The present application relates to the technical field of infrared image processing, and provides an end-side lightweight infrared image denoising method and device and electronic equipment.The method comprises the following steps: acquiring an infrared image with noise to be processed; inputting the infrared image with noise into a target lightweight network trained in advance to output a predicted denoising image; the target lightweight network is obtained by optimization in a training stage based on a joint loss function; the joint loss function at least comprises a pixel-level reconstruction loss, a gradient domain sparse regularization loss and a vertical direction smoothing constraint loss; the gradient domain sparse regularization loss constrains a residual image between a reference image and the predicted denoising image, so that the residual image remains sparse in the gradient domain; the vertical direction smoothing constraint loss is used to calculate a difference value of adjacent pixels in the vertical direction of the predicted denoising image, and the difference value is punished to suppress horizontal stripe noise in the infrared image.The present application solves the contradiction between limited computing power and high-fidelity denoising.
