Drift optimization systems for vehicle-mounted machines based on global positioning systems

A drift optimization system for a vehicle-mounted machine based on a global positioning system (GPS), comprising a vehicular sensor, a camera unit, a GPS receiver, a memory, and a processor of a current vehicle, wherein

• the vehicular sensor is configured to obtain environmental parameters and vehicle parameters;
• the camera unit is configured to obtain the environmental parameters and a count of vehicles in a preset range;
• the GPS receiver is configured to receive a navigation signal sent by a navigation satellite;
• the memory is configured to store a secure GPS point set and intermediate data generated during drift optimization;
• and
• the processor is communicatively connected with the vehicular sensor, the camera unit, the GPS receiver, and the memory, and the processor is configured to:
• set a datum point;
• determine a classification result of a GPS position by judging each GPS position in a GPS position sequence acquired from the GPS receiver during a preset time period, the classification result including at least one of a secure GPS position, a high precision GPS position, or an abnormal GPS position;
• in response to determining that the GPS position is the secure GPS position, send a first command, the first command instructing the memory to store the GPS position to the secure GPS point set;
• in response to determining that the GPS position is the abnormal GPS position and all first N1-1 GPS positions prior to the GPS position in the GPS position sequence are abnormal GPS positions, reset the datum point;
• wherein N1 is a preset value;
• in response to detecting that the secure GPS point set in the memory is full, determine whether a count of the high precision GPS position in the secure GPS point set is greater than or equal to a set count threshold;
• in response to determining that the count of the high precision GPS position in the secure GPS point set is greater than or equal to the set count threshold, construct a motion trajectory of the current vehicle based on the GPS position in the secure GPS point set;
• and
• in response to determining that the count of the high precision GPS position in the secure GPS point set is less than the set count threshold, send a second command and reset the datum point, and the second command is configured to instruct the memory to empty the secure GPS point set.
