The invention concerns a method for detecting an incident on a traffic lane portion (1) located in a landscape (2) when the lane portion is likely to be used by objects. The invention is characterized in that the method uses a video camera (3) comprising a target (4) constituting an optoelectronic converter of a real optical image of the landscape (2), the target being monitored by a programmable processing member (6) and the incident detection process being designed to be carried out by activating the programmable processing member (6) only when the real landscape image focused on the target (4) is stationary. The inventive method is characterized in that it consists in detecting the beginning of a displacement of the real image of the landscape relative to the target, in deactivating the programmable processing member right at the beginning of the displacement of the real image of the landscape relative to the target, and in reactivating the programmable processing member at the end of the displacement of the real image of the landscape relative to the target to carry out the incident detection process. |
