AI Technical Summary

Technical Problem

Existing plant protection vehicles cannot adjust according to the growth status of fruit trees when fertilizing, resulting in uneven fertilizer usage, resulting in waste and increased planting costs. The traditional path generation method is complex and has limited scope of application, so it cannot adapt to the planting of fruit trees in mountainous hilly areas.

Method used

Using a method based on remote sensing technology, the orchard images are obtained through drones, the NDVI index is calculated and the fruit tree canopy layer is extracted, the trajectory line of the fruit tree row is fitted, and the driving path with fertilization information is generated to realize variable fertilization.

Benefits of technology

Variable fertilization is implemented according to the growth status of fruit trees, which reduces fertilizer waste, reduces planting costs, and simplifies the path planning process, which is suitable for various fruit tree planting methods.

Abstract

The invention discloses an orchard unmanned plant protection vehicle variable fertilization path generation method based on a remote sensing technology. The method comprises the following steps: S1, data acquisition and processing; s2, calculating an NDVI index and extracting a fruit tree canopy; s3, extracting a centroid point; s4, centroid point fitting; s5, calculating line-to-line trajectories of the fruit trees; s6, generating a turning track; s7, calculating the ViDPT index of the vegetation index density of each tree; s8, calculating a fertilization prescription map of each tree; s9, generating a driving path with fertilization information; and S10, uploading the driving path with the fertilization information to a plant protection vehicle to realize variable rate fertilization. According to the invention, setting work can be rapidly completed for the plant protection vehicle, the orchard plant protection vehicle operation path planning can be rapidly completed by using the unmanned aerial vehicle to shoot the orchard once, tedious process setting is omitted, and manpower and time are saved. Based on the path generation method, variable fertilization of the plant protection vehicle according to the plant growth condition can be realized, so that the fertilizer is saved, and the planting cost is reduced.
