[0047] The following combination Figure 1-Figure 5 This application is described in further detail.
[0048] An embodiment of the present application discloses a thermal map drawing method, which is applied to a thermal map drawing system. The method can be used to draw a rectangular defect thermal map, so that quality inspectors can more intuitively view the distribution locations of defects and the number of defect stackings in the same area. Quality inspectors can focus on checking areas with a large number of defect stackings to ensure the quality of product production.
[0049] In the process of product production, defect detection is an essential step. Defect detection can be used to troubleshoot and solve product defects, thereby improving the yield of the product. In the process of defect detection, users can usually use a rectangular box to mark the defective part with a rectangular detection box to obtain a rectangular defect. For the same batch of materials, the rectangular defects detected on each material are displayed in the form of a heat map for the convenience of quality inspectors to view. When drawing a heat map, the defects of the same batch of materials are displayed on a canvas, and the distribution of defects in different areas is displayed by the depth of color. For example, when the color of an area is dark, it means that there may be multiple materials with defects in the same area. Quality inspectors need to focus on the location of the area. If the color of an area is light, it means that only individual materials have defects at that location. It may be an accidental situation and can be set as a non-key area for investigation.
[0050] However, some existing third-party plug-ins generally use point drawing to draw heat maps. Point drawing heat maps display data sets in the form of scattered points. For the drawing of rectangular defects, the final displayed data set is less intuitive, which may cause quality inspectors to spend more time parsing and analyzing data, thereby affecting the efficiency of defect detection. In order to help improve the efficiency of defect detection, the present application provides a heat map drawing method.
[0051] Reference Figure 1 , the method comprises the following steps:
[0052] S10, obtaining the coordinates of the rectangular defect and the maximum stacking times of the rectangular defect, and drawing a valued color bar according to the maximum stacking times of the rectangular defect.
[0053] Specifically, the rectangular defect heat map is drawn on the front end through canvas. Canvas is a tag in HTML5 that provides a blank canvas on which graphics can be drawn through JavaScript. The heat map drawing system can directly obtain the coordinates of the rectangular defects and the maximum number of stacking of rectangular defects through the back end; the rectangular defect can also be understood as a rectangular box marked according to the size and position of the defect after the defect is detected. The maximum number of defect stacking can be understood as the maximum number of times a defect occurs in the same area. For example, refer to Figure 2 , the maximum stacking number of rectangular defects is 2. Draw a valued color bar according to the obtained maximum stacking number; wherein the valued color bar is a color bar corresponding to the preset color value and the stacking number of rectangular defects, and the height of the valued color bar can be determined according to the maximum stacking number of rectangular defects and a preset constant.
[0054] Specifically, the method for determining the height of the assigned color bar includes: first, judging whether the maximum stacking number of rectangular defects is less than the preset number; if the maximum stacking number of rectangular defects is less than the preset number, the height of the assigned color bar is the maximum stacking number of rectangular defects multiplied by the preset constant; if the maximum stacking number of rectangular defects is not less than the preset number, the maximum stacking number of rectangular defects is set as the height of the assigned color bar. For example, assuming that the preset constant is 10 and the preset number of stacking is set to 20, first, judge whether the maximum number of stacking obtained is less than 20. If the maximum number of stacking is less than 20, the height of the assigned color bar is the maximum number of stacking times multiplied by 10. If the maximum number of stacking is greater than or equal to 20, the maximum number of stacking is directly set as the height of the assigned color bar; for example, assuming that the maximum number of stacking is 5, 5 is less than 20, the height of the assigned color bar is set to 5*10=50, assuming that the maximum number of stacking is 80, 80 is greater than 20, the height of the assigned color bar is directly set to 80, and the preset constant defaults to 1. It should be noted that the preset constant and the preset value of the number of stacking in the embodiment of the present application can be set according to actual needs, and there is no restriction here.
[0055] S20, calculating the transparency of each pixel in the canvas according to the coordinates of the rectangular defect and the maximum number of stacking times of the rectangular defects.
[0056] Specifically, the transparency of each pixel in the canvas is calculated according to the position of the rectangular defect and the number of times the rectangular defects are stacked. Since different transparencies correspond to different stacking times, and different stacking times correspond to different color values, the transparency of each pixel is calculated to facilitate the determination of the color value corresponding to each pixel.
[0057] The transparency calculation method of each pixel may include: first, calculating the transparency of a single layer of rectangular defects according to the maximum number of stacking times of rectangular defects. The transparency calculation method of a single layer of rectangular defects is to divide 1 by the maximum number of stacking times. For example, if the maximum number of stacking times is 20, the transparency of each layer of rectangular defects is 1 / 20, which is 0.05. After calculating the transparency of a single layer of rectangular defects, all rectangular defects can be drawn on the canvas with different degrees of transparency according to the coordinates of the defects to generate a transparency display diagram of rectangular defects; the coordinates of the rectangular defects can determine the specific position of the rectangular defects on the canvas, and the rectangular defects of all materials are drawn on a canvas. The transparency of different areas can be obtained by superimposing single layers of transparency. Assuming that the transparency of a single layer of defects is 0.05, in the defect transparency display diagram, the transparency value of the rectangular defects at the position where the number of stacking times is 20 is 1, the transparency of the rectangular defects stacked once is 0.05, and the transparency of the position without rectangular defects is 0. Afterwards, the number of stacking times for each pixel can be obtained according to the defect transparency display diagram. After obtaining the number of stacking times for each pixel, the transparency of each pixel in the canvas is calculated. The range of pixel transparency is 0 to 255, where 0 represents full transparency and 255 represents full opacity.
[0058] S30, determining a color determination value for each pixel according to the transparency of each pixel and the maximum number of stacking times of rectangular defects, and searching for a corresponding color in the assigned color bar according to the color determination value for each pixel.
[0059] Specifically, the assigned color bar pre-sets the color value corresponding to each stacking number. After calculating the transparency of each pixel, the color value of each pixel can be determined based on the pixel transparency and the maximum stacking number, and then the corresponding color in the assigned color bar is searched based on the color value.
[0060] The color value of each pixel can be determined as follows:
[0061] J = imgeData[i] / (255 / maximum stacking times)*4*indexValue;
[0062] Among them, J represents the color value of each pixel, imgeData[i] represents the transparency of each pixel in the canvas, and indexValue represents a preset constant.
[0063] S40, coloring the color corresponding to each pixel found to the canvas, and generating a final defect heat map.
[0064] Specifically, after finding the color corresponding to each pixel, the color of each pixel is colored on the canvas, and a defect heat map is generated through different colors and color depths. The generated defect heat map can show the distribution of defects for quality inspectors to view and analyze.
[0065] In the present application, a heat map showing the defect distribution can be drawn on the canvas through the rectangular defect coordinates and the maximum stacking number of rectangular defects, so that quality inspectors can see the distribution of defects more intuitively, so that quality inspectors can focus on inspecting a certain area according to the defect stacking situation, thereby improving the efficiency of defect detection.
[0066] In one embodiment, considering that it is inconvenient to observe and analyze the details of a certain area in a complete defect heat map, the following steps may be performed before determining the color determination value of each pixel according to the transparency of each pixel and the maximum number of stacking times of rectangular defects:
[0067] First, draw the slider color bar according to the maximum number of stacking times of rectangular defects. Set the slider color bar as follows Figure 3 As shown, the set slider color can be displayed on the front page for the user to select the area to be viewed. After that, the maximum and minimum values of the slider color bar are set. The maximum value of the slider color bar is not greater than the maximum stacking times of rectangular defects. The setting method is that the user sets it according to the needs. Specifically, the user selects the area to be viewed to set the maximum and minimum values of the stacking times. The user transmits the information of the set maximum and minimum values to the system, and the system sets the maximum and minimum values of the slider according to the received range information; for example, refer to Figure 3 (a) The user did not set the range of the maximum and minimum values. When the maximum number of stacking times of a batch of materials is 81, the maximum value of the slider is set to 81, the minimum value of the slider is set to 0, and the slider color bar is displayed on the front end. Figure 3 (b), users can choose to set the number of stacking times they need to focus on. When the user wants to view the defect distribution area with a stacking number between 85 and 197, the maximum value of the slider color can be set to 197 and the minimum value of the slider color bar can be set to 85. By setting the slider color bar, users can view the area they need to analyze, which increases flexibility. After determining the maximum and minimum values of the slider color bar, calculate the color value range of each pixel based on the maximum and minimum values of the slider color bar.
[0068] Afterwards, determining the color determination value of each pixel according to the transparency of each pixel and the maximum number of stacking times of rectangular defects may be specifically performed as follows:
[0069] The color value of each pixel is calculated according to the transparency of each pixel and the maximum stacking number of rectangular defects, and the color calculation value of each pixel is generated; whether the color calculation value of each pixel is within the color value range is judged, and the color determination values of several pixels are determined according to the judgment result.
[0070] The method of determining the color determination values of a plurality of pixels according to the judgment result may be specifically performed as follows:
[0071] If the color calculation value of the pixel is not within the color value range, and the color calculation value is greater than the upper limit of the color value range, the upper limit of the color value range is set as the color determination value of the pixel; if the color calculation value of the pixel is not within the color value range, and the color calculation value is less than the lower limit of the color value range, the color determination value of the pixel is set to 0; if the color calculation value of the pixel is within the color value range, the color calculation value is set as the color determination value of the pixel. For example, refer to Figure 3 (b) The user determines the maximum value of the slider color bar as 197 and the minimum value as 85 according to the user's needs. First, the color value range is calculated according to the user's needs. The calculated color maximum value corresponding to 197 is assumed to be J max , the minimum color value corresponding to 85 is assumed to be J min , calculate the color value J of each pixel according to the transparency and the maximum number of stacking times. If the calculated J is in [J min , J max ], the calculated color value is directly set as the color value of the pixel. If the calculated J is greater than J max , then J max Set to the color value of the pixel. If the calculated J is less than J min , then the color value of the pixel can be directly set to 0.
[0072] In the present application, considering that the global reality defect heat map is difficult to view and analyze the details of the defect distribution in different locations and regions, therefore, by setting the slider tone and dynamically drawing the heat map, the user can more intuitively view the area location required by the user, which is more helpful for quality inspectors to analyze the defect distribution and subsequently conduct targeted investigation of the causes of defects.
[0073] In one embodiment, considering that it is difficult for the naked eye to directly obtain the number of stacking times corresponding to a color when the colors are similar, after coloring the color corresponding to each pixel found to the canvas and generating the final defect heat map, the following steps may be performed:
[0074] In response to the instruction to obtain the number of stacks, the number of stacks at the position to be obtained is determined according to the color value of the position to be obtained and the assigned color bar, and the number of stacks at the position to be obtained is displayed. In actual applications, in the canvas interface, the mouse moves to the position where the number of stacks needs to be displayed in the canvas, and the system receives an instruction to obtain the number of stacks, finds the corresponding number of stacks by determining the color value of the current position, and displays the number of stacks in the rectangular box following the mouse. If the number of stacks is 0, it is not displayed.
[0075] In the present application scheme, it is considered that when the colors are similar, it is difficult for the human eye to distinguish the colors, and the stacking number corresponding to the color is directly obtained by the color. Therefore, the stacking number display setting is used to allow the user to view the stacking number, so that the key points can be checked according to the stacking number to improve the efficiency of defect detection.
