Background technology
Feed mechanism for seed testing table or seeder testing table can not be subjected to the restriction of field condition as the seed sowing device performance test equipment, simulate various operating modes, and seed sowing device performance is carried out deep test, research or evaluation.In recent years, university, scientific research institutions, the enterprise in China obtained increasingly extensive application.Particularly along with mechanization seeding technique, observation and control technology and computer technology rapid development, present feed mechanism for seed testing table adopts industrial camera to gather the drawing of seeds picture in real time, computer vision system carries out processes pixel line by line to current effective image, calculate the seed centre coordinate, distance between measurement is planted, statistics kind of the number that falls, statistical unit time kind of the number that falls generates form and performance curve.In the seeding images gatherer process, the adjustment of camera position reaches to video camera provides the high-quality illumination will directly influence the accuracy of experimental test data.What existing feed mechanism for seed testing table used is general general lighting device, the general lighting device can be at the exert an influence hot spot of accuracy of detection of image acquisition face, and light is weak, skewness, problem such as reflective, therefore directly causes gathering the problem of seed poor image quality, accuracy of detection difference.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of special lighting device for seeding images that seed picture quality is good, accuracy of detection is high of gathering is provided.
For achieving the above object, the present invention adopts following technical proposals: special lighting device for seeding images of the present invention comprises support body and the casing, the belt conveyor that are installed on the support body, and is vertically mounted on the video camera directly over the belt conveyor image acquisition face center.On the lower inside wall of casing, and be positioned at the left and right sides of belt conveyor image acquisition face, the symmetry that slopes inwardly is respectively installed array direct current lamp, and the leaning angle of these two array direct current lamps is α, this α angle is 40～50 °, and light-passing board is vertically installed in the place ahead of corresponding each array direct current lamp; These two array direct current lamps are made up of lamp plate, lamp socket, lamp holder respectively, and 8～12 lamp sockets are equidistantly arranged and are installed on the center line of lamp plate, and a lamp holder is installed on each lamp socket.
Improvement as special lighting device for seeding images of the present invention, on a pair of relative upright inner side walls of described casing, symmetry is installed two back up pads up and down respectively, on described two pairs of these two back up pads, vertically install a screw mandrel respectively, track is installed on described two screw mandrels by the setting nut level, and the slide block cooperation is installed on this track, and video camera is installed on the slide block by the video camera erecting frame.
As the preferred version of special lighting device for seeding images of the present invention, the leaning angle α of these two array direct current lamps is 45 °.The quantity of this lamp socket is 10.
After adopting technique scheme, the invention has the beneficial effects as follows:
1. be positioned at the left and right sides of belt conveyor image acquisition face, the symmetry that slopes inwardly is respectively installed array direct current lamp, and the leaning angle α of these two array direct current lamps is 45 °, and light-passing board is vertically installed in the place ahead of corresponding each array direct current lamp; 10 lamp sockets are equidistantly arranged and are installed on the center line of lamp plate, and a lamp holder is installed on each lamp socket.Effectively having overcome the general lighting device can be at the exert an influence hot spot of accuracy of detection of image acquisition face, and light is weak, skewness, problem such as reflective.Obtained the high effect of accuracy of detection.
2. because track is installed on described two screw mandrels by the setting nut level, and the slide block cooperation is installed on this track, video camera is installed on the slide block by the video camera erecting frame.Can regulate the height and the horizontal level of video camera like this according to testing requirements easily, improve collection seed picture quality.
