[0044] In one possible embodiment, the lesion recognition process involved in the present application specifically includes the following contents: the lesion image to be identified is input into a trained lesion recognition model to perform lesion type identification and obtain a lesion type recognition result. The lesion recognition model is specifically a deep neural network model, and the lesion recognition model is obtained by pre-training an initial model with sample lesion images marked with corresponding lesion type recognition results.

[0045] Specifically, a neural network model is trained using a set of labeled sample lesion images, enabling it to learn the characteristic patterns of different lesion types. Lesion images to be identified are then fed into the trained model, which then outputs information such as whether the image contains a lesion and the type of lesion. After obtaining the recognition results, post-processing can be performed, such as removing misidentifications and merging similar lesions, to improve recognition accuracy and reliability.

[0046] In summary, the image processing module achieves effective processing and accurate identification of lesion images by performing preprocessing and lesion identification on the acquired lesion images.

[0047] In a possible implementation, the barrel 1 further includes: a power module 4, which is used to supply power to the lighting module, the image acquisition module, the image processing module, and the control module respectively.

[0048] Specifically, high-capacity lithium batteries can be used as the power source, combined with intelligent power management to monitor battery status in real time, optimize energy distribution and usage strategies, and reduce ineffective power consumption. This can extend the continuous use time of the device, improve the user experience, and thus reduce charging frequency and lower usage costs.

[0049] In a possible embodiment, the flashlight also includes a power switch 5, which is arranged on the side wall of the barrel 1 and is used to turn on and off the power module 4; the flashlight also includes an image acquisition switch 6, which is arranged on the side wall of the barrel 1 and is used to control the acquisition submodule 31 to perform image acquisition.

[0050] The barrel 12 is embedded with a display screen 7, which is used to display the lesion image, the battery level of the power module 4, and the type of light source. The display screen 7 is electrically connected to the power module 4, the control module, and the lighting module.

[0051] This application can use integrated circuit design and manufacturing processes to highly integrate multiple functional units such as the image acquisition module, image processing module, control module, and data transmission module on a single microchip.
