Description

Technical Field

[0001] The utility model belongs to the technical field of shooting systems, and particularly relates to an omnidirectional skin image shooting system. Background Art

[0002] Most of the existing human image acquisition systems are for range shooting of the face or body, with a wide acquisition range. Such systems have drawbacks such as insufficient light source and difficult positioning when shooting the torso and limbs, and it is also difficult to reposition the shooting position.

[0003] In the field of cosmetics testing, it is necessary to accurately capture images of the upper body, such as the face or upper arm, and to capture images of the skin again after applying cosmetics to confirm the effect of cosmetics on human skin. In order to improve the test efficiency, samples of skin in different areas of the person being tested will be taken at the same time during the test. Generally speaking, if only one set of shooting system is used for image capture, it is difficult to capture images again at the same shooting position after shooting a piece of skin. At this time, a shooting system is needed that can capture all-round images of the skin and ensure repeated shooting of the designated area after determining the shooting area. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an all-round skin image shooting system, which can accurately capture images of multiple tested skin areas at one time during cosmetic testing, while ensuring that the designated areas can be repeatedly photographed after the test.

[0006] Preferably, the support frame comprises two parallel and horizontally arranged first crossbeams, the two first crossbeams are connected by a second crossbeam, and the height of the first crossbeams is higher than the head of the person being measured.

[0007] Preferably, it also includes a control unit, which is electrically connected to the camera and the multi-axis slide module.

[0008] Preferably, a first slide rail is provided on the X-axis support arm, and first sliders matching the first slide rail are provided at both ends of the Y-axis support arm; a second slide rail is provided on the top of the Y-axis support arm, and a second slider matching the second slide rail is provided on one side of the Z-axis support arm; a third slide rail is provided on the surface of the Z-axis support arm, and the two-dimensional rotating gimbal is a YZ plane rotating platform, and a third slider matching the third slide rail is provided on one side of the platform.

[0010] Beneficial Effects

[0011] The utility model adopts a multi-axis platform module to drive the movement of the camera, and can collect images of multiple skins to be tested in one test. The positioning of the multi-axis platform module is achieved through a servo motor, which can solve the problem of positioning repeatability when taking images of various parts of the body. The multi-axis platform module surrounds the central accommodating space, so that the user does not need to move, reducing image deviation caused by posture changes.
