Abstract

A farmland image acquisition device belongs to the technical field of agricultural machinery. In the present invention, a camera is installed on the industrial camera, and a scanning window is provided on the laser radar scanner. The included angle between the axis directions is to adapt to or compensate for changes in natural light. The industrial camera is fixed to the upper end of the lidar scanner, the pose adjustment device is fixed to the lower end of the lidar scanner, and the lower end of the motor III in the pose adjustment device It is fixedly connected to the center of the upper tray I of the upper bracket in the vibration-absorbing support bracket imitating the human knee joint; the invention can be mounted on any agricultural machinery and equipment to realize the collection of farmland images and determine the relative position information of objects in the images at the same time , in the process of farmland image collection, the present invention can reduce the adverse interference of ambient light, farmland dust, ground undulations, agricultural machinery walking and engine vibration on image collection quality.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a farmland image acquisition device serving farmland machine vision technology. Background technique [0002] At present, more and more agricultural machinery and equipment are applied to machine vision technology, such as using machine vision technology to obtain the number of ears of corn in the field, so as to calculate the corn yield. With the number of corn ears harvested by the corn harvester and the total number of corn ears in the field, the ear loss rate of the corn harvester, etc. are obtained. Obtaining high-quality farmland images is a key step in applying machine vision technology to solve practical problems. [0003] Under the farmland operation environment, practical problems such as changing light, high dust content, undulating ground, walking of agricultural machinery and engine vibration and shock have caused great obstacles to the co...
