DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] like Figure 1 FIG. 1 is a flowchart of a rapid mapping method for interior design provided by an embodiment of the present invention, the method comprising: S100, configuring detection equipment and building a detection equipment local area network, wherein the detection equipment local area network includes a plurality of detection equipment, the detection equipment is a signal transmitting end and a signal receiving end, and the number of the signal transmitting ends is at least two groups.

[0019] In this step, a detection device is configured. The detection device can be a signal transmitting end and a signal receiving end. The signal transmitting end is used to transmit a detection signal. Specifically, it can be a UWB transmitting end, or an ultrasonic transmitting end or other radio wave transmitting end. The signal transmitting end can transmit a single-beam detection signal in any direction in the horizontal plane. The coverage angle of the detection signal can be 1 degree or less. The signal receiving end is used to receive the detection signal. The signal transmitting end and the signal receiving end are also connected by wireless communication or wired communication, and data can be transmitted between the two. After the connection is completed, a local area network of the detection device is obtained. The signal transmitting end can be fixed on the same bracket, so the distance between the two groups of signal transmitting ends is fixed, and the starting position of the signal transmitting end is set at the edge of the detection area.

[0020] S200, the signal receiving end sends a detection instruction to the signal transmitting end, and the signal transmitting end sends a directional signal in all directions until the signal receiving end detects the signals of all signal transmitting ends at the same time and records the transmission information.

[0021] In this step, a detection instruction is transmitted to the signal transmitting end through the signal receiving end. When the detection is performed, the signal transmitting end and the signal receiving end are kept in the same horizontal plane. The positions to be detected are all positions where the wall edges are located. Then the positions to be detected are the corner points in the surveying and mapping plan, such as the positive corners or negative corners of the wall. The detection time is recorded in the detection instruction. When the signal transmitting end receives the detection instruction, it starts to transmit the detection signal. The detection signal is sent in a direction. The signal transmitting end works synchronously, but the working frequencies of the signal transmitting ends are different. The signal receiving end can determine the source of the signal according to the frequency of the received signal. The signal transmitting end starts to send the detection signal from a preset position. After the transmission is completed, it rotates a preset angle in a preset direction according to a preset angle interval, such as rotating 1 degree counterclockwise, and transmits the detection signal again. Repeat this process until the signal receiving end detects the signal of the current signal transmitting end, records the signal transmission angle and signal transmission time of the current signal transmitting end, until the signal receiving end detects the signals of all signal transmitting ends, and records the transmission information.

[0022] S300, construct a two-dimensional coordinate system, mark the position of the signal transmitting end, calculate the position of the signal receiving end according to the transmitting information, obtain the detection point, repeat this process to obtain the detection point array.

[0023] In this step, a two-dimensional coordinate system is constructed, and a corresponding number of positions are randomly selected from the two-dimensional coordinate system as the positions of the signal transmitting ends according to the distances between the signal transmitting ends, and their coordinates are recorded. Corresponding detection rays are constructed in the two-dimensional coordinate system according to the signal transmitting directions recorded in the transmitting information. The starting point of the detection rays is the position of the signal transmitting end, and the intersection of multiple groups of detection rays is the position of the detection point. All edge lines in the detected area are detected to obtain multiple detection points to construct a detection point matrix.

[0024] S400, analyzing the detection points in the detection point matrix, identifying the wall formed by the detection points, and generating a surveying and mapping plan according to the location of the wall.

[0025] In this step, the detection points in the detection point matrix are analyzed. Specifically, the detection points can be connected in the order in which they are generated, so as to connect all the detection points. The position of the wall is determined based on the shape enclosed by the detection points. A surveying and mapping plan is generated based on the position of the wall, and different features are used to distinguish the walls based on their thickness.

[0026] like Figure 2As shown, as a preferred embodiment of the present invention, the signal receiving end transmits a detection instruction to the signal transmitting end, and the signal transmitting end transmits a directional signal in all directions until the signal receiving end simultaneously detects the signals of all signal transmitting ends, and the step of recording the transmission information specifically includes: S201, transmitting a detection instruction to all sides through a signal receiving end, receiving a signal through a signal transmitting end, and obtaining a detection instruction.

[0027] In this step, the signal receiving end transmits a detection instruction to the surroundings, and the detection instruction is transmitted to the signal transmitting end through wireless communication or wired communication. When the signal transmitting end receives the detection instruction, it indicates that the position of the signal receiving end has been fixed and detection can begin.

[0028] S202, transmitting a detection signal in a preset direction through the signal transmitting end. If no feedback information is received from the signal receiving end, deflecting in the preset direction and transmitting the detection signal again.

[0029] In this step, a detection signal is transmitted to a preset direction through the signal transmitting end, and the preset direction can be the north direction. When setting the signal transmitting end, the starting direction of the signal transmitting end is set to the north direction, so that all signal transmitting ends start to transmit the detection signal from the north direction. The coverage range of the detection signal is limited to a very narrow range, such as an angle range of 1 degree or less. Therefore, only when the signal transmitting end is facing the signal receiving end, the signal receiving end can receive the corresponding detection signal. If no feedback information is received from the signal receiving end within a preset time period, it is determined that the signal receiving end has failed to receive the detection signal. At this time, it can be deflected in a clockwise or counterclockwise direction, which is specifically set according to the needs. The deflection angle is a preset value, and then the detection signal is transmitted again to repeat this process.

[0030] S203, when the signal transmitting end receives the feedback information from the signal receiving end, the direction of the current signal transmission is recorded to obtain transmission information.

[0031] In this step, when the signal transmitting end receives the feedback information from the signal receiving end, the direction of the current signal transmission and the signal transmission time are recorded. Once the signal transmitting end receives the feedback information, it indicates that the detection signal of the current signal transmitting end is pointing to the signal receiving end. At this time, the transmission direction of the current detection signal (i.e., directional signal) is recorded. If there are two signal transmitting ends, there will be two sets of transmission information.

[0032] like Figure 3 As shown, as a preferred embodiment of the present invention, the steps of constructing a two-dimensional coordinate system, marking the position of the signal transmitting end, calculating the position of the signal receiving end according to the transmitting information, obtaining the detection point, repeating this process, and obtaining the detection dot matrix specifically include: S301, constructing a two-dimensional coordinate system, randomly selecting an initial position as the position of the signal transmitting end, fixing the distance between two groups of signal transmitting ends, and obtaining the coordinates of the signal transmitting end.

[0033] In this step, a two-dimensional coordinate system is constructed, such as Fig. 9 As shown, first randomly select a position as the position of a signal transmitter. For example, if the distance between two signal transmitters is 50 cm, the signal transmission starting direction of the signal transmitter is set to the due north direction. The two groups of signal transmitters are also set along the north-south direction. Based on this, the position of the other signal transmitter is determined and its coordinates are recorded.

[0034] S302, extracting the direction of signal transmission in the transmission information, constructing a detection ray, and generating a detection point in a two-dimensional coordinate system.

[0035] In this step, the direction of signal transmission in the transmission information is extracted. Each group of signal transmitting ends corresponds to a group of detection rays. The starting point of the detection ray is the location of the signal transmitting end. The transmission angle of the detection camera is the direction of signal transmission. The intersection of the detection rays is the location of the detection point.

[0036] S303, the position of the mobile signal receiving end is sent again, and the detection instruction is repeated, and this process is repeated until the surveying is completed, and multiple detection points are obtained in the two-dimensional coordinate system, and all the detection points together constitute a detection point matrix.

[0037] In this step, the position of the signal receiving end is moved. The signal receiving end is always located in the horizontal plane where the signal transmitting end is located, and the detection point where the signal receiving end is located is located on the edge line of the wall. Each time it moves to a new detection position, a detection is performed, and a detection point is obtained in the two-dimensional coordinate system until the detection is completed. All detection points together constitute a detection point matrix.

[0038] like Figure 4 As shown, as a preferred embodiment of the present invention, the step of analyzing the detection points in the detection point matrix, identifying the wall formed by the detection points, and generating a surveying and mapping plan according to the location of the wall specifically includes: S401, recording the generation order of each detection point in the detection point matrix, and connecting the detection points in order to obtain a detection pattern.

[0039] S402, identifying a rectangular area in the detection pattern, dividing it into an inner wall, and dividing the outermost line segment into an outer wall.

[0040] In this step, the generation order of each detection point in the detection point matrix is ​​recorded, and the detection points are connected according to the generation order, so as to connect all the detection points, connect the first detection point with the last detection point, and obtain a detection pattern. The detection pattern is identified to determine the wall contained therein. For example, whether it is a wall is determined based on the width and length of the pattern. The outermost circle of lines on the detection pattern is the external wall, that is, the boundary of the detection area, and the internal wall is the area enclosed by multiple detection points.

[0041] S403, marking different walls with different features to generate a surveying and mapping plan.

[0042] In this step, different walls are marked with different features, such as using pattern filling or color filling to distinguish the walls, so as to obtain a surveying and mapping plan. The user can make partial modifications to the surveying and mapping plan according to the actual plan.

[0043] In this embodiment, when the surveying area is larger than the preset value and the distance between the signal receiving end and the signal transmitting end reaches the preset value, the position of the signal transmitting end is moved and the already measured detection points are repeatedly measured, such as Fig. 9 As shown, if point A, point E and point B are the detection points that have been measured, then after moving the signal transmitter, point A is measured again, then point A and the new position of the signal transmitter (if the signal transmitter is defined as point C and point D) form a triangle, and the distance between AC and the distance between AD can be calculated. Similarly, the distances between BC, BD, EC and ED can be calculated. According to the three sets of distance values ​​AC, EC and BC, three circles can be constructed in the plane coordinate system, with centers A, E and B respectively, and radii AC, EC and BC respectively. The intersection of the three circles is the position of point C. Similarly, the position of point D can be determined to update the position of the signal transmitter.

[0044] like Figure 5 As shown, a rapid mapping system for interior design provided by an embodiment of the present invention includes: The device configuration module 100 is used to configure the detection device and build a detection device local area network. The detection device local area network includes multiple detection devices. The detection devices are signal transmitters and signal receivers. The number of signal transmitters is at least two groups.

[0045] In this system, the device configuration module 100 configures the detection device, and the detection device can be a signal transmitting end and a signal receiving end. The signal transmitting end is used to transmit the detection signal. Specifically, it can be a UWB transmitting end, or an ultrasonic transmitting end or other radio wave transmitting end. The signal transmitting end can transmit a single-beam detection signal in any direction in the horizontal plane, and the coverage angle of the detection signal can be 1 degree or less. The signal receiving end is used to receive the detection signal. The signal transmitting end and the signal receiving end are also connected by wireless communication or wired communication, and data can be transmitted between the two. After the connection is completed, a local area network of the detection device is obtained. The signal transmitting end can be fixed on the same bracket, so the distance between the two groups of signal transmitting ends is fixed, and the starting position of the signal transmitting end is set at the edge of the detection area.

[0046] The signal transceiver module 200 is used to transmit a detection instruction to the signal transmitting end through the signal receiving end, and the signal transmitting end transmits a directional signal in all directions until the signal receiving end detects the signals of all signal transmitting ends at the same time and records the transmission information.

[0047] In this system, the signal transceiver module 200 transmits a detection instruction to the signal transmitting end through the signal receiving end. When performing the detection, the signal transmitting end and the signal receiving end are kept in the same horizontal plane. The positions to be detected are all the positions where the wall edges are located. Then the positions to be detected are the corner points in the surveying and mapping plan, such as the positive corners or negative corners of the wall. The detection time is recorded in the detection instruction. When the signal transmitting end receives the detection instruction, it starts to transmit the detection signal. The detection signal is sent in a direction. The signal transmitting end works synchronously, but the working frequencies of the signal transmitting ends are different. The signal receiving end can determine the source of the signal according to the frequency of the received signal. The signal transmitting end starts to send the detection signal from a preset position. After the transmission is completed, it rotates a preset angle in a preset direction according to a preset angle interval, such as rotating 1 degree counterclockwise, and transmits the detection signal again. Repeat this process until the signal receiving end detects the signal of the current signal transmitting end, records the signal transmission angle and signal transmission time of the current signal transmitting end, until the signal receiving end detects the signals of all signal transmitting ends, and records the transmission information.

[0048] The detection dot matrix construction module 300 is used to construct a two-dimensional coordinate system, mark the position of the signal transmitting end, calculate the position of the signal receiving end according to the transmission information, obtain the detection point, and repeat this process to obtain the detection dot matrix.

[0049] In this system, the detection point matrix construction module 300 constructs a two-dimensional coordinate system, randomly selects a corresponding number of positions from the two-dimensional coordinate system as the positions of the signal transmitting ends according to the distance between the signal transmitting ends, records their coordinates, and constructs corresponding detection rays in the two-dimensional coordinate system according to the signal transmission direction recorded in the transmission information. The starting point of the detection ray is the position of the signal transmitting end, and the intersection of multiple groups of detection rays is the position of the detection point. All edge lines in the detected area are detected to obtain multiple detection points to construct a detection point matrix.

[0054] The detection control unit 202 is used to transmit a detection signal in a preset direction through a signal transmitting end. If no feedback information is received from a signal receiving end, the detection signal is deflected in a preset direction and transmitted again.

[0055] In this module, the detection control unit 202 transmits a detection signal to a preset direction through a signal transmitting end. The preset direction can be the north direction. When setting the signal transmitting end, the starting direction of the signal transmitting end is set to the north direction, so that all signal transmitting ends start to transmit detection signals from the north direction. The coverage range of the detection signal is limited to a very narrow range, such as an angle range of 1 degree or less. Therefore, only when the signal transmitting end is facing the signal receiving end, the signal receiving end can receive the corresponding detection signal. If no feedback information is received from the signal receiving end within a preset time period, it is determined that the signal receiving end has failed to receive the detection signal. At this time, it can be deflected in a clockwise or counterclockwise direction, which is specifically set according to the needs. The deflection angle is a preset value, and then the detection signal is transmitted again to repeat this process.
