Embodiment 1

[0038] refer to Figure 1-5 , a kind of all-round visual navigation acquisition device for agricultural machinery, comprising support plate 1, four rotating plates 6 are arranged on the top of support plate 1, and the tops of four rotating plates 6 are all fixedly installed with CCD camera 100, illuminating lamp 101 and infrared measuring device. From the module 102, the bottom of the rotating plate 6 is hinged with a pole 7 whose bottom end is fixedly connected to the top of the support plate 1. A U-shaped seat 2 is arranged below the support plate 1. The bottom of the U-shaped seat 2 is fixedly connected with a base plate 3. The base plate The top of the U-shaped seat 2 is fixedly connected with the battery 4 located in the U-shaped seat 2, and the top of the U-shaped seat 2 is fixedly connected with a rectangular tube 5 fixedly embedded with the support plate 1, wherein the top and bottom of the support plate 1 are provided with the same Rectangular tube installation throug...

Embodiment 2

[0047] refer to Figure 6-7, on the basis of the first embodiment, the present embodiment is different from the first embodiment in that: the bottom plate 3 is also provided with a rotation adjustment mechanism, the rotation adjustment mechanism includes a fixed plate 37 arranged below the bottom plate 3, and the fixed plate 37 A round shaft 36 is fixedly connected to the top of the round shaft 36, and the top of the round shaft 36 rotates with the bottom of the bottom plate 3. The bottom of the bottom plate 3 is ring-shaped and equidistantly nested with a plurality of balls 41, and the balls 41 are in rolling contact with the top of the fixed plate 37. The first gear 38 is fixedly sleeved on the shaft 36, and the left side of the first gear 38 is meshed with a second gear 39. The top of the bottom plate 3 is fixedly installed with a brake motor 40 electrically connected to the battery 4, and the brake motor 40 The bottom end of the output shaft is fixedly connected to the top...

Abstract

The invention provides an all-dimensional agricultural machine visual navigation acquisition device. Aiming at solving the problem that an existing all-dimensional agricultural machine visual navigation acquisition device is inconvenient to shield, buffer and protect the tops of a plurality of CCD cameras, surround and protect the tops of the CCD cameras and adjust the gradients of the CCD cameras, the following scheme is proposed, the all-dimensional agricultural machine visual navigation acquisition device comprises a supporting plate, four rotating plates are arranged above the supporting plate, the top of each rotating plate is fixedly provided with a CCD camera, an illuminating lamp and an infrared distance measuring module, the bottom of each rotating plate is hinged to a supporting rod, and the bottom end of each supporting rod is fixedly connected with the top of the supporting plate. The tops of the four CCD cameras can be shielded, buffered and protected, the four CCED cameras can be surrounded and protected, four baffles can be quickly, synchronously and automatically opened during use so as to remove surrounding and shielding, the inclination angles of the four CCD cameras can be quickly adjusted according to actual needs, the orientation angles of the CCD cameras can be adjusted, the use requirements can be met, and use is facilitated.

Description

technical field [0001] The invention relates to the technical field of collection equipment, in particular to an all-round visual navigation collection device for agricultural machinery. Background technique [0002] The automatic navigation of agricultural machinery has a broad prospect. It has a wide range of applications in many aspects such as automatic spraying of pesticides, fertilization, harvesting operations, intertillage weeding, and rice transplanting. At present, the navigation research on agricultural machinery has mainly focused on machine vision and GPS navigation. In the two most promising ways, visual navigation of agricultural machinery, the navigation steps of agricultural machinery are as follows: first, preprocess the image collected by CCD, comprehensively use the weighted average method, improve the method of maximizing the variance between classes and the small area Then, to extract the navigation reference line, first define the point with the larges...
