The ideal state of mental health is to maintain an intact personality, normal intelligence, correct cognition, appropriate emotions, reasonable will, positive attitude, appropriate behavior, and good adaptation. Psychological assessment can quickly and accurately display a person's mental state. Psychological assessment refers to the general term for conducting a comprehensive, systematic and in-depth analysis of the psychological phenomena of individuals or groups by using a combination of conversation, observation and testing methods under the joint guidance of biological, psychological, social and medical models.

Simultaneously, the light bar reflects light through the frosted reflector and softens the light on the face, facilitating that multiple cameras can fully and clearly capture the face under the reflection of the bright reflector. 2. The present invention can conceal the camera through the light shield and the one-way light-transmitting plate, thereby maintaining the hidden collection of portraits by the camera, reducing the lens effect when the user faces the camera directly, and achieving more accurate and natural facial changes during the psychological assessment of the user. The accuracy of the psychological assessment results is improved by identifying facial changes. When the adjustment knob is rotated, the transmission push bar drives the two movable connecting plates to swing relative to the sealing cover, and then the movable connecting plate drives the bright reflector to reflect light at different angles, thereby facilitating the reflection of portraits at different angles and positions.

8. The hidden facial data collection device based on psychological assessment according to claim 4, characterized in that: The rear end of the light shield (301) is fixedly connected to the sealing cover (302), the front end of the adjusting knob (303) passes through the middle of the sealing cover (302) and is connected to the middle of the transmission push bar (311) by a thread, the two ends of the transmission push bar (311) are slidingly connected to the sealing cover (302), the sealing cover (302) is rotatably connected to the rear ends of the two movable connecting plates (307), the front end of the transmission push bar (311) is in contact with the two movable connecting plates (307), and the two movable connecting plates (307), the bright reflector (308) and the second power socket (304) are all symmetrically installed relative to the transmission push bar (311).
9. The hidden facial data collection device based on psychological assessment according to claim 8, characterized in that: The light shield (301) and the two pressing plates (309) are connected via a first supporting spring (310), the pressing plate (309) is in contact with the front end of the movable connecting plate (307), the pressing plate (309) slides linearly back and forth along the axis of the first supporting spring (310), and the plurality of cameras (305) are linearly arranged along the side of the second power socket (304).
10. A hidden face acquisition method based on psychological assessment, characterized in that: The following steps are involved: S1: connecting the two display units (2) via the portrait concealment collection mechanism (3), and connecting one of the display units (2) to the upper end of the psychological assessment installation mechanism (1) via the support adjustment mechanism (4), turning on the power supply, and adjusting the angles of the two displays (201) when performing a psychological assessment on the user; S2: Specifically, the upper end of the positioning rod (406) is clamped and installed with the rotating seat (401) under the elastic support of the second support spring (407), and the positioning piece (408) is clamped and installed with the rotating seat (403) under the elastic support of the elastic rubber block (409). The display (201) swings relative to the support rod (402) through the two rotating seats (403). At the same time, the support rod (402) drives the rotating seat (401) to rotate inside the holding seat (404), thereby realizing arbitrary adjustment of the display angle of the display screen (202), meeting the requirements of maintaining facial acquisition and evaluation display when the user's face is in different positions; S3: The two fill-in lighting units (103) are symmetrically mounted relative to the mobile body (101), and a plurality of mounting angle plates (106) are linearly arranged along the side of the first power receiving base (105), and the angles between the plurality of frosted reflectors (107) and the mounting angle plates (106) increase from front to back, so that the light bar (108) can illuminate the inner side of the light shield (301) through the one-way light-transmitting plate (306), and at the same time, the light bar (108) performs frosted reflection through the frosted reflector (107) and softens the light to fill in the face, so that the plurality of cameras (305) can fully and clearly capture the face under the reflection of the bright reflector (308); S4: The camera (305) can be installed in a hidden manner by using the light shield (301) and the one-way light-transmitting plate (306), thereby maintaining the hidden collection of the human portrait by the camera (305), reducing the lens effect generated when the user directly faces the camera (305), achieving more accurate and natural facial changes during the psychological assessment of the user, and improving the accuracy of the psychological assessment results by recognizing facial changes; S5: A writing area is provided on the upper end surface of the movable support plate (102), and paper psychological assessment questions are placed and answered in the writing area. At the same time, the psychological assessment process and results of the user are conveniently displayed through two display screens (202). The adjustment knob (303) is rotated, and then the adjustment knob (303) drives the two movable connecting plates (307) to swing relative to the sealing cover (302) through the transmission push bar (311). Then, the movable connecting plates (307) drive the bright reflective plate (308) to reflect light at different angles, thereby facilitating the reflection of portraits at different angles and positions.
