Description

Technical Field

[0001] The utility model relates to the technical field of unmanned vehicles, in particular to a vehicle positioning device. Background Art

[0002] Vehicle positioning technology plays a vital role in the transportation industry, rail transportation, cranes, coke oven vehicle equipment, heavy machinery, and transportation, especially in the fields of unmanned driving and automatic transportation. It is crucial to ensure that the vehicle can be accurately positioned, which is the basic premise for autonomous navigation. In this field, traditional single sensor positioning methods have obvious limitations because they often have difficulty coping with complex and changing environmental conditions.

[0003] At present, advanced technologies such as satellite positioning and visual positioning have been widely used in positioning systems, but they all have their own limitations. For example, satellite positioning may be affected by signal obstruction in some cases, resulting in increased positioning errors, while visual positioning is easily affected by lighting conditions and environmental influences, making it impossible to accurately collect images at night or in bad weather. In addition, the visual positioning system also relies on the identification of roadside positioning reference objects, which may face huge challenges in actual operation because it is often difficult to accurately identify similar roadside reference objects.

[0004] Therefore, in order to overcome these challenges, unmanned driving systems need to integrate multiple positioning technologies and use advanced sensors to ensure that vehicles can be accurately positioned in various complex environments, thereby achieving safe and reliable autonomous navigation.
