[0057] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0058] In one exemplary embodiment, such as Figure 1 As shown, a vehicle defrosting method is provided. Taking the application of this method to computer equipment as an example, the specific steps include:

[0059] Step 101: Obtain the image of the car window.

[0060] Specifically, it uses cameras or sensors to capture real-time images of the car windows.

[0061] Step 102: When a frost-covered area is detected in the window image, determine the frost thickness and location information of the frost-covered area.

[0062] Specifically, image processing techniques, such as edge detection and color analysis, are used to identify frosted areas in an image and estimate the thickness of the frosting.

[0063] Step 103: Determine the target focal point of the laser based on the location information of the frosted area.

[0064] Specifically, in step 102, the frosted areas in the car window image have been identified using image processing technology, and the location information of these areas has been determined. This information may include the boundary coordinates and size of the frosted areas. Based on the location information of the frosted areas, the target focal point of the laser needs to be calculated. This focal point should be the center of the frosted area or a key location so that the laser can evenly illuminate the entire frosted area.

[0065] When determining the target focal point, the characteristics and parameters of the laser, such as the laser beam diameter and divergence angle, must also be considered. These parameters will affect the range and accuracy of the laser's illumination, and therefore need to be adjusted according to the actual situation. After determining the target focal point, calibration and positioning operations may be required to ensure that the laser can accurately illuminate the target location. This may require the use of auxiliary equipment, such as laser rangefinders and reflectors. Finally, based on the calculated target focal point, the laser's direction is set so that it can accurately illuminate the frosted area. This step may require adjusting the laser's angle and position.

[0066] Step 104: Determine the target energy value of the laser based on the current environmental temperature and the frost thickness of the frost area.

[0067] Specifically, the current environmental temperature is obtained in real time because temperature affects the hardness and thickness of frost, thereby affecting the energy required for laser defrosting. In step 102, the frost thickness of the frost area has been determined. This information is crucial for determining the target energy value of the laser, as different thicknesses of frost require different energy to remove.

[0068] When determining the target energy value, the energy range of the laser also needs to be considered. The energy output of the laser should be within its safe operating range to avoid damage to the vehicle window or other parts.

[0069] Based on the current environmental temperature, frost thickness, and characteristics of the laser, a target energy value needs to be calculated. This value should ensure that the laser effectively removes frost without causing overheating or damage to the surrounding area. Finally, based on the calculated target energy value, the parameters of the laser, such as power and pulse width, need to be adjusted to ensure that its output energy matches the target energy value.

[0070] Step 105: Control the laser to perform defrosting treatment on the frost area based on the target focal point and target energy value.

[0071] Specifically, before performing the defrosting treatment, it is necessary to ensure that the laser is in normal working condition. This includes checking the various parameter settings of the laser, such as wavelength, power, pulse frequency, etc., to ensure they match the target energy value. Using the positioning or mechanical arm of the laser, the laser beam is precisely aimed at the target focal point calculated earlier. This is a key step to ensure that the laser energy can be concentrated on the frost area.

[0072] Based on the target energy value, set the pulse energy, pulse width, and other parameters of the laser. These parameters will directly affect the effectiveness of the laser in removing frost. It is necessary to ensure that the energy of the laser pulse is high enough to effectively melt or vaporize the frost, but not too high to avoid damaging the vehicle window glass. Once all the parameters are set and the laser is aimed at the target focal point, the defrosting operation can begin. The laser will emit high-energy laser pulses that act on the frost area. The energy of the laser will be absorbed by the frost, causing it to melt or vaporize, thereby achieving the defrosting effect. During the defrosting process, the running state of the laser and the defrosting effect need to be monitored in real time. If the defrosting effect is poor or the laser appears abnormal, the parameters should be adjusted or the operation should be stopped in time to ensure the safety and effectiveness of the defrosting process. When the frost area is completely cleared, the defrosting operation is completed. At this time, the laser can be turned off, and necessary follow-up processing such as cleaning the melted water stains can be performed.

[0073] In the above vehicle defrosting method, the camera captures images of the glass surface and identifies the pattern of frost or ice through image processing techniques. The radar emits microwaves or other types of waves that reflect back when they encounter ice points. By measuring the time and direction of the reflected waves, the precise location of the ice points, including their three-dimensional coordinates, can be determined. The position of the laser focal point is changed by adjusting the parameters of the laser, such as the lens position, beam angle, etc. Ensuring that the laser focal point can accurately fall on the frost layer is the key to achieving effective removal. According to the information provided by the camera, radar, and temperature sensing device, the power of the laser is intelligently adjusted. This can ensure that the laser removes frost and ice without causing damage to the glass or other parts. The entire process does not require human intervention. After starting the vehicle, the driver does not need to wait for the water tank temperature to rise to a certain standard before defrosting. Frost removal is automatically performed according to actual conditions, which not only improves the efficiency of frost removal but also increases the comfort and safety of the driver. By monitoring and adjusting the laser parameters in real time, frost and ice on the glass can be effectively removed in the shortest time, while avoiding any damage to the vehicle.

[0074] In one exemplary embodiment, the laser includes a laser generating component and a focusing adjustment mirror group; according to the target focal point and the target energy value, the laser controls the defrosting treatment of the frosting area, including:

[0075] According to the target focal point, the target position of the focusing adjustment mirror group between the laser generating component and the vehicle window is determined.

[0076] Wherein, when the focusing adjustment mirror group is in the target position, the laser beam emitted by the laser generating component falls on the target focal point after being adjusted by the focusing adjustment mirror group.

[0077] Specifically, according to the previously calculated target focal point (which is the center point of the frosting area that needs to be irradiated by the laser), the target position of the focusing adjustment mirror group between the laser generating component and the vehicle window needs to be determined.

[0078] When the focusing adjustment mirror group is in this target position, the laser beam emitted by the laser generating component will be accurately adjusted by the focusing adjustment mirror group and finally accurately fall on the target focal point. In this way, the energy of the laser can be maximally concentrated in the frosting area, improving the defrosting efficiency. In the case where the focusing adjustment mirror group is placed in the target position, the laser generating component is controlled to emit a laser beam with a target energy value for defrosting treatment of the frosting area. Once the focusing adjustment mirror group is accurately placed in the target position, the laser generating component is controlled to emit a laser beam with a previously determined target energy value. This target energy value is carefully calculated to ensure that the laser beam has enough energy to melt or vaporize the frost while not causing damage to the vehicle window glass or other surrounding materials.

[0079] Specifically, as Figure 2As shown, the focus adjustment lens group includes a convex lens for adjusting the position of the laser beam in the z-axis, a first reflective lens for adjusting the position of the laser beam in the x-axis, and a second reflective lens for adjusting the position of the laser beam in the y-axis.

[0080] Wherein, the laser beam emitted by the laser 1 will be used to heat and eventually melt or vaporize the frost on the glass surface. The convex lens 2 is responsible for adjusting the focal point position of the laser beam in the z-axis (i.e. the direction of laser propagation). By moving the convex lens forward and backward, the focal length of the laser beam can be changed, ensuring that the laser focal point can accurately fall on the icing point. There are two reflective lenses in total, one for adjusting the position of the laser beam in the x-axis (reflective lens 31) and the other for adjusting the position of the laser beam in the y-axis (reflective lens 32). By rotating these two reflective lenses, the offset of the laser beam in the horizontal plane (x-axis) and the vertical plane (y-axis) can be accurately controlled, ensuring that the laser focal point is aligned with the icing point. There is also a temperature sensor to monitor the temperature of the laser focal point in real time. This information is crucial to prevent local overheating caused by prolonged laser irradiation. If the temperature is too high, the laser power will be reduced accordingly to avoid damage to the glass; conversely, if the temperature is too low, the laser power may need to be increased to ensure that the frost can be effectively melted. The whole process is automatically managed through an intelligent control algorithm. According to the position, size and shape of the icing point, the positions of the convex lens and the reflective lenses, as well as the power of the laser, are dynamically adjusted to achieve efficient and accurate defrosting.

[0081] In summary, this laser defrosting achieves efficient, safe and automated removal of frost on the glass surface by precisely controlling the focal point position and power of the laser beam, as well as real-time monitoring of the focal point temperature. This not only improves the driving safety of the vehicle, but also enhances the comfort of the driver and passengers.

[0082] Further, as shown in Figure 3 According to the target focal point, the target position of the focus adjustment lens group between the laser generating assembly and the vehicle window is determined, including:

[0083] Step 301: According to the target focal point, adjust the position of the focus adjustment lens group between the laser generating assembly and the vehicle window, and during the adjustment process, identify whether the laser beam is located within the frosting area.

[0084] First, according to the coordinates of the target focal point, the position of the focus adjustment lens group (including the convex lens and the two reflective lenses) between the laser generating assembly and the vehicle window will be adjusted. During the adjustment process, it will constantly identify whether the laser beam is located within the frosting area. This is usually achieved through cameras, sensors or other optical detection devices, which can monitor the position of the laser beam and its relative relationship with the frosting area in real time.

[0085] Step 302: If yes, the position of the focus adjustment lens group is determined as the target position.

[0086] Once it detects that the laser beam has accurately landed on the frosted area and that the laser focus coincides with or is sufficiently close to the target focus point, it determines the position of the focusing adjustment lens assembly as the target position. At this position, the focusing adjustment lens assembly can precisely adjust the laser beam emitted by the laser generating component to the target focus point, thereby ensuring that laser energy is concentrated to the maximum extent in the frosted area for efficient defrosting.

[0087] These two steps precisely position the focusing adjustment lens assembly, ensuring the laser beam accurately illuminates the target focal point of the frosted area. This precise positioning not only improves the efficiency and effectiveness of defrosting but also avoids wasting laser energy and potential damage to surrounding areas. The entire process is automated, greatly reducing the need for manual intervention and improving operational convenience and safety.

[0088] In an exemplary embodiment, if there are multiple target focal points, the laser is controlled to perform defrosting on the frosted area according to the target focal points and the target energy value, including: controlling the laser to perform defrosting on the frosted area according to the defrosting priority of each target focal point and the target energy value corresponding to each target focal point.

[0089] Specifically, different target focal points may be assigned different defrosting priorities based on factors such as the severity of frost, its impact on the driver's vision, or safety considerations. For example, frost located in front of the driver's line of sight may have a higher priority because it has a greater impact on driving safety. Each target focal point may have a corresponding target energy value. This value is set based on factors such as the thickness and density of the frost and the required melting speed. Thicker frost or areas requiring rapid removal may be assigned a higher target energy value. The laser is intelligently controlled according to the aforementioned defrosting priorities and target energy values. The laser first aims at the highest priority target focal point and emits laser light at the corresponding target energy value for defrosting. After defrosting one point, the laser moves to the next target focal point according to the priority list and repeats the process. During defrosting, the temperature change and defrosting effect of the frost area are monitored in real time. If the defrosting effect at a certain point is found to be poor, or if the temperature sensor detects an anomaly, the laser power can be dynamically adjusted or the target energy value can be reallocated.

[0090] In this way, laser defrosting can efficiently treat multiple frosted areas, ensuring maximum defrosting effect within a limited time while guaranteeing driving safety. This intelligent approach not only improves defrosting efficiency but also reduces driver distraction, enhancing the overall driving experience.

[0091] Furthermore, the method also includes: for each target focal point, determining whether the target focal point falls within the set field of view; if so, determining the defrosting priority of the target focal point as the first priority; if not, determining the defrosting priority of the target focal point as the second priority.

[0092] The first priority is higher than the second priority.

[0093] For each target focal point, it will determine whether that point is within a preset field of view. This field of view can be set based on the driver's normal line of sight, the vehicle's safe driving requirements, or other relevant factors.

[0094] If the target focal point falls within the designated field of vision, then the defrosting priority for that point will be set to first priority. This means that these points are crucial to the driver's visibility and safe driving, and therefore require priority defrosting.

[0095] If the target focal point is not within the designated field of view, then the defrosting priority for that point will be set to second priority. Although these points also require defrosting, they are not the most urgent and can be defrosted after the first priority points have been dealt with.

[0096] By using this field-of-view-based prioritization method, the laser can more intelligently allocate the defrosting sequence, prioritizing the frosted areas that have the greatest impact on the driver's visibility and safe driving. This method not only improves defrosting efficiency and safety but also better adapts to different driving environments and weather conditions.

[0097] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
