The advantages are high precision and fast map acquisition speed, but the cost is high and the map size is large
[0004] The common disadvantages of these two modes are that the collection cost is too high, the map data formed is much, and post-processing is required. At present, the post-processing is basically manual processing, so all the costs are allocated to the end users. It is very expensive
At the same time, due to the large amount of map data, more processing time is required, resulting in low post-processing efficiency and affecting user experience

Abstract
The invention relates to the field of vehicle navigation, and provides a method, device and terminal for establishing a parking map in a non-signal area, and the method comprises the steps: obtainingpositioning information which is the positioning information when a vehicle enters the non-signal area; collecting surrounding environment information; inquiring a first map matched with the positioning information according to the positioning information, wherein the first map is a stored map; if the query result is empty, carrying out automatic parking according to the surrounding environment information; establishing a second map according to the surrounding environment information, and marking the second map through positioning information; according to the positioning information of the second map, judging whether a third map of which the positioning information is in the same area range exists or not; and if not, storing the second map. According to the method, the map can be updatedand expanded, map information is perfected, the personalized requirements of customers are better met, and the effect of updating the iterative map can be achieved through later cloud processing.
Description
technical field [0001] The invention relates to the field of vehicle navigation, in particular to a method, device and terminal for establishing a parking map in a no-signal area. Background technique [0002] With the continuous development of intelligent driving, the construction of indoor maps is particularly important. Among them, the most important function of using indoor parking lot is the valet parking function. Among them, the indoor parking lot often faces the problem of no map and unstable signal. In order to realize the valet parking function of the indoor parking lot, the high-precision map construction method of the map vendor is usually adopted, but the high-precision map construction method of the map vendor also exists. The problem of updates and high fees increases the cost of vehicles accordingly and reduces the popularity of this function. [0003] There are not many existing indoor mapping schemes that have been practiced. The main method is laser scann...
