Vehicle restraint systems

A vehicle comprising:

• a restraint system comprising one or more belt tongues, one or more buckles configured to latch to the one or more belt tongues, and one or more straps each attached to at least one of the one or more buckles or at least one of the one or more belt tongues, wherein each strap of the one or more straps comprises one or more reflective sources;
• one or more sensors;
• one or more light sources;
• and
• a computing device configured to:
• receive, from the one or more sensors, image data while the one or more light sources are illuminating the restraint system;
• determine, based on the image data, a position for each of the straps;
• verify whether the position of each of the straps is in a respective predetermined location based on a position of a respective reflective source of the one or more reflective sources, wherein verifying whether the position of each of the one or more straps are in the respective predetermined location based on the position of the respective reflective source of the one or more reflective sources comprises, for each respective strap:
• determining a distance between the one or more reflective sources for the respective strap,
• calculating an angle for the respective strap, and
• determining whether the distance between the one or more reflective sources is within a predetermined distance range for the respective strap and the angle is within a predetermined angle range for the respective strap;
• and
• output an indication of whether each of the straps are in the respective predetermined location.

A method comprising:

• receiving, from one or more sensors of an aircraft, image data while one or more light sources are illuminating a restraint system, wherein the restraint system comprising one or more belt tongues, one or more buckles configured to latch to the one or more belt tongues, and one or more straps each attached to the one or more buckle or at least one of the one or more belt tongues, wherein each strap of the one or more straps comprises one or more reflective sources, and wherein the aircraft comprises the one or more sensors and one or more light sources;
• determining, based on the image data, a position for each of the straps;
• verifying whether the position of each of the straps is in a respective predetermined location based on the position of a respective reflective source of the one or more reflective sources, wherein verifying whether the position of each of the one or more straps are in the respective predetermined location based on the position of the respective reflective source of the one or more reflective sources comprises, for each respective strap:
• determining a distance between the one or more reflective sources for the respective strap,
• calculating an angle for the respective strap, and
• determining whether the distance between the one or more reflective sources is within a predetermined distance range for the respective strap and the angle is within a predetermined angle range for the respective strap;
• and
• outputting an indication of whether each of the straps are in the respective predetermined location.
