Detailed Description
The embodiment of the application discloses a method for measuring spectrum information, a spectrometer and a storage medium, which are used for improving the accuracy of spectrum measurement and improving the measurement efficiency of a user.
In order that those skilled in the art will better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments.

Rather, use of words such as, or by way of example, is intended to present related concepts in a concrete fashion.
In the description of the embodiments of the present application, the term plurality means two or more. For example, a plurality of systems means two or more systems, and a plurality of screen terminals means two or more screen terminals. Furthermore, the terms first and second are used for descriptive purposes only and are not to be interpreted as indicating or implying a relative importance or implicitly indicating an indicated technical feature. Thus, a feature defining a first or second may explicitly or implicitly include one or more such feature. The terms including, comprising, having, and variations thereof are meant to encompass, but not be limited to, unless otherwise specifically emphasized.
The technical scheme provided by the application can be applied to spectrum measurement. Fig. 1 is a schematic diagram of a scenario in which a spectrometer is used to perform spectral measurement in the related art.
As shown in fig. 1 (a), the user wants to measure the spectrum of the root of the grass on the ground outdoors, he holds a spectrometer which is about one meter away from the ground and emits laser light on the ground.
Fig. 1 (b) is a view of the spectrometer facing the measurement object: 1, a spectrometer is arranged on one surface of a measured object, which is used for receiving optical information and performing spectral measurement; 11 is a photographic lens for taking a photograph, which can be used to observe and record object appearance information; 12 is an angle lens for receiving light information for measurement, the angle of view of the angle lens is generally smaller, and the measurable range is smaller; reference numeral 101 denotes a spot laser pointer for emitting laser light, which is applied to an object to indicate a measurement position.
In fig. 1, (c) is a view of the spectrometer facing the user, and is a display screen: 2 is a display screen interface of the spectrometer facing the user, which is used for displaying the view of the measured object, so that the user can observe and record the appearance information of the object conveniently; reference numeral 21 denotes an object view taken by the camera lens 11; 102 is a laser indicating point of the point laser indicator 101 on the ground.
The user determines the laser pointer 102 as a measurement position based on the position of the laser pointer, and performs spectral measurement.
However, since the angle of view lens is not coaxial with the laser pointer, there is an offset in the position detected by the lens relative to the laser light emitted from the pointer, and the actual measured position of the user is different from the laser pointing position. Meanwhile, under the condition that a user does not have experience, the measurement range cannot be accurately judged. In the case of uncertainty in both position and range, the spectrum test accuracy is low, and the user performs the measurement at this time, and the result is necessarily not satisfactory. For example, in the above scenario, the user wants to measure the root of the grass, but due to the deviation, the laser hits the root of the grass, but the actual measurement is the spectral information of the grass blades.
As with the above analysis, the user finds that the measurement result is inconsistent with the reference result given by the instructor after making the measurement. And then he goes to the teacher, and the teacher makes him get closer to the spectrometer to the ground, and at the same time, pay attention to observe not only the laser indication point, but also the position of the angle lens, and measure again, so as to finally obtain a result similar to the standard.
The guidance is empirical, and the closer to the ground is to narrow the measurement range, the larger the distance is, the larger the range can be measured, and other disturbances may exist in the large range. Besides the laser point, the lens position is observed, which means that the laser indication has deviation, and the human eyes are required to specifically judge the specific measuring position.
In the above-mentioned scenario, since the installation position of the spot laser pointer 101 is not coaxial with the angle-of-view lens 12, the laser spot 102 cannot accurately indicate the measurement position, and an error occurs in the judgment of the user, resulting in inaccurate measurement.
The user in the scene has a reference result, and can check whether the spectrum measurement is accurate or not in comparison. However, in other scenes, the same reference result cannot be ensured, and the accuracy of the result cannot be judged, so that the accuracy of the indication is particularly important.
By adopting the method for measuring the spectrum information, provided by the embodiment of the application, the measuring position is precisely positioned through laser intersection, the measuring area is calculated in real time and is visually displayed through the screen, so that a user can easily identify the current detecting area, the measuring accuracy of the user is greatly improved, and the working efficiency is improved. Referring to fig. 2, a schematic view of a spectrum measurement scenario is provided in an embodiment of the present application.
As shown in fig. 2 (a), the user wants to measure the spectrum of the root of the grass on the ground outdoors, he holds a spectrometer which is about one meter away from the ground and emits a cross laser to hit the ground.
In fig. 2 (b), a view of a spectrometer facing a measured object is shown, 201 and 202 are linear laser indicators, the linear lasers emitted by the two indicators are intersected and combined into a cross, and the cross line is the central axis of the angle-of-view lens 12, so that when the laser cross strikes the object, the central position of the cross is the central position of the measured area of the angle-of-view lens.
In fig. 2 (c) is a view of the spectrometer on the side facing the user, 203 is the laser cross, and the intersection of the laser crosses 203 is the center position of the derived measurement; 204 is a measurement area display, and a specific measurement range can be accurately displayed on a screen.
The user accurately judges the center of the measuring position according to the position of the crossing point of the laser cross 203. And the measurement area is found to be larger through the screen area display 204, so that the height of the spectrometer is reduced to reduce the measurement range. After determining the range, the spectral measurement is performed, and the user obtains a result similar to the reference.
The spectrum measuring method in the embodiment of the present application will be described below in conjunction with the above-described scenario. Fig. 3 is a schematic flow chart of a spectrum measurement method according to an embodiment of the application.
S301, displaying a current measurement area by a spectrometer;
the spectrometer is provided with a distance measuring device which can directly measure the distance between an object and the lens of the field angle of the spectrometer. After the spectrometer is started to measure, the distance from the current spectrometer to the surface of the object to be measured is measured, and the distance is the object distance.
After the current object distance is measured by the spectrometer, the current measuring area center point is determined through the laser crossing center point by combining the field angle parameters of the field angle lens.
The laser intersection is obtained by intersecting laser emitted by two linear laser indicators of a spectrometer, as shown in middle 201 and 202 of fig. 2 (b), because the linear laser emitted by the two indicators intersects with the central axis of the view angle lens, the central axis is the central line extending from the view angle lens, as shown in 203 of fig. 2 (c), the intersection center of the laser on the surface of the object to be measured is the intersection point of the central axis of the view angle lens and the surface of the object to be measured, and this point is the central point of the current measurement area.
In some embodiments, the line of lasers are perpendicularly intersected, in which case a laser cross will be obtained on the object plane, which is generally more advantageous with respect to positioning in both the horizontal and vertical directions, the laser cross center point being the measurement area center point.
The spectrometer will identify the location of the center point of the current measurement region. Specifically, the spectrometer adopts an image recognition mode to recognize laser intersections in the image, and then further determines the laser intersections, wherein the laser intersections are the central point positions of the measuring areas.
The spectrometer can calculate the radius of the current measuring range according to the field angle parameters of the field angle lens of the spectrometer and the current object distance, and further can determine the area. And combining with the identification of the center point of the measurement area, the range of the current measurement area on the image can be accurately calculated. As shown at 204 in fig. 2 (c), the current measurement area may be displayed graphically on a screen for the convenience of the user to calibrate and measure.
S302, adjusting the current measurement area to an area to be measured by a spectrometer based on adjustment operation of a user;
after the current measurement area is observed, the user can adjust the current measurement area according to the requirement so as to enable the measurement range to meet the requirement. In the adjustment process, the spectrometer calculates the adjusted current measurement area according to the field angle parameters of the field angle lens, the adjusted current object distance and the center point of the current measurement area, and displays the adjusted current measurement area on the screen of the spectrometer in a graphic form as shown in 204 in fig. 2 (c).
In some embodiments, after observing the current measurement area, the user adjusts the distance from the spectrometer to the surface of the object to be measured, and adjusts the position of the spectrometer until the current measurement area meets the requirements. When the user confirms the final adjustment, the measurement is started, and the current measurement area is the area to be measured.
S303, measuring spectral information of the region to be measured by a spectrometer.
This step is entered after the user confirms that the spectroscopic measurement is being performed. The spectrometer collects the spectrum information in the current region to be measured, performs statistical analysis on the spectrum information, displays the result on a screen in the form of a spectrogram and the like, and feeds back the result to a user.
As can be seen from the above embodiments, compared to the related art in which a spectrometer is used to perform spectral measurement, the embodiment of the present application adopts a visualization method, in which the center of the measurement area is indicated by a laser cross, the measurement area is displayed by a screen graphic, and the screen graphic is updated in real time according to user adjustment. The user uses the laser cross and the screen display as the standard, so that the calibration and the positioning of the measurement area can be quickly performed, on one hand, the accuracy of spectrum measurement is improved, on the other hand, the efficiency of spectrum measurement by the user is also improved, and the use experience of the user spectrometer is optimized.
The application also provides a spectrometer, with reference to fig. 4, which essentially comprises a measuring part 1 of the spectrometer and a holder 4. The measuring section 1 of the spectrometer may be used to implement the above embodiment, and the stand 4 may then provide automatic and accurate movement support for the measuring section of the spectrometer, the stand 4 body part comprising:
legs 41 for fixing the whole apparatus;
an x-axis movement 42 for moving the measuring section 1 of the spectrometer fixed to the holder 4 in an x-axis direction, which is one direction in a horizontal plane;
a y-axis movement 43 for moving the measuring section 1 of the spectrometer fixed to the holder 4 in a y-axis direction, the y-axis direction being perpendicular to the x-axis in a horizontal plane;
The z-axis of movement 44 is generally not moved, and the entire apparatus, including the x-axis of movement 42, the y-axis of movement 43, and the measuring section 1 of the spectrometer, can be moved up and down in the z-axis direction, which is vertical to the horizontal plane in which the x-and y-axes are located.
By moving both the x-axis of movement 42 and the y-axis of movement 43, a wide range of objects can be measured, the overall movable area being shown as 401 in fig. 4.
The following is a description of the use scenario of the spectrometer:
the user goes outdoors and wants to take measurements in several places in a certain area, so he secures the holder 4 and installs the measuring part 1 of the spectrometer in place.
The user selects the scanning option of the spectrometer, the spectrometer automatically moves, and the spectrometer is reset after the camera takes photos of all positions in the area.
Referring to fig. 5, fig. 5 is a schematic view of a scenario of the spectral information measurement. As shown in fig. 5 (a), a master map 5 is displayed on the spectrometer screen, and this master map 5 is the entire area that the spectrometer can capture in the movable area 401. The area 51 is shown in bright color and is an area where measurement can be performed. The user clicks the measurement area 51 to perform measurement selection, and the selected areas 511, 512 and 513 are respectively selected by the user to be the measured selected area 1, selected area 2 and selected area 3, wherein the selected area 513 does not confirm the selection yet, 52 is a selection prompt box to prompt the user to perform selection confirmation, the user can determine the position of the selected area by clicking "confirm" and cancel "by clicking" cancel ".
The user clicks "ok" in the selection box 52 and turns on the spectrometer measurement, and the spectrometer quickly moves in sequence over the positions of the designated selections 511, 512, and 513 for measurement, and the spectrometer is reset after the measurement is completed.
At this time, as shown in fig. 5 (b), a parent map is displayed on the screen of the spectrometer, and the selected area 511, the selected area 512, and the selected area 513 on the map show corresponding spectrum measurement result maps 531, 532, and 533, respectively.
The user obtains the spectral results in three areas in a short time, and obtains the desired results after performing statistical analysis.
Specific method steps are described below in connection with the use scenario described above. Please refer to fig. 6, which is a flow chart of the spectrum measuring method.
S601, displaying a current measurement area by a spectrometer;
when the measuring part of the spectrometer is arranged on the bracket, wireless connection can be established between the measuring part and the bracket. The spectrometer sends out instruction signals, as shown in fig. 4, after the bracket receives the signals, the x-moving axis 42 and the y-moving axis 43 are moved according to the instructions, and the measuring part of the spectrometer can scan, photograph or measure the spectrum of different areas.
After the power-on, the spectrometer will move the measurement part to an initial position, where the initial position is the zero point of the stand device, and is the position where neither the x-movement axis nor the y-movement axis is moved, and is located in the lower left corner of the entire movable area 401. In the initial position, the spectrometer displays the current measurement area, and the range size of the current measurement area can be used for subsequent area selection operation.
S602, responding to user operation, and scanning all images in a movable area by the spectrometer;
after a start instruction of a user is obtained, the spectrometer can move in the x-axis direction and the y-axis direction in the movable range, and simultaneously performs scanning photographing. The spectrometer will quickly collect all image information within the movable region 401 in a short time.
S603, the spectrometer synthesizes the scanned images, and a mother map containing all images of the movable area is displayed on a screen;
after all the image information in the movable area 401 is collected, the spectrometer will splice all the pictures, fit into a mother map of the whole area, and display on the screen. As shown in fig. 5, a parent map 5 within the moving area is displayed on the screen.
Since the angle of view lens is smaller than that of the photographing lens, the actual measurement range is narrower, and the area to be distinguished from the area to be combined by photographing is designated as 51.
In some embodiments, the area 51 to be detected and the non-detection area on the map are shaded, so that the user can clearly identify the detection area.
S604, responding to one or more selection operations of a user on the mother map, wherein one or more selection marking areas appear on the mother map;
After obtaining a parent map of the entire area, the user may select the area for measurement. As shown in fig. 5 (a), the user clicks on the map on the screen to select a region, and the size of the selected frame is consistent with the range of the current measurement region in step S601, and the selected region is shown as 511, 512 and 513 as a selected region marking region, which is also described as a selected region hereinafter.
The default size of the selection area is calculated by referring to the previous embodiment and the angle of view and the object distance of the angle of view lens. The object distance is the distance between the field angle lens of the spectrometer on the bracket and the surface of the current measured object, and is measured by the distance measuring device of the spectrometer.
In some embodiments, the user may choose to actively change the size of the selection, with the default size of the selection being referred to herein as a regular selection and the selection after the change in size of the selection being referred to as an irregular selection. The number of the two selection areas is not limited. For non-conventional selection, the spectrometer needs to be moved in the z-axis for subsequent measurements to fit different size ranges.
In some embodiments, a user may zoom in or zoom out on a map with two fingers on the spectrometer screen to facilitate formulation of the selection area. Correspondingly, the conventional selection range can automatically perform operations such as zooming in and zooming out.
In some embodiments, after the user clicks to select a region, a prompt message appears on the screen to prompt the user to confirm the selected region, and 52 in fig. 5 is the prompt message, where two options are available for the user to select, the user clicks the "ok" option to determine the selected region, and the user clicks the "cancel" option to cancel the selected region.
In some embodiments, the user may select the area multiple times at multiple locations.
Specifically, the following conditions are present when selecting a region:
1. the user can confirm a selected area by clicking the map, and if a plurality of positions on the map are to be measured, clicking selection is carried out at the corresponding plurality of positions for one time;
2. the user can confirm a selected area by clicking the map, and if the user wants to measure the same position on the map for multiple times, the user can click and select for multiple times at the same position;
the selection of the regions in both cases may comprise conventional or non-conventional selection of regions. And in some embodiments, one or both of the above-described selection cases are often included.
S605, the spectrometer determines the one or more selection area marking areas as one or more areas to be measured, and adjusts the current measurement area to the one or more areas to be measured;
after the user confirms to measure, the bracket moves, and the spectrometer is moved to the appointed selective marking area according to the selective sequence, namely, the current measuring area is sequentially adjusted to one or more areas to be measured.
In some embodiments, to increase the efficiency of operation, the spectrometer may measure out of the order of the selection, the spectrometer may plan a shortest route that can measure all the selections, and instruct the support to move along the shortest route. For the irregular area selection in some embodiments, although the position center can be positioned according to the laser cross, the size of the irregular area selection is inconsistent with the current measurement range, and the bracket can move up and down along the z-axis so as to enable the current measurement area to adapt to the corresponding irregular area selection size.
In particular, the following principles may be followed when route planning is performed:
1. the x-axis, y-axis and z-axis can move simultaneously from one position to the next to ensure that the path is the shortest straight line;
2. dividing the selected areas, and carrying out measurement in a centralized manner by concentrating the selected areas together, so that unnecessary distance consumption during back and forth measurement is avoided;
3. for the unconventional selection area, a unidirectional principle is generally adopted, namely, the measurement is sequentially carried out from large to small or from small to large according to the selection area range, and at the moment, the z-axis only needs to move in one direction and is not used for returning movement to waste efficiency.
With the above several principles in mind, route planning may be performed as follows:
1. The spectrometer splits the mother map into a plurality of sub maps, and the sub maps ensure that the density of the selected area is as large as possible; the selected area density refers to the number of selected area parts in the unit submap area, and the more the selected area parts are, the higher the density is;
2. comparing the running routes of a plurality of areas to be measured in the measuring sub-map by the spectrometer, and planning a route with the shortest route;
3. the spectrometer plans the shortest route connecting all the sub-maps, and the connected whole route is defined as the final measurement operation route.
After the route planning is executed, the spectrometer can operate according to the planned route, so that the current measurement area sequentially corresponds to a plurality of areas to be measured, and subsequent measurement is facilitated.
S606, detecting spectral information of the one or more areas to be measured by a spectrometer.
And taking the selected area as the area to be measured, and measuring the spectrum information of the area to be measured when the spectrometer sequentially reaches the appointed area to be measured.
In some embodiments, after the spectral information of all the selected areas is measured, the spectrometer displays the map of the spectrometer, as shown in fig. 5 (b), 531, 532, 533 are displayed spectrograms, and the user can collect and analyze the spectral information in a large range according to the spectrograms, so as to improve the measurement efficiency.
In some embodiments, the user may click on a spectrogram displayed on the parent map to enter a detail page on which more information of the corresponding region, e.g., corresponding photograph, distance, etc., is displayed.
It can be understood that the method for measuring spectral information provided by the above embodiment is implemented, not by a user holding the spectrometer for calibration detection, but by displaying a visual map in the range area. The user can directly select the corresponding areas in batches, the automatic detection of a plurality of areas in a range can be realized, and the detection result condition of each area can be simply observed after the detection. The visual display is more beneficial to the analysis of the data in the area by the user, so that the detection accuracy and the detection efficiency are improved, and the use experience of the user is improved.
