Abstract
The utility model provides a pseudo-color sees piece lamp device, mainly includes host computer, camera bracket, film observation screen, pseudo-color display screen, characterized by: the camera shoots the film gray level image displayed by the film observation screen, the film gray level image is processed by a computer image processing system arranged in the host computer and converted into a pseudo color image, and the pseudo color image is displayed in real time by a pseudo color display screen. The utility model has the beneficial effects that: because the mode of observing the pseudo color image is added on the basis of the traditional mode of observing the gray level image of the radiographic film, the image resolution capability of the film appraiser can be effectively improved, and the film appraising level of the film appraiser is further improved.
Description
Technical Field
The utility model relates to a pseudo-color film viewing lamp device, in particular to a radiographic film viewing device in the field of medical and industrial nondestructive testing.
Background
The film viewing lamp is generally applied to the medical and industrial nondestructive testing field and is used as light source equipment for viewing various radiographic film images. The light emitting elements of the traditional film viewing lamp generally adopt a fluorescent tube array, and are gradually replaced by an LED lamp array in recent years, and the light sources of the film viewing lamp and the like generally adopt positive white light or warm white light. Since the radiographic film image is essentially the optical density image of the radiation formed on the film, after the light source of the film viewer transmits, the image can only directly produce a gray scale image.
Due to the characteristics of human vision, the resolving power of the gray-scale image is far smaller than that of the color image. Therefore, different film evaluators often have different judgment results on the radiographic film due to observation differences.
In view of the above, there is a need to improve the traditional radiographic film gray scale image viewing manner to assist the film assessor in improving the level of viewing analysis of the image.
Disclosure of Invention
In order to solve the above problems, the present invention provides a pseudo-color film viewer, which aims to provide a device capable of assisting in improving the viewing ability of film viewers.
In order to achieve the above object, the present invention provides a pseudo color film viewer device, which is realized by: mainly include host computer 5, camera 1, make a video recording support 2, film observation screen 3, pseudo-color display screen 4, characterized by: the film gray level image displayed by the film observation screen 3 is shot through the camera 1, and the film gray level image is processed by a computer arranged in the host computer and is converted into a pseudo color image which is then displayed in real time through the pseudo color display screen 4.
As shown in fig. 1, the lower end of the camera bracket 2 is fixed at the center of the front end of the upper surface of the main frame 5, and the fixing mode can be a welding mode. Camera 1 is equipped with to the front end of 2 upper ends crossbeams of support of making a video recording, and support 2 of making a video recording adopts inside hollow structure to lay camera 1's power cord and data line. The camera 1 is aimed downward at the geometric center of the film viewing screen 3, so as to take a gray scale image of the film viewing screen 3. The pseudo color display screen 4 is a touch screen to facilitate control of the image processing system.
An image processing system in the host 5 firstly performs size recognition on the image acquired by the camera 1, performs image cutting, and then converts the image into a set pseudo color RGB parameter value according to the pixel gray value of the gray image to realize the conversion from the gray image to the pseudo color image. In addition, in order to adapt to habits of different film evaluating personnel, the hue, the saturation and the brightness of the pseudo color image can be manually adjusted, the pseudo color image can be zoomed, and the size information of the pseudo color image can be displayed.
The pseudo-color film viewer provided by the utility model has the following beneficial effects: because the mode of observing the pseudo color image is added on the basis of the traditional mode of observing the gray level image of the radiographic film, the image resolution capability of film evaluators is effectively improved, and the film evaluation level of the film evaluators is further improved.
Drawings
The present invention is described in further detail below with reference to the attached drawings.
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the lower end of the camera bracket 2 is fixed at the center of the front end of the upper surface of the main frame 5, and the fixing mode can be a welding mode. Camera 1 is equipped with to the front end of 2 upper ends crossbeams of support of making a video recording, and support 2 of making a video recording adopts inside hollow structure to lay camera 1's power cord and data line. The camera 1 is aimed downward at the geometric center of the film viewing screen 3, so as to take a gray scale image of the film viewing screen 3. The pseudo color display screen 4 is a touch screen to facilitate control of the image processing system.
An image processing system in the host 5 firstly performs size recognition on the image acquired by the camera 1, performs image cutting, and then converts the image into a set pseudo color RGB parameter value according to the pixel gray value of the gray image to realize the conversion from the gray image to the pseudo color image. In addition, in order to adapt to habits of different film evaluating personnel, the hue, the saturation and the brightness of the pseudo color image can be manually adjusted, the pseudo color image can be zoomed, and the size information of the pseudo color image can be displayed.
The working principle and the working process of the utility model are as follows: after the ray film evaluating personnel turn on the power of the host computer 5, the ray film to be evaluated is placed at a proper position of the film observation screen 3, and the corresponding pseudo color image can be synchronously displayed by the pseudo color display screen 4. If the film position needs to be adjusted by the film evaluating personnel, the film position can be adjusted like a traditional film viewing lamp. If the person evaluating the film wants to set the hue, saturation, brightness and scaling size of the pseudo color image by himself, the setting can be carried out through the virtual keys of the touch screen of the image processing system.
