Automatic driving preceding vehicle cut-in scene extraction method based on signal rule

The invention discloses an automatic driving preceding vehicle cut-in scene extraction method based on a signal rule. The method comprises the following steps: S1, acquiring driving data and position data of a vehicle, position relation data of a target vehicle and the vehicle, and video data synchronized with the driving data of the vehicle; s2, extracting a signal segment in a preset first time range according to a preset signal rule, and extracting a video segment, corresponding to the signal segment, in the video data in a preset second time range; and S3, performing scene marking on the video clip and storing the video clip. According to the invention, based on the automatic driving controller signal, the driving track of the target vehicle in the signal is identified by using the rule, so that whether the target vehicle enters the lane is judged and the video meeting the signal rule time period is extracted, thereby improving the extraction efficiency, liberating human resources and achieving higher ext
