(1) compared with other breast measuring systems at present, the utility model does not need a measuring tool specially used for and a complex adjusting device, and is simple and quick to use.

(2) The utility model discloses a notebook computer and Kinect three-dimensional camera, it is convenient simple. The total weight is less than 4 kg, the volume is small, the weight is light, and the carrying is convenient. The device can be used for measuring in any indoor space of a hospital, measuring at any time, analyzing quickly and outputting results quickly.

(3) The digital rapid measurement can accurately obtain the shape and the volume of the breast. The volume of the prosthesis or the volume of the liquid injection of the dilator, which can be selected by a doctor, can be accurately guided, the medical cost can be obviously reduced, the operation preparation time can be reduced, and the operation precision can be improved.

(4) It takes a short time. The utility model discloses can obtain three-dimensional structure fast after the scanning, obtain three-dimensional grid structure in being less than 1 minute, information such as the breast volume of patient, surface area are obtained in the analysis in being less than 30 minutes.

(5) The price is low. The utility model discloses regard as three-dimensional scanning camera with Kinect, other laser three-dimensional scanner cheaply are compared very much to the price. The cost of such a system is far less than three-dimensional scanning systems currently found on the market.

(6) The volume and the surface area can be analyzed, and the errors before and after operation can be analyzed. The volume and the surface area of the point cloud model obtained from scanning can be rapidly calculated. The actual effect and error of the operation can be analyzed through model fitting before and after the operation.

(7) The utility model discloses have good expansibility, can combine together with augmented reality glasses, realize real-time three-dimensional model augmented reality and show, provide the guidance to the medical procedure.

Detailed Description

The present invention will be further described in with reference to the following drawings and detailed description.

As shown in fig. 1, the utility model discloses utilize the scanning function of Kinect scanner or Kinect three-dimensional camera, utilize the frame that the three-dimensional object of Kinect scans and the model structure (Kinect Fusion Explorer-D2D) to scan patient's breast region, obtain patient's three-dimensional appearance grid structure. The grid file obtained by scanning is processed by three-dimensional analysis software at a computer end, redundant structures are cut and deleted, the grid structure is optimized, irregular shapes are removed, holes are filled, the appearance of the chest wall and the breasts is constructed, and the volume and the surface area of the breasts are calculated. For the finally obtained breast structure, the analysis-calculation volume is selected to obtain the breast volume. The breast surface area can be obtained by selecting an analysis-calculation surface area function. Through the rapid digital measurement, the breast volume can be accurately measured and directly used for guiding the selection of the prosthesis volume in the breast reconstruction operation, so that the cost is greatly saved (the prosthesis material is very expensive). And the actual effect and error of the breast reconstruction operation are analyzed through the comparison of the digital models before and after the operation.

The method comprises the steps of generating a three-dimensional analysis software, and cutting a plurality of non-interesting regions by using the three-dimensional analysis software, wherein the three-dimensional analysis software is used for generating scanning original data of a large range of original data, the data comprises a patient and a standing or lying environment of the patient, the data information is imported into the three-dimensional analysis software, step is used for cutting redundant structures, namely, the three-dimensional analysis software is used for selecting and cutting non-interesting regions, removing peripheral environment data, and keeping interested breasts and surrounding regions of the patient.

Fig. 2 is a schematic diagram of the design structure of breast shape measuring devices based on the Kinect, in which 1 represents a notebook computer for displaying and processing three-dimensional model information, 2 represents a Kinect scanner for scanning the body shape of a patient, the Kinect is connected with the notebook computer, and 3 represents the patient, the patient can be standing or lying, and both of them can be used for the Kinect to scan to obtain a three-dimensional grid structure.

The Kinect is provided with three cameras, color RGB cameras are used for collecting color images, the two depth collecting cameras are mainly used for emitting infrared light and receiving 3D structured light, and the depth information of a three-dimensional object can be obtained through the two cameras.

For the patient whose breast volume is to be measured, there are two methods for measurement, are stand measurement and are lying measurement, no matter whether standing or lying, the usage of the measurement system is , step , the system is opened, the Kinect fusion Explorer-D2D scanning module is opened, the second step is to place the Kinect at a distance of 30-100 cm from the patient, click the operation button, wait for about 30s, observe the created grid, move the Kinect appropriately to the area where the grid creation is not completed, click the creation grid button to retain the three-dimensional grid data, the third step is to introduce the three-dimensional grid data into the modeling software, cut and delete the area, optimize the grid structure, fill in, and calculate the desired irregular data, analyze and calculate the breast volume as 361635mm³And the surface area of the breast is 33136mm²。

For comparing the operation effect, the basic steps are the same as , but the breast data of the same posture of the patient before and after the operation is required to be scanned, the grid information is imported into the three-dimensional modeling software for fitting, and the operation effect can be accurately analyzed by analyzing the data difference of the two models, as shown in fig. 3, a gap exists between the new scanning image (point layer) and the old scanning image (trunk), the gap is almost the height of the nipple, and the gap can visually reflect the actual effect and the error.
