Description

Technical Field

[0001] The present invention specifically relates to the technical field of plant height measurement, and in particular to a device and method for high-throughput measurement of crop plant height based on infrared technology. Background Art

[0002] Plant height measurement is the measurement of crop growth height. Plant height is measured regularly to understand crop growth rate and its relationship with external meteorological conditions, and to provide data for agricultural and agricultural meteorological research and service work. The measurement time and frequency vary depending on the crop and the purpose of measurement. For example, to understand the height changes of the crop during the entire growth process, the measurement should be carried out regularly and at the general stage of each development period, starting from the emergence of seedlings to the three-leaf stage until the height stops increasing.

[0003] In the prior art, the measurement of corn plant height is generally carried out using a tape measure or a rod ruler. Since the tape measure is easy to bend and the corn plant height is high, there are problems such as great difficulty in measurement and inaccurate measurement results. Therefore, most of the plant height measurements are carried out using a rod ruler. For example, the Chinese utility model patent with application number CN201720121954.7 discloses a corn plant height stem thickness measuring ruler, which includes a first ruler, a second ruler, a fixing screw, a top alignment rod, a pedal, and a tape measure box. The second ruler is located in the first ruler and can slide along the height direction of the first ruler; the fixing screw realizes the fixing of the second ruler in the first ruler; the top alignment rod is connected to the top of the second ruler; the pedal is connected to the bottom of the first ruler; a small tape measure is placed in the tape measure box for measuring the corn stem thickness. Although this technical solution has certain advantages over tape measure measurement, it still has defects. On the one hand, this solution uses a top alignment rod to achieve top alignment, which requires that the measuring rod must be close to the corn plant. Since the corn stem has leaves that open outward, there is a certain distance between the measuring rod and the corn plant. When the distance is too large, the top alignment rod cannot be close to the top of the plant, resulting in the problem of increased difficulty in the alignment process; on the other hand, in the process of alignment using the top alignment rod, the alignment is still performed by comparison. Since the operator is a certain distance away from the top of the plant, it is inevitable that there will be errors in the line of sight during the comparison process, resulting in inaccurate measurement results; on the other hand, since the first ruler and the second ruler are in sliding cooperation, when the second ruler is pulled upward, it is always necessary to control the second ruler by hand to prevent the second ruler from falling due to gravity, which is inconvenient to operate.
