The invention discloses a holographic vehicle track correction algorithm for data abnormity of road sensing equipment, and solves the problem that the authenticity and reliability of a holographic digital road vehicle track are reduced due to disordered point clouds and abnormal positions of millimeter-wave radar in the prior art. Comprising the following steps: S1, acquiring position points of each exit lane of a current intersection, and numbering the exit lanes; s2, calculating the current target exit lane of each vehicle according to the existing track of each vehicle in the current intersection; s3, calculating the position relationship among the current vehicles in the intersection; and S4, on the basis of the position relationship among the vehicles, deviation correction based on the target exit lane is carried out on the vehicles in the intersection in sequence, and vehicle track deviation correction is realized. When the original trajectory data of the road sensing device deviates abnormally, the vehicle trajectory in the holographic digital road is rectified in time, and the authenticity and reliability of the vehicle trajectory in the holographic digital road are effectively improved.
