Referring to fig. 2, in an embodiment of the method for testing the size of the light curtain of the present invention, the method for testing the size of the light curtain includes the following steps:
step S10, acquiring a first mapping relation corresponding to the light-emitting angle of view and the distance of the light source and the distance to be tested, wherein the distance is the spacing distance between the light source and the whiteboard;

and step S40, determining a test result according to the light curtain size and the reference light curtain size corresponding to the distance to be tested.
In order to detect whether the light curtain formed by the light source at the minimum size corresponding to the distance meets the standard, the size of the light curtain formed by the light source needs to be tested at different distances. In the conventional test process, it can be determined whether the light source satisfies the standard at each distance only by performing a dimensional test at each distance to be tested. Therefore, when the distance to be tested is large, the position of the light source needs to be moved frequently, which results in a complicated testing procedure, and thus has a drawback of low testing efficiency.
To solve the above-mentioned drawbacks, an embodiment of the present invention provides a method for testing a light curtain size.
When the light curtain dimension test is carried out, a light curtain dimension test system can be set up firstly. As shown in fig. 3, the light curtain dimension testing system includes a light source to be tested, and a white board. The white board comprises a first sub white board parallel to a light-emitting surface of the light source, and a second sub white board and a third sub white board which are perpendicular to the first sub white board and connected to two ends of the first sub white board respectively. The light emitted by the light source forms a rectangular light curtain in a space enclosed by the first sub-white board, the second sub-white board and the third sub-white board. The size of the rectangular light curtain can be determined by the length value of the light generated by the light curtain on the first sub-white board, namely the length of the rectangular light curtain, and the length value of the light generated by the light curtain on the second sub-white board or the third sub-white board, namely the width value of the rectangular light curtain.
In this embodiment, the light source may be first set at a fixed position, that is, the distance between the light source and the whiteboard is kept at a preset distance, and the width value of the rectangular light curtain formed when the light source is at the position and emits light at different viewing angles is determined by adjusting the viewing angle of the light source.
Specifically, referring to fig. 3, setting the distance between the light source and the whiteboard to h1, a width value x1 of the light curtain produced when the light source is emitting light at field angle a is obtained, and a corresponding width value x2 of the light curtain when the light source is emitting light at field angle b is obtained.
Referring to fig. 4, fig. 4 is a top view of the testing system corresponding to fig. 3, when the length of the first sub-white board is 2y, the length of the rectangular light curtain is also 2 y. Thus, it can be derived:
tan a＝y/(h1-x1)
tan b＝y/(h1-x2)
since y and h1 are both fixed constants in the above equation, the light curtain width value changes according to the change in the angle of view, that is, there is a corresponding change relationship between the light curtain width value and the angle of view. Therefore, based on the acquired plurality of two field angles and the corresponding light curtain width values, the first mapping relationship between the field angles and the light curtain width values can be obtained. Specifically, the field angle o and the light curtain width value x may be used as input parameters of a function curve fitting tool such as MATLAB, and a second mapping relationship corresponding to the field angle o and the light curtain width value x may be fitted by the function curve fitting tool such as MATLAB.
For example, the second mapping relationship between the field angle o and the light curtain width value x may be represented as:
x＝K1o+b1
wherein, K1B1 is the intercept.
Further, it is also possible to control the light-emitting angle o of the light source to be saved as c and then move the light source to change the distance h between the light source and the whiteboard. Referring to fig. 5, when the distance between the light source and the whiteboard is h2, the width of the formed light curtain is x3, and when the distance between the light source and the whiteboard is h3, the width of the formed light curtain is x 4.
Therefore, when the distance between the light source and the whiteboard is changed, the light curtain width value corresponding to each distance can be acquired. Therefore, a third mapping relation corresponding to the distance h and the light curtain width value x can be fitted through a mathematical fitting tool: x is K2h + b 2. Wherein, K2B2 is the intercept.
After the second mapping relationship and the third mapping relationship are fitted, the viewing angle and the third mapping relationship may be determined according to the second mapping relationship and the third mapping relationshipAnd a first mapping relation corresponding to the distance. I.e. by x ═ K1o + b1, and x ═ K2h + b2, o ═ k2h + b2-b1)/k 1.
Further, after the corresponding relationship between the distance and the viewing angle is determined, in a later test, the light-emitting viewing angle of the light source at a fixed distance can be obtained according to the required distance. And the light source is controlled to emit light according to the angle of view determined by the distance, so that the light curtains corresponding to different distances are generated under the condition of not moving the position of the light source. In the testing process, a first mapping relation between the light-emitting angle of view of the light source and the distance to be tested are obtained, then a target angle of view corresponding to the distance to be tested is determined according to the first mapping relation, the size of the light curtain formed when the target angle of view is used as the light-emitting angle of view of the light source is obtained, and the testing result corresponding to the distance to be tested is determined according to the size of the light curtain.
Before determining the test result corresponding to the distance to be tested according to the light curtain size, the standard light curtain size corresponding to the distance to be tested is required to be obtained. The standard light curtain size corresponding to the distance to be tested can be actively input by a tester, or can be pre-stored in the light curtain size testing equipment.
Further, when the size of the light curtain of the currently formed light curtain is smaller than the size of the standard light curtain, the test result corresponding to the distance to be tested is judged to be abnormal, otherwise, the test result corresponding to the distance to be tested is judged to be normal.
In the technical solution disclosed in this embodiment, a first mapping relationship corresponding to a light-emitting angle of view of a light source and a distance to be tested are obtained, where the distance is a separation distance between the light source and a whiteboard, then a target angle of view corresponding to the distance to be tested is determined according to the first mapping relationship, and a light curtain size of a light curtain formed on the whiteboard when the light-emitting angle of view of the light source is the target angle of view is obtained, so as to determine a test result according to the light curtain size and a reference light curtain size corresponding to the distance to be tested, and since the corresponding angle of view can be directly determined according to the distance, in a light curtain size test process, a position of the light source can be unmoved, and an effect of testing the size of a corresponding light curtain at different distances is achieved by changing the light-emitting angle of view, thereby simplifying a step of the light curtain size test, thereby the effect of improving the testing efficiency is realized.
Referring to fig. 6, based on the above embodiment, in another embodiment, after step S40, the method further includes:
step S50, obtaining the test results corresponding to a plurality of different distances to be tested;
step S60, generating test statistical data according to the plurality of distances to be tested and the test results corresponding to the plurality of distances to be tested one by one.
In this embodiment, the light curtain dimension test interfaces corresponding to a plurality of different distances to be tested may be obtained, and then test statistical data may be generated based on the distances to be tested and the corresponding test results according to the plurality of distances to be tested and the test results corresponding to the plurality of distances to be tested, where the test statistical data may be a test chart.
For example, the test chart may be as shown in table 1 below:
in the table, a is the light curtain length value.
Optionally, after the step S60, the method further includes: and outputting the test chart.
Specifically, the test chart may be displayed in a display device or transmitted to a server to be held in a database of a value server.
Optionally, when the test chart is displayed, the distance to be tested whose corresponding test result is abnormal may be highlighted in the test chart. The highlighting manner includes a manner of font thickening, italics, background color adding, and/or special font displaying, which is not limited in this embodiment.
Optionally, after the test statistic data is generated, the test statistic data may be stored in a database of the local terminal, so that the test statistic data may be queried at a later stage. The test statistic data may also be sent to a target terminal, where the target terminal may be a server or a terminal corresponding to a person related to the test. When the target terminal is a server, after receiving the test statistical data, the test statistical data can be stored in a cloud server or other terminal devices corresponding to the test-related personnel. When the target terminal is a personal terminal, the test statistic data can be displayed and/or cached.
In the technical scheme disclosed in this embodiment, the test results corresponding to a plurality of different distances to be tested are obtained, and a test chart is generated according to the plurality of distances to be tested and the test results corresponding to the plurality of distances to be tested one to one. This achieves the effect of improving the processing efficiency of the test results.
