Three-dimensional reconstruction and measurement device and method of greenhouse strawberry canopy

Abstract

The invention relates to a three-dimensional reconstruction and measurement device and a three-dimensional reconstruction and measurement method of a greenhouse strawberry canopy. The three-dimensional reconstruction and measurement device comprises a walking mechanism, wherein the walking mechanism is arranged on a truss of a greenhouse, a control end of the walking mechanism is connected with one output end of an electric control box, and an input end of the electric control box is connected with an ultrasonic sensor group; the other output end of the electric control box is connected with an upper computer, and the ultrasonic sensor group is used for transmitting collected three-dimensional coordinate data of canopy contour points of a greenhouse strawberry plant to the upper computer through the electric control box, so as to perform data processing; and the electric control box is composed of a motor control module and an MCU (Micro Control Unit) main control panel, wherein an output end of the MCU main control panel is respectively connected with the motor control module, the ultrasonic sensor group and the upper computer, the MCU main control panel interacts information with the ultrasonic sensor group and the upper computer, working commands are sent to all components by the MCU main control panel, and the data collected by the ultrasonic sensor group are transmitted to the upper computer. The device and the method have the advantage of higher measurement precision, the requirements of automatic drug spray, precise fertilizer application and estimation of fruit yield of the greenhouse can be satisfied, and the device and the method can be widely applied to the field of modern agricultural equipment and computer measurement and control.

Description

technical field [0001] The invention relates to a greenhouse strawberry canopy measurement device and method, in particular to a greenhouse strawberry canopy three-dimensional reconstruction and measurement device and method used in the fields of modern agricultural equipment and computer measurement and control.

Problems solved by technology

At the same time, the rapid development of strawberry planting in greenhouses has greatly enhanced the demand for new technologies in facility agriculture, and the three-dimensional reconstruction and measurement of strawberry canopy plays an important role in the precise management of strawberry in greenhouses such as automated pesticide application, precise fertilizer application, and fruit yield estimation. It has important research significance, but due to the irregularity and complexity of the shape of the greenhouse strawberry canopy, conventional methods cannot effectively measure the canopy of plants

The current measurement methods are manual measurement or visual estimation, and the measured value deviates greatly from the actual value, and its measurement accuracy cannot meet the requirements of automatic pesticide application in greenhouses, precise fertilizer application and fruit yield estimation, and consumes a lot of manpower and material resources.
