Embodiment Construction

[0023] refer to figure 1 , the present invention proposes a method for automatically removing rain from images taken by a vehicle-mounted camera, which considers raindrops as noise, first establishes a network model whose input and output are images at different times in the same scene in rainy days, and obtains the noise distribution of rainy days through the network model; then through The denoising network processes the rainy image to obtain a no-rain effect image.

[0024] refer to figure 2 , the rain removal method in the present embodiment specifically includes the following steps:

[0025] S1. Obtain samples. Each sample consists of two images at different times in the same rainy scene, and the image at the previous moment is used as the input image, and the image at the next moment is used as the output image.

[0026] S2. Establish a training sample data set and a testing sample data set each containing a plurality of samples, and combine the training sample data s...

Abstract

According to the automatic rain removing method for the vehicle-mounted camera photographed image, raindrops are regarded as noise, firstly, a network model with input and output being images at different moments in the same rainy day scene is established, and rainy day noise distribution is obtained through the network model; and processing the rainy day image through a denoising network to obtain a rain-free effect picture. According to the invention, training is carried out on the basis that input and output are samples of rainy day images at different moments in the same scene, so that rainy day noise distribution is obtained, and rain removal processing is carried out on the rainy day images with the rainy day noise distribution. Thus, according to the invention, the training of the model does not need a clean rain-free image, the data processing difficulty is simplified, the feasibility is improved, and the accuracy degree of data processing is ensured.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for automatically removing rain from images captured by a vehicle-mounted camera. Background technique [0002] At present, in the field of on-board camera photography and unmanned driving assistance system design, it is very difficult to analyze and process photography in rainy weather. Heavy rain often leads to blurred photography or heavy rain information interference, causing errors in the computer analysis system, and then malfunctions, increasing the risk of car accidents. For the removal of heavy rain in photos or videos, there is currently no mature solution. How to restore photos in a heavy rain environment to a rain-free environment will be crucial for vehicle-mounted photo analysis and driverless auxiliary analysis systems. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention...
