Zusammenfassung:	A data processing method and apparatus, a data transmission method and apparatus, a communication system, a vehicle, a computer readable storage medium, and a computer program product. The data processing method comprises: receiving a first message from a second device, wherein the first message comprises echo waveform data and first point cloud data, and the echo waveform data is used for indicating the sampling waveform of an echo and the detection orientation of a pulse wave corresponding to the echo in a space (S101); obtaining a point cloud correction parameter according to the first message (S102); receiving a second message from the second device (S103); and using the point cloud correction parameter to correct second point cloud data indicated by the second message (S104). The method improves the accuracy of the point cloud data of a laser radar. In addition, the transmission frequency of the first message is lower than the transmission frequency of the second message, and because the amount of data c
