Description

Technical Field [0001] The present invention relates to a three-dimensional facial image acquisition system and an illuminating device applied thereto,

The present invention relates to a three-dimensional face image acquisition system, and more particularly, to a three-dimensional face image acquisition system capable of more easily providing an illumination environment suitable for acquiring a desired three-dimensional face image through scanning or camera shooting, And a lighting device.

Generally, in order to correct or treat a tooth in a dental clinic, a tooth model composed of a gypsum corresponding to a patient's tooth is produced.

At this time, the tooth model is converted into digital data through a scanning operation using a three-dimensional scanner, and is stored and utilized. That is, the tooth model can analyze, store and store the data necessary for the treatment of a specific tooth more conveniently and accurately through the dental model analysis implemented through the dental three-dimensional scanner.

On the other hand, Orthodontic Treatment is a procedure for improving the dentition such as malocclusion through the movement of the dentition. The orthognathic surgery is performed to perform skeletal improvement by performing surgical operation on the jaw, And the facial and head of the patient can be extracted as three-dimensional shape data for orthognathic surgery, jaw fracture surgery, or surgical facial cosmetic surgery.

In order to achieve this, a three-dimensional face image is acquired through a recent 3D scanner or camera shooting (see FIGS. 1 and 2).

However, in the past, it was not easy to adjust the lighting according to the desired shooting conditions in the scanning or camera shooting for acquiring the three-dimensional face image.

For example, when acquiring a facial image, in order to capture an image without shadow (i.e., shadow), it is necessary to continuously change the position of the patient so as to reach an unoccupied state. It takes a lot of time, and there is a problem that it causes inconvenience and trouble for the patient.

Also, in the past, when the illumination for scanning the face image acquisition or the illumination within the camera photographing space has to be made uniform, or the illuminance of a certain point within the space has to be adjusted to a desired illumination value, the illuminance is manually measured If it does not match, it is necessary to change the illumination position again and adjust it to the desired illuminance. Therefore, it takes a lot of time to adjust the illuminance and it takes a lot of time to acquire a face image to obtain .

First, according to the present invention, it is possible to easily control the scanning or photographing illumination suitable for acquiring a desired three-dimensional facial image in performing scanning of a three-dimensional facial image or camera photographing.

In other words, when the user wants to shoot in a shadowless state without shading (i.e., shadow), the user must change his / her position to be in an idle state, which causes a lot of time and inconvenience to the patient , Even if the illuminance in the scanning or camera shooting space is made uniform or the illuminance of a certain point in the space needs to be adjusted to a desired illuminance value, it is necessary to manually adjust the illuminance and manually adjust the illuminance, And there was a problem due to a lot of time.

However, according to the present invention, in performing scanning or camera photographing for three-dimensional facial image acquisition, even in the case of photographing in an unoccupied state, uniformity of illumination in a scanning or camera photographing space can be made uniform, When it is desired to adjust to a desired illumination value, the position of the first light source 203a and the second light source 203b is moved to a desired position along the Y-axis frame 10a and the X-axis frame 10b by the user's operation Therefore, the patient who needs the facial image acquisition does not move directly and can adjust the illuminance, so that it is not inconvenient.

In addition, according to the present invention, unlike the conventional method of manually adjusting the position of the illumination module and the height of the illumination lamp on the horizontal plane of the entire illumination module including the illumination lamp and the illumination lamp supporting part, Is easily controlled to move to a desired position along the Y-axis frame 10a and the X-axis frame 10b, the illumination adjustment operation using the illumination device is convenient and more accurate, and the time required for adjusting the illumination is significantly .

Particularly, the three-dimensional facial image acquisition system 1 of the present invention is characterized in that, in the height direction and the left-right direction of the lighting apparatus, the three- And the control unit 600 controls the vertical movement direction of the first light source 203a and / or the horizontal movement direction of the second light source 203b based on the difference in the values detected by the light intensity sensor And to control the driving motor by calculating the amount of lift of the first light source 203a and / or the amount of movement of the second light source 203b to the left and right.

First, when the illuminance value of the target point is input through the input unit 610, the X-axis frame 10b is displayed on the X- Axis frame 10a is measured and sent to the data storage unit 630. The control unit 600 controls the intensity of the illumination light input to the input unit 610 and the illumination intensity of the illuminance sensor 620, and compares the illuminance values of the target points sent to the data storage unit 630.

Accordingly, the illuminance value of the target point changes, and the illuminance sensor installed to detect the illuminance continuously measures the illuminance value of the target point and sends it to the controller 600 so that it can be compared with the illuminance value input as the target value, When the measured illuminance value of the target point corresponds to the input target value, the controller 600 stops driving the driving motor.

The X-axis frame 10b and the Y-axis frame 10a may be arranged so that the X-axis frame 10b and the Y- The illuminance sensors disposed at symmetric upper and lower positions symmetrically from the reference point and at left and right symmetrical positions from the reference point are controlled to operate, and when the illuminance values detected by the illuminance sensors The first light source 203a and the second light source 203b are controlled based on the difference between the first light source 203a and the second light source 203b.

That is, the control unit 600 controls the elevation direction of the first light source 203a and / or the elevation direction of the first light source 203a so that the illuminance difference within the space formed by the X-axis frame 10b and the Y- 203b, and controls the driving motor by calculating the lift amount of the first light source 203a and / or the left / right movement amount of the second light source 203b.

The plurality of illuminance sensors constituting the illuminance sensing unit 620 are continuously provided to the X-axis frame 10b until the illuminance difference inside the space formed by the X-axis frame 10b and the Y- And the Y-axis frame 10a are measured and sent to the controller 600 so that they can be compared with the input illuminance values.

After the illumination state inside the space defined by the desired X-axis frame 10b and the Y-axis frame 10a is controlled to the desired state, the scanner or the camera installed on the photographing device rail 30 is moved to the photographing device rail 30) to obtain a three-dimensional face image of a patient or the like to be imaged.

Therefore, according to the present invention, it is possible to acquire accurate three-dimensional face images faster and automatically, unlike the conventional method, and also it is possible to effectively reduce inconvenience not only for the operator but also for the patient through shortening the time for image acquisition.
