The invention discloses a vehicle and its display terminal system and a method for establishing a three-dimensional terrain database through it. The back of the vehicle display terminal is provided with a sonar detector, and the vehicle display terminal is provided with a gravity sensor. The method includes the following steps: when the vehicle display When the terminal enters the working mode of establishing a three-dimensional topographic map, the sonar detector detects the road conditions of the first road section to obtain the road condition data of the first road section, and establishes a preliminary topographic map of the first road section according to the road condition data of the first road section; When the vehicle is moving and arrives at the first road section, the body posture detected by the gravity sensor is used to simulate the ground information of the first road section; the ground information of the first road section is fitted with the preliminary topographic map of the first road section to obtain the first road section The three-dimensional topographic map of a road section, so as to ensure the accuracy of the three-dimensional topographic map, effectively simplify the complexity of building a three-dimensional topographic map, increase the speed of building a three-dimensional topographic map, and improve user experience.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a method for establishing a three-dimensional terrain database through a vehicle-mounted display terminal, a vehicle-mounted display terminal system and a vehicle. Background technique [0002] The car synchronous mapping and obstacle recognition method in the related art obtains the distance data between the car and the surrounding environment through sensor data, and uses the sensor data to construct a map around the car. However, there is a problem in the related technology that in order to obtain the environmental data around the vehicle, sensors need to be arranged around the vehicle, and multiple sensor data need to be processed, so the structure is relatively complicated. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is t...
