AI Technical Summary
In existing technologies, measuring the growth parameters of tree seedlings requires frequent equipment changes, cannot achieve synchronous measurement, and has low measurement accuracy, making it inconvenient to use, especially in complex terrain conditions.
A measuring device integrating RTK positioning, laser ranging, capacitive grating sensing, and angle measurement functions was designed. It includes a support mechanism, a measuring mechanism, and a data processor. The device enables one-stop measurement of coordinates, height, and crown width through a rotating knob and telescopic device. It is equipped with a tripod and level to ensure stability, and has a built-in data processor and display screen for real-time data processing.
It enables high-precision one-stop measurement of tree seedling coordinates, height, and crown width, improving field operation efficiency and measurement accuracy. It is suitable for large-area forest surveys and ensures data integrity and traceability.
