Personal skin scanner system
A personal skin lesion scanner system that can facilitate early detection of changes in the appearance of a user's skin is described. The system includes a handheld device for home use, to record images of a user's skin, and software for analyzing the images. The system can automatically detect changes in the user's skin, such as changes in the size, shape, or color of a skin lesion, and alert the user if any changes are detected.
1. A handheld scanner system comprising:
a handheld scanner device comprising:
a skin contact surface;
a primary camera spaced a distance apart from the skin contact surface, such that when the skin contact surface is contacted to a user's skin, the primary camera records a close up image of a desired area of the user's skin; and
an illumination source spaced a distance apart from the skin contact surface, such that when the skin contact surface is contacted to a user's skin the illumination source can illuminate the desired area of the user's skin; and
a computer system operably connected to the handheld scanner device via a data connection and provided with computer-readable instructions configured to cause the computer system to record and store a first plurality of images of one or more desired areas of the user's skin at an earlier time; and to cause the system to record and store a second plurality of images of the one or more desired areas of the user's skin at a later time, create a skin map based on second plurality of images, and while the skin map is being created, generating a 3D body model,
wherein the computer-readable instructions are further configured to cause the system to use a secondary camera and a SLAM algorithm to locate a mark on the user's skin.
2. The system of claim 1 , wherein the computer-readable instructions are further configured to cause the system to compare the first plurality of images and the second plurality of images of the one or more desired areas of the user's skin.
3. The system of claim 1 , wherein the computer-readable instructions are further configured to cause the system to detect changes in each of the one or more desired areas of the user's skin based on a comparison.
4. The system of claim 1 , wherein the computer-readable instructions are further configured to cause the system to locate a mark or lesion on the user's skin.
5. The system of claim 1 , the computer-readable instructions are further configured to cause the system to record and store the first plurality of images and second plurality of images as overlapping areas of the user's skin.
6. The system of claim 1 , wherein the computer-readable instructions are further configured to cause the system to create a mosaic image of the user's skin from the first plurality of images and second plurality of images as overlapping areas of the user's skin.
7. The system of claim 1 , wherein the primary camera records a second close up image of the desired area of the user's skin as one of the first plurality of images from a different perspective.
8. The system of claim 7 , wherein computer-readable instructions are configured to cause the system to construct a 3D image based on the first and second plurality of images of the desired area of the user's skin.
9. The system of claim 1 , wherein the data connection is a wireless data connection.
10. The system of claim 1 , wherein the skin contact surface includes one or more rollers configured to measure a direction and a distance traveled over a user's skin.
11. The system of claim 1 , wherein the illumination source includes one or more LEDs.
12. A method of detecting changes in a person's skin comprising:
contacting a skin contact surface of a handheld scanner device to a user's skin;
recording and storing a first plurality of images of one or more desired areas of the user's skin at an earlier time from the handheld scanner device;
creating a first skin map with the first plurality of images;
recording and storing a second plurality of images with a secondary camera of the one or more desired areas of the user's skin at a later time from the handheld scanner device;
creating a second skin map with the second plurality of images;
while the second skin map is being created, generating a 3D body model;
comparing the first plurality and second plurality of images of the one or more desired areas of the user's skin;
detecting changes in each of the one or more desired areas of the user's skin based on the comparison of the first plurality and second plurality of images;
identifying a location of the first and the second plurality of images in the 3D body model; and
alerting the user if any changes are detected and
recording an image of a part of the user's body, the image acquired from the secondary camera, and using the image of the part of the user's body and a SLAM algorithm to locate a mark on the user's skin.
13. The method of claim 12 , wherein the handheld scanner device includes:
a primary camera spaced a distance apart from the skin contact surface, such that when the skin contact surface is contacted to a user's skin, the primary camera can record a close up image of a desired area of the user's skin; and
an illumination source spaced a distance apart from the skin contact surface, such that when the skin contact surface is contacted to a user's skin the illumination source can illuminate the desired area of the user's skin;
wherein the handheld scanner device operably connects to a computer system provided with computer-readable instructions via a data connection.
14. The method of claim 13 , further comprising recording a second close up image of the desired area of the user's skin from a different perspective, and constructing a 3D image based on the first and second plurality of images of the desired area of the user's skin.
15. The method of claim 12 , wherein recording and storing a first or second plurality of images includes moving the handheld scanner device over the user's skin while the skin contact surface remains in contact with the user's skin.
16. The method of claim 12 , further comprising locating a mark or lesion on the user's skin based on the first or second plurality of images.
17. The method of claim 12 , wherein recording and storing a first plurality of images of one or more desired areas of the user's skin includes recording and storing images of overlapping areas of the user's skin.
18. The method of claim 12 , further comprising creating a mosaic image of the user's skin from images of overlapping areas of the user's skin.
19. The method of claim 12 , wherein the skin contact surface includes one or more rollers configured to measure a direction and a distance traveled over a user's skin and further comprising measuring a direction and a distance traveled by the handheld scanner device over the user's skin.
