In this embodiment, a distance measuring method based on a virtual measurement scale is provided, which may be used for the client, and fig. 2 is a flowchart of a distance measuring method based on a virtual measurement scale according to an embodiment of the present invention, as shown in fig. 2, where the flowchart includes the following steps:

step S201, obtaining pixel coordinates of the first to-be-measured point and the second to-be-measured point.

In this embodiment, the first to-be-measured point and the second to-be-measured point are two points on the same component pattern or two points on two component patterns. And the pixel coordinates of the first to-be-measured point and the second to-be-measured point are acquired, so that the distance between two points on the same component graph or two points on different component graphs can be measured based on the first to-be-measured point and the second to-be-measured point.

In an alternative embodiment, within the target area, such as within a canvas; the first to-be-measured point and the second point measurement belong to the same two points on the component graph, such as two points on the edge of the contour, two points in the contour, or two points on the contour and in the contour. At this time, by acquiring two points on the edge of the outline, for example, acquiring points to be measured on the left and right sides of the outline of the rectangular component pattern along the horizontal direction, the length measurement of the outline of the rectangular component pattern can be realized, and the positions of other components in the outline can be confirmed. It will be appreciated that in other embodiments, the directions of the two points to be measured may be vertical directions or directions having an included angle with the horizontal direction, which is not limited herein.

In an alternative embodiment, within the target area, such as within a canvas; the first to-be-measured point and the second point measurement belong to two points which are identical to the two component patterns, for example, in the horizontal direction, one to-be-measured point can be selected on the leftmost or rightmost outline of the first component pattern, and the other to-be-measured point can be selected on the leftmost or rightmost outline of the second component pattern; or selecting a to-be-measured point from the outline of the first component pattern, and selecting another to-be-measured point from the leftmost or rightmost outline of the second component pattern; or selecting a to-be-measured point on the leftmost or rightmost outline of the first component graph, and selecting another to-be-measured point in the outline of the second component graph; and a to-be-measured point can be selected from the outline of the first component pattern, and another to-be-measured point can be selected from the outline of the second component pattern, so that the measurement of the distance between two points is realized, and the measurement of the distance between two component patterns and the determination of the distance between related components in the two component patterns are realized. The measurement of the distance between any two points on the two component graphs and the determination of the distance between related components can be realized. For example, when a to-be-measured point is selected on the leftmost or rightmost outline of the first component pattern and another to-be-measured point is selected on the leftmost or rightmost outline of the second component pattern along the horizontal direction, at least the measurement of the first component pattern length, the second component pattern length, and the distance between the first component pattern and the second component pattern may be realized.

Optionally, the pixel coordinates of the first to-be-measured point, the middle pixel coordinates and the pixel coordinates of the second to-be-measured point of the display system longitudinal and transverse position indicator in the target area in the selected operation can be obtained, so that necessary conditions are provided for the creation of a virtual measurement scale capable of measuring the positions of the key points.

In an alternative embodiment, first, pointer position information of a display system crossbar position indicator is detected, when the pointer of the display system crossbar position indicator is in a target area, an operation state of the pointer of the display system crossbar position indicator is obtained, and when the pointer of the display system crossbar position indicator is in a selected operation, pixel coordinates, middle pixel coordinates of a first to-be-measured point and pixel coordinates of a second to-be-measured point of the display system crossbar position indicator in the selected operation in the target area are obtained. The middle pixel coordinates are pixel coordinates of key points existing between the pixel coordinates of the first to-be-measured point and the pixel coordinates of the second to-be-measured point, and the number of the key points is greater than or equal to zero.

Taking electronic design automation of quantum chip design as an example, when a distance between two bonding pads (such as a first bonding pad and a second bonding pad) along a horizontal direction needs to be measured, a point can be selected from edges of one side, which are close to each other, of the first bonding pad and the second bonding pad. If the longitudinal and transverse position indicators of the display system are arranged in the left-to-right sequence, a point is selected on the right side edge of the first bonding pad to start the selection operation, and the selection operation is ended after a point is selected on the left side edge of the second bonding pad along the horizontal direction. Then, the pixel coordinates of the first to-be-measured point (selected operation start position) and the pixel coordinates of the second to-be-measured point (selected operation end position) in the selected operation are acquired. Similarly, when it is desired to measure the distance between two pads (e.g., the third pad and the fourth pad) in the vertical direction, a point may be selected at the edge of the third pad and the fourth pad on the side where they are close to each other. The selection operation is started by selecting a point on the upper side edge of the third bonding pad in the order from bottom to top through the display system vertical and horizontal position indicator, and then the selection operation is ended after selecting a point on the lower side edge of the second bonding pad in the vertical direction. Then, the pixel coordinates of the first to-be-measured point (selected operation start position) and the pixel coordinates of the second to-be-measured point (selected operation end position) in the selected operation are acquired.

Alternatively, when the length of an edge of a component along the horizontal direction and the positions of several key points (such as notches, trunking, welding spots) on the edge need to be measured, one point can be selected from the edges on the left and right sides of the component. If the longitudinal and transverse position indicators of the display system are arranged in the left-to-right sequence, firstly, selecting a point at the left side edge of the component to start the selection operation, then, carrying out the selection operation again at the key point along the horizontal direction, and finally, finishing the selection operation after selecting a point at the right side edge along the horizontal direction. Then, the pixel coordinates of the first to-be-measured point (selected operation start position), the intermediate pixel coordinates at the key point, and the pixel coordinates of the second to-be-measured point (selected operation end position) in the selected operation are acquired. Similarly, when the length of an edge of a component along the vertical direction and the positions of several key points (such as notches, trunking, welding spots) on the edge need to be measured, one point can be selected from the edges on the upper side and the lower side of the component. If the vertical and horizontal position indicators of the display system are used, a point is selected at the lower side edge of the component to start the selection operation, then the selection operation is performed at the key point again along the vertical direction, and finally the selection operation is finished after a point is selected at the upper side edge along the vertical direction. Then, the pixel coordinates of the first to-be-measured point (selected operation start position), the intermediate pixel coordinates at the key point, and the pixel coordinates of the second to-be-measured point (selected operation end position) in the selected operation are acquired.

Step S202, drawing a first line segment based on pixel coordinates of a first to-be-measured point and a second to-be-measured point.

In this embodiment, the first line segment is drawn based on the pixel coordinates of the first to-be-measured point and the second to-be-measured point, so as to provide a basic condition for drawing the virtual measurement scale.

Step S203, drawing a second line segment on the first line segment according to a first step length based on the length and the azimuth angle of the first line segment, and obtaining a scale line.

In this embodiment, the scale mark is obtained by drawing the second line segment on the first line segment according to the first step length based on the length and the azimuth angle of the first line segment, so as to provide a necessary condition for creating the virtual measurement scale.

In an alternative embodiment, the position and the length of the scale are determined based on the pixel coordinates of the first to-be-measured point and the pixel coordinates of the second to-be-measured point, and the scale line drawing of the first to-be-measured point and the second to-be-measured point and the scale line drawing of the key point are performed on the scale.

In an alternative implementation manner, first, a first line segment length and an azimuth angle between pixel coordinates of a first to-be-measured point and pixel coordinates of a second to-be-measured point are calculated, an indication direction and a measurement length of the first line segment are determined based on the first line segment length and the azimuth angle, then a first step length is determined based on the indication direction and the measurement length, starting point coordinates and end point coordinates of each second line segment are circularly calculated based on the first step length, starting point coordinates and end point coordinates of each second line segment are searched once every first step length based on the set height of the second line segment, and second line segment line drawing is carried out, so that a scale mark of the scale is obtained. The scale may have a linear structure or a scale-like structure.

Referring to fig. 3, for example, when calculating a first line segment length between a first to-be-measured point pixel coordinate (start coordinate) a (X1, Y1) and a second to-be-measured point pixel coordinate (end coordinate) B (X2, Y2), i.e., a distance s_ab between A, B, s_ab=math.sqrt ((X2-X1) ×2-X1) + (Y2-Y1) ×y 2-Y1). Since the scale is required to mark the scale value at a fixed distance in addition to displaying the total length. Therefore, the azimuth f_ab is also calculated, and the two-point coordinates of a (X1, Y1), B (X2, Y2) are known, and the azimuth f_ab of ab=math.

Further, knowing the pixel coordinates a (X1, Y1) of the first to-be-measured point, the azimuth of the first line segment AB, setting the small scale interval value to be 30px, and then circularly calculating the start coordinate and the end coordinate of each scale line. The pixel coordinates a (X1, Y1) of the first measurement point, the azimuth f_ab of AB, the distance s_ab between AB are known. The C point coordinates (X0, Y0) and the D point coordinates (X00, Y00) are obtained.

Setting the height step=10px of the small scale, performing scale line drawing every 30PX, that is, finding the coordinates of the line segment CD of 10px on the first line segment AB at the beginning of every 30PX of the length, and performing anticlockwise 90 ° rotation line drawing.

X0＝X1+step*Math.cos(F_AB)；

Y0＝Y1+step*Math.sin(F_AB)；

X00＝X1+step*Math.cos(F_AB)；

Y00＝Y1+step*Math.sin(F_AB)；

If X2< X1 (drawn from right to left), the pixel coordinates of the first point to be measured and the pixel coordinates of the second point to be measured are interchanged:

X0＝X2+step*Math.cos(F_AB)；

Y0＝Y2+step*Math.sin(F_AB)；

X00＝X2+step*Math.cos(F_AB)；

Y00＝Y2+step*Math.sin(F_AB)；

The small scale coordinate is vertical to the AB, the line segment CD is parallel to the AB, and a 90-degree rotation operation of the graph is needed when the scale line is drawn, for example, the selection operation based on fabric. Js only needs to set the value of the angle attribute to be-90, and the angle attribute is rotated around the upper left corner coordinate of the graph.

var line0＝new fabric.Line([X0,Y0,X00,Y00],{stroke:'black',angle:-90,})；

I.e. the graduation marks can be drawn vertically, and then the operation as the CD searching is performed once every 30px distance on the first line segment AB is circulated until the last point on the first line segment AB meets the condition.

In an alternative implementation manner, firstly, calculating the length and azimuth angle of a line segment between the pixel coordinates of a first to-be-measured point and the middle pixel coordinates, determining the indication direction and the measurement length of a graduated scale based on the length and the azimuth angle of the line segment, determining a first step length based on the indication direction and the measurement length, circularly solving the starting point coordinates and the end point coordinates of each second line segment based on the first step length, searching the starting point coordinates and the end point coordinates of each second line segment once every first step length based on the set height of each second line segment, and drawing the second line segment. Then, determining the indication direction and the measurement length of the graduated scale based on the length and the azimuth angle of a line segment between the middle pixel coordinates of the key point and the pixel coordinates of a second point to be measured of the second point, circularly solving the starting point coordinates and the end point coordinates of each second line segment based on the indication direction, the measurement length and the first step length, searching the starting point coordinates and the end point coordinates of each second line segment once every first step length based on the set height of the second line segment, drawing the second line segment lines to obtain graduated lines, and further obtaining the graduated scale to be marked.

And step S204, based on the length of the first line segment, marking the scale marks according to the second step length to obtain the virtual measurement scale.

In this embodiment, the scale marks are marked according to the second step length based on the length of the first line segment, so as to obtain a virtual measurement scale, so as to realize the distance measurement between two components as shown in fig. 4.

In an alternative embodiment, the positions of the scale marks are used for scaling the scale marks according to a second step length to obtain a virtual measurement scale for measuring the distances between the first to-be-measured point and the key point and between the first to-be-measured point and the second to-be-measured point, so that the distance measurement between two sides of an image of a component and between the key point and two sides of the current side is realized.

In an alternative embodiment, the scale value of each second line segment is calculated according to the measured length, and scale value marking is performed once every preset number of scale lines based on the scale value of each scale line. The virtual measurement graduated scale has zero starting point graduated value and zero ending point graduated value in the indicating direction as measurement length.

In an alternative embodiment, the scale value of each scale line is calculated based on the distance between the pixel coordinate of the first to-be-measured point and the middle pixel coordinate, and then scale value marking is performed once every preset number of scale lines. And then calculating the scale value of each scale line between the middle pixel coordinate and the pixel coordinate of the second to-be-measured point based on the distance between the pixel coordinate of the first to-be-measured point and the pixel coordinate of the second to-be-measured point, and then marking the scale value every other preset number of scale lines.

For example, based on step S202, the scale measurement length is marked at the B position according to the value of s_ab, and a value is marked every 5 scale marks, that is, every 150 px. The marked position is based on solving C point coordinates to draw numerical characters.

Step S205, determining a distance between the first point to be measured and the second point to be measured based on the virtual measurement scale.

In this embodiment, the distance between the first to-be-measured point and the second to-be-measured point is determined by the virtual measurement scale, so that accuracy and efficiency of measurement of each component and dimensions among components in the quantum chip design can be improved, and guarantee is provided for normal operation, smooth manufacturing, cost saving and system stability of the quantum chip.

Based on step S201, because the pixel coordinates of the first to-be-measured point (the selected operation start position), the middle pixel coordinates of the key point and the pixel coordinates of the second to-be-measured point (the selected operation end position) are obtained in the process of creating the virtual measurement scale, and scales of the positions are marked in the scale marking, the measurement distance and the scales of the corresponding key points can be directly read, and the situation that the scales are inaccurate in reading when the positions of the scale lines do not completely correspond to the key points due to the fixed interval drawing of the scale lines in the process of creating the scales is avoided.

In an optional implementation manner, an association relationship between the virtual measurement graduated scale and the corresponding point to be measured can be created, and when the position of the point to be measured is changed, redrawing is performed on the virtual measurement graduated scale according to the position change information of the point to be measured, so as to realize dynamic measurement of the distance between the two points to be measured; the complexity of the operation that the measurement needs to be carried out again after the user adjusts the distance between the two points to be measured by feeling is avoided, and the accuracy of the position adjustment is low. In the enlarged and reduced view of the canvas, the scale mark interval of the virtual measurement scale is dynamically adjusted according to the current scaling factor multiplied by the interval value of the original scale.

According to the distance measurement method based on the virtual measurement graduated scale, pixel coordinates of a first to-be-measured point and a second to-be-measured point are obtained, so that measurement of distances between two points on the same component graph or between two points on two component graphs is conveniently performed based on the first to-be-measured point and the second to-be-measured point; drawing a first line segment based on pixel coordinates of a first to-be-measured point and a second to-be-measured point, drawing a second line segment on the first line segment according to a first step length based on the length and azimuth angle of the first line segment to obtain a scale mark, providing necessary conditions for drawing a virtual measurement scale, and marking the scale mark according to the second step length based on the length of the first line segment to obtain the virtual measurement scale; the distance between the first to-be-measured point and the second to-be-measured point is determined through the virtual measurement scale, so that accuracy and efficiency of measurement of each component and the size between components in quantum chip design can be improved, and guarantee is provided for normal operation, smooth manufacturing, cost saving and system stability of the quantum chip.
