The application provides a kind of electronic rearview mirror flicker suppression method and related device, method includes: according to original image data, vehicle state data and environmental data, whether target vehicle is in flicker trigger working condition is judged;If it is judged that target vehicle is in flicker trigger working condition, then according to flicker trigger working condition type, target flicker suppression strategy is determined;According to original image data, target flicker suppression strategy is executed, and target image data is obtained.The frame rate of image acquisition equipment, the frame rate of electronic rearview mirror chip image processing and the refresh rate of image display device are set to the same 50HZ, which is conducive to solving the phenomenon of imaging lagging and incoherence, suppressing power frequency flicker, and by identifying different flicker trigger working conditions and executing different flicker suppression strategies, it is conducive to improving the accuracy of flicker suppression.

The application provides a kind of animation style virtual person animation real-time generation method and system, comprising: extracting multidimensional style features from animation reference map, wherein multidimensional style features include line drawing features, color features, texture features and character form features;From real-time captured portrait video, extract portrait key point sequence and interactive object sequence, and generate dynamic semantic identity anchor point stream according to interactive object sequence;With portrait key point sequence as structural constraint condition, with multidimensional style features as global guidance, dynamic semantic identity anchor point stream is embedded into latent space as hidden variable constraint, and controlled diffusion reasoning is carried out in latent space, to obtain animation latent feature frame sequence;Three-dimensional causal decoding and time domain smoothing filtering are carried out on animation feature frame sequence, to obtain smooth animation frame sequence;Real-time style feedback and style correction are carried out on smooth animation frame sequence, to obtain virtual person animation.

The application relates to the technical field of computer vision, and discloses a picture splicing method based on multiple cameras. The method comprises the following steps: acquiring multiple image frames collected synchronously; correcting and aligning the images; constructing an initial pixel-level difference cost map; combining a previous frame splicing seam to generate a space-time guide weight map; fusing to obtain a dynamic optimization cost map; performing shortest path search in a limited area to determine a current best splicing seam; and generating a seamless splicing image by weighted fusion according to the current best splicing seam. By introducing a space-time guide mechanism and an edge preservation factor, the calculation complexity is reduced, the splicing continuity and visual quality are guaranteed, and the method is suitable for high-dynamic scenes such as vehicle-mounted surround view and unmanned aerial vehicle aerial photography.
