[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] In the process of determining the house type in the related art, the process is complicated and inefficient. Usually, manual measurement is performed with a tape measure or a laser rangefinder, which requires running around in the room and is slow. Moreover, the tape measure is inconvenient and prone to errors when measuring long distances or high roofs; handheld laser rangefinders are difficult to measure the dimensions of certain structures, such as columns, beams, and doors; surveyors need to hand-draw a rough floor plan on site first, and then measure and mark the data, which requires high capabilities of surveyors; floor plans cannot be generated on site, and need to be redrawn on the computer after returning, and the on-site sketch and computer-drawn floor plans are repeated twice, which is inefficient; since the complete floor plan is not generated on site, some data may be missed, and the surveyors may supplement the data based on memory when drawing, resulting in inaccurate floor plans; designers often need to combine on-site photos to recall the details of the situation on site when designing floor plans. Photos and floor plans are divided into different files, which is inconvenient to view, and it is difficult to match the location of photos and floor plans; in addition, taking a few single photos on site may not be comprehensive, and some areas may be missed.

[0060] In order to solve the problems in the related art, the present invention proposes a method for determining a house type.

[0061] The following is a further explanation of the housing type determination method provided by the present invention with reference to specific embodiments in conjunction with the accompanying drawings, and the embodiments do not constitute a limitation on the embodiments of the present invention.

[0062] Figure 1 The following is a flow chart of an embodiment of a method for determining a house type provided by an embodiment of the present invention. Figure 1 As shown, a method for determining a house type provided by an embodiment of the present invention is applied to an electronic device and may include the following steps:

[0063] Step 101 , obtaining a first image, wherein the first image is a panoramic image and includes all structural elements of a scene to be measured, and the scene to be measured is a physical space of a house.

[0064] In an embodiment of the present invention, a panoramic camera can be used to capture a panoramic image of the scene to be tested (i.e., the physical space of the house to be tested) to obtain a first image. The panoramic camera can be connected to an electronic device (e.g., a computer) to transmit the first image to the electronic device so that the electronic device acquires the first image.

[0065] The physical space of a house may include structures composed of walls, windows, doors, stairs, floors, roofs, etc. In the embodiment of the present invention, the above-mentioned structures of the house are defined as structural elements. In order to obtain enough structural elements and truly restore the scene of the house, a panoramic camera is used in the embodiment of the present invention to collect images of the house / scene to be tested.

[0066] Step 102: determine a target acquisition point for each structural element, and the target acquisition point is used to draw the scene to be tested.

[0067] In some embodiments, the structural type of all structural elements in the first image and the shape and size data of each structural element can be identified by a preset recognition algorithm, and then the target acquisition point of each structural element is determined according to the structural type and shape and size data of each structural element. Exemplarily, the structural elements in the first image, such as walls, roofs, floors, doors, etc., are identified by an AI (Artificial Intelligence) algorithm model, and then the acquisition point of each structure to be measured is identified according to the identified structural type and shape and size.

[0068] In an embodiment of the present invention, the principle for selecting the target collection points is as follows: by measuring the spatial coordinate data of the target collection points, the corresponding structural elements can be generated on the floor plan; the preset recognition algorithm can be a recognition model obtained through machine learning training, and the training process and method can refer to the prior art. For the sake of brevity, the present invention will not be repeated here.

[0069] Step 103: measuring the structural data of the target acquisition point.

[0070] The structural data may be, for example, the spatial position coordinate data of any structural element.

[0071] In this example, since there are many structural elements, in order to avoid missing a structural element and complete the measurement and data collection of all structural elements, the total number and relative position of the target collection points can be determined first, and then the spatial position coordinate data of each target collection point can be collected in sequence according to the total number and relative position, so as to obtain the structural data of the target collection points of all structural elements. Exemplarily, all target collection point marks can be displayed on the first image, wherein the target collection points include the data of all structural elements such as roof height, wall, door, window, beam, column, water and electricity required for drawing the floor plan in the room to be measured, and the measurement guide of the pre-set laser rangefinder is formed through these target collection points.

[0072] Furthermore, the measurement angle of the pre-set laser rangefinder can be adjusted according to the relative position of the target collection point to collect the spatial position coordinate data of the corresponding target collection point, and determine whether the spatial position coordinate data of all target collection points have been collected according to the total number of target collection points. For example, there are a total of 10 target collection points, each target collection point is digitally marked, and the relative position of the target collection point is set. The collection angle of the laser rangefinder is adjusted according to the relative position, so as to guide the laser rangefinder to collect data for all target collection points in turn. The laser rangefinder in the embodiment of the present invention is a laser rangefinder with a function of measuring spatial coordinates.

[0073] In some embodiments, in order to improve the accuracy and scene adaptability of the laser rangefinder,

[0074] The pre-set laser rangefinder is measured and calibrated, wherein the measurement calibration includes the origin angle calibration and the panoramic view angle calibration. Exemplarily, after the laser rangefinder is calibrated, you can click to measure at the origin position, and then click at the same position on the panoramic view (first image) displayed on the screen to calibrate the laser ruler angle position and the panoramic view display angle to be consistent, and then perform data measurement: rotate the laser rangefinder, and the panoramic view displayed will rotate synchronously at the same time. According to the instructions marked on the panoramic view (first image), the laser points to the collection point position indicated by the panoramic view, and the spatial position coordinate data of the collection point is measured. According to the instructions, rotate one circle (or the number of collections is greater than or equal to the number of target collection points), that is, the spatial position coordinate data of each collection point to be measured is measured in sequence.

[0075] In order to facilitate the timeliness of data processing and data storage, in an embodiment of the present invention, the spatial position coordinates of each target collection point, such as (x, y, z), can be transmitted back in real time.

[0076] Step 104, generating a second image of the scene to be tested according to the target collection point and the structural data corresponding to each target collection point, wherein the second image is a floor plan of a house, and includes a three-dimensional floor plan and a plane floor plan.

[0077] In some embodiments, a three-dimensional floor plan of a house corresponding to the scene to be tested can be calculated and drawn based on the spatial position coordinate data and the structural type corresponding to the target acquisition point, and a flat floor plan corresponding to the scene to be tested can be calculated and drawn based on the spatial position coordinate data and the structural type corresponding to the target acquisition point.

[0078] Step 105, performing image rendering on the three-dimensional floor plan in combination with the first image to obtain a third image.

[0079] The third image is a panoramic three-dimensional floor plan.

[0080] Generally speaking, after all the target collection points in the house are measured, the size, coordinate position, etc. of each structural element are calculated according to the structural type of each structural element to which the target collection point belongs and the measured spatial position coordinate data, thereby generating a three-dimensional floor plan and a plane floor plan of the house. Furthermore, the photographed panoramic image (first image) is re-mapped onto the three-dimensional floor plan generated by the measurement to generate a three-dimensional floor plan with a panoramic image.

[0081] It is understandable that if the house has multiple spaces, move to the next room for measurement, repeat the above steps, complete the measurement of all rooms, and use a unified coordinate system to stitch all the measured room layouts into a complete floor plan. If two adjacent rooms share a wall, the distance between the two walls of the two adjacent rooms is calculated based on the coordinate information as the wall thickness. Other walls are the system default wall thickness.

[0082] In the embodiment of the present invention, a manual modification operation is provided, and the designer can manually input the data to be modified. For example, after the floor plan is generated, the wall thickness data can be manually modified.

[0083] In other embodiments, a floor plan saving function is provided for saving floor plans. Floor plans can be exported into multiple formats and can be saved locally or uploaded to the cloud. The saved floor plans can be directly opened with design software to design decoration plans, which facilitates the use and search of floor plans in the future.

[0084] In addition, the embodiment of the present invention also provides for adding scene information, so that the basic information of the scene to be measured can be associated with the later generated floor plan and / or the relevant data of the measured structural elements, etc., to facilitate data search and tracing. Exemplarily, before starting the measurement, a measurement plan is established, and the basic information of the measured house is entered, such as the address, community, house number, customer name, contact information, room type, and other information of the house.

[0085] The technical solution provided by the embodiment of the present invention uses imaging technology and measurement technology to measure the physical space of a house. The measurement accuracy error is small, the operation is simple, and the floor plan can be automatically generated according to the measured structure and structural data, with high efficiency. In addition, by using the laser rangefinder method, the spatial three-dimensional coordinates of all key points in the house are accurately and comprehensively measured to construct the house type. All walls, beams, columns, doors and windows, water and electricity and other structures required for the floor plan can be accurately measured to form a complete floor plan. It is only necessary to fix a certain position in the house (for example, the center of the house), rotate the rangefinder, and measure a few points. All visible positions can be measured, and all required data can be quickly obtained without running around. Use recognition algorithms (such as AI visual recognition technology) to mark collection points (target collection points), and the measurement points (that is, the spatial position coordinate data of the target collection points) to calculate the rules for the structural dimensions of the house are preset in the algorithm, and the house measurement operation When measuring, one only needs to refer to the points marked on the panoramic photo for guidance, and the person measuring does not need to have an in-depth understanding of the measurement rules of the house structure. The threshold for personnel requirements is low, the operation is simple, and it is suitable for all kinds of people to use and can be widely promoted. The measurement data can directly generate a three-dimensional house type without manual drawing. The generated house type can be used directly, eliminating the workload of drawing the house type in the original house measurement process. The house type is generated on-site and can be seen intuitively, and the on-site comparison can be ensured to ensure that the house type measurement is accurate and no details are missed. The panoramic map is attached to the generated house type, and the house type is rendered to directly restore the appearance of the site, so that all the details of the site can be directly seen when the house type design is used later.

[0086] The embodiment of the present invention also provides an apparatus embodiment corresponding to the aforementioned method embodiment.

Moreover, it is only necessary to rotate the rangefinder and measure a few points in a fixed position in the house (for example, the center of the house).
