Description

Technical Field

[0001] The present invention relates to the field of perception testing technology, and in particular to a perception testing device with precise sensing and monitoring effects. Background Art

[0002] Depth perception, also known as "stereoscopic perception" or "distance perception", refers to the three-dimensional perception of objects or the distance of different objects. The retina can only receive stimulation in two-dimensional space, and the reflection of three-dimensional space mainly depends on binocular vision. Depth perception is an essential instrument for psychology teaching experiments, and is also widely used in professional ability selection tests and training related to depth perception, such as drivers, gunners, athletes, etc. In addition, the famous visual cliff experiment shows that babies who have just learned to crawl already have quite good depth perception. Some children are born with defects in depth perception, and an important indicator is to check the ability of stereoscopic vision at different distances. There are nine modes for measuring and demonstrating depth perception: relative size of objects, occlusion, texture gradient, brightness and shadow, line perspective, aerial perspective, motion parallax, binocular convergence, and binocular parallax. At present, the equipment that can quantitatively measure errors is the depth perception tester, which is an instrument for studying the visual acuity in depth and testing the minimum threshold of visual error of binocular distance or depth.

[0003] A method, device, electronic device and medium for evaluating the comprehensive perception ability of crew members, with publication number CN118246788A, wherein the method comprises: constructing a test scene for testing the perception ability of crew members, obtaining a plurality of evaluation index data input by the test crew members based on the test scene, the perception ability comprises the ability to distinguish between sound and light signals, dynamic vision, dark vision, night vision, orientation perception, time perception, motion perception, depth perception and attention perception; based on the plurality of evaluation index data, determining the evaluation result of the comprehensive perception ability of the test crew members. The present invention constructs a multi-dimensional, comprehensive and objective evaluation system for the comprehensive perception ability of crew members by dividing the comprehensive perception ability into the ability to distinguish between sound and light signals, dynamic vision, dark vision and night vision, spatial perception, time perception, motion perception, depth perception and attention perception, so as to solve the problem that the evaluation content of the crew members' professional ability is not comprehensive enough in the prior art.

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Example 1

[0048] Reference Figure 1-Figure 9 , this embodiment relates to depth perception testing;

[0049] In the actual test process, the recording personnel first starts the equipment. After the test person enters the test room, he sits facing the observation window 3. The test person selects the depth perception module through the previous button, next button, return button and confirmation button on the wireless control component 4. At this time, the signal sent by the wireless control component 4 is received by the receiving control component 5. The receiving control component 5 can control the operation of the PLC playback control component 6 and the corresponding lighting components in the observation window 3 to achieve the optimal shadowless effect in the observation window 3; avoid giving the test person corresponding prompts due to the appearance of projection, which affects the quality of the final test.

[0050] In this embodiment, the ambient light control assembly 12 installed in the box 1 can be used to change the environmental conditions in the box 1, thereby better improving the test environment and better performing the depth perception test.

[0051] In this embodiment, the motion adjustment component 10, the observation window 3 and the PLC playback control component 6 are arranged horizontally in their length direction; at the same time, the three comparison rods 71 ​​can be observed through the observation window 3, and the belt motion component 75 in an observation comparison component 7 is automatically started, so that the component in the observation comparison component 7 becomes a reference component, so that the moving port 73 drives the comparison rod 71 to move. At this time, the first infrared emitting component 72 corresponds to one of the infrared sensing components 92, and the infrared information data can be received. The length direction of one of the infrared sensing components 92 is arranged perpendicular to the length direction of the PLC playback control component 6.

[0052] Among them, when the above-mentioned moving port 73 stops operating, the display broadcast component 2 will emit an indication sound to remind the subject to be ready, and after the countdown, the belt motion component 75 on the other two observation and comparison components 7 will be started, so that the belt motion component 75 drives the moving port 73, the first infrared emitting component 72 and the comparison rod 71 connected thereto to move, and the subject can control the position of the moving port 73 to stop through the depth and speed perception pause button on the wireless control component 4. At this time, the first infrared emitting component 72 on the moving port 73 will also correspond to the other two infrared sensing components 92 to realize data transmission. The distance difference between the three first infrared emitting components 72 can be quickly understood through the above data.

[0053] In this embodiment, when the reference observation and comparison component 7 stops operating, the subject can also be prompted to pay attention to observation. After that, the push-pull moving component 102 at the lower end of the observation and comparison component 7 is started to move the observation and comparison component 7 to the outside of the observation window 3 so that the subject cannot observe it. The display broadcast component 2 can remind the subject to start the test, so that the belt moving components 75 in the other two observation and comparison components 7 are operated to move the comparison rod 71 for depth testing. The distance difference between the three first infrared emitting components 72 can be understood through the cooperation of the infrared sensing component 92 and the first infrared emitting component 72.

[0054] Among them, the infrared data acquisition component 91 arranged at the lower end of the infrared sensing component 92 can receive the point where the infrared sensing component 92 receives the information of the first infrared emitting component 72, and can calculate the distance between the position and the infrared data acquisition component 91, so as to understand the depth perception ability of the subject through the deviation of the distance between the three first infrared emitting components 72 and the infrared data acquisition component 91. The above data can be quickly uploaded through the receiving control component 5, which is convenient for the staff to understand, and can also be effectively stored to form a depth perception test report of the subject.

[0055] Example 2

[0056] Reference Figure 1-Figure 9 , this embodiment relates to a speed perception test;

[0057] During the actual test, the motor assembly 103 is rotated to drive the mounting plate 101 to rotate, so that the longitudinal direction of the motion adjustment assembly 10 is perpendicular to the longitudinal direction of the PLC playback control assembly 6 and the observation window 3. At the same time, the comparison rod 71 is set outside the observation window 3. At the same time, the data that need to be recorded by the infrared sensing assembly 92, the infrared data acquisition assembly 91 and the first infrared emitting assembly 72 are: the operating speed of the belt motion assembly 75, the end points of the observation window 3 at both ends take the end points away from the side of the shielding member 84 as the starting point, the first infrared emitting assembly 72 starts recording when it passes, and stops recording when it passes another point of the observation window 3. At the same time, the distance between the first infrared emitting assembly 72 and the starting point is fully recorded. At the same time, the length of the observation window 3 is fixed data, and the distance of the shielding member 84 blocking the observation window 3 is also fixed data.

[0058] In this embodiment, the environment condition in the box 1 can be changed by the ambient light control component 12 installed in the box 1, so as to better increase the test environment condition and better perform the speed perception test.

[0059] In this embodiment, when conducting the test, the test subject can select the speed sensing module through the wireless control component 4. At this time, the PLC playback control component 6 in the box component 1 cooperates with the corresponding lighting component to make the box component 1 optimally achieve a shadowless environment; one of the belt motion components 75 is started to drive the comparison rod 71 to move to ensure a constant speed, which is the reference speed, until the comparison rod 71 moves out of the range of the observation window 3, and the infrared sensing component 92 arranged parallel to the long direction of the observation window 3 receives and records the signal of the comparison rod 71 in the above-mentioned first infrared emission component 72 to obtain the comparison data, and at the same time, the display broadcast component 2 starts the broadcast to prompt the test subject to prepare for the test. When prompting the test subject, the motor control component 88 operates to enable the lead screw telescopic component 87 to push the connecting plate 82 connected thereto to descend, so that the shielding component 84 can follow the connecting plate 82 to descend, and the observation window 3 can be blocked. In addition, the use of shading materials can avoid light leakage and projection.

[0060] In this embodiment, after the preparation work is completed, that is, after the distance between the second infrared emitting component 85 and the infrared sensing component 92 at its lower end reaches the set distance, the motor control component 88 can stop operating, and the display broadcast component 2 prompts the subject to prepare for the test and implements the countdown prompt. Another belt motion component 75 can drive another comparison rod 71 to perform a test at a speed different from the reference speed. In order to facilitate recording and testing, the test speed can be set as an integer multiple of the reference speed for subsequent comparison.

[0061] The subjects estimate the time required for the comparison rod 71 to move out of the observation window 3 by observing the moving speed of another comparison rod 71 in the observation window 3 that is not blocked by the blocking member 84, and temporarily pause the operation by pressing the depth and speed perception pause button.

[0062] Among them, when the other comparison rod 71 starts to start, the infrared sensing component 92 arranged parallel to the long direction of the observation window 3 receives and records the signal of the first infrared emitting component 72; when the depth and speed perception pause button is pressed, the infrared sensing component 92 will also record the position of the other first infrared emitting component 72, and obtain the distance between the other first infrared emitting component 72 and the observation window 3 and the moving time of the other first infrared emitting component 72 through the advance data, so as to compare with the comparison data and determine the subject's perception of speed.

[0063] Then the third comparison rod 71 is controlled to operate for comparison.

[0064] In this embodiment, the other two first infrared emitting components 72 can be moved at different speeds, and the speed perception of the test subject can be measured by recording data.

[0065] Example 3

[0066] Reference Figure 1-Figure 9 ,This embodiment relates to a time perception test;

[0067] In this embodiment, the subject selects to perform a time perception test through the button on the wireless control component 4, and selects to perform a primary perception test or a perception training test, and the motion adjustment component 10 and the observation comparison component 7 are arranged to cooperate so that the comparison rod 71 is completely different from that observed through the observation window 3, and the shielding component 84 is reset to fully expose the observation window 3, and the primary perception test or the perception training test is started, and the display broadcast component 2 broadcasts to remind the subject to prepare for the test, and the test is performed after the countdown is completed.

[0068] Among them, two groups of comparison films are set in the primary perception module, and the rhythm classification of the two groups of films is the same, that is, two films with slow rhythm are used as one group; two films with steady rhythm are used as one; two films with fast rhythm are used as one group.

[0069] When the subjects are tested, the video group is played from slow to fast. For example, in the first test, the PLC playback control component 6 plays a video with a slow rhythm for a certain period of time and then stops, and then switches to another video with a slow rhythm and plays it again. After the subjects determine that the playing time of the two videos is the same, they press the time perception pause button on the wireless control component 4 to stop playing, and the PLC playback control component 6 records the playing time of the two videos.

[0070] Then, we conducted comparative tests on steady-paced films and fast-paced films, and recorded the test data to understand the test subjects' time perception ability.

[0071] In this embodiment, a perception training module is also provided, in which the two groups of videos used for comparison have different rhythms. The video played first may be a video with a steady rhythm. After setting the playback time, the comparison video may be a video with a slow rhythm or a fast rhythm, so as to facilitate the subjects to exercise their time perception.

[0072] In actual tests, the corresponding data are measured and recorded through the infrared data acquisition component 91, the infrared sensing component 92, the first infrared emitting component 72, the belt motion component 75, the second infrared emitting component 85, the PLC playback control component 6 and the receiving control component 5, and the corresponding computer components can also be connected to quickly input the collected data to form corresponding tables or perform comparative calculations.

[0073] In this embodiment, the receiving control component 5 is connected to the wireless control component 4, can sense the button pressing on the wireless control component 4, can control the automated components in the observation and comparison component 7 and the motion adjustment component 10 through the receiving control component 5, and can also be connected to the display and broadcast component 2, play the selection of the wireless control component 4 through the display and broadcast component 2, and after confirmation, broadcast according to the process data, which is convenient for the subjects to measure, and the display and broadcast component 2 is connected to the receiving control component 5. After the broadcast, the receiving control component 5 can control the PLC playback control component 6, the observation and comparison component 7, the shielding component 8 and the motion adjustment component 10 to perform corresponding operations, and the receiving control component 5 can be connected to the infrared detection component 9 for data collection.

[0074] In this embodiment, the data collected by the infrared data acquisition component 91, the infrared sensing component 92, the first infrared emission component 72, the belt motion component 75, the second infrared emission component 85 and the PLC playback control component 6 include:

[0075] The distance between the corresponding points of the infrared data acquisition component 91 and the first infrared emitting component 72 and the infrared sensing component 92 at the lower end of the infrared data acquisition component 91; the distance between the corresponding points of the infrared data acquisition component 91 and the first infrared emitting component 72 and the two ends of the observation window 3 in the long direction, and the distance between the second infrared emitting component 85 and the infrared sensing component 92; the length of the film played by the PLC playback control component 6; the rotation speed of the belt motion component 75; through the measurement of the above data, the test situation can be perceived in terms of time, depth and speed; and when the data is recorded, the data can be quickly collected through the receiving control component 5, and the data can be transmitted to the computer device connected to the receiving control component 5, and a corresponding database is set in the computer device to facilitate classified storage and rapid calculation according to the corresponding formula, and the formula can adopt the existing perception test formula.

[0076] For example, taking the measurement of time perception as an example, the absolute error (AE), relative error (Ratio) and coefficient of variation (CV) indicators; among them, AE = (copy time - standard time) / standard time, the larger the AE, the smaller the individual time.

[0077] The lower the accuracy of the copy: Ratio = copy time / standard time. A score greater than 1 indicates that the individual overestimates (overestimates) the standard time; CV = standard deviation / mean copy time, which reflects the consistency of judging the target time interval.

[0078] In the present invention, the subject can wear the head detection component 11 on the head, and can insist on detecting the electroencephalogram during the test, so as to understand the location of the active area of ​​the brain when the subject is undergoing different tests. The monitoring principles of the monitoring scheme are all existing technologies and do not need to be specifically explained. At the same time, the detected data can be uploaded, which is convenient for technical personnel in the field to link with electroencephalogram science.

[0079] In the present invention, corresponding components are set in the display and broadcast component 2, and corresponding PLC control components are set, and corresponding programs are pre-set to divide it into three modules, corresponding to depth, speed and time perception tests respectively. After the test subject selects the corresponding test, he can enter the corresponding module, and after the signal receiving module receives the corresponding information, it can control the voice broadcast module and the voice receiving module to operate, so as to effectively perform corresponding prompts. For example, when performing depth perception, the prompt is first performed:

[0080] In the first step, the display broadcast component 2 sends out: whether to conduct a depth perception test, please answer: yes or no; so as to perceive the voice of the test person to proceed to the next step (sound perception and corresponding procedures through perception are existing technologies and no further explanation is required);

[0081] If the perception answer is yes, then the second step is performed, and the display broadcast component 2 emits: after a "beep" sound, a depth perception test is performed, first, the first comparison rod 71 moves and stops moving after a "beep" sound;

[0082] When the first comparison rod 71 stops moving, the third step is performed and the display and announcement component 2 sends: please press the "confirm" key to control the second comparison rod 71 to move; and press the "depth and speed perception pause" key to stop the operation;

[0083] After pressing the "Depth, Speed ​​Perception Pause" button, the display and announcement component 2 prompts to operate the third comparison rod 71, and after pressing the "Depth, Speed ​​Perception Pause" button again, the display and announcement component 2 announces that the first set of perception tests is completed and the test results are being entered; and prompts to conduct a second test. Each test can be set to multiple sets of tests as needed to improve the test effect.

[0084] In actual operation, corresponding settings can be made according to needs. The setting principles and corresponding operating components are all existing in the art and do not need to be specifically explained.

[0085] The speed and time can also be set with corresponding sound prompts as needed, so as to provide operating guidance for the subjects.

[0086] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
