A collision avoidance system 10 for a large vehicle 12 (e.g. lorry) comprises means for detecting a vulnerable vehicle (e.g. bicycle 34); camera 38,39; and video display 36 that is activated to show a live feed from the camera when a vulnerable vehicle is detected. The detection means may comprise a radio receiver 30 (connected to antennas 14, 16, 18, 20) receiving a signal transmitted by a tag 32 on the bike. Alternatively vulnerable vehicles may detected by image recognition software â e.g. detecting an IR-reflective tag in the image (Fig.6). Video may be streamed from a camera selected, orientated and zoomed on the basis of the detected bicycle position. The video feed may be augmented to highlight the bike. A processor may determine whether the vulnerable vehicle is moving; likely to collide with the large vehicle; or exhibiting erratic or unpredictable motion. |
