Abstract
Description
Technical Field
[0001] This invention relates to the field of medical aesthetics, and in particular to a portable binocular stereo vision 3D imaging device based on a single camera. Background Technology
[0002] As people's quality of life improves, the pursuit of beauty becomes more and more common, which drives the continuous development of the medical aesthetics market.
[0003] Before undergoing any cosmetic procedure, thorough testing and evaluation are crucial, and a precise 3D model imaging device is extremely helpful for both doctors and consultants. With the development of the cosmetic industry, emerging procedures are no longer limited to the face and head but also include other body parts such as the arms and thighs. However, existing domestic products are primarily designed for the face. Since the face differs in size from other body parts, the required shooting distances also differ, and current products are not compatible with various shooting distances, thus failing to capture images of any part of the body. Furthermore, current single-camera binocular imaging devices often have lighting components that illuminate at angles inconsistent with the actual shooting angle, resulting in uneven brightness and causing shadows or overexposure.
[0004] Therefore, there is an urgent need for a portable binocular stereo vision 3D imaging device based on a single camera that can quickly adjust the distance between the device and the subject and make the fill light angle consistent with the shooting angle. Summary of the Invention
[0005] The purpose of this invention is to provide a portable binocular stereo vision 3D imaging device based on a single camera, which aims to solve the technical problem of inconsistent shooting angle and supplementary lighting angle in existing single-camera binocular imaging devices. At the same time, it can also conveniently determine the optimal shooting distance for different shooting objects.

[0011] The two laser emitters on the front of the device in this scheme are used to determine the most suitable shooting distance. During positioning, the two laser emitters obliquely shoot lasers at a certain angle to the center line in front. Move the device to move it away from or closer to the subject. When the two laser spots falling on the subject coincide, it is the optimal shooting distance.
[0012] The two laser emitters in this solution have multiple different angle settings, allowing for different shooting distances to suit different subjects.

[0017] The supplementary lighting assembly includes: a third optical path group, a fourth optical path group, a supplementary lighting placement window, and a supplementary lighting unit; the third and fourth optical path groups are symmetrical about the centerline of the supplementary lighting assembly; wherein,
[0018] The third optical path group includes: a fifth reflector and a seventh reflector through which the light emitted by the fill light passes in sequence; the light emitted by the fill light is reflected onto the subject by the third optical path group;
[0019] The fourth optical path group includes: a sixth reflector and an eighth reflector through which the light emitted by the fill light passes in sequence; the light emitted by the fill light is reflected onto the subject by the fourth optical path group.
