An optical path device, an optical detection method and a detection device, the optical path device comprising a side incidence optical path assembly and a lens assembly, the side incidence optical path assembly comprising a detection light source and an expander mirror set, the detection light source providing an incident light beam, the expander mirror set being configured to spread and shape the incident light beam in a first direction to form parallel first direction detection light beams and to spread and shape the incident light beam in a second direction to form non-parallel second direction detection light beams; the first direction detection light beams exiting the lens assembly to form a light spot on a surface to be detected of an object to be detected; the second direction detection light beams non-parallelly entering a surface of the lens assembly and having a beam size, the second direction detection light beams exiting the lens assembly to the surface to be detected and forming the light spot. The present application provides a detection optical path avoiding a central aperture of the lens assembly, which can effectively reduce the risk of lens damage and achieve more reliable and efficient wafer defect detection.

The present application relates to the technical field of image processing, and discloses an image processing method and device, a vehicle, a storage medium and a program product, wherein the present application determines the scene label of a target driving scene by acquiring multi-modal environment perception data. Then, the joint parameter mapping table is queried based on the scene label to match the target joint parameter corresponding to the target driving scene, the target joint parameter including a pair of first parameter group and second parameter group, and the synergistic constraint relationship existing between the first parameter group and the second parameter group can effectively inhibit the gain conflict caused by the opposite image gain trend of the two groups of parameters. The first parameter group and the second parameter group are used to control the first image processor and the second image processor to perform image processing and optimization in turn to obtain a target image, and the algorithm synergistic processing of the image acquisition end and the image display end is established, so that the picture quality degradation caused by algorithm conflict is avoided while adapting to various driving scenes, and the display effect of the vehicle-mounted image is significantly improved.
