The details will be described respectively below.

first embodiment

In this embodiment, description will be made from the perspective of the measuring device for the area area, and the measuring device for the area area may specifically be integrated in a terminal (such as a tablet computer, a mobile phone, etc.).

A method for measuring an area, comprising: acquiring an area to be measured; establishing a coordinate model based on a terminal infrared sensing method; determining an anchor point of the area to be measured under the coordinate model and coordinate information of the anchor point; The area of the region to be measured is measured according to the coordinate information and by a preset calculation formula.

Please refer to FIG. 1. FIG. 1 is a schematic flow chart of the method for measuring the area area provided by the first embodiment of the present invention. The specific process may include:

In step S101, a region to be measured is obtained.

In step S102, a coordinate model is established based on the terminal infrared sensing method.

In step S103, the positioning point of the area to be measured under the coordinate model and the coordinate information of the positioning point are determined.

Wherein, the steps S101 to S103 may specifically be:

Based on the terminal infrared sensing method, a two-dimensional coordinate model is established, and the horizontal axis and vertical axis are set.

For example, turn on the infrared device of the terminal (such as tablet computer, mobile phone, etc.), establish a two-dimensional coordinate model, and set the X axis and Y axis, and use infrared to project the area to be measured (such as houses, shops, etc.) In the two-dimensional coordinate model, positioning and calculation are carried out.

Further, the manner of determining the positioning point of the area to be measured under the coordinate model and the coordinate information of the positioning point can be specifically as follows:

(1) project the region to be measured into four quadrants under the coordinate model;

That is, project the area to be measured into four quadrants of the two-dimensional coordinate model;

(2) determining the corner point of the area to be measured as the anchor point of the area to be measured under the coordinate model;

(3) Determine corresponding coordinate information according to the positioning point and the position of the positioning point in each quadrant.

That is to say, in the four quadrants, the corner points of the area to be measured are respectively determined as the positioning points for measurement, and the position of each positioning point in each quadrant is recorded, so as to obtain the corresponding coordinate information.

In step S104, the area of the area to be measured is measured according to the coordinate information and by a preset calculation formula.

It can be understood that the area measurement according to the coordinate information can be specifically as follows:

a. Calculate the length and width of the area to be measured according to the coordinate information;

b. Measure the area of the region to be measured according to the length and width, and through a preset calculation formula.

Specifically, for example, calculate the length and width of the measurement area occupied by each quadrant according to the coordinate information; calculate the area of each part according to the length and width, and through the preset calculation formula; finally, add the area of each part , realizing the measurement of the area of the area to be measured.

Preferably, before performing the step of "measuring the area of the region to be measured according to the length and width, and through a preset calculation formula", it may also include:

Detect the shape type of the area to be measured in the corresponding quadrant, and determine the corresponding preset calculation formula according to the detection result.

For example, if the shape type is determined to be a rectangle, the calculation formula is the product of the length and width; if the shape type is determined to be a triangle, the calculation formula is half of the product of the length and width, and so on. For a regular shape, it can be split first, and each part can be calculated separately, which is not specifically limited here.

It can be seen from the above that the method for measuring the area area provided by this embodiment is based on the terminal infrared sensing method to establish a coordinate model, and then determine the positioning point and the coordinate information of the positioning point of the area to be measured under the coordinate model, and finally according to Coordinate information automatically measures the area of the area to be measured through the preset calculation formula, which improves the efficiency of measurement and the accuracy of measurement results compared to the method of area measurement based on manual work.

In step S201, the infrared sensing device of the mobile phone is turned on.

In step S202, the coordinate information of each corner position of the house to be measured is recorded.

Wherein, the steps S201 and S202 may specifically be:

First, turn on the infrared device of the mobile phone, build a model, set the X axis and Y axis, and project the house to be measured into the four quadrants of the coordinate model; as shown in Figure 2b, it is the projection of the house to be measured on the coordinate model hint.

Then, determine the corner point of the house to be measured as the anchor point of the house to be measured under the coordinate model, as shown in Figure 2b, the anchor points are six anchor points a-f, and record that each anchor point is in each quadrant coordinate information.

In step S203, according to the coordinate information, the area of the house to be measured is measured using a corresponding calculation formula.

For example, send the coordinate maps and coordinate information of these positioning points to the database of the mobile phone, and then the algorithm formula inside the mobile phone uses the coordinate information to calculate the length and width of the measured houses occupied in each quadrant, and then according to the length and width , and calculate the area of each part through the preset calculation formula, and realize the measurement of the area of the area to be measured by adding the areas of each part.

Further, in general, if the shape of the area in the quadrant is a regular shape, the area calculation formula can be: length x width = area, so as to calculate the size of the area; if the shape type is an irregular shape, you can first calculate the area It is split and each part is calculated separately.

For another example, if there is an oblique angle in the area in the quadrant, the area in the quadrant can be divided into triangles and rectangles for measurement, so that the area of each part can be calculated separately; if there is an arc in the area in the quadrant, for the arc edge , can adopt the way of taking more points, and use the circle area calculation formula S=ΠR2/2 to calculate the area size of the area in the quadrant, etc., so as to realize the measurement of the entire house area.

It can be understood that, for parts not described in detail in this embodiment, reference may be made to relevant content in the first embodiment, and details are not repeated here.

It can be seen from the above that the method for measuring the area area provided by this embodiment is based on the terminal infrared sensing method to establish a coordinate model, and then determine the positioning point and the coordinate information of the positioning point of the area to be measured under the coordinate model, and finally according to The coordinate information automatically measures the area of the area to be measured through the preset calculation formula, which improves the efficiency of the measurement and the accuracy of the measurement results compared to the method of area measurement based on manual work; further, the invention makes good use of the mobile phone The infrared function measures the size of the house by modeling, so that the area of the house can be measured at any time, especially when looking at some houses, it is easy to carry around, the operation is simple and easy to understand, and the area can be calculated quickly, which is conducive to direct evaluation of the house , the cost is greatly reduced.
