Image projection apparatus

A vehicle comprising:

• a projector configured to project images on to a road surface;
• a first plurality of sensors configured to measure conditions outside of the vehicle, wherein the first plurality of sensors include at least one sensor that acquires comparison images of the images projected by the projector on the road surface;
• a second plurality of sensors configured to measure parameters of the vehicle;
• a processor communicatively coupled to the first plurality of sensors, the second plurality of sensors and the projector, wherein the processor:
• receives, from the first plurality of sensors, the comparison images,
• receives, from the second plurality of sensors, the parameters of the vehicle,
• determines a projection image based on the parameters of the vehicle,
• calculates an amount of correction required for the projection image based on the comparison images,
• on a condition that the amount of correction required is less than a threshold,
• corrects the projection image by the correction amount to form a corrected image, and
• controls the projector to project the corrected image on the road surface;
• and
• on a condition that the amount of correction required is not less than the threshold,
• controls the projector to not project the projection image on the road surface.
