[0052] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0053] Figure 1 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[0054] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] like Figure 1As shown, a processing control method for a laser engraving machine includes:

[0056] Step S1: Obtain the user's engraving scene requirements and corresponding laser engraving machine information, and determine the corresponding engraving types according to the obtained engraving scene requirements and laser engraving machine information;

[0057] The engraving type refers to the various types of engraving that the laser engraving machine can perform to meet the user's engraving scene needs, such as three-dimensional material engraving, metal engraving, wood engraving, etc.

[0058] After the user purchases a laser engraving machine, he or she can input the corresponding engraving scene requirements through the input function of the laser engraving machine according to his or her own business requirements. The engraving scene requirements include the background environment that the user wants to operate, such as ancient building scenic spots, seaside scenic spots, snack streets and other backgrounds, including the corresponding scene name, location and other related information, so as to facilitate the subsequent acquisition of more detailed data in the scene through maps, online travel and other methods; determine the type of engraving that the engraving machine can achieve based on the laser engraving machine information, and then match it according to the engraving scene requirements to obtain the corresponding engraving type.

[0059] In one embodiment, the engraving type may be set in the following manner; the method includes:

[0060] The laser engraving machine that needs to be processed and controlled is marked as a candidate engraving machine, which is generally a laser engraving machine produced by the manufacturer. However, when the manufacturer modifies the laser engraving machine of other brands to realize the control system as in the present invention, it can also be used as a candidate engraving machine. The specific needs are set according to the actual needs of the manufacturer, as long as the setting requirements of the candidate engraving machine can be met, such as the corresponding control modification can be realized;

[0061] According to the possible user engraving scene requirements, the corresponding demand list is set, and the analysis and setting are performed manually. At the same time, the business scope of the manufacturer needs to be considered, because some engraving scene requirements are not within the business scope of the manufacturer, so it is more convenient and efficient to set them manually; mark the engraving scene requirements of each user recorded in the demand list as statistical requirements;

[0062] Set up corresponding types of engraving to be selected for statistical needs, that is, analyze which types of engraving can meet the engraving needs and mark them as types of engraving to be selected; for example, for the common customer photo engraving needs in scenic spots, flat engraving of different materials or three-dimensional engraving of different materials can be used, and the types of engraving to be continued corresponding to the statistical needs can be summarized; set the engraving functions corresponding to each type of engraving to be selected, that is, which engraving functions are needed to achieve the engraving of this type of engraving, and which optional engraving functions are available, so as to form the functional range of the type of engraving to be selected; use the existing laser engraving historical data to make corresponding settings; add the obtained types of engraving to be selected and the corresponding functional range to the demand list;

[0063] Identify the obtained engraving scene requirements and laser engraving machine information, input the obtained engraving scene requirements into the requirements list for matching, and obtain corresponding engraving types to be selected and corresponding functional ranges;

[0064] The obtained laser engraving machine information is identified, and each engraving function corresponding to the laser engraving machine is obtained. The engraving functions obtained and the function ranges corresponding to each selected engraving type are screened to obtain the engraving function corresponding to the laser engraving machine.

[0065] Step S2: setting a corresponding background pre-model according to the obtained engraving scene requirements;

[0066] The method for establishing the background pre-model includes:

[0067] Set each target background according to the engraving scene requirements; establish corresponding background pre-models according to each target background, and the background pre-model is a three-dimensional model. After determining each target background, use the existing modeling technology to generate the corresponding three-dimensional model of the target background. The platform, manufacturer, etc. set the model establishment technology, which is generally built-in in the laser engraving machine. It can also be established by the user end, network platform, etc., and the target background is sent to the corresponding user end, network platform, etc., and then the corresponding background pre-model is established.

[0068] The target background is the carving background that the user may use later, such as pavilions, gatehouses, ponds and other related backgrounds in scenic spots. Because they appear frequently, they are used as modeling materials in order to save subsequent modeling time.

[0069] In one embodiment, the user may directly upload the target background that he or she identifies.

[0070] In another embodiment, the method of the above embodiment is not smart enough, and the problem of incompleteness will occur when users upload by themselves, which requires a long accumulation period and requires users to continuously find missing target backgrounds according to customer business, which is inefficient; therefore, the following method is proposed in this embodiment for intelligent screening, and the method is as follows:

[0071] Retrieve real-time carving background data according to the carving scene requirements, such as docking with the corresponding online tourism system to obtain the photos of each scene; you can also retrieve the photos of relevant tourists and others related to the carving scene requirements through the Internet;

[0072] Identify various candidate backgrounds in the carving background data, obtain the occurrence times of each candidate background and the quantity proportion of the overall quantity it occupies, and mark the obtained occurrence times and quantity proportion as NC and x respectively;

[0073] Estimate the optimization duration of the candidate background, that is, estimate the establishment duration corresponding to establishing a background pre-model with this candidate background as the target background. Since the accuracy requirement is not high, the establishment duration can be directly used as the optimization duration to shorten the subsequent establishment duration; or other existing evaluation techniques can be used to evaluate a more accurate time saving; mark the obtained optimization duration as ST;

[0074] Calculate the corresponding target evaluation value according to the target evaluation formula PGL = b1×NC×G(x)+b2×ST, where PGL is the target evaluation value; b1 and b2 are both proportionality coefficients, and the value range is 0 < b1 ≤ 1, 0 < b2 ≤ 1; G(x) is a proportion correction model, X1 is the threshold;

[0075] Mark the candidate background with the target evaluation value greater than the threshold X2 as the recommended background, send the recommended background to the user for selection, and mark the recommended background selected by the user as the target background.

[0076] In one embodiment, as the user uses the laser engraver for business, there will be a background pre-model without a corresponding engraving photo provided by the customer. At this time, it is necessary to determine whether to use it as the target background, and the determination method of the target background after operation is different from the determination method before operation. The method is as follows:

[0077] Mark the background corresponding to the corresponding engraving photo as the background to be added;

[0078] Obtain the recording times of each background to be added, which refers to the number of times uploaded by the user after operation; then the target evaluation formula is updated to PGL = b1×(NC + δ×N)×G(x)+b2×ST, where N is the recording times, δ is an adjustment coefficient, generally taking 10, and is adjusted by the user according to his own evaluation; mark the candidate background with the target evaluation value greater than the threshold X2 as the recommended background, send the recommended background to the user for selection, and mark the recommended background selected by the user as the target background.

[0079] In another embodiment, the method for establishing the background pre-model includes:

[0080] Identify the overall scene data corresponding to the carving scene requirements, such as the overall scope of the scenic spot, related image data, etc., and establish a corresponding overall scene model based on the obtained overall scene data, that is, establish a panoramic three-dimensional model of the scenic spot;

[0081] Associating the overall scene model with a corresponding position recognition model, the position recognition model is established based on the prior art and is used to recognize the corresponding area range in the overall scene model according to the photo parameters, that is, to perform scene matching according to the photo background, determine the area range corresponding to the corresponding background, and output the area model corresponding to the corresponding area range;

[0082] The overall scene model and location recognition model are integrated into the background pre-model.

[0083] The working methods of the background pre-model include:

[0084] Obtain background data for identifying customer photos, mark it as customer background data, input the obtained customer background data into the location recognition model, determine the corresponding regional model in the overall scene model, and output the obtained regional model as the target background model.

[0085] Step S3: Obtain the customer's photo, evaluate each engraving task, determine whether it meets the engraving requirements, mark the engraving task that meets the engraving requirements as the target task, otherwise it will not be regarded as an engraving task, and display the evaluation result that cannot be engraved to the corresponding customer;

[0086] The methods used to evaluate each engraving task include:

[0087] Estimate the revenue value of laser engraving corresponding to the engraving task, conduct revenue evaluation according to the engraving method selected by the customer, obtain the corresponding estimated profit, mark the corresponding profit as the revenue value, and mark the obtained revenue value as SY;

[0088] Determine whether the corresponding target background model can be matched based on the customer's photo;

[0089] When it is determined that the target background model cannot be matched, the time corresponding to generating the laser engraving task model based on the customer's photo and the corresponding laser processing time are estimated, and the task time is calculated by adding the obtained model generation time to the laser processing time;

[0090] When it is determined that the target background model can be matched, the target background model is adjusted according to the customer's photo to form a laser engraving task model, the model generation time corresponding to the laser engraving task model is estimated, the corresponding laser processing time is obtained, and the task time is calculated by adding the obtained model generation time to the laser processing time;

[0091] The obtained task time is marked as SP; according to the task evaluation formula Calculate the corresponding task evaluation value, where WPL is the task evaluation value; λ1 and λ2 are the corresponding floating coefficients, with a value range of 0≤λ1≤1, 0<λ2≤1, which are adjusted by the user and are used for the user to make preferential adjustments during the peak period of the task and select high-yield engraving tasks. For example, different time periods correspond to different floating coefficients, that is, the floating coefficient can change with time. If the user does not make adjustments, the default is λ1=0, λ2=1; then it is determined that the engraving task with a task evaluation value greater than the threshold X3 meets the engraving requirements; otherwise, it does not meet the engraving requirements.

[0092] Adjust the target background model according to the customer photo, identify the differences between the customer photo and the target background model, and make corresponding parameter adjustments, such as height, number of people, lighting, angle and other parameters. Adjust the simulation according to the corresponding parameters to form a laser engraving task model.

[0093] Step S4: Generate a laser engraving task model corresponding to the target task, and display the task time and laser engraving task model corresponding to the target task to users and customers. After the user and customer determine the target task, laser engraving is performed according to the laser engraving task model to obtain the corresponding engraving entity model.

[0094] In one embodiment, the laser engraving task model can be rendered in color based on the customer's photo to give it three-dimensional color, making it easier for the user to engrave and paint the solid model while increasing the user's income.

[0095] By analyzing and setting up each type of engraving, users and customers can quickly determine the types of laser engraving that can be performed, and customers can be assisted to quickly select the corresponding type of engraving, thereby improving engraving efficiency. By setting up the corresponding background pre-model according to the obtained engraving scene requirements, engraving efficiency can be improved, engraving time can be reduced, and users can avoid waiting for a long time, thereby achieving an optimized control method. Each engraving task can be evaluated, and the user's engraving task can be dynamically adjusted to maximize the user's benefits. This solves the current problem of customers' demand for timely engraving in scenes such as scenic spots.

[0096] A processing control system for a laser engraving machine, comprising a model module, a task module and an engraving module;

[0097] The model module is used to obtain the user's engraving scene requirements and the corresponding laser engraving machine information, determine the corresponding engraving types according to the obtained engraving scene requirements and the laser engraving machine information; and set the corresponding background pre-model according to the obtained engraving scene requirements.

[0098] The task module is used to analyze the engraving tasks, obtain customer photos, evaluate each engraving task, determine whether it meets the engraving requirements, mark the engraving tasks that meet the engraving requirements as target tasks, and otherwise display the evaluation results that cannot be engraved to the corresponding customers.

[0099] The engraving module is used to perform laser engraving, generate a laser engraving task model corresponding to the target task, and perform color rendering on the generated laser engraving task model, so as to display the task time and the laser engraving task model corresponding to the target task to users and customers. After the user and customer determine the target task, laser engraving is performed according to the laser engraving task model to obtain the corresponding engraving model.
