Problems solved by technology

[0003] The participation of many research institutions and manufacturers has made the research, promotion and application of automatic navigation driving technology for agricultural machinery in my country more and more popular. Accuracy varies
However, at present, there is no uniform and standardized method for evaluating the accuracy of automatic navigation operations in agriculture. Therefore, when users purchase agricultural machinery automatic navigation products, they cannot accurately judge whether the operation quality of the purchased products meets the production requirements.

Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with specific embodiments.

[0028] A method for checking the accuracy of the automatic navigation path of a rice transplanter by using a total station, comprising the steps of:

[0029] S101, the total station is fixed on the edge of the field, and the automatic navigation rice transplanter automatically drives in the field after planning the path. In step S101, the setting of the automatic navigation planning path of the rice transplanter is as follows: when the GPS signal is good, set points A, B and the row spacing, and the automatic navigation system automatically generates a navigation path. The generated navigation path includes multiple straight-line paths and semi-arc paths connecting adjacent straight-line paths; each straight-line path is parallel to each other, the distance between adjacent straight-line paths is equal to the line spacing, and the diameter of the semi-arc path is ...

Abstract

The invention relates to a method for detecting the accuracy of an automatic navigation path of a transplanter via a total station instrument. After that the transplanter carries out automatic navigated transplanting, the total station instrument measures positions of seedlings, the seedling path in the coordinate system of the total station instrument is obtained, navigation data is converted into navigation path in the coordinate system of the total station instrument by coordinate transformation, and the navigation paths is compared with the seedling path to detect the accuracy. The total station instrument is high in precision and therefore can ensure the accuracy of the seedling path, the navigation path can be detected via the method, and the navigation quality can be further improved. The invention relates to automatic navigation test technologies of farm machinery.

Description

technical field [0001] The invention relates to an agricultural machinery automatic navigation inspection technology, in particular to a method for inspecting the accuracy of an automatic navigation path of a rice transplanter by using a total station. Background technique [0002] Driven by precision agricultural technology, agricultural automatic navigation technology has developed rapidly and is widely used in various agricultural fields to improve operational efficiency and reduce labor costs. [0003] The participation of many research institutions and manufacturers has made the research, promotion and application of automatic navigation driving technology for agricultural machinery in my country more and more popular. Accuracy varies. However, at present, there is no uniform and standardized method for evaluating the accuracy of automatic navigation operations in agriculture. Therefore, when users purchase agricultural machinery automatic navigation products, they cann...
