Embodiment 1
[0054] see figure 1 , this embodiment provides a memory assistance method based on face recognition technology. Preliminary work is required before face recognition is performed, a suitable development platform is built, and a face database and a voice database are constructed based on this. Specifically, in this implementation, it is first necessary to determine the hardware device to which this embodiment is applied, and select a suitable visual sensor. Since this embodiment needs to be applied to build small, wearable devices, the visual sensor also needs to be small, light and Low cost feature. So a low-cost, powerful Open MV camera is used. With the STM32F427CPU as the core, the OV7725 camera chip is integrated, and the core machine vision algorithm is efficiently implemented through software on a small hardware module. In addition, a Python programming interface will be opened on the machine vision module, which is conducive to the secondary development of developers. ...
Embodiment 2
[0074] see figure 2 , this embodiment provides a face recognition technology-based memory assistance device based on Embodiment 1, and the device adopts the face recognition technology-based memory assistance method as required in any one of Embodiment 1.
[0075] see image 3 , in this embodiment, a memory aid device based on face recognition technology, including: an image acquisition module, an image processing module and a voice module.
[0076] The image acquisition module is used to acquire the face images of the entry personnel and the personnel to be tested.
[0077] The image processing module is used to compare the face image with the images in the pre-stored face database to obtain the corresponding label information of the person to be tested in the face database.
[0078] Based on the face image, the LBP algorithm feature extraction is carried out to obtain the gray feature map of the face image. According to the comparison between the grayscale feature map an...
Embodiment 3
[0082] A computer device, comprising a memory and a processor, wherein computer-readable instructions are stored in the memory, and when the computer-readable instructions are executed by the processor, the processor executes the memory based on face recognition technology as in any one of Embodiment 1 helper method.
