Description

Technical Field

[0001] The utility model relates to the technical field of face recognition and acquisition, in particular to an acquisition device for face recognition modeling. Background Art

[0002] Face recognition is a biometric technology that identifies people based on their facial features. It uses a camera or webcam to capture images or video streams containing faces, automatically detects and tracks faces in the images, and then performs a series of face-related techniques on the detected faces.

[0003] However, existing facial recognition modeling acquisition equipment is usually set at a fixed angle to capture facial images. During facial acquisition, since the face is three-dimensional, only capturing facial images at a fixed angle makes the captured images unfavorable for three-dimensional modeling. Utility Model Content

[0005] According to the utility model, a collection device for face recognition modeling includes a device body, an installation cavity is provided inside the device body, a through opening through the installation cavity is formed on the device body, an arc-shaped slide rail is formed on the bottom wall of the installation cavity, a drive component is slidably provided on the slide rail, a camera for face image collection that cooperates with the through opening is provided on the drive component, and the drive component is used to drive the camera to slide along the slide rail.

[0006] Preferably, the driving assembly includes a slider slidably arranged on the slide rail, a mounting plate for mounting a camera is detachably provided on the top of the slider, a motor is provided on the mounting plate, a rotating shaft is provided at the output end of the motor passing through the mounting plate, and a gear is interference fit on the rotating shaft; a groove with the same curvature as the slide rail is formed on the bottom wall of the mounting cavity, and a tooth segment meshing with the gear is formed on the side wall of the groove.

[0008] Preferably, a cavity is formed at a position corresponding to the device body and the through-port, the through-port is arranged to have the same curvature as the slide rail, and a partition for sealing the cavity is provided at the cavity.

[0009] The above structure provides a buffer space for the camera when a collision occurs. At the same time, the setting of the partition helps to reduce the impact of external environmental factors such as light and temperature on the camera acquisition process, thereby improving the quality of the acquired image.

[0010] Preferably, the partition is made of transparent glass, thereby better ensuring that the camera can capture clear images.

[0011] Preferably, a through slot is formed on the top wall of the device body and is communicated with the installation cavity, and a cover is detachably provided in the through slot, so that the camera and the drive assembly in the installation cavity can be maintained preferably.

[0012] Preferably, a support portion is formed on the bottom wall of the mounting cavity and is located between the groove and the slide rail and is used to support the mounting plate. Rollers that cooperate with the mounting plate are formed on the bottom walls corresponding to the mounting plate and the support portion.

[0013] Through the above structure, the provision of the support portion increases the strength of the bottom wall of the installation cavity, providing a stable support platform for the installation plate.

[0014] The cooperation between the roller and the support portion reduces friction and vibration of the mounting plate during movement or positioning, and improves the stability of the mounting plate during sliding.

Compared with fixed-angle acquisition, multi-angle acquisition can capture the three-dimensional features of the face more comprehensively, which is conducive to improving the accuracy of three-dimensional face modeling and improving the accuracy of face recognition.
