Abstract

The invention discloses a map updating system, a related method, a related device and related equipment. The map updating method comprises the following steps: acquiring road environment image data, and determining pose data of mobile equipment at an image acquisition moment; according to the image data and the pose data of the current moment and the plurality of historical moments, determining a first corresponding relation between the road feature observation elements of the road segments and map elements; adjusting the observation element at the current moment according to the first corresponding relation; and updating map elements corresponding to the pose data at the current moment according to the adjusted observation elements at the current moment. By adopting the processing mode, a camera sensor and a low-cost positioning device which are arranged on common mobile equipment are adopted, the accuracy of local relative measurement is improved, the defect that the accuracy of measurement of the camera sensor and the positioning device is insufficient is overcome, and real-time accurate change detection of map data of a mobile equipment end is achieved; therefore, relatively low cost of the mobile equipment and relatively high map updating accuracy can be taken into account.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and specifically relates to a map updating system, method and device, electronic equipment, and mobile equipment. Background technique [0002] In mobile device positioning scenarios such as autonomous driving, indoor robots, and drones, mobile device positioning technology based on environmental maps can be used. Taking autonomous driving as an example, this technology allows the use of high-performance equipment or complex methods to obtain a map with a preset level of clarity in advance. During real-time positioning, the mobile device obtains real-time observation data through sensors, and then combines the observation data with the map. The data is registered to obtain the pose data of the mobile device. [0003] Map production can be divided into data collection, data processing, manual verification and other links. Among them, data collection requires a special data co...
