Description

Technical Field

[0001] The invention relates to the technical field of psychology classroom equipment, in particular to a psychology classroom micro-expression recording device. Background Art

[0002] In psychology classes or psychological counseling, most counselors will use micro-expressions to judge the consultant's mood or psychology. Facial expressions are an important feature of people's expression of feelings or emotions. The analysis of facial expressions can effectively obtain people's emotional information; the collection of expressions has become an important part of expression recognition and output. The effective collection of expressions is the basis of emotion recognition, and only then can we effectively conduct psychological classroom teaching according to the changes in the consultant's expressions.

[0003] Based on the above, the inventors have found that the existing micro-expression recording device for psychology classes has the following main deficiencies. For example, most existing psychology classes use hanging monitors to record the micro-expressions of the consultant. The consultant's head turning action will make the face turn away from the monitor, and the consultant's facial expression cannot be monitored in real time, which makes it easy to miss the consultant's key expressions. Therefore, a recording device that can capture micro-expressions is needed. Summary of the invention

[0023] The recording device 23 includes a sliding structure 231, a support frame 232, a pulley 233, a servo motor 234, a transmission belt 235, and a recording structure 236. The sliding structure 231 is slidably matched with the end face of the slide rail 22. The support frame 232 is fixedly connected to the bottom of the sliding structure 231. There are two pulleys 233, and the pulleys 233 are respectively arranged on the end faces of both sides of the support frame 232. The servo motor 234 is installed on the inner end face of the support frame 232. The transmission belt 235 connects the sliding structure 231 with the end face of the servo motor 234. The recording structure 236 is fixedly installed on the bottom end face of the support frame 232. The pulley 233 is movably matched with the top of the two balance card plates 24, which is conducive to the overall movement of the recording device 23 to clearly record the facial micro-expressions of the consultant.

[0024] The sliding structure 231 includes a sliding guide wheel a1, a support frame a2, and a belt loop a3. The two sides of the sliding guide wheel a1 are engaged with the support frame a2. The support frame a2 is fixedly connected to the top end surface of the support frame 232. The belt loop a3 is located at the side end of the sliding guide wheel a1, and the belt loop a3 is movably cooperated with the transmission belt 235. The end surface of the sliding guide wheel a1 is in an arc shape, which is conducive to the sliding guide wheel a1 to drive the recording device 23 to move and record the consultant's facial micro-expressions.

[0025] Based on the above embodiment, the specific working principle is as follows: two recording devices 23 are used to slide on the end surface of the slide rail 22 to record the micro-expressions on the consultant's face, and then two balancing card plates 24 are used to support the left and right sides of the recording device 23, so that the recording device 23 can slide smoothly to avoid jitter in the recorded image, and the recording device 23 can shoot the consultant's face through the one-way perspective glass plate 25, while the consultant cannot see the recording device 23, so the consultant's face can be better recorded to prevent the consultant from feeling uncomfortable, and the consultant can also be monitored through the network. Module 3 transmits and records the recorded impact, and then uses the servo motor 234 to cooperate with the transmission belt 235 through the wheel, so that the transmission belt 235 can drive the sliding structure 231 to slide, so that the recording device 23 can be moved as a whole, so that the recording structure 236 can clearly record the consultant's facial micro-expressions, and then use the support frame a2 to support the sliding guide wheel a1 to be stuck on the end face of the slide rail 22, and then the transmission belt 235 and the belt ring a3 are used to cooperate to drive the sliding guide wheel a1 to rotate, so that the sliding guide wheel a1 can drive the recording device 23 to move and record the consultant's facial micro-expressions.

[0026] Example 2: Please refer to Figure 6-Figure 8 , the specific embodiments of the present invention are as follows: The recording structure 236 includes a frame s1, a driving device s2, a rotating shaft s3, a round tooth disk s4, and a camera s5. The frame s1 is fixedly installed on the bottom end face of the support frame 232, the driving device s2 is fixedly installed on the inner left end face of the frame s1, the rotating shaft s3 is fixedly installed in the middle position of the rear side of the frame s1, the round tooth disk s4 is snap-fitted on the end face of the rotating shaft s3, and the camera s5 is fixedly connected to the bottom end face of the round tooth disk s4. The round tooth disk s4 is meshed with the end face of the driving device s2, which is conducive to pointing the camera s5 toward the consultant's face to record the consultant's facial micro-expressions.

[0027] The driving device s2 includes a locking tube s21, a sliding block s22, a transmission rack s23, a transmission gear s24, and a driving motor s25. The locking tube s21 is fixedly installed on the inner left side of the frame s1.
