Abstract
The present application discloses a location detection method, an apparatus, a device and a readable storage medium, which relate to vehicle infrastructure cooperation and automatic driving in intelligent transportation. A specific implementation solution is as follows: after acquiring an initial location of a target object, a millimeter wave radar projects the initial location onto an upper interface and a lower interface of a road section respectively to obtain a first projection location and a second projection location, and then determines an accurate location of the target object according to the first projection location and the second projection location. In this process, the initial location is mapped twice to make full use of an association relationship between an installation point and installation environment, so that the target location is no longer an approximate location, but a precise location obtained according to geometric projection, which improves accuracy of location detection.
