Description

Technical Field

[0001] This invention relates to the field of laser processing technology, and in particular to a method, apparatus, electronic device, and storage medium for engraving images. Background Technology

[0002] A laser engraving machine is a device that uses a laser beam to locally ablate or discolor the surface of a material. It is widely used for engraving patterns on materials such as wood, leather, paper, and metal. The common way to control a laser engraving machine is to generate and transmit a set of instructions (such as GCode) to control the switching on and off of the laser and its movement path, so as to realize the reproduction of the image content on the material surface.

[0003] In image engraving, a common practice is to convert the input image to grayscale, then scan the image pixels line by line, and generate corresponding GCode control instructions based on the grayscale values. However, when processing images containing a large number of pure white areas (i.e., areas that do not require processing), traditional methods still generate GCode instructions for motion paths for these areas, causing the laser head to make meaningless empty runs.

[0004] This practice not only severely impacts processing efficiency but also wastes equipment resources and reduces the lifespan of the laser machine. Summary of the Invention

[0005] This invention provides a method, apparatus, electronic device, and storage medium for engraving images, which significantly reduces invalid paths during laser engraving, improves overall processing efficiency, reduces frequent movement of the laser head in non-target areas, extends machine lifespan, and avoids waste of equipment resources.

[0007] Obtain the image to be sculpted;

[0008] The image to be sculpted is converted to grayscale to obtain the target image;

[0009] Based on the pixel data of the target image, a target region is determined; wherein, the target region is the image area in the target image that requires engraving.

[0010] A corresponding engraving path is generated based on the target area, and the laser device is controlled to perform engraving operations based on the engraving path to complete the image engraving.

[0015] The image engraving module is used to generate a corresponding engraving path based on the target area, and control the laser device to perform engraving operations based on the engraving path to complete the image engraving.

[0016] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0017] At least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores a computer program executable by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform a method for engraving an image as described in any embodiment of the present invention.

[0018] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement a method for engraving an image as described in any embodiment of the present invention.

[0019] The technical solution of this invention involves acquiring an image to be engraved; performing grayscale conversion on the image to obtain a target image; determining a target area based on the pixel data of the target image; generating a corresponding engraving path based on the target area; and controlling the laser device to perform the engraving operation according to the engraving path to complete the image engraving.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "current," "target," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] Example 1

[0032] Figure 1 This is a flowchart of a method for engraving an image according to Embodiment 1 of the present invention. This embodiment is applicable to the engraving of images. The method can be executed by an image engraving device, which can be implemented in hardware and / or software and can be configured in a device. For example, the device can be a backend server or other device with communication and computing capabilities. Figure 1 As shown, the method includes:

[0033] S110. Obtain the image to be sculpted.

[0034] The image to be engraved is in color.

[0035] In this solution, the image to be sculpted can be obtained from the database.

[0036] S120. Perform grayscale conversion on the image to be sculpted to obtain the target image.

[0037] The target image can be a grayscale image or a black and white image.

[0038] Specifically, the channel information of the image to be sculpted is processed using a specific formula to convert the image into a target image containing only brightness information.

[0039] S130. Determine the target region based on the pixel data of the target image; wherein the target region is the image region in the target image that needs to be engraved.

[0040] In this embodiment, the target region is the image region in the target image that requires engraving. The non-target region is the image region in the target image that does not require engraving.

[0041] In this scheme, the target image is divided into target region and non-target region based on the pixel data of the target image.

[0042] Specifically, the pixel data of the target image can be compared with a preset threshold to determine the target region and non-target regions. For example, assuming the preset threshold is 128, the region consisting of all pixels in the target image with pixel data less than or equal to 128 is determined as the target region; the region consisting of all pixels in the target image with pixel data greater than 128 is determined as the non-target region.

[0043] Furthermore, the pixel data of the target image can be compared point by point with a preset threshold row by row. Initially, target areas meeting the threshold requirements and non-target areas not meeting the requirements are selected from the entire row of pixel data. If a target area meeting the threshold requirements exists after the initial selection, the effective pixel range of that row is further reduced at both ends. By accurately removing invalid edge areas, the core effective pixels are ultimately retained, improving the accuracy of target area localization.

[0044] S140. Generate a corresponding engraving path according to the target area, and control the laser device to perform engraving operation according to the engraving path to complete the image engraving.

[0045] The carving path is based on pixel coordinates and is a continuous trajectory formed by the sequential connection of a series of ordered pixel positions.

[0046] In this scheme, a path planning algorithm is used to generate the corresponding carving path based on the pixel data arrangement order in the target area.

[0047] Among them, the laser equipment is a laser engraving machine, which can be used for engraving and processing of various materials.

[0048] Furthermore, the laser equipment can be turned on and off according to the engraving path, thereby completing the image engraving.

[0049] Optionally, the engraving path includes a lateral serpentine path or a bidirectional scanning path.

[0050] In this embodiment, the core logic of the bidirectional scanning path is: the laser head moves back and forth horizontally, and after completing each line scan, it only moves one line distance vertically before scanning the next line in the opposite direction. There is no need to run back to the starting point, thereby reducing unnecessary movement and improving processing efficiency.

[0051] In this scheme, the horizontal serpentine path is the specific path shape formed by limiting the fixed direction of bidirectional scanning to the horizontal (i.e., the horizontal direction parallel to the length / width direction of the engraved workpiece).

[0052] By using a lateral serpentine path or a bidirectional scanning path to control the laser equipment to perform engraving operations, image engraving is completed, significantly reducing invalid paths during the laser engraving process and improving overall processing efficiency.

[0053] Optionally, controlling the laser device to perform engraving operations according to the engraving path includes:

[0054] Generate carving control instructions based on the carving path;

[0055] According to the engraving control command, the laser device is controlled to perform an engraving operation that matches the engraving path.

[0056] Specifically, engraving control commands can use GCode control commands, which include two types: G0 and G1. G0 commands control the laser equipment to turn off the laser and only perform movement operations; G1 commands control the laser equipment to turn on the laser and perform processing operations.

[0057] In this solution, optimized GCode control instructions are generated based on the engraving path. These instructions can control the laser device to turn the laser on and off, and drive the laser device to move to the corresponding specified coordinates according to the position of the pixels in the target image.

[0058] By generating an engraving path based on the target area and controlling the laser equipment to perform engraving operations accordingly, invalid paths in the laser engraving process can be significantly reduced to improve overall processing efficiency, reduce the frequent movement of the laser head in non-target areas to extend machine life, avoid waste of equipment resources, and reduce the number of generated GCode instructions to optimize transmission and storage. Moreover, this solution is easy to integrate into existing image-to-GCode workflows and has good scalability.

[0059] In this plan, Figure 2 A schematic diagram of the target image provided in Embodiment 1 of this application, as shown below. Figure 2 As shown, the target image is large, with the white area representing the unprocessed path and the black area representing the region to be processed. Existing techniques typically begin acquiring pixels from the top left corner and then move or carve line by line.

[0060] In this embodiment, Figure 3 The optimized machine motion path provided in Embodiment 1 of this application is as follows: Figure 3 As shown, the green frame represents the image size, the red line represents the machine's idle path, and the black line represents the machine's processing path. Using the optimized image processing method, blank areas are skipped, and the shortest effective path is found, thus greatly improving processing efficiency.

[0061] The technical solution of this invention involves acquiring an image to be engraved; performing grayscale conversion on the image to obtain a target image; determining a target area based on the pixel data of the target image; generating a corresponding engraving path based on the target area; and controlling the laser device to perform the engraving operation according to the engraving path to complete the image engraving. By implementing this technical solution, invalid paths during laser engraving are significantly reduced, improving overall processing efficiency; frequent movement of the laser head in non-target areas is reduced, extending machine lifespan; waste of equipment resources is avoided; and the number of generated GCode instructions is reduced to optimize transmission and storage. Furthermore, this solution is easily integrated into existing image-to-GCode workflows and has good scalability.

[0062] Example 2

[0063] Figure 4 This is a schematic diagram illustrating a process of engraving an image according to Embodiment 2 of the present invention. The relationship between this embodiment and the above embodiments is a detailed description of the target area determination process. Figure 4 As shown, the method includes:

[0064] S410, Obtain the image to be sculpted.

[0065] S420. Perform grayscale conversion on the image to be sculpted to obtain the target image.

[0066] S430. Obtain the current row pixel data in the target image; wherein the current row pixel data contains a number of consecutively arranged pixel values.

[0067] In this embodiment, the current row refers to the row in the target image that is currently in the process of executing the judgment flow. For example, the current row can be the first row or the second row of the target image, depending on the current stage of the judgment process. The pixel data of the current row contains several consecutively arranged pixel values.

[0068] Furthermore, the pixel data of the current row in the target image is obtained through an image reading tool.

[0069] In this plan, Figure 5 A flowchart of the image engraving process provided in Embodiment 2 of this application is shown below. Figure 5 As shown, the pixels in the target image are analyzed line by line.

[0070] S440. Determine whether the current row pixel data is greater than a preset first threshold.

[0071] The first threshold is set according to the requirements of the engraved image; for example, the first threshold is set to 128.

[0072] In this scheme, the specific value of the current row pixel data is compared with a first threshold to determine whether the current row pixel data is greater than the first threshold.

[0073] S450. If not, then the target region corresponding to the current row is determined based on the comparison result between the current row pixel data and the preset second threshold; wherein the second threshold is less than or equal to the first threshold.

[0074] In this scheme, if the pixel data of the current row is greater than the first threshold, the continuous region composed of all pixels in the current row is determined as the non-target region corresponding to the current row.

[0075] In this embodiment, when parsing image pixels line by line, a Boolean variable `isWhiteRow` is set, initially set to false. Each row of pixels is scanned; if the grayscale value of all pixels in that row is greater than a first threshold, `isWhiteRow` is set to true. When `isWhiteRow == true`, that row is skipped, no processing instructions are generated, and the laser head of the laser device is directly moved to the starting position of the next row.

[0076] Specifically, such as Figure 5 As shown, when processing the target image, a white line (non-target area) filtering operation must be performed first: First, a first threshold is set, and then the pixel data of the current line is judged. If the pixel data of the current line is greater than the first threshold, the line is judged as a "white line". For the current line judged as a white line, it is skipped and not retained. Only the image content of the non-white line is processed to achieve effective screening and optimization of the target image.

[0077] The second threshold is set according to the requirements of the sculpted image. The second threshold is less than or equal to the first threshold.

[0078] Furthermore, if the current row pixel data is less than or equal to the first threshold, the current row pixel data is compared with the second threshold, and the target area corresponding to the current row is determined based on the comparison result between the current row pixel data and the second threshold.

[0079] Optionally, the target region is determined based on the comparison result between the current row pixel data and a preset second threshold, including:

[0080] The pixel values ​​in the current row of pixel data are judged point by point. If the currently judged pixel value is less than the second threshold, the pixel point corresponding to the currently judged pixel value is taken as the starting point of the target region in the current row.

[0081] Continue to judge the pixel values ​​after the starting point in the current row point by point. If the currently judged pixel value is less than the second threshold, the temporary endpoint of the current row is continuously updated until a pixel value greater than or equal to the second threshold is detected. Then, the update stops and the last endpoint in the temporary endpoint is taken as the endpoint of the target area in the current row.

[0082] The continuous region consisting of all pixels between the starting point and the ending point is determined as the target region corresponding to the current row.

[0083] Specifically, each pixel value in the current row of pixel data is evaluated point by point. If the currently evaluated pixel value is less than the second threshold, the pixel corresponding to the currently evaluated pixel value (the first valid pixel) is taken as the starting point of the target region in the current row. The process continues to evaluate the pixel values ​​following the starting point in the current row. If the currently evaluated pixel value is less than the second threshold, the temporary ending point of the current row is continuously updated until a pixel value greater than or equal to the second threshold is detected. At this point, the update stops, and the last ending point (the last valid pixel) in the temporary ending point is taken as the ending point of the target region in the current row. The continuous region formed by all pixels between the starting and ending points is determined as the target region corresponding to the current row.

[0084] Specifically, when judging the pixel values ​​after the starting point of the current row point by point, if the currently detected pixel value is less than the second threshold, the temporary end point of the row is continuously updated; when a pixel value is detected to be greater than or equal to the second threshold, if there are still pixels less than the second threshold, the detection needs to continue and the temporary end point is updated; the detection stops when a pixel value is greater than or equal to the second threshold and all subsequent pixel values ​​remain greater than or equal to the second threshold.

[0085] By performing non-target area cropping on both ends of the current row, the target area is constructed only within the effective pixel coverage area. This can shorten the single movement distance of the engraving head and effectively compress the engraving time of each row.

[0086] Optionally, after taking the pixel corresponding to the currently determined pixel value as the starting point of the target region in the current row, the method further includes:

[0087] If all pixel values ​​following the starting point in the current row are less than the second threshold, then the last pixel in the current row is taken as the endpoint of the target region in the current row.

[0088] Specifically, when judging the pixel values ​​after the starting point of the current row point by point, if all pixel values ​​after the starting point of the current row are less than the second threshold, then the last pixel of the current row (the last valid pixel) is taken as the endpoint of the target region in the current row.

[0089] By performing non-target area cropping on both ends of the current row, the target area is constructed only within the effective pixel coverage area. This can shorten the single movement distance of the engraving head and effectively compress the engraving time of each row.

[0090] In this plan, such as Figure 5 As shown, further analysis of the current row's pixel data reveals that the first valid pixel is used as the start point (startPoint) and the last valid pixel as the end point (endPoint), cropping the blank pixel areas on both sides. The target region is generated only for the content within the valid pixel range, thus shortening the carving time and movement distance for each row.

[0091] Optionally, determining the target region based on the pixel data of the target image includes:

[0092] The target regions corresponding to all rows of the target image are integrated to obtain the complete target region of the target image.

[0093] In this scheme, the target image is scanned and processed line by line to accurately locate the target region corresponding to each row of pixel data; after the target regions of all rows are identified, the target regions determined by each row are systematically integrated; through integration and optimization, a complete and coherent target region of the target image is finally generated.

[0094] By defining the target area, invalid paths during laser engraving are significantly reduced, improving overall processing efficiency; the frequent movement of the laser head in non-target areas is reduced, extending machine lifespan; and waste of equipment resources is avoided.

[0095] S460. Generate a corresponding engraving path according to the target area, and control the laser device to perform engraving operation according to the engraving path to complete the image engraving.

[0096] In this plan, such as Figure 5 As shown, GCode control commands are generated to control the laser device to perform engraving operations in order to complete image engraving.

[0097] The technical solution of this invention involves: acquiring an image to be engraved; performing grayscale conversion on the image to obtain a target image; acquiring the pixel data of the current row in the target image; determining whether the pixel data of the current row is greater than a preset first threshold; if not, determining the target area corresponding to the current row based on the comparison result between the pixel data of the current row and a preset second threshold; generating a corresponding engraving path based on the target area; and controlling the laser device to perform engraving operations based on the engraving path to complete the image engraving. By implementing this technical solution, invalid paths during laser engraving are significantly reduced, improving overall processing efficiency; reducing frequent movement of the laser head in non-target areas, extending machine lifespan; avoiding waste of equipment resources; reducing the number of generated GCode instructions to optimize transmission and storage; and this solution is easily integrated into existing image-to-GCode workflows, possessing good scalability.

If the currently judged pixel value is less than the second threshold, the temporary endpoint of the current row is continuously updated until a pixel value greater than or equal to the second threshold is detected.
