The invention discloses an intersection track adaptive correction system and method based on environmental perception, and relates to the field of data processing. The system uses an environment perception method to carry out adaptive correction on a track. The method comprises the following steps: establishing a fixed feature database of an intersection; when the target vehicle has a predetermined distance from the intersection, synchronizing the database to the target vehicle, and establishing a static environment; combined data collection is executed, and real-time positioning of a current node target vehicle in a static environment is determined; analyzing the collection result, and determining a newly added static environment; initial track fitting is carried out based on the static environment and the newly added static environment, and an initial track fitting result is generated; step intervals are set, continuous data collection is executed, and a dynamic environment is determined according to a continuous collection result; and generating a compensation track according to the environment track of the dynamic environment, and carrying out self-adaptive correction. According to the invention, the problem of low track precision in the prior art is solved, and the technical effects of adaptive correction based on environmental perception and measurement precision improvement are achieved.
