and inefficient. Especially when the height of the plant is higher than the height ...

Problems solved by technology

However, most of these systems are aimed at potted plants and work in a structured environment in the laboratory. They are not real field measurements. They are expensive and difficult to promote on a large scale.
