Abstract

The invention discloses a special lighting device for seeding images, aiming at providing a special lighting device for seeding images which has good collected seed image quality and high detection precision. The special lighting device comprises a rack body, a box body, a conveyor belt and a camera, wherein the box body and the conveyor belt are arranged on the rack body, and the camera is vertically arranged right above the center of the image collecting surface of the conveyor belt; two array DC lamps are inwardly, obliquely and symmetrically arranged on the inner side wall of the lower part of the box body and at the lift side and the right side of the image collecting surface of the conveyor belt; the inner inclining angle of the two array DC lamps is alpha, and the angle alpha is 40-50 degrees; transparent boards are vertically arranged corresponding to the front of the array DC lamps; each array lamp consists of a lamp panel, a lamp holders and a lamp caps; and 8-12 lamp holders are arranged on the center line of the lamp panel at equal intervals, and each lamp holder is provided with a lamp cap. The special lighting device is suitable for providing illumination for a seedling image collecting process on the test table of a seeding device.

Description

technical field [0001] The invention belongs to agricultural machinery testing instruments and equipment, in particular to a special lighting device for seeding images used in a seeder test bench or a seeder test bench. Background technique [0002] The seed meter test bench or seeder test bench is used as the test equipment for the performance test of the seed meter, which can simulate various working conditions without being limited by field conditions, and conduct in-depth experiments, research or appraisal on the performance of the seed meter. In recent years, it has been increasingly widely used in universities, research institutes and enterprises in our country. Especially with the rapid development of mechanized seeding technology, measurement and control technology, and computer technology, the current seed meter test bench uses industrial cameras to collect seed images in real time, and the computer vision system performs pixel-by-line pixel processing on the curren...
