Embodiment Construction

[0067] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, which should not be construed as a limitation of the present invention;

[0068] according to figure 1 , figure 2 and image 3 As shown, images are the visual basis for human perception of the world. However, in the large amount of image information that humans obtain through vision, not all information content is what we need, so it is necessary to divide images into several specific and unique properties. Area. Image segmentation is to divide the image into several specific regions with unique properties and extract the target of interest. For the shadowless lamp, it is necessary to find the position and area of ​​the occluder that causes the shadow, and then perform effective segmentation to obtain the characteristic information of the occluder. Reasonable segmentation results can better find useful information in the image and facilitat...

Abstract

The invention discloses an LED surgical shadowless lamp system with a full-automatic intelligent constant-light control function. The LED surgical shadowless lamp system has the advantages that video images of illuminated regions can be acquired by the aid of a CMOS (complementary metal-oxide semiconductor) camera of the system and then are subjected to noise reduction and enhancement processing by the aid of an image preprocessing module, processed data are transmitted into a video frame image storage unit to be stored in the video frame image storage unit, then the video images are blurred, brightness information of illumination regions and color information of illuminated objects are acquired by the aid of an image processing algorithm, shielding objects in the images are divided and processed in real time, and shadow regions formed by the shielding objects are acquired; an intelligent controller calculates driving current values of required-to-be-adjusted LED light sources via a fuzzy neural network according to the acquired information after processing procedures are completed, the information is further transmitted to an LED constant-current driver, the brightness and the color temperatures of corresponding LEDs can be regulated, accordingly, shadow can be eliminated, and the illumination regions are uniform and constant in illumination.

Description

technical field [0001] The invention relates to a special medical lighting equipment, in particular to a fully automatic intelligent constant light control LED operation shadowless lamp system. Background technique [0002] Surgical shadowless lamp is an important special surgical lighting equipment in the operating room of the hospital. Therefore, the improvement of the main performance indicators and functional characteristics of the surgical shadowless lamp is very important to improve the success rate and efficiency of the operation. According to various types of shadowless lamps used in long-term clinical applications in medical institutions, we can divide the development of shadowless lamps into three stages according to light source and performance: [0003] The first stage, also known as "the first generation of surgical shadowless lamps", is the era of surgical shadowless lamps using traditional halogen bulbs and xenon bulbs as light sources, that is, the era of the...
