The embodiment of the invention provides a visual enhancement method and device for a vehicle and a storage medium. The method comprises the following steps: acquiring multi-mode environment sensing data around a vehicle through at least one distance measuring sensor and at least one optical imaging sensor carried on the vehicle; data of a global positioning system receiver, an inertial measurement unit and a wheel speed encoder are fused, and state information of the vehicle is determined through filtering; based on sensing data of the distance measuring sensor, detecting and tracking surrounding obstacles by using an obstacle detection and tracking algorithm to obtain dynamic information of the surrounding obstacles; performing real-time path planning by utilizing a path planning algorithm based on the state information, the dynamic information and the map data so as to generate a dynamic navigation path; processing sensing data of the optical imaging sensor to generate enhanced visual information; and superposing the enhanced visual information and the dynamic navigation path to form an enhanced visual interface.

This utility model discloses a handheld portable lightning warning device, including a circuit board, a shell, a cover plate, a 4G antenna and a Beidou antenna, a signal receiving circuit, an alarm circuit, and a main control circuit. The main control circuit is connected to the 4G antenna, the Beidou antenna, the signal receiving circuit, and the alarm circuit. This utility model achieves positioning and tracking through the 4G antenna and the Beidou antenna, making it easier for users to identify directions in the wild or in areas with weak signals, thereby ensuring user safety. Furthermore, the signal receiving circuit, the main control circuit, and the alarm circuit sense early low-intensity weak discharges and noise changes of lightning within a range of 5-15 kilometers, providing timely audible and visual warnings of nearby or impending lightning discharges to remind users to take shelter from lightning and protect their safety.
