Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of imaging recognition, and specifically refers to a dot matrix infrared light imaging recognition device. Background Art
[0002] Existing imaging technologies are mainly two-dimensional planes, and it is difficult to obtain the depth information of objects. The second is binocular imaging technology, but the resolution of objects obtained by binocular imaging technology is relatively low, and it is difficult to further perform precise defect detection on objects.
[0003] Dot matrix infrared light imaging technology uses pre-designed encoded dot matrix infrared light, and then projects the pattern onto the surface of a three-dimensional space object. Another camera is used to observe the distortion of the image formed on the three-dimensional physical surface. If the dot matrix infrared light pattern is projected onto a flat surface of the object, then the dot matrix infrared light pattern observed in the image is similar to the projected pattern, without distortion, except for a certain scale change according to the distance. However, if the object surface is not flat, then the observed dot matrix infrared light pattern will be distorted differently due to the different geometric shapes of the object surface, and it also varies according to the distance. Based on the known dot matrix infrared light pattern and the observed distortion, the three-dimensional shape and depth information of the object to be measured can be calculated according to the algorithm. Therefore, a new solution is proposed. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a dot matrix infrared light imaging recognition device.
[0005] To solve the above technical problem, the technical solution provided by the present invention is: a dot matrix infrared light imaging recognition device, which includes a support platform. On one side surface of the support platform, there is a second groove. On the upper surface inside the second groove, there is a main control board. At one side of the bottom surface of the second groove, there is a motor. Above the support platform and near one side of the motor, there is a panel. On the side surface of the panel away from the support platform, there is a first groove. On both side surfaces of the first groove and near the upper and lower ends, there are bearings. Inside the bearings, there is a threaded rod. The lower end of the threaded rod extending out of the bearing is fixedly connected to the output end of the motor. The outer side surface of the threaded rod is threadedly connected with a nut. On the side surface of the nut away from the support platform, there is a moving module housing. On the front surface of the moving module housing, from top to bottom, there are a first occlusion sensor, a first fill light, a first infrared lens, and a display. On the front surface of the moving module housing and near the first infrared lens, there is an infrared dot matrix projector. On the panel, there is a fixing plate. In the middle of the side surface of the fixing plate away from the support platform, there are two second fill lights. Between the second fill lights, there are a distance sensor, a second infrared lens, and a floodlight element in sequence. On both sides of the panel and at the positions of the moving module housing, a number of second occlusion sensors are evenly distributed. On one side surface of the second groove, there is a baffle hinged.
[0006] As an improvement, a coupling is provided at the lower end of the threaded rod extending out of the bearing, and the other end of the coupling is fixedly connected to the output end of the motor.
[0007] As an improvement, both the light blocking sensor 1 and the light blocking sensor 2 are set as light blocking interruption sensors with the model Risym33. The light blocking interruption sensor uses infrared light for detection, is not easily interfered by external stray light, adopts Schmitt trigger, has good waveform, stable signal, and signal output indication (when there is occlusion, the output is low level and the signal indicator light is on).
[0008] As an improvement, a vertical plate is fixedly connected between the sides of the panel away from the mobile module housing.
[0009] The main control board is set as a central processing controller with the model JY183, and the floodlight element is set as a low-power infrared dot matrix projector with the model CHQ02.
[0010] A dot matrix infrared light imaging recognition system, and the steps of the system are as follows:
[0011] Step a, when an object to be detected approaches the distance sensor, the distance sensor sends a signal to the main control board, and the main control board thus starts the floodlight element for recognition.
[0012] Step b, the floodlight element transmits the recognition result received in step a to the infrared lens 2 to identify whether it is the feature of the set recognition object. If it is recognized as the set recognition object, the main control board starts the fill light 2, the fill light 1, the light blocking sensor 2, and the light blocking sensor 1 for recognition.
[0013] Step c, the light blocking sensor 2 receives the recognition information in step b, judges the position of the area to be measured, and then sends a signal to the main control board. After receiving the signal, the main control board starts the motor to drive the mobile module housing to roughly move to the relevant height position through the threaded rod. The mobile module housing drives the light blocking sensor 1 to further measure the precise position of the mobile module housing, and starts the motor to accurately reach the measurement position through the threaded rod.
[0014] Step d, after step c, the main control board turns on the infrared dot matrix projector. The infrared lens 1 receives the recognition result of the infrared dot matrix projector and transmits the result to the main control board.
[0015] Step e, after step d, the main control board transmits the result to be displayed on the display.
[0016] The present invention has the following advantages: The three-dimensional information of the object space can be obtained according to the product device and system; the main control board obtains the phase difference according to the change of the received dot matrix infrared light pattern, and further converts it into depth information, and accurately calculates the appearance size of the object to be measured. Compared with other solutions, the dot matrix infrared light can obtain higher resolution, and thus obtain more detailed information on the three-dimensional size of the object space; the foreground and background can be distinguished, which is beneficial to the further analysis and recognition of the picture.
[0017] As an improvement, both the occlusion sensor 1 and the occlusion sensor 2 are set as optical occlusion interruption sensors. The optical occlusion interruption sensor uses infrared light detection, is not easily interfered by external stray light, adopts Schmitt trigger, has good waveform and stable signal output indication (when there is occlusion, the output is low level and the signal indicator light is on).
[0018] As an improvement, a vertical plate is fixedly connected between the sides of the panel away from the mobile module housing. BRIEF DESCRIPTION OF THE DRAWINGS

On one side of the support platform 201, there is a second groove 117. On the upper surface inside the second groove 117, there is a main control board 202. At one side of the bottom surface of the second groove 117, there is a motor 116. Above the support platform 201 and near one side of the motor 116, there is a panel 106. On the side of the panel 106 away from the support platform 201, there is a first groove 118. On both side surfaces of the first groove 118 and near the upper and lower ends, there are bearings 105. Inside the bearings 105, there is a threaded rod 114. The lower end of the threaded rod 114 extending out of the bearing 105 is fixedly connected to the output end of the motor 116. On the outer side surface of the threaded rod 114, there is a nut in threaded connection. On the side of the nut away from the support platform 201, there is a mobile module housing 113. On the front surface of the mobile module housing 113, from top to bottom, there are a first light shielding sensor 109, a first supplementary light 110, a first infrared lens 112, and a display 108 in sequence. Near the first infrared lens 112 on the front surface of the mobile module housing 113, there is an infrared dot matrix projector 111. On the upper surface of the panel 106, there is a fixing plate 119. In the middle of the side surface of the fixing plate 119 away from the support platform 201, there are two second supplementary lights 104. Between the second supplementary lights 104, there are a distance sensor 101, a second infrared lens 102, and a floodlight element 103 in sequence. On both sides of the panel 106 and located on both sides of the mobile module housing 113, there are a number of second light shielding sensors 107 evenly distributed. On one side surface of the second groove 117, there is a baffle 203 hinged.
[0025] The lower end of the threaded rod 114 extending out of the bearing 105 is provided with a coupling 115, and the other end of the coupling 115 is fixedly connected to the output end of the motor 116.
[0026] Both the first light shielding sensor 109 and the second light shielding sensors 107 are set as light shielding interruption sensors with the model Risym33.
[0027] Between the side surfaces of the panel 106 away from the mobile module housing 113, there is a vertical plate fixedly connected.
[0028] The main control board 202 is set as a central processing controller with the model JY183, and the floodlight element 103 is set as a low-power infrared dot matrix projector with the model CHQ02.
[0029] An infrared dot matrix light imaging recognition system, and the steps of the system are as follows:
[0030] Step a, when an object to be detected approaches the distance sensor 101, the distance sensor 101 sends a signal to the main control board 202, and the main control board 202 thereby starts the floodlight element 103, and the floodlight element 103 conducts recognition;
[0031] Step b: The floodlight element 103 transmits the result recognized in step a to the second infrared lens 102 to identify whether it is the feature of the set recognized object. If it is recognized as the set recognized object, the main control board 202 activates the second fill light 104, the first fill light 110, the second occlusion sensor 107, and the first occlusion sensor 109 for recognition;
[0032] Step c: The second occlusion sensor 107 receives the recognition information in step b, determines the position of the area to be measured, and then sends a signal to the main control board 202. After receiving the signal, the main control board 202 activates the motor 116 to drive the moving module housing 113 to roughly move to the relevant height position through the threaded rod 114. The moving module housing 113 drives the first occlusion sensor 109 to further measure the precise position of the moving module housing 113, and activates the motor 116 to precisely reach the measurement position through the threaded rod 114;
[0033] Step d: After step c, the main control board 202 turns on the infrared dot matrix projector 111. The first infrared lens 112 receives the recognition result of the infrared dot matrix projector 111 and transmits the result to the main control board 202;
[0034] Step e: After step d, the main control board 202 transmits the result to be displayed on the display 108.
[0035] In the specific implementation of the present invention, the screen of the product of the present invention faces the front and faces the object to be recognized; when the object to be detected approaches the distance sensor 101, the distance sensor 101 sends a signal to the main control board 202, and the main control board 202 receives the signal and thus activates the floodlight element 103. The floodlight element 103 recognizes the signal; the floodlight element 103 transmits the result of the received recognition to the second infrared lens 102 (model U229) to identify whether it is the feature of the set object to be recognized. If it is recognized as the set object to be recognized, the main control board 202 activates the fill light 104 and the first fill light 110 to perform light compensation on the object to be detected. The second occlusion sensor 107 and the first occlusion sensor 109 perform precise recognition and judge the position of the area to be detected, and then send the recognition and judgment information to the main control board 202. When the main control board 202 receives the information, it activates the motor 116. The motor 116 drives the nut to rotate, and the nut drives the moving module housing 113. The width of the panel of the moving module housing 113 is set to be greater than the width of the first groove, which limits the rotation of the nut. The threaded rod 114 rotates to drive the moving module housing 113 to move up and down, that is, to move roughly to the relevant height position. Then, the first occlusion sensor 109 on the outer side of the moving module housing 113 further measures the precise position of the moving module housing 113 and transmits it to the main control board 202. The main control board 202 activates the motor 116 to drive the moving module housing 113 to the precise position. Immediately afterwards, the main control board 202 turns on and recognizes the infrared dot matrix projector 111. The first infrared lens 112 (model U229) receives the recognition result of the infrared dot matrix projector 111 and transmits the result to the main control board 202 for classification, and then transmits the result to be displayed on the display 108; according to the product device and system of the present invention, detailed three-dimensional information of the object space can be obtained; compared with other imaging recognition technologies, the infrared dot matrix projector 111 can obtain a higher resolution, and thus obtain more detailed information on the three-dimensional size of the object space; the cooperation of the first occlusion sensor 109, the occlusion sensor 107 and the infrared dot matrix projector 111 can distinguish the foreground and background, which is beneficial to the further analysis and recognition of the picture.
[0036] The above describes the present invention and its implementation manners, and this description is not restrictive, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
