On May 22, Kuaiji Technology reported that the summer was scorching. At present, Gaode Map has launched "sunscreen navigation" in 100 cities, so that users can feel the coolness blocked by shadows when traveling.
So what black technology is used to realize the sun protection navigation of Goddard?
According to reports, On the basis of ensuring the rationality of the original route planning, sun protection navigation can intelligently recommend cool routes with more shadows around the road through remote sensing, dynamic light and shadow tracking and other technologies.
According to common sense, shadows change with the position of the sun. For this reason, Gaud also designed and implemented a set of dynamic light and shadow computing technology.
It mainly calculates a relative angle between the sun and the ground based on time and geographical location, and then calculates a shadow shape of each shelter in any time period by combining remote sensing and image recognition technology recognition, as well as shelter information such as buildings.
Then, combined with the powerful basic network access information of Gaode, the shadow coverage area of each road in any time period can be calculated. Finally, when users travel, the proportion of shadows on each path will be calculated in real time according to the user's navigation time, that is, the sun protection navigation seen by most people now.
