The invention provides a positioning method, device and system based on a visual image and a storage medium, and belongs to the technical field of computer vision. The method comprises the following steps: acquiring earth surface feature information based on a to-be-positioned image acquired by observing a to-be-positioned area by a user terminal; matching a contour line corresponding to the earth surface feature information and geographic position information of each contour point on the contour line from an earth surface form library; and determining the pose information of the user terminal in the geodetic coordinate system based on the pixel position information of the target contour point in the to-be-positioned image and the geographic position information of the target contour point. According to the invention, the earth surface image and form information when the to-be-positioned area is the satellite navigation denial area can be rapidly obtained by using space remote sensing, and the information is matched with the earth surface image, so that positioning efficiency and precision are taken into account while positioning and orienting are carried out in the satellite navigation denial area for individuals, unmanned aerial vehicles or light carriers.

The invention discloses a motor car automatic light control system based on computer vision assistance, and relates to the technical field of motor car automatic light control, and the system comprises a severe weather identification module, a light dynamic adjustment module and an intelligent control and feedback module. By arranging the multi-position high-definition camera outside the bullet train and applying a severe weather feature extraction algorithm, precise recognition of severe weather such as rainstorm, violent snow and dense fog is achieved, the problem that the severe weather recognition capacity of an existing system is limited is solved, and by means of a self-adaptive light regulation and control algorithm and a differential adjustment strategy for different types of lamplight, the recognition accuracy of the bullet train is improved. Light parameters are dynamically adjusted according to severe weather and ambient light intensity, contrast is enhanced, color temperature is adjusted, a comfortable light environment is created, visual experience of passengers is improved, sight of a driver is prevented from being interfered, information such as weather and running speed and geographic position of the bullet train is fused through an environment information fusion module, comprehensive and reasonable light adjustment is achieved, and the service life of the bullet train is prolonged. And the intelligent operation requirement of the bullet train is met.
