Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0046] Those skilled in the art can understand that Figure 2 the structure shown in the figure does not constitute a limitation on the elevator, and it may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0047] As Figure 2 shown, the memory 1005, as a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and an elevator floor selection program based on digital imaging.

[0048] In Figure 2 the elevator shown in the figure, the network interface 1004 is mainly used for data communication with other devices; the interaction device 1003 is mainly used for data interaction with users; the processor 1001 and the memory 1005 in the elevator of the present invention may be arranged in the elevator. The elevator calls the elevator floor selection program based on digital imaging stored in the memory 1005 through the processor 1001 and executes the elevator floor selection method based on digital imaging provided by the embodiments of the present invention.

[0049] The embodiments of the present invention provide an elevator floor selection method based on digital imaging. Referring to Figure 3 , Figure 3 is a schematic flowchart of the first embodiment of an elevator floor selection method based on digital imaging of the present invention.

[0050] In this embodiment, applied to an elevator control device, the elevator control device is provided with an optical information processing unit and a target lens. The elevator floor selection method based on digital imaging includes:

[0051] Step S1: Obtain the optical information image of the target lens collected by the optical information processing unit. The first outer surface of the target lens is used to receive the image light information of the elevator user during the elevator floor selection process. The first outer surface is the outer surface corresponding to the end of the two outer surfaces of the target lens that is far from the optical information processing unit.

[0052] In this embodiment, the target lens is embedded on the control box inside the elevator car. The elevator can be provided with a light source to ensure that the optical information processing unit can receive the optical information image. The optical information processing unit here refers to a component that converts optical signals into electrical signals, which can be a Charge-Coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS). Specifically, the light information here can include the user's gestures, fingerprints, and face information. Specifically, the user's fingerprint is specifically obtained when the user places a finger at a preset distance from the target lens. Specifically, the optical information processing unit obtains the light incident from the target lens and converts the optical signal into an electrical signal to obtain the optical information image.

[0053] Step S2: Calculate the correlation coefficient according to the optical information image and the preset optical information template image.

[0054] The number of preset optical information template images here is multiple, generally the number of users using the elevator. By extracting the same type of data in the optical information image and the preset optical information template image, the correlation coefficient is calculated. The correlation coefficient is used to indicate whether the optical information image is the same as the preset optical information template image. Of course, it should be explained that not all data in the optical information image needs to be calculated for the correlation coefficient with the preset optical information template image.

[0055] Step S3: Determine whether to execute the response floor selection call corresponding to the preset optical information template image according to the correlation coefficient.

[0056] Preferably, the range of the correlation coefficient here is from 0 to 1. When the optical information image is the same as the preset optical information template layout, the correlation coefficient here is 1; when the optical information image is completely incoherent with the preset optical information template layout, the correlation coefficient here is 0; when there is partial identity between the optical information image and the preset optical information template layout, the correlation coefficient here is greater than 0 and less than 1. In this embodiment, a correlation coefficient threshold is set, and the correlation coefficient is compared with the threshold. Optionally, when the correlation coefficient is greater than or equal to the correlation coefficient threshold, it is determined to execute the response layer selection call corresponding to the preset optical information template image; when the correlation coefficient is less than the correlation coefficient threshold, it is determined not to execute the layer selection call.

[0057] In this embodiment, by acquiring the optical information image of the target lens collected by the optical information processing unit, calculating the correlation coefficient based on the optical information image and the preset optical information template image, and determining whether to execute the response layer selection call corresponding to the preset optical information template image according to the correlation coefficient, compared with the solution of setting a control panel with multiple mechanical buttons, it does not require the user to spend time looking for the corresponding floor button during the layer selection process, and can effectively save the time when the elevator is in the layer selection stage, thereby improving the operating efficiency of the elevator.

[0058] Further, based on the first embodiment, a second embodiment of the elevator layer selection method based on digital imaging according to the present invention is proposed. In this embodiment, referring to Figure 4 , the step of calculating the correlation value of the correlation peak according to the optical information image and the preset optical information template image includes:

[0059] Step S21, determining the position coordinates of the first correlation peak in the optical information image according to the optical information image and the corresponding gradient algorithm;

[0060] In this embodiment, the gradient algorithm here can be to calculate the change amount of the light intensity value between two adjacent pixels. Of course, for an optical information image with a high number of pixels, the image can be compressed before determining the position coordinates of the first correlation peak. Optionally, in this embodiment, the gradient algorithm here can be an edge processing algorithm. The position coordinates of the first correlation peak specifically refer to the center coordinates of the first correlation peak;

[0061] Step S22, calculating the correlation coefficient according to the second correlation peak corresponding to the preset optical information template image, the first correlation peak, and the corresponding position coordinates.

[0062] Specifically, the range of the first correlation peak is determined according to the position coordinates and the area of the second correlation peak to ensure the accuracy of the calculation process. In this embodiment, since the preset optical information template may store information related to gestures, fingerprints, and faces, there will be second correlation peaks that occupy different numbers of image pixels. After determining the position range of the first correlation peak, the correlation coefficient with the second correlation peak is calculated.

[0063] In this embodiment, by using the optical information image and the corresponding gradient algorithm to determine the position coordinates of the first correlation peak in the optical information image, the position of the first correlation peak in the optical information image can be located, thereby improving the accuracy of calculating the correlation coefficient.

[0064] Further, the step of determining the position coordinates of the first correlation peak in the optical information image according to the optical information image and the corresponding gradient algorithm includes:

[0065] Calculate the gradient magnitudes in two directions of the optical information image according to the gradient algorithm to obtain the first gradient magnitude corresponding to the first direction and the second gradient magnitude corresponding to the second direction, where the first direction is perpendicular to the second direction;

[0066] Determine the target gradient magnitude corresponding to the gradient direction according to the gradient direction algorithm, the first gradient magnitude, and the second gradient magnitude;

[0067] Specifically, the formula for calculating the gradient magnitude is as follows:

[0068]

[0069] Here, g(x, y) is the gradient magnitude, f(x, y) is the optical information image, and here are the partial derivatives in the X and Y directions respectively.

[0070] In addition, the formula for calculating the gradient direction is as follows:

[0071] θg = arctan(Gx, Gy)

[0072] Here, θg is the gradient direction.

[0073] Determine the position coordinates in the optical information image according to the target gradient magnitude.

[0074] Specifically, the first correlation peak is determined by comparing the gradient magnitude with a preset threshold range, and the position coordinates of the first correlation peak are determined.

[0075] Further, the step of calculating the correlation coefficient according to the first correlation peak and the second correlation peak corresponding to the preset optical information template image includes:

[0076] Calculate the cross - correlation coefficient based on the first correlation peak and the second correlation peak;

[0077] Calculate the first autocorrelation coefficient corresponding to the first correlation peak and the second autocorrelation coefficient corresponding to the second correlation peak respectively;

[0078] Determine the correlation coefficient based on the cross - correlation coefficient, the first autocorrelation coefficient and the second autocorrelation coefficient.

[0079] Specifically, referring to Figure 5 , Figure 5 which is a diagram of the correlation peak algorithm. The calculation formula of the correlation coefficient is as follows:

[0080]

[0081] Here, ρ is the correlation coefficient, J(x,y) here is the pixel value corresponding to the first correlation peak, and J(x,y) here is the pixel value corresponding to the second correlation peak.

[0082] In this embodiment, when the correlation coefficient is greater than or equal to the threshold, control the elevator to select the floor corresponding to the correlation coefficient greater than or equal to the threshold as the registration information; when the correlation coefficient is less than the threshold, stop the elevator from selecting a floor, or prompt that the floor selection input is incorrect.

[0083] In this embodiment, by calculating the correlation coefficient to determine whether there is a match, the accuracy of the matching recognition result of the correlation peak can be improved algorithmically.

[0084] Further, based on the first embodiment or the second embodiment, a third embodiment of the elevator floor selection method based on digital imaging is proposed. In this embodiment, before the step of determining whether to execute the response floor selection call corresponding to the preset optical information template image according to the correlation coefficient, it further includes:

[0085] Associate the user information with the preset optical information template image, and the user information includes the user's floor information.

[0086] Specifically, for elevator users in an office building, different users have different office areas. For example, A, B, C, and D respectively correspond to the elevator stops at the 16th, 17th, 18th, and 19th floors. The user information is associated with the preset optical information template image. In actual matching, the matching is performed according to the height order of the floors. Optionally, the management personnel can also independently set a fixed matching order.

[0087] In this embodiment, by performing the matching in a predetermined order, it can ensure that the floor selection operation can be completed on behalf of the user, improving the accuracy of the floor selection process.

[0088] Further, the number of the preset optical information template images is multiple, and the correlation coefficient corresponds to the preset optical information template image one by one. Refer to Figure 6 , the step S3 may include:

[0089] Step S31, when there is a correlation coefficient greater than or equal to the threshold, control the elevator to select the floor corresponding to the correlation coefficient greater than or equal to the threshold as the registration information;

[0090] Step S32, when there is no correlation coefficient greater than or equal to the threshold, stop the elevator from selecting a floor.

[0091] In addition, it should be noted that when there are more than one correlation coefficients greater than or equal to the threshold, select the floor corresponding to the highest correlation coefficient.

[0092] Specifically, from the perspective of protecting personal privacy, some elevator passengers are not willing to let outsiders know the building they arrive at. After controlling the elevator to select the floor corresponding to the correlation coefficient greater than or equal to the threshold as the registration information, it further includes:

[0093] Display the prompt color corresponding to the registration information;

[0094] It should be noted that, refer to Figure 7 , Figure 7 is a schematic diagram of the floor selection of the elevator operation box, and the floor number after the floor selection is not displayed inside the car. That is, the common prompts including numbers such as: F12, F13, and F14, etc. When reaching the corresponding floor, the prompt color in the car flashes or disappears, so as to prompt the user to reach the corresponding floor. It should be noted that this prompt method does not directly prompt the current floor selection situation. Only users on the same floor can determine the color corresponding to their floor. During the elevator floor selection process, users can determine whether the elevator will reach their floor according to the displayed color after entering the elevator car, thus realizing the avoidance of privacy leakage while further improving the efficiency of elevator floor selection. In this embodiment, in fact, there is no limitation on the mechanical buttons on the control box. For the floors where the parking lot is located, the first floor, etc., corresponding mechanical buttons can be set. Further, there may be a difference in at least one of color, saturation, and lightness between the two colors. Further, for too many floors, specific patterns can be selected to replace the prompt color to indicate the reached floor.

[0095] Further, the surface of the target lens includes a first region and a second region, and the surface roughness between the first region and the second region is different.

[0096] Optionally, the first region is the central region of the target lens surface, and the second region is the edge region of the target lens surface. Using this method can increase the volume of the lens while avoiding the situation of low quality of the light generated by the user.

[0097] In addition, an embodiment of the present invention further provides an elevator floor selection device based on digital imaging, which is applied to an elevator control device. The elevator control device is provided with an optical information processing unit and a target lens. The elevator floor selection device based on digital imaging includes:

[0098] An acquisition module, configured to acquire an optical information image of the target lens collected by the optical information processing unit.
