The invention provides an obstacle state quantity determination method and device, electronic equipment, a computer readable storage medium and a computer program product, relates to the field of computers, in particular to the field of automatic driving, and can be applied to scenes such as intelligent traffic and smart cities. According to the implementation scheme, the linear speed and the angular speed of a vehicle at a first moment and a subsequent second moment are obtained; determining a transformation matrix of a vehicle coordinate system corresponding to the vehicle from the first moment to the second moment based on the linear velocity and the angular velocity; the state quantity of the obstacle at the first moment is transformed through the transformation matrix, so that the state quantity at the first moment is transformed to be expressed in a vehicle coordinate system corresponding to the second moment; and determining the state quantity of the obstacle at the second moment based on the transformed state quantity.
本公开提供了一种障碍物状态量确定方法、装置、电子设备、计算机可读存储介质和计算机程序产品，涉及计算机领域，尤其涉及自动驾驶领域，可应用于智能交通、智慧城市等场景。实现方案为：获取车辆在第一时刻和随后的第二时刻下的线速度和角速度；基于线速度和角速度确定车辆对应的车辆坐标系从第一时刻到第二时刻的变换矩阵；通过变换矩阵对障碍物在第一时刻的状态量进行变换，以使得第一时刻的状态量变换为在第二时刻对应的车辆坐标系下进行表示；以及基于变换后的状态量确定障碍物在第二时刻的状态量。
