Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of head and face measurement, in particular to a three-camera multi-spectral facial skin quantitative analyzer. BACKGROUND

[0002] Placing a person's head and face in a shooting device can automatically shoot images of different angles, different spectra and different time points. Compared with cameras and mobile phones, such devices can provide reliable and stable light source control, head and face position control, shoot higher quality photos, provide multi-aspect image data collection, and further perform more professional index analysis. Head and face measurement has developed for many years. Different images are shot by using different spectra (UVA, parallel polarized light, cross polarized light, Wood's light, ultraviolet light, blue light, etc.) to analyze surface features and structural features, and provide quantitative measurement and evaluation functions such as pre-treatment severity evaluation and post-treatment efficacy evaluation for beauty care, medical plastic surgery.

[0003] However, since a face is a three-dimensional target and a camera shoots a two-dimensional image, it is impossible to completely present facial features from one side. According to the actual use of skin fields such as laser beauty, it is generally necessary to shoot photos of three directions of the front, left side and right side. The current collection device solution is that the face does not move and the device rotates to shoot the front, left side and right side of the face from different angles, such as the VISIA device of the United States, or the face rotates and the device does not move, such as the AISIA Q1 brand of the European brand and the Mescure Medical brand. In this way, once the facial image is collected, it needs to be rotated and placed in three positions for shooting, which causes long business time. At the same time, since the size of the head and face of a person is different, different groups of people need to focus the camera in advance when using, which also causes the problem of insufficient use convenience. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a three-camera multi-spectral facial skin quantitative analyzer, which solves the problem that the existing facial collection device needs to be rotated and placed in three positions for shooting once the facial image is collected, which causes long business time.

[0026] The photoelectric assembly 2 comprises a mounting shell 201, the bottom of the mounting shell 201 is fixedly connected to the top of the long connecting rod 3, respectively, the middle part of the mounting shell 201 is fixedly connected with a camera 202 on the side facing the sleeve 18.

[0027] In this embodiment, since the head size of each detected person is different, the imaging focus of each camera 202 cannot be guaranteed to fall perfectly on the face of the detected person. In order to achieve rapid focusing, the distance between each camera 202 and the detected person can be adjusted to achieve rapid focusing, improve work efficiency, and adapt to the use of different groups of people.

[0028] The inside of the outer cylinder 15 is slidingly connected with a lifting block 10, the bottom of each lifting guide rod 11 penetrates the top of the outer cylinder 15 and is fixedly connected to the top of both sides of the lifting block 10, respectively, the center of the inner wall of the top end of the outer cylinder 15 is rotatably connected with a screw rod 14, the outside of the screw rod 14 is threadedly connected to the middle part of the lifting block 10, the bottom end of the screw rod 14 is fixedly connected to the driving end of a motor 13, and the outside of the motor 13 is fixedly connected to the inside of the lower part of the outer cylinder 15.

Further, since the camera 202 also realizes up and down movement, in order to ensure that the focus falls on the face of the detected person without running up and down, the head of the detected person can also realize synchronous up and down movement with the camera 202 through the driving of the lifting guide rod 11, realizing perfect imaging.

[0032] Further, the edge of the mounting shell 201 is fixedly connected with a plurality of illuminating lamps 203 on the side facing the sleeve 18.

The light sources of each group of illuminating lamps 203 include but are not limited to LED light, parallel polarized light, cross polarized light, Wood's light, ultraviolet light, near infrared, blue light and different light spectra, so as to meet the illumination of different light spectra collected by different cameras 202. By adjusting the spectral imaging power and direction, good imaging effect is realized at three different angles under different spectra, meeting the needs of medical analysis.

[0033] Further, the upper side of the sleeve 18 is provided with a head supporting pad 12. The bottom of the head supporting pad 12 is fixedly connected to the top of the two lifting guide rods 11. The head supporting pad 12 is used to fix the head of the detected person.

[0034] The top of the sleeve 18 is fixedly connected with a shielding cover 1. The inside of the shielding cover 1 is coated with a reflective material. The reflection is used to improve the illumination brightness and realize the non-dead-angle illumination.
