Integrate a 3D scanner in a semi-enclosed device to scan a woman's chest. Do the assessment of symmetry and other data.

1. The scanning range should not be less than 700mm*400mm
2. The scanning accuracy is within 2mm.
3. The total scan time should not be higher than 5 seconds.
4. The distance between the scanner and the target is not more than 500mm.
5. The scanner can be installed in the device with the size as shown in the figure below and work normally
6. The equipment scanning success rate is 100% (may vary according to different site environments, but it does not affect the measurement)

Three, development requirements
1. Our platform directly starts the scanner custom software software through the software function. After the software is opened, the scanning operation is performed directly, without the need to click additional buttons.
2. After the scanning is completed, the scanning software directly displays the scanning results in the interface. Users can click on any position of the 3D model generated in the scanner software to punctuate the point positions as shown in the figure below, and the punctuation order is carried out according to the preset order. .
3. After the punctuation, the user clicks OK, and the scanner saves the distance array, front view and 3D image of all the punctuation points calibrated by the user in sequence to the specified directory. (The punctuation data is saved in text or xml format, and the next punctuation data will overwrite the last one. , pictures are saved in picture format, and 3D images are saved in 3D image format)
4. After the punctuation is completed, the user clicks the confirm button in the scanner to save the data, and the confirm transfer data button in the scanner software can assign a shortcut key, and close the scanner software after the successful data transfer.

4. Sample pictures

The resulting image is centered

5. Point location (the following data size has no practical significance)

• 

• S-N. The distance between the suprasternal concave notch and the nipple: 35cm

  N-F. Distance from nipple to inframammary fold: 35cm

  BW. Breast base width: 35cm

  BH. Breast height: 35cm

  ID. Breast spacing: 35cm

Six, specific solutions

Scanner selection: two sets of infrared sensors are used to collect data, and the relative positions of the two sensors can be calibrated and scanned to obtain data within 1 second;
1. Software development process: directly start the scanning software, the interface will be redeveloped, simple, only the scanning and measurement functions are left; similar to the following interface:

2. Measurement: After scanning, the scanned data is automatically displayed directly. The user can directly mark the user-defined point on the 3D data, mark the automatic measurement, and write the data to the specified directory;

3. Data storage: In the specified directory, save three files: STL (scanned three-dimensional data), JPG (three-dimensional data screenshot), txt (measured data).

Seven, equipment expected renderings
1. CAD dimension drawing

2. 3D map
