The invention relates to the technical field of artificial intelligence image detection, and discloses a vehicle driving state judgment method and device, computer equipment and a storage medium, andthe method comprises the steps: obtaining a vehicle driving video, extracting continuous key frames in the vehicle driving video, and calculating the driving speed of a vehicle according to two adjacent key frames; calculating the acceleration of the vehicle according to the vehicle speeds of the two adjacent key frames; carrying out discrete data fitting analysis on the acceleration of each key frame to obtain an acceleration line; judging whether the slope of the acceleration line is lower than a preset abnormal threshold value or not; if the driving state of the vehicle is lower than the abnormal threshold value, judging that the driving state of the vehicle is abnormal. The invention also relates to a blockchain technology, and information can be stored in the blockchain node. According to the invention, the abnormal driving state of the vehicle can be intelligently identified, and the problems of poor timeliness, inaccurate information and false case report of traffic accidents inthe prior art are solved.

    本发明涉及人工智能的图像检测技术领域,公开了一种车辆行使状态判断方法、装置、计算机设备及存储介质,包括:获取车辆行驶视频并提取其中连续的关键帧,根据相邻的两个关键帧计算车辆的行驶速度;根据相邻的两个关键帧的车辆速度计算车辆的加速度;对各关键帧的加速度进行离散数据拟合分析得到加速度线条;判断所述加速度线条的斜率是否低于预设的异常阈值;若低于所述异常阈值,则判定所述车辆的行使状态为异常。本发明还涉及区块链技术,信息可存储于区块链节点中。本发明实现了智能识别车辆异常的行驶状态,解决了现有技术中存在的车祸报案时效性差、信息不准确以及虚假报案情况的发生。
