A method to measure plants grown uniformity Based on ultrasonic

摘要

Ultrasonic ranging is an effective non-contact ranging method. This paper introduces a method to measure and analyze the height of each point of corps in the space utilizing ultrasonic sensor. After acquiring the uniformity measurement curves of the corps by this method, the evaluation standards of the growth state of corps can be obtained. It is of reference value to the macro-acquisition of biomass production and at the same time, it is of significance to the agricultural work of crop fertilization, selective irrigation and yield estimation.
