Sampling area determination method and device, electronic equipment and storage medium

The invention provides a sampling area determination method and device, electronic equipment and a storage medium. The determination method is used for determining a sampling area for nucleic acid sampling in an oral cavity. The determination method comprises the following steps: acquiring image features of a first image; inputting the image features into a first model, and determining whether the first image needs illumination enhancement; under the condition of determining that the first image needs illumination enhancement, performing illumination enhancement on the first image, and determining a sampling area according to the first image after illumination enhancement; and when it is determined that the first image does not need illumination enhancement, a sampling area is determined according to the first image, and the first model represents a model constructed according to a re-parameterization algorithm. 本申请提出了一种采样区域的确定方法、装置、电子设备和存储介质。该确定方法用于确定口腔内进行核酸采样的采样区域，该确定方法包括：获取第一图像的图像特征；将图像特征输入至第一模型，确定第一图像是否需要
