Technical Field
[0001] The utility model belongs to the technical field of image analysis equipment, and in particular relates to a human face fixing device used for a skin image analyzer. Background Art
[0002] With the continuous improvement of living standards, people's health and life concepts are constantly improving, and the state of facial skin has attracted much attention. People use some cosmetics on their faces to achieve the effects of skin care and beauty modification. However, the differences in skin quality and external environment among people lead to different effects of cosmetics, which requires further analysis and evaluation of facial skin conditions and effects. In the cosmetics industry, with the advancement of technology, the improvement of users' skin quality and the difference before and after makeup effects are tested and analyzed during product design, development and use, so as to position and design products according to different groups of people and recommend suitable products to different consumers. Therefore, the use of skin image analyzers for testing is becoming more and more common.
[0003] Skin image analyzers are used, on the one hand, to analyze competitive cosmetic products, and to find gaps in product efficacy and performance by testing skin parameters, which is beneficial to product development; on the other hand, they are used to analyze consumer skin conditions, test the skin improvements before and after the use of skin care products, and the makeup application and makeup lasting effects before and after the use of beauty products. The testing process requires photographing and analyzing the user's face before and after using skin care products. The existing face fixing device of the skin image analyzer is a fixed setting, and the shooting angle cannot be adjusted. There is often a deviation in the placement of the face when taking photos twice, resulting in the facial images taken twice before and after not completely overlapping, which in turn affects the accuracy of the analysis results.

DETAILED DESCRIPTION
[0015] The present invention is further described below in conjunction with the accompanying drawings in order to better understand the present technical solution.
[0016] like Figure 1-2 As shown, the utility model is a human face fixing device for skin image analyzer, which is mainly used to make the shooting angle of the same person in different time periods consistent when obtaining human face image information. The specific structure includes a face support 1, a left-right displacement mechanism 3 and a front-back displacement mechanism 2 arranged in sequence from top to bottom, and the face support 1 is composed of a face support bracket 101, a forehead top 102 installed at the upper end of the face support bracket 102, and a chin support 103 installed at the lower end of the face support bracket 101. The face support 1 is fixedly installed on the left-right displacement mechanism 3 to achieve the left-right displacement of the face support, and the left-right displacement mechanism 3 is installed on the front-back displacement mechanism 2 to drive the left-right displacement mechanism 3 and the face support 1 thereon to move forward and backward, so as to achieve the front-back and left-right adjustment of the face of the photographer.
[0017] Continue reading Figure 1-2 The left-right displacement mechanism 3 includes a slider 301, a left-right displacement support 302, two slider guide rails 303 and a left-right rotation rod 304. The chin support 103 is fixedly connected to the slider 301 by bolts. The left-right displacement support 302 has a U-shaped cross section. The two ends of the slider guide rail 303 are respectively fixedly connected to the inner side walls of the left-right displacement support 302. The slider 301 is correspondingly provided with a first through hole 305 for the slider guide rail 303 to pass through. One end of the left-right rotation rod 304 passes through a side wall of the left-right displacement support 302 and is fixedly connected to the slider 301. The part of the left-right rotation rod 304 extending into the left-right displacement support 302 is located between the two slider guide rails 303, and the left-right rotation rod 304 is provided with an external thread to cooperate with the internal thread on the left-right displacement support 302. The left-right rotation rod 304 can be installed on the left or right side of the left-right displacement support 302 as needed.
[0018] Continue reading Figure 1-2 The front-to-back displacement mechanism 2 includes a front-to-back displacement support 201, two front-to-back displacement guide rails 202 and a front-to-back rotating rod 203. The cross section of the front-to-back displacement support 201 is U-shaped. The two ends of the front-to-back displacement guide rails 202 are fixedly arranged on the inner wall of the front-to-back displacement support 201. The bottom side of the left and right displacement support 201 is provided with a second through hole 204 for the front-to-back displacement guide rails 202 to pass through. One end of the front-to-back rotating rod 203 passes through the side wall of the front-to-back displacement support 201 and is fixed to the bottom side of the left and right displacement support 302. Two groups of front-to-back displacement guide rails 202 and second through holes 204 are respectively provided. The part of the front-to-back rotating rod 203 extending into the interior of the front-to-back displacement support 201 is located between the two front-to-back displacement guide rails 202, and the front-to-back rotating rod 203 is provided with an external thread for use with the internal thread on the front-to-back displacement support 201. The front-to-back rotating rod 203 can be installed at the front end or the rear end of the front-to-back displacement support 201 as required.
[0019] When the utility model is used, the facial image of the subject before using the skin care product is first retrieved from the picture library. When taking the picture after using the skin care product, the subject puts the chin on the chin rest 103 so that the forehead is against the forehead top 102. The photographer starts to fine-tune the shooting angle according to the previous facial image. The shooting position can be adjusted left and right first or back and forth first. When adjusting the shooting angle left and right, the left and right rotating rods 304 are rotated. Under the action of the inner and outer threads, the left and right rotating rods 304 drive the slider 301 to move left and right along the slider guide rail 303, thereby driving the slider 301 to move left and right together. 01 The fixedly connected face support 1 is displaced left and right together. After being adjusted to a suitable angle, the front-to-back displacement mechanism 2 is adjusted. Specifically, the front-to-back rotation rod 203 is rotated. Under the action of the internal and external threads, the left-to-right displacement support 302 moves back and forth along the front-to-back displacement guide rail 202, thereby driving the left-to-right displacement mechanism 3 and the face support 1 set on the front-to-back displacement guide rail 202 to move back and forth together. The front-to-back displacement mechanism 2 and the left-to-right displacement mechanism 3 are adjusted in this way until the facial image of the person being photographed matches the existing facial image in the gallery, thereby ensuring the consistency of the image information taken before and after, and improving the accuracy of the skin parameter analysis and evaluation.
