Contactless elevator control system

Abstract

A contactless elevator control system includes a control panel with multiple buttons, an image processor, a first lens module, and a second lens module. The first lens module and the second lens module are arranged at two adjacent corners of the control panel. When an object falls into a detection range, the image processor obtains a first imaging position of the object from a first image captured by the first lens module, and obtains a second imaging position of the object from a second image captured by the second lens module. Based on the relative position information of the first imaging position, the second imaging position, and the first imaging position and the second imaging position relative to the first lens module and the second lens module, the image processor determines the corresponding position of the object on the control panel, and triggers the corresponding button on the control panel based on the position.

[0002] With the prevalence of infectious diseases such as COVID-19, efforts are underway to minimize direct and indirect interpersonal contact to reduce the risk of contracting viruses and bacteria. Elevator control panels, particularly the buttons on them, pose a high-risk source of disease transmission due to their high level of contact. Therefore, a reliable and robust contactless elevator control system is urgently needed, allowing users to effectively control elevator operations without touching the control panel or buttons.

[0016] The present disclosure is susceptible to numerous modifications and alternative forms. Some representative embodiments are illustrated in the accompanying drawings and are described in detail herein. However, it should be noted that the present disclosure is not intended to be limited to the particular forms disclosed herein. On the contrary, the present disclosure encompasses all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure, as defined by the appended claims. DETAILED DESCRIPTION

[0017] The present disclosure provides a variety of different embodiments or examples for implementing different features of the subject matter described herein. The specific examples of components and configurations described below are presented to simplify the present disclosure. Of course, they are merely examples and are not intended to be limiting. For example, a configuration in which a "first feature is located above a second feature" may include an embodiment in which the first feature and the second feature are in direct contact, and may also include an embodiment in which an additional feature is located between the first feature and the second feature, preventing the first feature and the second feature from being in direct contact.

[0018] Additionally, spatially relative terms such as "above," "below," "in front of," and "behind" may be used throughout this disclosure for simplicity to describe an element or feature in its relationship to another element or feature as depicted in the figures. These spatially relative terms are intended to encompass the orientation depicted in the figures as well as different orientations of the device in use or operation. The device may be oriented in other orientations (rotated 90 degrees or at other orientations), in which case the spatially relative terms used throughout this disclosure should be interpreted accordingly.

[0019] Figure 1A 、 Figure 1B and Figure 1C FIG is a schematic diagram showing an exemplary embodiment of an elevator operating system 100 according to the present disclosure. Figure 1A Elevator control system 100 includes a control panel 102, an image processor (not shown), and two lens modules 104 and 106. Lens modules 104 and 106 are respectively located at two adjacent corners of the control panel. The field of view (FOV) of both lens modules 104 and 106 covers the entire control panel 102. Typically, control panel 102 is mounted on the elevator wall, perpendicular to the ground; however, the present disclosure is not limited thereto.

[0020] See also Figure 1B The control panel 102 includes buttons 108a, 108b, ..., 108n for controlling the operation of the elevator.

[0021] As mentioned above, the fields of view of both the lens modules 104 and 106 cover the entire control panel 102. To achieve this, the lens modules 104 and 106 must be positioned slightly (e.g., 5 cm) higher than the control panel 102 in the z-direction (the direction perpendicular to the xy plane of the control panel 102) to prevent the fields of view of the lens modules 104 and 106 from being blocked. Figure 1C shown.

[0022] Figure 2 FIG. 1 is a schematic diagram showing an exemplary non-contact detection mechanism of an elevator control system 100 according to the present disclosure. Figure 2As shown, the field of view of the lens module 104 (or 106) in the yz plane is divided by rays 201a and 201b into a detection zone 202 and a non-detection zone 204. The area between rays 201a and 201b is the detection zone 202, while the area outside the detection zone 202 is the non-detection zone 204. The angle α between rays 201a and 201b is less than the angle of view of the lens module 104 (or 106) in the yz plane. In front of the control panel 102, there is a virtual plane 208, parallel to the control panel 102 and separated from the control panel 102 by a distance (e.g., 5 cm) in the z direction. Virtual plane 208 is located within the detection zone 202. When an object 206 (e.g., a user's finger) approaches (but does not need to touch) a button 108m on the control panel 102, the button 108m is triggered, as described below.

[0023] Figure 3 FIG is a schematic diagram showing an example of a virtual plane 208 according to the present disclosure. Figure 3 In the xy plane, the field of view of the lens module 104 (or 106) covers the control panel 102 (not shown in FIG. Figure 3 The image in the field of view corresponds to a plurality of pixels (pixels, in Figure 3 However, in the field of view, only the buttons 108a to 108n on the control panel 102 (not shown) Figure 3 Therefore, in order to eliminate unnecessary computation caused by objects that are not located in the ROI, we define the subset of pixels as a virtual plane 208 (in Figure 3 ), where the virtual plane 208 covers the area formed by the buttons 108 a - 108 n on the control panel 102 .

[0024] In the following example, object 206 is (but is not limited to) a user's finger. When object 206 enters detection zone 202 and is located within virtual plane 208, lens module 104 (or 106) captures an image of object 206. In other words, the detection range of elevator control system 100 is the intersection of detection zone 202 and virtual plane 208. If the time that object 206 remains within virtual plane 208 reaches a predetermined threshold (e.g., but not limited to, 0.5 to 1 second), lens module 104 (or 106) transmits the image of object 206 to an image processor, which calculates the image position of object 206 in the image. The residence time of the object 206 within the virtual plane 208 can be measured using conventional techniques, such as, but not limited to, dividing a threshold time by the frames per second (FPS) of the lens module 104 (or 106) to obtain a target number of image frames. When the number of image frames containing the object 206 reaches the target number of image frames, it can be determined that the residence time of the object 206 within the virtual plane 208 has reached the threshold time.

[0025] Figure 4 FIG2 is a schematic diagram showing an exemplary position calculation mechanism of an elevator control system 100 according to the present disclosure. On the xy plane, the coordinates of the lens module 104 are known (X1, Y1), the coordinates of the lens module 106 are known (X2, Y2), and the coordinates of the object 206 are to be determined (X, Y). When the object 206 enters the detection range and stays for a period of time, the lens modules 104 and 106 respectively capture the first image and the second image of the object 206, and transmit the first image and the second image to the image processor; then, the image processor calculates the position of the object 206 in the first image. Figure 4 The angle θ1 in the image is calculated by the imaging position of the object 206 on the second image. Figure 4 The angle θ2 is obtained by triangulation. The coordinates (X, Y) of object 206 can be obtained from (X1, Y1), (X2, Y2), θ1, and θ2 using conventional triangulation methods. After obtaining the coordinates (X, Y) of object 206, the image processor maps (X, Y) to button 108m on control panel 102 and transmits a command signal representing button 108m to control panel 102. Control panel 102 responds to the command signal and triggers button 108m.

[0026] Figure 5 FIG. 1 is a schematic diagram showing another exemplary embodiment of an elevator control system 100 according to the present disclosure. Figure 5As shown, lens modules 104 and 106 include light-emitting diodes (LEDs) 502 and 504, respectively, which emit, for example, infrared light, serving as the light source for lens modules 104 and 106. When lens module 104 (or 106) captures an image of object 206, object 206 is illuminated by the light emitted by LED 502 (or 504), which reflects the light to the image sensor of lens module 104 (or 106), causing the image of object 206 to appear on the image sensor. However, when object 206 approaches lens module 104 (or 106), the brightness of object 206 increases, potentially causing the image on the image sensor of lens module 104 (or 106) to be overexposed. This results in an unclear image position of object 206, making it impossible to determine the coordinates of object 206 using triangulation methods. To address this issue, the lighting pattern of LEDs 502 and 504 must be adjusted, as detailed below.

[0027] Figures 6A to 6D show Figure 5 An example image capture mechanism of the example elevator control system 100 is shown in FIG. When the lens module 104 (or 106) captures an image of the object 206, the LEDs 502 and 504 illuminate at a first brightness and a second brightness, respectively. The first brightness is high brightness (e.g., 100% brightness of the LEDs 502 and 504), and the second brightness is low brightness (e.g., 20% brightness of the LEDs 502 and 504). This allows the lens modules 104 and 106 to capture a high-brightness image and a low-brightness image of the object 206 at the first brightness and the second brightness, respectively. The image processor then selects a clear image of the object 206 from the high-brightness image and the low-brightness image for subsequent triangulation calculations.

[0028] Figure 6A and Figure 6B The lens module 104 is shown in two ways of photographing the object 206. Figure 6A In the embodiment, the LED 502 emits light at a first brightness (high brightness), so that the lens module 104 captures a high-brightness image of the object 206 and transmits the high-brightness image to the image processor; and Figure 6B In the embodiment of the present invention, LED 502 emits light at a second brightness (low brightness), causing lens module 104 to capture a low-brightness image of object 206 and transmit the low-brightness image to the image processor. The image processor then selects one of the high-brightness image and the low-brightness image, which shows a clear image of object 206, as the first image for subsequent triangulation calculations.

[0029] Similarly, Figure 6C and Figure 6D The lens module 106 is shown in two ways of photographing the object 206. Figure 6CIn the embodiment, LED 504 emits light at a first brightness (high brightness), so that the lens module 106 captures a high-brightness image of the object 206 and transmits the high-brightness image to the image processor; and in the embodiment, LED 504 emits light at a first brightness (high brightness), so that the lens module 106 captures a high-brightness image of the object 206 and transmits the high-brightness image to the image processor; Figure 6D In the embodiment of the present invention, LED 504 emits light at a second brightness (low brightness), causing lens module 106 to capture a low-brightness image of object 206 and transmit the low-brightness image to the image processor. The image processor then selects one of the high-brightness image and the low-brightness image, which shows a clear image of object 206, as the second image for subsequent triangulation calculations.

[0030] Figures 7A to 7E show various possible imaging states of the lens modules 104 and 106 when the object 206 is located at different positions on the control panel 102. Figure 7A In the example, object 206 is at a moderate distance from lens modules 104 and 106. The image captured by lens module 104 includes a high-brightness image 711 and a low-brightness image 712, while the image captured by lens module 106 includes a high-brightness image 713 and a low-brightness image 714. High-brightness images 711 and 713 are clear, while low-brightness images 712 and 714 are darker. Therefore, high-brightness image 711 of lens module 104 is selected as the first image, and high-brightness image 713 of lens module 106 is selected as the second image.

[0031] exist Figure 7B In FIG. 1 , the object 206 is closer to the lens module 104 and farther away from the lens module 106. The image captured by the lens module 104 includes a high-brightness image 721 and a low-brightness image 722, while the image captured by the lens module 106 includes a high-brightness image 723 and a low-brightness image 724. Figure 7B As shown, because object 206 is close to lens module 104, the image brightness of object 206 on lens module 104 is higher, resulting in overexposure of high-brightness image 721 and an unclear image of object 206. In contrast, low-brightness image 722 is a clearer image. Furthermore, because object 206 is far from lens module 106, the image brightness of object 206 on lens module 106 is lower. At this time, high-brightness image 723 is still clearly imaged, while low-brightness image 724 is insufficiently bright and an unclear image of object 206. Therefore, low-brightness image 722 of lens module 104 is selected as the first image, and high-brightness image 723 of lens module 106 is selected as the second image.

[0032] Similarly, in Figure 7C In FIG. 1 , the object 206 is farther from the lens module 104 and closer to the lens module 106. The image captured by the lens module 104 includes a high-brightness image 731 and a low-brightness image 732, while the image captured by the lens module 106 includes a high-brightness image 733 and a low-brightness image 734. Figure 7C As shown, because object 206 is far from lens module 104, the image brightness of object 206 on lens module 104 is low. At this time, high-brightness image 731 can still be clearly imaged, while low-brightness image 732 is insufficiently bright, and the image of object 206 is unclear. Furthermore, because object 206 is close to lens module 106, the image brightness of object 206 on lens module 106 is high, causing high-brightness image 733 to be overexposed, and the image of object 206 is unclear. In comparison, low-brightness image 734 is a clearer image. Therefore, high-brightness image 731 of lens module 104 is selected as the first image, and low-brightness image 734 of lens module 106 is selected as the second image.

[0033] exist Figure 7D In the example, object 206 is at a moderate distance from lens module 104, but relatively far from lens module 106. The image captured by lens module 104 includes high-brightness image 741 and low-brightness image 742, while the image captured by lens module 106 includes high-brightness image 743 and low-brightness image 744. At this point, high-brightness images 741 and 743 are reasonably clear, while low-brightness images 742 and 744 are insufficiently bright, resulting in an unclear image of object 206. Therefore, high-brightness image 741 of lens module 104 is selected as the first image, while high-brightness image 743 of lens module 106 is selected as the second image.

[0034] Similarly, in Figure 7E In the example, object 206 is relatively far from lens module 104, but at a moderate distance from lens module 106. The image captured by lens module 104 includes high-brightness image 751 and low-brightness image 752, while the image captured by lens module 106 includes high-brightness image 753 and low-brightness image 754. At this point, high-brightness images 751 and 753 are reasonably clear, while low-brightness images 752 and 754 are insufficiently bright, resulting in an unclear image of object 206. Therefore, high-brightness image 751 of lens module 104 is selected as the first image, while high-brightness image 753 of lens module 106 is selected as the second image.

[0035] Figure 8 Another example elevator control system 800 is shown. The elevator control system 800 has three or more lens modules (four lens modules are used as an example below, but are not limited thereto). Compared with the elevator control system 100 described above, it can have higher reliability and environmental tolerance. Figure 8In the embodiment, lens modules 804, 806, 808, and 810 are respectively disposed at the four corners of the control panel 802, wherein lens module 804 is adjacent to lens modules 806 and 810, lens module 806 is adjacent to lens modules 804 and 808, lens module 808 is adjacent to lens modules 806 and 810, and lens module 810 is adjacent to lens modules 804 and 808. The structure and operation of lens modules 804, 806, 808, and 810 are similar to those of lens modules 104 or 106 described above, and thus will not be described in detail.

[0036] One advantage of setting up three or more lens modules is that we can calculate a set of possible positions from every two adjacent lens modules, and then take the intersection solution of these possible positions to filter out possible erroneous solutions caused by external interference (such as reflective objects), and / or when one of the lens modules is damaged, there are still two or more lens modules that can perform correct calculations. Figure 8 Taking the four lens modules 804, 806, 808, and 810 in the figure as an example, a set of possible positions is calculated from every two adjacent lens modules, then there will be four sets of possible positions (calculated by lens modules 804 and 806, 806 and 808, 808 and 810, and 810 and 804 respectively). Then, the intersection of these four sets of possible positions is taken to obtain the position of the object.

[0037] Figure 9 An example of the above calculation process is shown. On the xy plane, the coordinates of the lens module 804 are known (X1, Y1), the coordinates of the lens module 806 are known (X2, Y2), and the coordinates of the object 902 (such as the user's finger) are to be determined (X, Y). When the object 902 enters the detection range and stays for a period of time, the lens modules 804 and 806 respectively capture the first image and the second image of the object 902, and transmit the first image and the second image to the image processor; then, the image processor calculates the position of the object 902 in the first image. Figure 9 The angle θ1 in the image is calculated based on the imaging position of the object 902 on the second image. Figure 9The angle θ2 in the image is obtained; according to the conventional triangulation method, the coordinates of the first position of the object 902 can be obtained from (X1, Y1), (X2, Y2), θ1 and θ2. Subsequently, the lens modules 806 and 808, the lens modules 808 and 810, and the lens modules 810 and 804 each perform the above-mentioned shooting procedure once, and the image processor respectively obtains the coordinates of the second, third and fourth positions of the object 902. If the coordinates of at least one of the first, second, third and fourth positions are not unique due to external interference or damage to the lens module, the image processor uses the intersection of the coordinates of the first, second, third and fourth positions as the position of the object 902, and maps the position of the object 902 to the button on the control panel 802. Subsequently, the image processor transmits a command signal representing the button to the control panel 802, so that the control panel 802 responds to the command signal and triggers the button.

[0038] When at least one of the coordinates of the first, second, third, and fourth positions is not unique, the image processor uses the intersection of the first, second, third, and fourth positions as the coordinates (X, Y) of the object 902 . Figure 10A In the image processor, based on the images taken by lens modules 804 and 806, lens modules 806 and 808, lens modules 808 and 810, and lens modules 810 and 804, four possible positions 1001, 1002, 1003, and 1004 are obtained. Figure 10B As shown, the first position calculated by lens modules 804 and 806 is 1001 and 1003, the second position calculated by lens modules 806 and 808 is 1001, the third position calculated by lens modules 808 and 810 is 1001 and 1002, and the fourth position calculated by lens modules 810 and 804 is 1001 and 1004. At this point, the image processor takes the intersection of the first, second, third, and fourth positions (i.e., 1001) as the position of object 902, maps the position of object 902 to the corresponding button on control panel 802, and then instructs control panel 802 to trigger the button. At this point, the buttons corresponding to positions 1002, 1003, and 1004 (if any) are not triggered.

[0039] The above description is based on an example of four lens modules, but elevator control systems including three, five or more lens modules are also included in the spirit and scope of the present disclosure. Figure 8 and Figure 9The elevator control system 800 includes lens modules 804, 806, and 808, but does not include lens module 810. The image processor calculates the first position of object 902 from lens modules 804 and 806, and calculates the second position of object 902 from lens modules 806 and 808. The intersection of the first and second positions is used as the position of object 902, and the position of object 902 is mapped to a button on the control panel 802 to command the control panel 802 to trigger the button.
