[0012] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0013] The laser ice melting device and the laser ice melting method according to the present application will be described below with reference to the accompanying drawings.

[0014] The application provides a laser ice melting device capable of melting ice layers. The laser ice melting device comprises an imaging module, an energy emitting module, a lens module and a control module. The energy emitting module is capable of emitting an energy beam for melting the ice layer. The lens module is used for allowing the energy beam to pass through and focusing and collimating the energy beam. The focused and collimated energy beam can irradiate on the ice layer. The control module is electrically connected with the imaging module and the energy emitting module and is configured to acquire current image information of the ice layer in real time, turn on and keep the energy beam continuously irradiating when the current image information shows that the ice layer exists, and turn off the energy beam when the current image information shows that the ice layer does not exist. The laser ice melting device can effectively solve the technical problems of poor ice melting effect and poor ice melting positioning accuracy in the prior art.

[0015] In the embodiment, the output power range of the energy emitting module is 200 W-400 W.

[0016] The energy emitting module selects a specially designed 2 μm wavelength solid laser as a laser emitting source. The laser can stably output a 2 μm laser beam with adjustable power, meeting the energy requirement of ice layer melting. The output power range of the laser is 200-400 W. By adjusting the driving current and working parameters of the laser, the output power of the laser can be controlled to adapt to the ice melting requirements of ice layers with different thicknesses and materials. The energy emitting module further comprises a laser collimator which preliminarily collimates the laser emitted by the laser, so that the laser beam has good directivity.

[0017] In the embodiment, the wavelength allowed to pass through the lens module is 1900 nm-2100 nm.

[0018] The lens module adopts a high-quality 2 μm special lens. The material of the lens is specially selected, and the lens has high transmittance and good optical performance in the wavelength range of 1900 nm-2100 nm. The wavelength passing range of the lens can ensure efficient transmission of the 2 μm laser and reduce the interference of other wavelengths of light.

[0019] In the embodiment, the focal distance of the lens module is 30 m-50 m. By adjusting the relative position of the lens and the energy emitting module, the laser is focused to a specific area on the surface of the ice layer, so that the spot diameter of the laser on the surface of the ice layer reaches [a specific spot diameter value], thereby improving the energy density of the laser. The lens module further comprises a lens support for fixing the lens and enabling the lens to be adjusted in angle and position within a certain range to meet the requirements of different ice melting scenes.

[0020] The imaging module can adopt an imaging chip, such as a high-resolution and high-sensitivity CMOS or CCD imaging chip, which has a pixel resolution of [a specific pixel value] and can clearly capture the detailed information of the ice layer surface and the optical phenomena generated by the laser. The photosensitive range of the imaging chip covers the visible light to near-infrared waveband to ensure that the visible light image and the imaging information of the 2 pm laser of the ice layer can be captured simultaneously. The image processing unit of the imaging module adopts a high-performance digital signal processor (DSP) or a field programmable gate array (FPGA), and through the programming of specific image processing algorithm programs, the real-time processing of the images obtained by the imaging chip is realized. The image processing algorithm includes image enhancement, edge detection, image fusion and other functions, which can accurately fuse the imaging of the 2 pm laser with the visible light image and clearly display the position of the laser on the imaging screen. The imaging screen can be a portable liquid crystal display screen or an OLED display screen, which is connected with a mobile phone through a wireless communication module (such as Bluetooth, Wi-Fi, etc.) to transmit the processed images to the mobile phone screen for display, facilitating the observation of the operator.

[0021] The imaging chip can capture the image information of the ice layer surface. The imaging module further includes an image processing unit, which can process and analyze the images obtained by the imaging chip. The imaging module displays the background image on the mobile phone screen, facilitating the operator to observe the overall situation of the ice layer in real time. In addition, the imaging module can image the 2 pm laser on the visible light imaging screen, so as to find the position of the 2 pm laser in the time image. The imaging module adopts a high-resolution imaging chip, which can clearly capture the reflection, diffraction and other optical phenomena generated by the laser on the ice layer surface, and through a specific image processing algorithm, the imaging of the 2 pm laser is fused with the visible light image to realize the accurate positioning of the laser position.

[0022] In addition, before the ice melting operation is performed, the operator first installs the device of the present application in a suitable position to ensure that the laser of the energy emission module can accurately irradiate the ice layer surface that needs to be melted, and adjusts the position and angle of the lens module to make the laser focusing effect best.

[0023] When the energy emission module is started, the output power of the laser is set to a suitable value according to the actual situation of the ice layer, and the 2 pm ice melting laser is emitted. After the laser irradiates the ice layer surface, the ice layer gradually melts due to the absorption of the 2 pm laser by the ice layer, and reflection and diffraction phenomena occur on the ice layer surface.

[0024] The 2 pm ice melting laser passes through the 2 pm lens, and the lens focuses and collimates the laser to make the laser act on the ice layer with higher energy density, accelerating the melting process of the ice layer.

[0025] The imaging chip images the surface of the ice layer in real time, constantly capturing image information of the surface of the ice layer. The imaging chip transmits the acquired image data to the image processing unit, which first pre-processes the image, including denoising, brightness adjustment and the like, to improve the image quality.

[0026] The image processing unit transmits the pre-processed background image (i.e. the visible light image of the ice layer without laser imaging) to the mobile phone screen through the wireless communication module for display, so that the operator can observe the initial state and overall situation of the ice layer in real time.

[0027] The image processing unit processes the image containing 2pm laser imaging by using specific image recognition and fusion algorithms, fuses the imaging information of the laser with the background image, and clearly displays the position of the 2pm laser on the surface of the ice layer on the imaging screen. The operator can accurately determine the position of the laser and the ice melting effect by observing the fused image on the imaging screen or the mobile phone screen. If the laser position is found to be deviated or the ice melting effect is not ideal, the operator can adjust the emission angle and power of the energy emission module, and the position and angle of the lens module through the control device, to realize precise control of the ice melting process.

[0028] As shown in Figure 1 In this embodiment, a laser ice melting method is also proposed, which is applied to the laser ice melting device as described above, and the laser ice melting method comprises: S10: acquiring current image information of the ice layer in real time; S20: when the acquired current image information shows that the ice layer exists, starting and maintaining the continuous irradiation of the energy beam; S30: when the acquired current image information shows that the ice layer does not exist, turning off the energy beam.
