Problems solved by technology

Since the triggering time and trigger source of the sensors installed on the vehicle may be different, there may be a problem of asynchrony between multiple sensors and multiple sensors of each sensor. Therefore, how to implement multiple sensors and each sensor Synchronization between multiple sensors in is a problem worthy of study

Embodiment approach

[0173] Figure 8 A schematic flowchart of a sensor data processing method provided in an embodiment of the present disclosure, such as Figure 8 As shown, an optional implementation manner of the above step S702 includes:

[0174] S801. Determine the coordinate system of the first sensor at the detection moment of each sub-data according to the pose of the smart device at the detection moment of each sub-data.

[0175] The process of determining the coordinate system at each detection moment is the same as the aforementioned process of determining the first coordinate system at the first moment, and reference may be made to the foregoing embodiments, which will not be repeated here.

[0176] S802. According to the coordinate system of the first sensor at the detection time of each sub-data except the third time and the coordinate system of the first sensor at the third time, respectively determine that each sub-data except the third time is at The sub-data corresponding to t...

Abstract

Embodiments of the present disclosure provide a sensor data processing method, device, electronic device, and system. The method includes: acquiring first target data of a first sensor of a vehicle at a first moment; acquiring data of a second sensor of the vehicle at a second moment the second target data, the first moment and the second moment are different moments under the clock of the vehicle; obtain the first posture of the vehicle at the first moment and the second moment at the second moment The second pose, the first pose and the second pose are different; according to the first pose and the second pose, perform compensation processing on the first target data to obtain the first pose Compensation data of a sensor at the second time instant.

Description

technical field [0001] The embodiments of the present disclosure relate to intelligent driving technologies, and in particular, to a sensor data processing method, device, electronic device, and system. Background technique [0002] Assisted driving and automatic driving are two important technologies in the field of intelligent driving. Through assisted driving or automatic driving, the occurrence of traffic accidents can be reduced, so they play an important role in the field of intelligent driving. The implementation of assisted driving technology and autonomous driving technology requires the cooperation of various sensors. A variety of sensors are installed at different positions of the vehicle, and collect road images and vehicle operation data in real time. The assisted driving system or the automatic driving system performs control operations such as path planning according to the data collected by each sensor. Since the trigger timing and trigger source of the sens...
