The invention provides a depth image filtering method and device which are applied to the field of image processing, and the method comprises the steps: obtaining a depth image collected by a depth camera, and obtaining a target infrared intensity image corresponding to the depth image; and filtering the depth image based on the target infrared intensity image. According to the scheme, when the depth image is filtered, the target infrared intensity image is considered to be used for assisting, so that invalid pixels in the depth image can be filtered out and noise pixels in the depth image can be smoothed by fully utilizing the target infrared intensity image, and the quality of the depth image obtained by adopting the method is relatively high. 本申请提供一种深度图像的滤波方法及装置，应用于图像处理领域，其中，深度图像的滤波方法包括：获取深度相机采集的深度图像以及获取与深度图像对应的目标红外强度图像；基于目标红外强度图像对深度图像进行滤波。在上述方案中，在对深度图像进行滤波时，考虑利用目标红外强度图像进行辅助，从而可以充分利用目标红外强度图像滤除深度图像中的无效像素，平滑深度图像中的噪声像素，以使采用上述方式滤波得到的深度图像的质量较高。
