Abstract

The invention discloses a method and a device for measuring a herbaceous plant. The distance between a distance measuring instrument and the top end of the herbaceous plant, an angle of connecting lines which are from the ground vertical line of the distance measuring instrument to the distance measuring instrument and the top end of the herbaceous plant, the distance between the distance measuring instrument and the bottom end of the herbaceous plant and the angle of the connecting lines which are from the ground vertical line of the distance measuring instrument to the distance measuring instrument and the bottom end of the herbaceous plant are measured by the distance measuring instrument; the distances and the angles are sent to a central processing unit; and the central processing unit can calculate the height of the herbaceous plant according to the distance information and the angle information. The use of the technical proposal can rapidly and accurately carry out the nondestructive measurement of the height and the coverage of the herbaceous plant.

Description

technical field [0001] The invention relates to the technical field of automatic control measurement, in particular to a method and device for measuring herbal plants. Background technique [0002] The non-destructive measurement technology of herbaceous plant height and coverage is a technology of great concern to the majority of herdsmen and grassland workers in my country, and it is also the main content of precision agriculture. It plays a huge role in accurately measuring the height and coverage of grassland for the vast number of farmers and herdsmen in my country, and timely adjusting the number of livestock breeding according to the height and coverage of grassland, developing animal husbandry production, preventing desertification of grassland, and increasing the income of farmers and herdsmen. [0003] However, at present, the height and coverage of domestic herbaceous plants are basically measured manually with a ruler, and the coverage is measured by visual estim...
