Illustratively, the camera includes a camera, which may be a general 2D camera, but may also be other cameras, such as a depth camera.

And executing the preset reminding operation, such as lighting a preset breathing lamp, broadcasting a preset reminding sound and displaying preset reminding information.

In some embodiments, the circuit board in the image is identified by identifying the image, and the two-dimensional position of the circuit board is determined, so as to determine the ideal installation position of the radio frequency connector according to the two-dimensional position of the circuit board. The two-dimensional position of the circuit board is the position of the circuit board on a plane rectangular coordinate system established on the plane where the circuit board is located, namely the position of the circuit board on the X axis and the position of the Y axis on the plane rectangular coordinate system.
In some embodiments, image features in the image are identified according to a pre-trained machine learning algorithm, feature point coordinates in the image are determined, and thus a two-dimensional position of the circuit board is determined according to the feature point coordinates.

For example, the coordinates of the feature points may be set in advance, that is, after the feature points are determined in the image, the coordinates of the feature points may be determined based on the coordinates of the feature points set in advance. For example, if the coordinates of the first feature point a on the circuit board are preset to be (0, 0), when the first feature point a in the image is determined, the coordinates of the first feature point a in the image may be determined to be (0, 0), and then the two-dimensional position of the circuit board is determined according to the coordinates of the first feature point. By presetting the first characteristic point coordinates, the calculation amount can be reduced, the speed of determining the two-dimensional position of the circuit board is increased, and the detection efficiency of the radio frequency connector is improved.
Illustratively, the first feature point may be a specific color block, such as a black color block, disposed on the circuit board, or may be a corner point of the circuit board.

For example, the dimensions of a known circuit board are: length W, width V, and there is first characteristic point a on the circuit board, the coordinate of first characteristic point a is (0, 0), as shown in fig. 4, the coordinate of first characteristic point a is used as the origin, a rectangular coordinate system is established with two adjacent edges of the circuit board, the radio frequency connector connected with the circuit board is a regular quadrilateral and includes four second characteristic points: a. b, c, d, wherein the ab-side is parallel to the X-axis, the lengths of the ab-side and the cd-side are X1, the lengths of the bc-side and the cd-side are X2, determining ideal coordinates corresponding to four second feature points of the radio frequency connector connected with the circuit board according to the position relation between the radio frequency connector and the circuit board connected with the radio frequency connector, that is, the ideal position is, for example, (q × W, p × V) for ideal coordinates of a, (q × W + X1, p × V) for ideal coordinates of b, (q × W + X1, p × V + X2) for ideal coordinates of c, and (q × W, p × V + X2) for ideal coordinates of d, and q and p are constants, and the numerical values of q and p can be set by a user in a self-defined mode or automatically generated by a server/detection tool according to the position relation between the radio frequency connector and a circuit board connected with the radio frequency connector.
Illustratively, the second feature point may be a specific color block, such as a black color block, disposed on the radio frequency connector, or may be a corner point of the radio frequency connector.
And S103, determining the actual installation position of the radio frequency connector according to the radio frequency connector and the circuit board in the image.
Specifically, the image is identified to identify the circuit board and the circuit board in the image, and the actual mounting position of the radio frequency connector on the circuit board is determined. Illustratively, the actual mounting position of the radio frequency connector on the circuit board is determined according to a plane rectangular coordinate system established on the plane where the circuit board is located, that is, the X-axis and Y-axis positions of the radio frequency connector on the plane rectangular coordinate system are determined.
In some embodiments, the radio frequency connector and the circuit board in the image are identified according to a pre-trained machine learning algorithm, and feature point coordinates in the radio frequency connector and the circuit board are determined, so that the actual installation position of the radio frequency connector is determined according to the feature point coordinates. Specifically, according to a pre-trained machine learning algorithm, the radio frequency connector and the circuit board in the image are identified, feature points corresponding to the radio frequency connector and the circuit board are respectively determined, and the actual installation position of the radio frequency connector is determined according to the feature points. For example, the actual mounting position of the radio frequency connector on the circuit board may be determined according to a rectangular plane coordinate system established on the plane where the circuit board is located by the second feature point corresponding to the radio frequency connector.
Illustratively, the radio frequency connector comprises a plurality of second characteristic points, and the actual installation position of the radio frequency connector comprises actual coordinates of the characteristic points corresponding to the radio frequency connector.
For example, the dimensions of a known circuit board are: long W, wide V, and there is first characteristic point A on the circuit board, and first characteristic point A's coordinate is (0, 0), and the radio frequency connector who is connected with the circuit board includes four second characteristic points: a. b, c and d, determining actual coordinates corresponding to four second feature points of the radio frequency connector connected with the circuit board based on the image algorithm and the coordinates of the first feature point A, namely the actual coordinates of a are (Xa, Ya), the actual coordinates of b are (Xb, Yb), the actual coordinates of c are (Xc, Yc) and the actual coordinates of d are (Xd, Yd), and accordingly determining the actual installation position of the radio frequency connector.
And step S104, determining a distance value between the radio frequency connector and a circuit board connected with the radio frequency connector.
Specifically, a distance value between the radio frequency connector and a circuit board connected with the radio frequency connector is determined through a distance measuring instrument. For example, as shown in fig. 5, the distance measuring instrument 30 transmits a signal to the rf connector 20 and the circuit board 10 connected to the rf connector, and the distance value between the rf connector 20 and the circuit board 10 connected to the rf connector is determined by the time when the signal encounters the rf connector 20 and reflects back and the time when the signal encounters the circuit board 10.
Illustratively, a laser ranging instrument is mounted at the detection area to determine a distance value between the radio frequency connector and a circuit board connected with the radio frequency connector by using laser ranging. The specific position of the laser ranging instrument can be flexibly set according to actual needs, for example, the laser ranging instrument can be installed at the positions such as right above a circuit board and a radio frequency connector connected with the circuit board, so that the laser ranging instrument can send laser signals to the circuit board and the radio frequency connector connected with the circuit board, determine the time difference of returning of the laser signals through the time when the laser signals meet the circuit board and the time when the laser signals meet the radio frequency connector connected with the circuit board and the time when the laser signals meet the radio frequency connector and the radio frequency connector, and finally determine the distance value between the radio frequency connector and the circuit board connected with the radio frequency connector according to the time difference of returning of the laser signals. For example, a mapping table between time and distance may be preset, and a distance value between the rf connector and a circuit board connected to the rf connector may be determined according to a time difference of return of the laser signal and the mapping table.
The laser range finder includes a TOF (Time of Flight) sensor. For example, a TOF sensor is mounted at the detection region to determine a distance value between the radio frequency connector and a circuit board to which the radio frequency connector is connected. The specific position of the TOF sensor can be flexibly set according to actual needs, for example, the TOF sensor can be installed at a position such as a position right above a circuit board and a radio frequency connector connected with the circuit board, so that the TOF sensor can send optical pulses to the circuit board and the radio frequency connector connected with the circuit board, respectively receive the optical pulses returned from the circuit board and the radio frequency connector connected with the circuit board, respectively obtain the distances between the circuit board and the radio frequency connector relative to the TOF sensor by detecting the flight round-trip time of the optical pulses, and finally determine the distance value between the radio frequency connector and the circuit board connected with the radio frequency connector according to the distances between the circuit board and the radio frequency connector relative to the TOF sensor.
Illustratively, an ultrasonic ranging instrument is installed at the detection area to determine a distance value between the radio frequency connector and a circuit board connected with the radio frequency connector using ultrasonic ranging. The specific position of the ultrasonic ranging instrument can be flexibly set according to actual needs, for example, the ultrasonic ranging instrument can be installed at the positions such as right above a circuit board and a radio frequency connector connected with the circuit board, so that the ultrasonic ranging instrument can send ultrasonic signals to the circuit board and the radio frequency connector connected with the circuit board, determine the time difference of returning ultrasonic waves through the time of the ultrasonic signals reflected back by the circuit board and the time of the ultrasonic signals reflected back by the radio frequency connector connected with the circuit board, and finally determine the distance value between the radio frequency connector and the circuit board connected with the radio frequency connector according to the time difference of returning ultrasonic waves. For example, a mapping table between time and distance may be preset, and a distance value between the radio frequency connector and a circuit board connected to the radio frequency connector may be determined according to the time difference of return of the ultrasonic wave and the mapping table.
The ultrasonic distance measuring instrument comprises an ultrasonic distance measuring sensor. For example, an ultrasonic ranging sensor is mounted at the detection area to determine a distance value between the radio frequency connector and a circuit board connected to the radio frequency connector. The specific position of the ultrasonic distance measuring sensor can be flexibly arranged according to actual needs, for example, the ultrasonic distance measuring sensor can be arranged right above a circuit board and a radio frequency connector connected with the circuit board, and the like, so that the ultrasonic distance measuring sensor can send ultrasonic signals to the circuit board and the radio frequency connector connected with the circuit board, then respectively receive ultrasonic signals returned from the circuit board and the radio frequency connector connected with the circuit board, respectively obtain the distance between the circuit board and the radio frequency connector relative to the ultrasonic distance measuring sensor through the round-trip time of the ultrasonic signals, and finally determine the distance value between the radio frequency connector and the circuit board connected with the radio frequency connector according to the distance between the circuit board and the radio frequency connector relative to the ultrasonic distance measuring sensor.

Illustratively, the position offset of the ideal installation position and the actual installation position of the radio frequency connector is determined according to the ideal coordinate and the actual coordinate corresponding to the second characteristic point of the radio frequency connector. For example, the rf connector has four second feature points: a. the ideal coordinates of b, c, d and a are (xW, yV), the actual coordinates are (Xa, Ya), the ideal coordinates of b are (xW + X1, yV), the actual coordinates are (Xb, Yb), the ideal coordinates of c are (xW + X1, yV + X2), the actual coordinates are (Xc, Yc), the ideal coordinates of d are (xW, yV + X2), and the actual coordinates of d are (Xd, Yd).
In some embodiments, the outputting a detection result according to the position offset and the distance value specifically includes the following steps:
if the position offset is not greater than a preset offset threshold and the distance value is not greater than a preset distance threshold, judging that the installation of the radio frequency connector meets a preset standard, and outputting a detection result qualified in detection;
if the position offset is larger than a preset offset threshold, judging that the installation of the radio frequency connector does not meet a preset standard, and outputting a detection result that the detection is unqualified;
and if the distance value is larger than a preset distance threshold value, judging that the installation of the radio frequency connector does not meet a preset standard, and outputting a detection result that the detection is unqualified.
Specifically, the mounting of the rf connector needs to satisfy two conditions that the position offset amount between the ideal mounting position and the actual mounting position is not greater than a preset offset threshold value and the distance value between the rf connector and the circuit board is not greater than a preset distance threshold value. If the installation of one radio frequency connector meets the two conditions, determining that the radio frequency connector meets the preset standard, and outputting a detection result that the radio frequency connector is qualified; and if the two conditions are not met when one radio frequency connector is installed at the same time, determining that the radio frequency connector does not meet the preset standard, and outputting a detection result that the radio frequency connector is detected to be unqualified.
