DATA FUSION

A data fusion method and apparatus, and an applicable system. The applicable system comprises a vehicle (1), the vehicle (1) is provided with a lidar (2) and at least one image sensor (3), where the lidar (2) acquires a point cloud in by rotating a laser transmitter. A processor (5) is configured to acquire a rotation angle of a laser transmitter of the lidar (2) (S200), select, according to a predetermined correspondence between at least one rotation angle interval and the at least one image sensor (3), an image sensor (3) corresponding to a rotation angle interval in which the obtained rotation angle of the laser emitter is located as a specified image sensor (3) (S202), send a trigger signal to the specified image sensor (3), to enable the specified image sensor (3) to acquire an image (S204), receive the image and a point cloud that is acquired and returned by the lidar (2) within the rotation angle interval in which the obtained rotation angle is located (S206), and fuse information of pixels in the image and information of points in the point cloud according to pose change information of the vehicle (1) in a process of acquiring the image and the point cloud (S208).
