[0037] Figure 8 It is a block diagram of a vehicle shown according to an exemplary embodiment. Detailed implementation

[0038] In order to enable those of ordinary skill in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present disclosure described here can be implemented in an order different from those illustrated or described here. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0040] Figure 1 It is a block diagram of a glass heating system shown according to an exemplary embodiment, as Figure 1As shown, the heating system 100 of the glass according to the embodiments of the present disclosure includes a glass body 1, a camera module 2, and a heating wire 3. Among them, the camera module 2 includes a first camera 21 and a second camera 22, and the field of view area of the first camera 21 is located within the field of view area of the second camera 22. It can be understood that, compared with the second camera 22, the field of view area of the first camera 21 is narrower, that is, the first camera 21 is a narrow-field camera, and the second camera 22 is a wide-field camera.

[0041] As Figure 2 shown, the overlapping area between the field of view area of the first camera 21 and the glass body 1 is the first area, and the arrangement position of the heating wire 3 on the glass body 1 does not include the first area. The boundary line of the first area is S1.

[0042] It should be noted that the arrangement position of the heating wire 3 on the glass body 1 may include any area of the glass body 1 except the first area, and no further limitation is made here.

[0043] It can be understood that camera manufacturing errors, installation errors, etc. will cause horizontal errors ±dH and vertical errors ±dV in the field of view area of the camera. The field of view area of the first camera 21 is calibrated based on the horizontal error ±dH1 and vertical error ±dV1 of the first camera 21, and the field of view area of the second camera 22 is calibrated based on the horizontal error ±dH2 and vertical error ±dV2 of the second camera 22. No further limitation is made on the calibration method.

[0044] For example, the horizontal field of view angle of the first camera 21 is H1 + 2*dH1, and the vertical field of view angle is V1 + 2*dV1, where H1 is the horizontal field of view angle of the first camera 21 before calibration, and V1 is the vertical field of view angle of the first camera 21 before calibration. The field of view area of the first camera 21 is determined based on the horizontal field of view angle and vertical field of view angle of the first camera 21.

[0045] It should be noted that no further limitation is made on the glass body 1. For example, the glass body 1 may include one or more pieces of glass. For example, the glass body 1 may include laminated glass. For example, taking the application scenario as a vehicle, the glass body 1 may include the front windshield, side window glass, rear windshield, sunroof glass, etc. of the vehicle.

[0046] It should be noted that there are no excessive restrictions on the arrangement position of the heating wire 3 on the glass body 1. For example, the heating wire 3 is arranged on the inner surface or the intermediate layer of the glass body 1. For example, the glass body 1 includes surfaces 1 to 4 arranged in the order from outside to inside, where surfaces 1 and 2 are the surfaces of the outer glass of the glass body 1, and surfaces 3 and 4 are the surfaces of the inner glass of the glass body 1. The inner surface of the glass body 1 may include surface 4, and the intermediate layer of the glass body 1 may include surfaces 2 and 3. The intermediate layer may include an organic polymer interlayer, such as a PVB (polyvinyl butyral) interlayer.

[0047] It should be noted that if the heating wire 3 is arranged on the intermediate layer of the glass body 1, the first region refers to the overlapping region between the field of view region of the first camera 21 and the intermediate layer of the glass body 1. Or, if the heating wire 3 is arranged on the inner surface of the glass body 1, the first region refers to the overlapping region between the field of view region of the first camera 21 and the inner surface of the glass body 1.

[0048] It should be noted that there are no excessive restrictions on the material of the heating wire 3. For example, it may include silver paste material, enameled wire, tungsten wire material, etc. For example, if the heating wire 3 is arranged on the inner surface of the glass body 1, the material of the heating wire 3 includes silver paste material. If the heating wire 3 is arranged on the intermediate layer of the glass body 1, the material of the heating wire 3 includes enameled wire and tungsten wire material.

[0049] It should be noted that there are no excessive restrictions on the position of the camera module 2. For example, the camera module 2 is arranged on the inner surface of the glass body 1 or the surrounding area of the glass body 1. For example, the camera module 2 is connected to the mounting bracket, and the mounting bracket is arranged on the inner surface of the glass body 1. For example, each camera in the camera module 2 is arranged horizontally, and the optical axes of each camera are parallel.

[0050] It should be noted that there are no excessive restrictions on the camera module 2. For example, in addition to the first camera 21 and the second camera 22, the camera module 2 may further include other cameras. For example, taking the application scenario as a vehicle, the camera module 2 is a component of an ADAS (Advanced Driver Assistance System). The ADAS can perform automatic emergency braking, lane keeping assistance, traffic sign recognition, adaptive cruise, etc. based on the images collected by the camera module 2.

[0051] The heating system for glass provided by the embodiments of the present disclosure includes a glass body, a camera module, and heating wires. Among them, the camera module includes a first camera and a second camera. The field of view area of the first camera is located within the field of view area of the second camera. The overlapping area between the field of view area of the first camera and the glass body is the first area. The arrangement position of the heating wires on the glass body does not include the first area. Thus, compared with the related art where the heating wires uniformly cover the glass body, resulting in the diffraction phenomenon of light on the glass body and then affecting the imaging quality of the first camera, in this solution, the arrangement position of the heating wires can avoid the first area, that is, avoid the overlapping area between the field of view area of the first camera and the glass body, so that the diffraction phenomenon of light does not occur in the first area, thereby avoiding the influence of the diffraction phenomenon of light on the imaging quality of the first camera, helping to improve the imaging quality of the first camera. Especially in the scene with lights at night, the first camera has good imaging quality for lights and no obvious light spikes. Especially in the application scenario where the camera module is used for intelligent driving, the safety of intelligent driving is improved.

[0052] Based on any of the above embodiments, as Figure 2 shown, the overlapping area between the field of view area of the second camera 22 and the glass body 1 is the second area. The arrangement position of the heating wires 3 on the glass body 1 includes a target area, where the target area is the area in the second area except the first area. The boundary line of the second area is S2.

[0053] It should be noted that the target area and the first area constitute the second area. If the heating wires 3 are arranged on the intermediate layer of the glass body 1, the second area refers to the overlapping area between the field of view area of the second camera 22 and the intermediate layer of the glass body 1.

[0054] Thus, the arrangement position of the heating wires includes the target area, so that the heating wires can defog and defrost the target area, that is, the heating wires can defog and defrost a partial overlapping area between the field of view area of the second camera and the glass body, thereby avoiding the influence of glass fogging and frosting on the imaging quality of the second camera, helping to improve the imaging quality of the second camera. Especially in the application scenario where the camera module is used for intelligent driving, the safety of intelligent driving is improved.

[0055] In one implementation, the heating wires 3 are arranged on the glass body 1 along a first direction and at a set interval d, that is, the heating wires 3 are uniformly arranged on the glass body 1 along the first direction.

[0056] It should be noted that there are no excessive restrictions on the first direction. For example, as Figure 2 shown, the first direction is horizontal (lateral direction).

[0057] It should be noted that there are no excessive restrictions on the set interval d. For example, the set interval d is greater than or equal to 15 millimeters.

[0058] In some examples, the distance of the second region in the second direction is the target distance L, and the number of heating wires 3 arranged along the first direction in the target region is less than or equal to the target ratio, where the target ratio is the ratio of the target distance L to the set interval d, and the first direction is perpendicular to the second direction. That is, the number of heating wires 3 arranged along the first direction in the target region ≤ L / d.

[0059] For example, as Figure 2 shown, the first direction is horizontal and the second direction is vertical (perpendicular direction).

[0060] In one embodiment, at least one bent portion of the heating wire 3 is a semi-circular arc, which can reduce the influence of the bent portion of the heating wire 3 on the diopter of the glass and avoid optical distortion of the glass, especially suitable for the application scenario of the front windshield of a vehicle.

[0061] In some examples, the bent portions of the heating wire 3 in the target region are semi-circular arcs. For example, as Figure 2 shown, all wire portions of the bent portions S3, S4, S6, S7 of the heating wire 3 are located in the target region, and partial wire portions of the bent portions S5, S8, S9 of the heating wire 3 are located in the target region. S3 to S9 are all semi-circular arcs. Thus, in this solution, the bent portions of the heating wire in the target region are semi-circular arcs, which can avoid optical distortion of the glass in the target region, help improve the imaging quality of the second camera, especially in the application scenario where the camera module is used for intelligent driving, and improve the safety of intelligent driving.

[0062] It should be noted that the bent portions of the heating wire 3 in the regions other than the target region can be semi-circular arcs or not, and no excessive limitation is made here.

[0063] In some examples, the heating wires 3 are arranged on the glass body 1 along the first direction at a set interval, and the radius of the semi-circular arc is half of the set interval d, that is, the radius of the semi-circular arc is d / 2. For example, as Figure 2 shown, the radius of the semi-circular arcs of S3 to S9 is d / 2.

[0064] In some examples, the bent portion of the heating wire 3 in the third region is a semi-circular arc, where the third region is located within the target region, and the distance between the position point in the third region and the boundary line S2 of the second region is greater than or equal to a set threshold. Thus, the position point in the third region is far from the boundary line of the second region, that is, the third region is the central region of the target region. The third region has a greater impact on the imaging quality of the second camera. In this solution, the bent portion of the heating wire in the third region is a semi-circular arc, which can avoid optical distortion of the glass in the third region and help improve the imaging quality of the second camera. Especially in the application scenario where the camera module is used for intelligent driving, the safety of intelligent driving is improved.

[0065] It should be noted that the set threshold is not overly limited. For example, it can be 5 millimeters. The bent portion of the heating wire 3 in the region other than the third region can be a semi-circular arc or not, and this is not overly limited here.

[0066] For example, as Figure 3 shown, all the wire portions of the bent portions S3, S4, S7 of the heating wire 3 are located within the third region, and some wire portions of the bent portions S5, S6, S8, S9 of the heating wire 3 are located in the region of the target region other than the third region. S3, S4, S7 are semi-circular arcs, and S5, S6, S8, S9 are not semi-circular arcs.

[0067] It should be noted that Figures 1 to 2 the heating system of the glass shown is only an example of the heating system of the glass in the embodiments of the present disclosure, and is not a limitation on the heating system of the glass in the embodiments of the present disclosure. Figures 1 to 3 The heating system of the glass shown is applicable to Figures 4 to 6 the arrangement method of the heating wire shown.

[0068] Figure 4 is a flowchart of an arrangement method of a heating wire shown according to an exemplary embodiment. The camera module includes a first camera and a second camera, where the viewing area of the first camera is located within the viewing area of the second camera.

[0069] As Figure 4 shown, the arrangement method of the heating wire in the embodiments of the present disclosure includes the following steps.

[0070] S401, obtain the overlapping area between the viewing area of the first camera and the glass body as the first region.

[0071] It should be noted that the execution subject of the heating wire arrangement method in the embodiments of the present disclosure is an electronic device, including mobile phones, notebooks, desktop computers, vehicle-mounted terminals (such as vehicle-mounted wireless modules), smart home appliances, etc. The heating wire arrangement method in the embodiments of the present disclosure can be executed by the heating wire arrangement device in the embodiments of the present disclosure. The heating wire arrangement device in the embodiments of the present disclosure can be configured in any electronic device to execute the heating wire arrangement method in the embodiments of the present disclosure.

[0072] For example, as Figure 2 shown, the overlapping area between the field of view area of the first camera 21 and the glass body 1 is the first area, and the boundary line of the first area is S1.

[0073] It can be understood that camera manufacturing errors, installation errors, etc. will cause horizontal errors ±dH and vertical errors ±dV in the field of view area of the camera. The field of view area of the first camera is calibrated based on the horizontal error ±dH1 and vertical error ±dV1 of the first camera, and the field of view area of the second camera is calibrated based on the horizontal error ±dH2 and vertical error ±dV2 of the second camera. The calibration method is not limited in detail.

[0074] In one implementation, obtaining the field of view area of the first camera includes obtaining the horizontal error and vertical error of the first camera, calibrating the horizontal field of view angle of the first camera based on the horizontal error of the first camera, calibrating the vertical field of view angle of the first camera based on the vertical error of the second camera, and determining the field of view area of the first camera based on the horizontal field of view angle and vertical field of view angle of the first camera.

[0075] In some examples, the horizontal field of view angle of the first camera is H1 + 2*dH1, and the vertical field of view angle is V1 + 2*dV1, where H1 is the horizontal field of view angle of the first camera 21 before calibration, and V1 is the vertical field of view angle of the first camera 21 before calibration.

[0076] S402, determining that the arrangement position of the heating wire on the glass body does not include the first area.

[0077] It should be noted that the arrangement position of the heating wire on the glass body can include any area in the glass body except the first area, and no detailed limitation is made here.

[0078] The arrangement method of the heating wire provided by the embodiments of the present disclosure. The camera module includes a first camera and a second camera. Among them, the viewing area of the first camera is located within the viewing area of the second camera. The overlapping area between the viewing area of the first camera and the glass body is obtained as the first area, and it is determined that the arrangement position of the heating wire on the glass body does not include the first area. Thus, compared with the problem in the related art that the heating wire uniformly covers the glass body, resulting in the diffraction phenomenon of light on the glass body, which in turn affects the imaging quality of the first camera, in this solution, the arrangement position of the heating wire can avoid the first area, that is, avoid the overlapping area between the viewing area of the first camera and the glass body. Therefore, the diffraction phenomenon of light will not occur in the first area, so as to avoid the influence of the diffraction phenomenon of light on the imaging quality of the first camera, which helps to improve the imaging quality of the first camera. Especially in the scene with lights at night, the first camera has good imaging quality for the lights and there is no obvious light spike. Especially in the application scenario where the camera module is used for intelligent driving, the safety of intelligent driving is improved.

[0079] Figure 5 It is a flowchart of an arrangement method of a heating wire shown according to another exemplary embodiment.

[0080] As Figure 5 shown, the arrangement method of the heating wire in the embodiments of the present disclosure includes the following steps.

[0081] S501, obtain the overlapping area between the viewing area of the first camera and the glass body as the first area.

[0082] For the relevant content of step S501, reference can be made to the above embodiments and will not be elaborated here.

[0083] S502, obtain the overlapping area between the viewing area of the second camera and the glass body as the second area.

[0084] For example, as Figure 2 shown, the overlapping area between the viewing area of the second camera 22 and the glass body 1 is the second area, and the boundary line of the second area is S2.

[0085] S503, obtain the area in the second area except the first area as the target area.

[0086] S504, determine that the arrangement position of the heating wire on the glass body includes the target area.

[0087] It should be noted that the arrangement position of the heating wire on the glass body may include the target area in the glass body and the remaining areas other than the first area, and no more limitations are made here.

[0088] In one embodiment, the heating wires are arranged on the glass body along a first direction at a set interval d. The method further includes obtaining a plurality of candidate intervals at which the heating wires are arranged when the heating index of the target area meets the set conditions, and taking the maximum value among the plurality of candidate intervals as the set interval. Thus, when the heating index of the target area meets the set conditions, the maximum value among the plurality of candidate intervals can be taken as the set interval, that is, while meeting the heating requirements of the target area, the set interval can be set as large as possible, which can avoid the problem that two adjacent parts of the heating wires interfere with each other and come into contact, and helps to improve the safety and reliability of the heating wires.

[0089] It can be understood that when the arrangement interval of the heating wires is any one of the candidate intervals, the heating index of the target area meets the set conditions. There are no excessive limitations on the heating index and the set conditions, and different heating indexes can correspond to different set conditions. For example, when the heating index is the heating efficiency, the set conditions may include that the heating efficiency of the target area is greater than or equal to the set efficiency.

[0090] In one embodiment, the heating wires are arranged on the glass body along a first direction at a set interval. The method further includes obtaining the distance of the second area in the second direction as the target distance, where the first direction is perpendicular to the second direction, obtaining the ratio between the target distance and the set interval as the target ratio, and determining that the number of heating wires arranged along the first direction in the target area is less than or equal to the target ratio. Thus, the ratio between the distance of the second area in the second direction and the set interval can be considered to determine the number of heating wires arranged along the first direction in the target area, and the number of heating wires arranged along the first direction in the target area is less than or equal to the target ratio.

[0091] In one embodiment, at least one bent part of the heating wire is a semi - circle. The heating wires are arranged on the glass body along a first direction at a set interval d. The method further includes obtaining half of the set interval d as the radius of the semi - circle, that is, the radius of the semi - circle is d / 2, so as to realize the determination of the size of the semi - circle.

[0092] The arrangement method of the heating wire provided by the embodiments of the present disclosure obtains the overlapping area between the field of view area of the second camera and the glass body as the second area, obtains the area in the second area except the first area as the target area, and determines that the arrangement position of the heating wire on the glass body includes the target area. Thus, the arrangement position of the heating wire includes the target area, so that the heating wire can defog and defrost the target area, that is, the heating wire can defog and defrost a partial overlapping area between the field of view area of the second camera and the glass body, so as to avoid the influence of glass fogging and frosting on the imaging quality of the second camera, which helps to improve the imaging quality of the second camera. Especially in the application scenario where the camera module is used for intelligent driving, the safety of intelligent driving is improved.

[0093] Figure 6 It is a flowchart of an arrangement method of a heating wire shown according to another exemplary embodiment. As Figure 6 shown, the arrangement method of the heating wire in the embodiments of the present disclosure includes the following steps.

[0094] S601, obtain the overlapping area between the field of view area of the first camera and the glass body as the first area.

[0095] S602, obtain the overlapping area between the field of view area of the second camera and the glass body as the second area.

[0096] S603, obtain the area in the second area except the first area as the target area.

[0097] S604, determine that the arrangement position of the heating wire on the glass body includes the target area.

[0098] For the relevant content of steps S601 - S604, reference can be made to the above embodiments and will not be elaborated here.

[0099] S605, if the distance between the position point in the target area and the boundary of the second area is greater than or equal to the set threshold, divide the position point in the target area into the third area.

[0100] S606, determine that the bent part of the heating wire in the third area is a semi - circle arc.

[0101] It should be noted that there are no excessive limitations on the set threshold. For example, it can be 5 millimeters. The bent part of the heating wire in the area except the third area can be a semi - circle arc or not, and there are no excessive limitations here.

[0102] For example, as Figure 3As shown, all wire parts of the bent portions S3, S4, and S7 of the heating wire 3 are located within the third region, and some wire parts of the bent portions S5, S6, S8, and S9 of the heating wire 3 are located in regions other than the third region in the target region. It can be determined that S3, S4, and S7 are semi-circular arcs, and it can be determined that S5, S6, S8, and S9 are not semi-circular arcs.

[0103] For the arrangement method of the heating wire provided by the embodiment of the present disclosure, if the distance between the position point in the target region and the boundary of the second region is greater than or equal to the set threshold, the position point in the target region is divided into the third region, and the bent portion of the heating wire in the third region is determined to be a semi-circular arc. Thus, the third region is located within the target region and far from the boundary line of the second region, that is, the third region is the central region of the target region. The third region has a greater impact on the imaging quality of the second camera. In this solution, the bent portion of the heating wire in the third region is a semi-circular arc, which can avoid optical distortion of the glass in the third region and help improve the imaging quality of the second camera. Especially in the application scenario where the camera module is used for intelligent driving, the safety of intelligent driving is improved.

[0104] Figure 7 It is a block diagram of an arrangement device of a heating wire shown according to an exemplary embodiment. The camera module includes a first camera and a second camera, wherein the field of view region of the first camera is located within the field of view region of the second camera.

[0105] Refer to Figure 7 , the arrangement device 200 of the heating wire according to the embodiment of the present disclosure includes: an acquisition module 210 and an arrangement module 220.

[0106] The acquisition module 210 is configured to acquire the overlapping region between the field of view region of the first camera and the glass body as the first region;

[0107] The arrangement module 220 is configured to determine that the arrangement position of the heating wire on the glass body does not include the first region.

[0108] In an embodiment of the present disclosure, the arrangement module 220 is further configured to: acquire the overlapping region between the field of view region of the second camera and the glass body as the second region; acquire the region in the second region other than the first region as the target region; determine that the arrangement position of the heating wire on the glass body includes the target region.

[0109] In one embodiment of the present disclosure, the heating wires are arranged on the glass body along a first direction at a set interval. The arranging module 220 is further configured to perform: obtaining a plurality of candidate intervals at which the heating wires are arranged when the heating index of the target area meets the set conditions; and taking the maximum value among the plurality of candidate intervals as the set interval.

[0110] In one embodiment of the present disclosure, the heating wires are arranged on the glass body along a first direction at a set interval. The arranging module 220 is further configured to perform: obtaining the distance in a second direction of the second area as a target distance, where the first direction is perpendicular to the second direction; obtaining the ratio between the target distance and the set interval as a target ratio; and determining that the number of heating wires arranged along the first direction in the target area is less than or equal to the target ratio.

[0111] In one embodiment of the present disclosure, the arranging module 220 is further configured to perform: if the shortest distance between a position point in the target area and the boundary line of the second area is greater than or equal to a set threshold, dividing the position point in the target area into a third area; and determining that the bent portion of the heating wire in the third area is a semi-circular arc.

[0112] In one embodiment of the present disclosure, at least one bent portion of the heating wire is a semi-circular arc. The heating wires are arranged on the glass body along a first direction at a set interval. The arranging module 220 is further configured to perform: obtaining half of the set interval as the radius of the semi-circular arc.

[0113] Regarding the device in the above embodiments, the specific manners in which each module performs operations have been described in detail in the embodiments related to the method, and will not be elaborated herein.

[0114] The heating wire arrangement device provided by the embodiments of the present disclosure, the camera module includes a first camera and a second camera. Among them, the viewing area of the first camera is located within the viewing area of the second camera. The overlapping area between the viewing area of the first camera and the glass body is obtained as the first area, and it is determined that the arrangement position of the heating wire on the glass body does not include the first area. Thus, compared with the related art where the heating wire uniformly covers the glass body, resulting in the phenomenon of light diffraction on the glass body and further affecting the imaging quality of the first camera, in this solution, the arrangement position of the heating wire can avoid the first area, that is, avoid the overlapping area between the viewing area of the first camera and the glass body. Therefore, the phenomenon of light diffraction will not occur in the first area, so as to avoid the influence of the light diffraction phenomenon on the imaging quality of the first camera, which helps to improve the imaging quality of the first camera. Especially in the scene with lights at night, the first camera has a good imaging quality for the lights and there is no obvious light spike. Especially in the application scenario where the camera module is used for intelligent driving, the safety of intelligent driving is improved.

Thus, compared with the related art where the heating wire uniformly covers the glass body, resulting in the phenomenon of light diffraction on the glass body and further affecting the imaging quality of the first camera, in this solution, the arrangement position of the heating wire can avoid the first area, that is, avoid the overlapping area between the viewing area of the first camera and the glass body. Therefore, the phenomenon of light diffraction will not occur in the first area, so as to avoid the influence of the light diffraction phenomenon on the imaging quality of the first camera, which helps to improve the imaging quality of the first camera. Especially in the scene with lights at night, the first camera has a good imaging quality for the lights and there is no obvious light spike.
