Novel memory parking system and mapping system thereof

Abstract

The invention relates to a novel memory parking system and a mapping system thereof. Camera selection modules are added in mapping and positioning, and compared with simultaneous use of multi-view cameras, a large amount of calculation amount is saved, the requirement for hardware is reduced, and the robustness of the system is ensured; compared with mapping only using a single camera, the success rate of mapping and positioning is improved, and the overhead of computing resources is not increased too much. Namely, different visual fields of different cameras are utilized in a visual angle switching mode, the overall performance of mapping and positioning is improved under the condition that a small amount of calculation is added; if paths are the same and directions are opposite in a taxi calling function, a map in a parking stage can be reused, user operation is simplified, and the application value of the systems in the autonomous parking market is high.

Description

technical field [0001] The invention relates to the technical field of automobile parking, in particular to a novel memory parking system and a mapping system thereof. Background technique [0002] In the memory parking function, the user needs to create and memorize the map and driving track when parking. Load the memory during subsequent parking, and perform matching and positioning based on real-time detected features and map features to obtain the position and orientation of the vehicle on the map, and then transmit the positioning information to the control system to guide the vehicle to complete parking. According to demand, a car-calling function can be added to respond to the user's call to drive out of the parking space and go to the designated destination. [0003] In the current memory parking products, cameras are widely used to participate in mapping and positioning, and multiple cameras are generally installed on the vehicle to observe the environment from dif...

Problems solved by technology

If a camera is used, not only the success rate is affected by a single viewing angle, for example, the scene lacks texture in a certain viewing angle, but also, even if the driving path of parking is the same as the path of calling a car, it may be due to the opposite driving direction, and the observation during positioning and mapping The difference in viewing angle is too large, and the map features cannot be accurately matched. As a result, the map in the parking stage cannot be reused for car calling. It needs to be rebuilt independently, which increases user operations and is cumbersome to use.
