Abstract
The present invention is provided with a named self-adapting complementary color light source, and belongs to the electrooptical technology field. The present invention provides a novel method which can quickly transform the colour spectrum of the light source to obtain the best complementary color spectrum according to the character of lighting objects, and effectively solve the best complementary color light source problem in the field of machinery vision identifying. Under the condition that a hardware structure does not be changed, the best complementary color effect can be obtained fast according to the special lighting object, thereby greatly improving the precision for identifying. When a light source for lighting illumine an object, an image can be obtained through a CCD camera, the images are distinguished, and light having best effect is chosen through a complementary color analytical system.
Description
(1), technical field:
The present invention is intended to solve in the Machine Vision Recognition field, and a kind of method at the best complementary color effect of the fast automatic selection of concrete testee light source belongs to field of photoelectric technology.
(2), background technology:
In up-to-date technology, the complementary color principle in order to strengthen the testee characteristic information, is adopted in the Machine Vision Recognition field, and the wavelength of lighting source is chosen.In order to achieve the above object, there is technological means also can only in limited several colour light sources, choose, do not reach best complementary color effect.To change different measurands, characteristic information in addition thereupon.Require the color characteristic of lighting source to change thereupon, be difficult to realize with existing technical method, particularly on the production line that runs up, measure the necessary frequent exchange light source of accurate data demand, this does not accomplish.
(3), summary of the invention:
The present invention proposes a kind of new method, realizes that according to lighting object, converted light source obtains best complementary color spectrum fast, solves above existing problem effectively.
Technical solution of the present invention is: can synthesize the principle of any color of light based on primaries, select the illumination light color to reach best complementary color effect automatically based on the complementary color principle.This process is finished automatically.
Each light source cell constitutes by containing three primary colors (as red, blue, Huang) illuminator.But by the versicolor light of primaries furnishing, we can obtain versicolor light, select best complementary colour light source to become possibility thereby can make.
When toning light source irradiating object, obtain image through the complementary color analytic system by the CCD camera, image is analyzed selected light source with best complementary color effect.This to objectives, the light source that automatic generation (finding) has best complementary color effect is referred to as " self-adapting complementary colour light source ".The present invention has also comprised the structure light source with self-adapting complementary colour light source array structure different shape.
The self-adaptation light source under the constant situation of hardware configuration, can obtain best complementary colour light source fast according to specific measurand, has greatly improved analysis precision, and this is that fixed light source (have only limited several, and be lack of consistency) is incomparable.
