Problems solved by technology

Therefore, the device is only suitable for measuring the height of the crops directly below the sensor, and because the ultrasonic ranging sensor itself has some shortcomings, such as reflection problems, noise, crossing problems, etc., it will bring great influence to the determination of the top of the crop canopy. errors, which in turn affect the results of height measurements

Abstract

The invention discloses an automatic height measurement device for crops. The device is used for automatic measurement of crop height. The device comprises a pedestal, a transmission part, a sensing part, a control part and a display part; the transmission part, the sensing part, the control part and the display part are arranged on the pedestal; the control part sends instructions to control the operation of the transmission part and drives the sensing part to scan and measure the crops so as to acquire measurement data, and the sensing part returns the measurement data to the control part; and the control part calculates and processes the returned measurement data to acquire the crop height, and outputs the crop height to the display part to display. The device can accurately determine the canopy tops of the crops at the same time of ensuring low hardware cost and finish automatic measurement of the crop height.

Description

technical field [0001] The invention relates to a measuring device in the field of agricultural meteorological observation, in particular to an automatic height measuring device for crops. Background technique [0002] In the field of agricultural meteorological observation, plant growth height is one of the symbols to measure the growth rate of crops. Currently, during the entire growth period of the crops, the height of the crops is measured manually. This method is not only cumbersome to operate and imposes a heavy burden on observers, but also introduces human errors into the measurement results. [0003] Patent document 200810059040.8 discloses a method for detecting the plant height of crops. The photoelectric scanning system is used to continuously scan the crops, and the state of the optical receiver is scanned from top to bottom to extract the edge height data of the current position of the plant. This method is more suitable for crop mechanization operations, suc...
