[0035] This application provides a light source switching method, apparatus, device, and computer-readable storage medium. The light source switching method is applied to a light source switching system, which includes a light source and multiple light source channels corresponding to different colors. The light source switching method includes: acquiring a target material type of a material to be processed; determining a target light source color corresponding to the material to be processed based on the target material type; activating one or more target channels in each of the light source channels based on the target light source color, and deactivating other channels in each of the light source channels except for the target channel, so that the light source switches the color of its output light to the target light source color.

[0036] Compared to existing technologies that only use monochromatic light sources, the light source switching method of this application uses light sources with multiple colors. First, the target material type corresponding to the material is obtained. Then, the target light source color to be used for the material to be processed is determined according to the target material type. Then, the target channel in each light source channel is opened according to the target light source color, and other channels except the target channel are closed, so that the color of the light output by the light source is switched to the target light source color.

[0037] Thus, based on the above-mentioned method of controlling the activation of multiple colors of light sources according to the material number, compared with the traditional method of using only a single monochromatic light source, the light source switching method of this application allows each light source channel of the light source to be activated simultaneously. That is to say, the light source can output multiple colors of light to adapt to different material types. Furthermore, the type of color of the light output by the light source can be controlled according to the type of material, and the switching of the light source can be automated.

[0044] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0045] It should be noted that the commonly used light source colors for vision are W (white), B (blue), and R (red), and the choice of visual light source color often affects the imaging effect.

[0046] In the material processing process, the selection of light source is mainly based on factors such as the color, shape, and working distance of the material provided by the customer. In existing material processing systems, only a single-color light source can often be provided. However, the types of materials that a single-color light source can be compatible with are limited, which restricts the selection of materials and reduces the efficiency of material processing.

[0047] To address the aforementioned problems, this application provides a light source switching method, apparatus, device, and storage medium. The light source switching method is applied to a light source switching system, which includes a light source comprising multiple light source channels corresponding to various colors. The light source switching method includes: acquiring a target material type of a material to be processed; determining a target light source color corresponding to the material to be processed based on the target material type; activating one or more target channels in each of the light source channels based on the target light source color, and deactivating other channels in each of the light source channels except for the target channel, thereby switching the color of the output light from the light source to the target light source color.

[0048] Compared to existing technologies that use only a single-color light source, the light source switching method of this application uses a light source with at least three colors. First, the target material type corresponding to the material is obtained. Then, the target light source color to be used for the material to be processed is determined according to the target material type. Then, the target channel in each light source channel is controlled to open according to the target light source color, and other channels except the target channel are closed, so that the final output color of the light source is switched to the target light source color.

[0049] Thus, based on the above-mentioned method of controlling the activation of light sources of at least three colors according to the material number, compared with the traditional method of using only a single monochromatic light source, the light source switching method of this application allows each light source channel of the light source to be activated simultaneously. That is to say, the light source can output multiple colors of light, adapting to different material types. Furthermore, the type of light source can be controlled according to the material type, and the switching of light sources can be automated. Therefore, the technical solution adopted in this application can improve the compatibility of light sources and improve the efficiency of material processing.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

The communication bus 1002 is used to establish communication between the processor 1001 and the memory 1005. The memory 1005 may be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0056] like Figure 1 As shown, the memory 1005, which serves as a computer storage medium, may include an operating system, a network communication module, and a light source switching program. The operating system is a program that manages and controls the hardware and software resources of the light source switching device, supporting the operation of the light source switching program and other software and / or programs. The network communication module is used to enable communication between the various components within the memory 1005, as well as communication with other hardware and software in the light source switching device.

[0058] Obtain the target material type of the material to be processed;

[0059] Determine the target light source color corresponding to the material to be processed based on the target material type;

[0060] Based on the target light source color, one or more target channels in each of the light source channels are activated, and other channels in each of the light source channels except for the target channel are closed, so that the light source switches the color of the output light to the target light source color.

[0061] Furthermore, the processor 1001 can call the light source switching program stored in the memory 1005 and also perform the following operations:

[0062] Obtain the material number of the material to be processed;

[0063] The target material type corresponding to the material number is determined according to a preset mapping relationship, wherein the mapping relationship is: one material type corresponds to one or more material numbers.

[0064] Furthermore, the processor 1001 can call the light source switching program stored in the memory 1005 and also perform the following operations:

[0065] The working distance between the material to be processed and the distance measuring instrument is obtained based on the distance measuring instrument;

[0066] The working brightness of each of the light source channels is controlled based on a preset correspondence and the working distance, wherein the working distance is positively correlated with the working brightness.

[0067] Furthermore, the processor 1001 can call the light source switching program stored in the memory 1005 and also perform the following operations:

[0068] The distance parameter between the measuring point of the measuring instrument and the measuring instrument is obtained in real time based on the measuring instrument, wherein the measuring point is on the surface of the processing table or on the surface of the material to be processed on the processing table;

[0069] If the distance parameter is greater than the preset distance threshold, it is determined that the measuring point is on the surface of the processing table, that is, there is no material to be processed in the light source switching system, and the light source is turned off;

[0070] If the distance parameter is not greater than the preset distance threshold, then the distance measuring point is determined to be on the surface of the material to be processed.

[0071] Furthermore, the processor 1001 can call the light source switching program stored in the memory 1005 and also perform the following operations:

[0075] Determine whether any of the stored color features contains a target color feature that corresponds to the target color parameter;

[0076] If the target color feature exists, the target material type corresponding to the material to be processed is determined based on the target color feature.

[0077] Furthermore, the processor 1001 can call the light source switching program stored in the memory 1005 and also perform the following operations:

[0078] If the target color feature does not exist, the target color parameter is stored as the color feature of the target material type.

[0079] Furthermore, the processor 1001 can call the light source switching program stored in the memory 1005 and also perform the following operations:

[0080] Determine whether the material to be processed exists in the image acquired in real time by the camera;

[0081] If the material to be processed is not present, the light source is turned off.

[0082] The specific implementation of the light source switching device in this application is basically the same as the embodiments of the light source switching method described below.

[0083] This application provides a light source switching method. In the first embodiment of the light source switching method of this application, please refer to... Figure 2 The light source switching system includes: a light source, the light source including multiple light source channels corresponding to various colors; the light source switching method includes:

[0084] Step S10: Obtain the target material type of the material to be processed;

[0085] Step S20: Determine the target light source color corresponding to the material to be processed based on the target material type;

[0086] In this embodiment, different material types require different colored light sources for imaging. Therefore, the system also presets the correspondence between material types and light source colors. First, the target material type of the material to be processed is obtained according to the parameters output by the technician. After determining the target material type of the material to be processed, the target light source color corresponding to the target material type is obtained from the system according to the target material type.

[0087] Step S30: Based on the target light source color, activate one or more target channels in each of the light source channels, and close other channels in each of the light source channels except for the target channel, so that the light source switches the color of the output light to the target light source color.

[0088] In this embodiment, each color in the multi-color light source corresponds to a light source channel. After obtaining the target light source color corresponding to the material to be processed, one or more target channels in each light source channel are turned on based on the target light source color, while other channels are turned off, so that the color presented by the light source corresponds to the target light source color.

[0089] For example, in one embodiment, a light source containing white, red, and blue light source channels is used to process materials with a silver base color. In this case, the light source channel corresponding to blue is turned on, and the light source channels corresponding to white and red are turned off, so that the color of the light output by the light source is switched to blue.

[0090] Furthermore, in a feasible embodiment, step S10 above, the step of obtaining the target material type of the material to be processed, includes:

[0091] Step S101: Obtain the material number of the material to be processed;

[0092] Step S102: Determine the target material type corresponding to the material number according to the preset mapping relationship, wherein the mapping relationship is: one material type corresponds to one or more material numbers.

[0093] In this embodiment, when a batch of materials needs to be processed, since vision cannot automatically identify the type of materials, technicians need to number the materials and input the numbers into the light source switching system. The system stores the mapping relationship between material numbers and material types. One material type can correspond to multiple material numbers. After the system obtains the material number, it parses the material number to obtain the target material type of the material to be processed.

[0094] Specifically, staff first name the different materials at the customer's site sequentially and use the shape int as the internal drawing number of the system software. Then, when processing the materials, the corresponding number of the material is input into the software. After the system obtains the material number, it parses the number to obtain the target material type of the material. Then, based on the target material type of the material, it determines the corresponding target color type. The system vision is connected to the light source channels corresponding to each color via serial communication. After obtaining the target color type, the system controls the channel that needs to be lit to be turned on based on serial communication, and other channels are set to zero and turned off. For example, when processing materials with a green background and white markers, the red channel can be lit. Or, when processing materials with a silver background, the blue channel can be lit.

[0095] Although the commonly used light source colors are white, red, and blue, a light source can include more than three light source channels, and these channels can be combined and lit to produce a variety of different colors of light to suit various types of materials.

[0096] Compared to existing technologies that use only a single-color light source, the light source switching method of this application uses a light source with at least three colors. First, the target material type corresponding to the material is obtained. Then, the target light source color to be used for the material to be processed is determined according to the target material type. Then, the target channel in each light source channel is controlled to open according to the target light source color, and other channels except the target channel are closed, so that the final output color of the light source is switched to the target light source color.

[0097] Thus, based on the above-mentioned method of controlling the activation of light sources of at least three colors according to the material number, compared with the traditional method of using only a single monochromatic light source, the light source switching method of this application allows each light source channel of the light source to be activated simultaneously. That is to say, the light source can output multiple colors of light, adapting to different material types. Furthermore, the type of light source can be controlled according to the material type, and the switching of light sources can be automated. Therefore, the technical solution adopted in this application can improve the compatibility of light sources and improve the efficiency of material processing.

[0098] Furthermore, based on the first embodiment of the light source switching method of this application described above, a second embodiment of the light source switching method of this application is proposed.

[0099] In a second embodiment of the light source switching method of this application, the light source switching system further includes: a rangefinder; after step S30 above, where the light source switches the color of its output light to the color of the target light source, the light source switching method of this application further includes:

[0100] Step A10: Obtain the working distance between the material to be processed and the rangefinder based on the rangefinder;

[0101] In this embodiment, the light source switching system also includes a rangefinder, which can be positioned directly above the processing table supporting the material to avoid affecting the accuracy of the rangefinder due to the material's placement. During material processing, the rangefinder measures the working distance between the material and the rangefinder.

[0102] Step A20: Control the working brightness of each of the light source channels based on a preset correspondence and the working distance, wherein the correspondence is that the working distance and the working brightness are positively correlated.

[0103] In this embodiment, the distance between the light source and the material to be processed also affects the parameters of the light source. Therefore, the working brightness of each light source channel in the light source is adjusted based on the working distance measured by the rangefinder. The farther the working distance, the brighter the working brightness of the target channel in the working state in each channel, so as to ensure the stability of imaging.

[0104] Furthermore, in a feasible embodiment, the light source switching system further includes: a processing table, the processing table being located directly below the rangefinder; after step A20 above, the step of controlling the working brightness of each of the light source channels based on a preset correspondence and the working distance, the light source switching method of this application further includes:

[0105] Step B10: Based on the distance measuring instrument, the distance parameter between the measuring point of the distance measuring instrument and the distance measuring instrument is obtained in real time, wherein the measuring point is on the surface of the processing table or on the surface of the material to be processed on the processing table.

[0106] Step B20: If the distance parameter is greater than the preset distance threshold, it is determined that the measuring point is on the surface of the processing table, that is, there is no material to be processed in the light source switching system, and the light source is turned off.

[0107] Step B30: If the distance parameter is not greater than a preset distance threshold, then it is determined that the measuring point is on the surface of the material to be processed.

[0108] In this embodiment, during the processing, the rangefinder acquires the distance parameters between the rangefinder and the measuring point in real time. The rangefinder can be an infrared rangefinder, emitting infrared light downwards from directly above the processing table. Those skilled in the art will understand that when there is no material on the processing table, the infrared light from the rangefinder illuminates the table surface, meaning the measuring point is the table surface. When there is material on the processing table, the material blocks the table, and the infrared light from the rangefinder illuminates the surface of the material on the table surface, meaning the measuring point is the surface of the material. When it is detected that there is material to be processed on the processing table, the light source switching system operates normally because... The positions of the workbench and the distance measuring instrument are fixed, so the distance measured between them is also fixed, although there may be slight fluctuations within a small range. However, the material has a certain thickness, meaning that when the material is placed on the workbench, the distance from the material surface to the distance measuring instrument is always smaller than the distance from the workbench surface to the distance measuring instrument. Therefore, a distance threshold can be set based on the distance between the workbench and the distance measuring instrument. Then, the relationship between the real-time measured distance parameter and the distance threshold can be used to determine whether there is material on the workbench. If the distance parameter is greater than the distance threshold, it means that there is no material on the workbench, and the light source can be turned off to save power.

[0109] Specifically, when processing materials, the system determines which channels of the light source are turned on based on the material's number. Then, it controls the brightness of each channel of the light source based on the working distance of the material to be processed measured by the rangefinder. The system also acquires the distance parameters measured by the rangefinder in real time. If the distance parameters are found to be greater than the distance threshold, it means that the processing work is over and the material is no longer on the processing table. At this time, the light source is turned off to save power.

[0110] Thus, based on the above-mentioned method of controlling the brightness of at least three colors of light source according to the working distance measured by the rangefinder, compared with the traditional method of using only a single monochromatic light source, the light source switching method of this application can adaptively adjust the brightness of the light source according to the working distance, improve the imaging effect, and can turn off the light source in time after the material is removed from the processing table to save energy. Therefore, the technical solution adopted in this application can improve the compatibility of the light source and improve the working efficiency of material processing.

[0111] Furthermore, based on the first and second embodiments of the light source switching method of this application described above, a third embodiment of the light source switching method of this application is proposed.

[0112] In a third embodiment of the light source switching method of this application, the light source switching system further includes: a camera; the light source switching system stores multiple material types, each of which includes multiple color features; the light source switching method of this application further includes:

[0113] Step C10: Control the camera to acquire a target image of the material to be processed;

[0114] Step C20: Identify the colors of the materials to be processed in the target image;

[0115] In this embodiment, a camera is assumed above the processing table. The camera is used to acquire the target image of the material to be processed on the processing table in real time. When the presence of the material to be processed on the processing table is detected, the target image of the material to be processed is acquired. The material in the target image can be distinguished from the background by existing image recognition technology, and then the various colors of the material in the target image and the outlines corresponding to each color are identified.

[0116] Step C30: Calculate the area ratio of each material color in the material to be processed, and use each area ratio as the target color parameter of the material to be processed;

[0117] In this embodiment, the area occupied by each color can be calculated based on the outline corresponding to each color, and then the area ratio of each color in the color of the material can be calculated based on the area occupied by each color, and the calculated ratio is used as the color parameter of the material to be processed.

[0118] Step C40: Determine whether any of the stored color features contains a target color feature corresponding to the target color parameter;

[0119] Step C50: If the target color feature exists, determine the target material type corresponding to the material to be processed based on the target color feature.

[0120] In this embodiment, the system stores multiple material types, each of which includes multiple color features. After obtaining the target color parameter of the material to be processed, the system searches for the existence of the target color parameter in the color features of each material type stored in the system. If the target color parameter exists, the target material type of the material to be processed can be determined to be the material type corresponding to the target color parameter. The color of the light source can then be determined and the light source controlled based on the material type.

[0121] Furthermore, in a feasible embodiment, after step C40 above, which determines whether any of the stored color features contains a target color feature corresponding to the target color parameter, the method further includes:

[0122] Step C60: If the target color feature does not exist, then the target color parameter is stored as the color feature of the target material type.

[0123] In this embodiment, the system searches for the existence of the target color parameter in the color features of each material type stored in the system. If the target color parameter does not exist, the target material type of the material to be processed is determined according to the number of the material to be processed, based on the method in Embodiment 1 above. Then, the target color parameter is stored as the color feature of the target material type. If there are materials with the same features in subsequent processing, the type of material can be directly determined.

[0124] Furthermore, in one feasible embodiment, the light source switching method of this application further includes:

[0125] Step D10: Determine whether the material to be processed exists in the image acquired in real time by the camera;

[0126] Step D20: If the material to be processed does not exist, then turn off the light source.

[0127] In this embodiment, during the processing, the presence of materials on the processing table can be determined in real time by the images captured by the camera. If there are no materials on the processing table, the light source is turned off to save energy.

[0128] Specifically, the system is equipped with a camera that captures images of the processing table in real time. When material is detected on the processing table, the system acquires a target image of the material to be processed, identifies the color of the material in the image, calculates the area and proportion of each color, and uses the proportion as the target color parameter of the material to be processed. For example, if the material is blue, it is recorded as B100%. If the material has a green background with white dots, and the calculated proportion of green area is 80%, then the color parameter of the material is G80%_W20%. The system searches for the existence of the target color parameter in the color features. If it exists, the light source can be controlled directly according to the material type corresponding to the color feature. If it does not exist, the material type is determined according to the material number, and the target color parameter is added to the color feature of that material type. After the camera detects that there is no material in the image, it turns off the light source to save power.

[0129] Thus, based on the above-mentioned method of controlling the activation of light sources of at least three colors according to the material number, compared with the traditional method of using only a single monochromatic light source, the light source switching method of this application identifies the color parameters of the material by a camera, then compares them with the stored color features to determine the type of material, and controls the light source based on the type of material, thereby realizing the automation of light source switching. Therefore, the technical solution adopted in this application can improve the compatibility of the light source and improve the work efficiency of material processing.
