A collision warning method is to be implemented by a collision warning system and includes: in response to determining that a neighboring vehicle is directly behind a subject vehicle based on a video, outputting a first warning notification in response to determining that a first warning condition related to a forward-backward distance threshold is satisfied; and in response to determining that the neighboring vehicle is obliquely behind the subject vehicle, generating a two-dimensional top-view image that presents a relative position between the subject vehicle and the neighboring vehicle, overlapping a blind-spot distribution pattern matching the neighboring vehicle on the two-dimensional top-view image, and outputting a second warning notification in response to determining that a second warning condition related to a left-right distance threshold and a blind-spot coverage threshold is satisfied based on the two-dimensional top-view image with the blind-spot distribution pattern overlapped thereon.
