Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a support device for measuring facial movements. Background Art

[0002] When measuring facial movements, a camera is usually used to capture the movements of the face of the person being tested to obtain a facial image of the person being tested. For example, in medical clinical practice, a camera is needed to capture high-definition facial images of patients with facial paralysis. It is necessary to capture images from multiple angles and then synthesize stereo images, so as to measure and analyze the facial movements of patients with facial paralysis as accurately as possible, and to evaluate the facial nerve function of patients with facial paralysis. When a camera is used to capture the facial movements of the person being tested, a supporting device such as a tripod is needed to fix the camera to avoid camera shaking during the shooting process. However, existing supporting devices such as tripods are still not stable enough and cannot meet the needs of practical applications. Existing supporting devices such as tripods can only be used to install and fix one camera, and cannot install and fix multiple cameras at the same time. However, when it is necessary to capture the facial movements of the person being tested from different angles, more than two cameras need to be used, so existing supporting devices cannot meet the needs of practical applications.

[0003] In addition, in order to obtain a high-definition facial image, when using a camera to shoot the facial movements of the subject, a background light needs to be used to illuminate the face of the subject to improve the lighting effect. In this case, the background light used for lighting also needs to be installed and fixed in front of the subject using a supporting device. Existing camera supporting devices such as tripods are not suitable for installing fixed background lights, and existing supporting devices specifically used for installing fixed lighting lamps are also not suitable for use in this scenario.

[0004] In summary, the prior art still lacks a supporting device specifically used for measuring facial movements, which can install and fix more than two cameras and more than two background lights.

[0005] In view of the above problems, how to provide a supporting device specifically for measuring facial movements, which can install and fix more than two cameras and more than two background lights, has become a technical problem that needs to be urgently solved by technical personnel in this field.
