Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, are within the scope of the present invention.
It should be noted that, the step numbers in the text are only for convenience of explanation of the specific embodiments, and do not serve to limit the execution sequence of the steps. The method provided by the embodiment can be executed by the relevant server, and the server is taken as an example for explanation below.
As shown in fig. 1 to fig. 3, the method for determining the position of a bead of an LED light string according to an embodiment of the present invention includes steps S11 to S13:
step S11, establishing connection between a light string control APP and an LED light string, and sending a jump instruction to the LED light string through the light string control APP so as to change the color of each lamp bead in the LED light string; and the color arrangement mode of each lamp bead is unique after the jumping is finished.
In this embodiment, a mobile terminal is taken as an example for description, but it should be understood that the embodiment of the present invention is not limited thereto, and the method of the embodiment of the present invention may be applied to any lamp control device, that is, any control device that can perform lamp control through connection.
Specifically, in this embodiment, in the process that the light string control APP runs on the mobile terminal, a communication (such as TCP or bluetooth) connection request initiated by the target device (LED light string) is obtained in real time, and the communication request is responded, so that establishment of TCP connection between the light string control APP and the LED light string is realized. After the LED lamp string and the lamp string control APP establish a connection request, the lamp string control APP calls lamp string jumping feet carried by the lamp string control APP to operate the lamp string jumping script, and corresponding jumping instructions are sent to all lamp beads in the LED lamp string according to the operation result of the lamp string jumping script. Meanwhile, the jump instruction sent to each lamp bead is sent according to the address of the lamp bead, and in other embodiments, the connection between the string control APP and the LED string may be wired connection, if the jump instruction is sent to the lamp bead with the address of 1, the jump instruction is sent to the lamp bead with the address of 2, and the jump instruction is sent to the lamp bead with the address of 3, such as … …. The specific connection mode of the wired connection and the wireless connection can be adjusted according to actual requirements.
Furthermore, the jumping color of each lamp bead in the LED lamp string comprises red, green or blue. In other embodiments, the color of each light bead hopping may further include other colors, but in this embodiment, the color of each light bead hopping is red, green, or blue in consideration of the accuracy of subsequent light bead color identification. Meanwhile, the frequency of sending the jump instruction to the LED lamp string by the lamp string control APP in the embodiment meets 3^ X >; wherein, X is the quantity of picture, and N is the quantity of lamp pearl.
It can be understood that through the design of lamp string control APP to improve the commonality of lamp string control, avoid only specific equipment can carry out lamp string control, other equipment can't carry out the problem of lamp string control. Meanwhile, the lamp string control APP sends the corresponding jump instruction according to the lamp bead addresses, so that unique lamp bead addresses composed of the lamp beads are obtained, and necessary conditions are provided for accurate determination of subsequent lamp bead positions.
And S12, after the color of the LED lamp string is changed, the lamp string control APP takes a picture of the LED lamp string at the same angle to obtain an LED lamp string jump image.
Specifically, work as the colour of each lamp pearl in the LED lamp cluster changes the back, to light string control APP sends a colour and changes the completion information, light string control APP is receiving after the colour of each lamp pearl changes the completion information in the LED lamp cluster, right the LED lamp cluster is shot, obtains LED lamp cluster jump image, and the follow-up in-process of shooing of LED lamp cluster keeps same angle.
And S13, after the shot LED lamp string jump image is the final jump image of the LED lamp string, identifying the positions and colors of lamp beads of all the LED lamp string jump images, and determining the actual positions of the lamp beads in the LED lamp string according to the color arrangement and the address of each lamp bead.
Specifically, after the shot LED lamp string hopping image is the final hopping image of the LED lamp string, the method further comprises the steps of obtaining all hopping colors of lamp beads in the same lamp bead address; establishing a lamp bead address matrix of the LED lamp string according to all hopping colors of lamp beads in the same lamp bead address; the lamp bead address matrix comprises lamp bead hopping colors corresponding to all lamp bead addresses.
For example, the first picture lamp bead address is 1, the lamp bead becomes RED, the lamp bead address is 2, the lamp bead becomes RED, and the lamp bead address is 3, the lamp bead becomes BLUE, that is [ RED, BLUE ]. The second picture lamp bead address is 1, 2 and 3, namely [ RED, RED, RED ]. The third picture has lamp bead address 1 changing from GREEN to BLUE, lamp bead address 2 changing from BLUE, and lamp bead address 3 changing from RED, that is [ GREEN, BLUE, RED ]. And then the lamp bead address matrix of the LED lamp string is as follows:
A＝[
RED,RED,BLUE
RED,RED,RED,
GREEN,BLUE,RED
]
and then transposing the matrix (A ^ T), wherein each row of the matrix is a unique address representing the lamp bead, each row has unique arrangement, and the arrangement is used for determining a corresponding position during picture identification.
Specifically, the identification of the positions and colors of the lamp beads is carried out on all the jump images of the LED lamp strings, and the actual positions of the lamp beads in the LED lamp strings are determined according to the color arrangement and the address of each lamp bead, including: calling an image recognition model YoloV3, and recognizing the positions and colors of all lamp beads in the jump images of all the LED lamp strings; calculating the distance between each lamp bead in the first LED lamp string jump image and the corresponding lamp bead in the rest LED lamp string jump images, and regarding the two lamp beads with the shortest distance as the same lamp bead; establishing a lamp bead position matrix of the LED lamp strings according to the colors and positions of the same lamp beads in all the LED lamp string jump images; and determining the actual position of each lamp bead in the LED lamp string according to the lamp bead address matrix and the lamp bead position matrix of the LED lamp string.
For example, referring to fig. 2, the lamp beads appear on the jump diagram of the LED light string, such as from left to right and from top to bottom,
position of the bead 1 [ x1, y1, x2, y2]
The position of the lamp bead 2 is [ x1, y1, x2, y2]. Wherein, x1, y1, x2, y2 represent the area that the lamp pearl occupies.
Then, the position and color of each lamp bead of each picture,
a first picture:
[
[RED,x1,y1,x2,y2]
[RED,x1,y1,x2,y2]
[BLUE,x1,y1,x2,y2]
]
the second picture:
[
[RED,x1,y1,x2,y2]
[RED,x1,y1,x2,y2]
[RED,x1,y1,x2,y2]
]
the third picture: [
[GREEN,x1,y1,x2,y2]
[BLUE,x1,y1,x2,y2]
[RED,x1,y1,x2,y2]
]
Furthermore, because the model for identifying the position and the color of the lamp bead on the jump image of the LED lamp string can only output the coordinate position and the corresponding color of the image, and the address of the lamp bead cannot be output. We need to determine the address by calculating the shortest distance for each bead location of the picture.
The calculation steps are as follows:
and comparing the distance between each lamp bead of the first picture and each lamp bead of the rest pictures. Referring to fig. 3, because the predicted result of the taken picture to the server has a slight position error for each picture, the positions of the same lamp bead in different pictures need to be determined by comparing the distances;
selecting the color corresponding to the minimum distance and position of each picture;
after the color is obtained, the color and the position are arranged to form a matrix bead position matrix B. The address of the lamp bead can be determined by querying the matrix A.
Specifically, assume that matrix a has the following data:
A＝[
RED,RED,BLUE
RED,RED,RED,
GREEN,BLUE,RED
]
the data obtained by the IOU cross-over ratio are as follows:
B＝[
GREEN,BLUE,RED,x1,y1,x2,y2
RED,RED,BLUE,x1,y1,x2,y2
RED,RED,RED,x1,y1,x2,y2
]
now we have two matrices, matrix a and matrix B, the row number of each row of matrix a represents the address of the lamp bead. The data of 1-3 of the matrix B can be taken to search the data row of the matrix A, so that the address and the position of the lamp bead can be obtained.
The method for determining the positions of the LED lamp string beads comprises the steps of firstly establishing connection between a lamp string control APP and an LED lamp string, and sending a jump instruction to the LED lamp string through the lamp string control APP so as to change the color of each bead in the LED lamp string; after jumping, the color arrangement mode of each lamp bead is unique; after the color of the LED lamp string is changed, the lamp string control APP takes pictures of the LED lamp string at the same angle to obtain an LED lamp string jump image; and after the shot LED lamp string hopping image is the final hopping image of the LED lamp string, identifying the positions and colors of the lamp beads of all the LED lamp string hopping images, and determining the actual positions of the lamp beads in the LED lamp string according to the color arrangement and the address of each lamp bead. Compared with the prior art, the method can accurately determine the actual positions of the lamp beads in the LED lamp string which is randomly placed or arranged outdoors, thereby being convenient for realizing the change of patterns and colors of the LED lamp string without changing the current position of the LED lamp string and meeting the actual application requirements.
