A system for simultaneous measurement of "Wheel alignment angles" and "Wheel runout" of multi-axle vehicles having more than two axles, said system comprising: a plurality of wheel targets , wherein each of said plurality of wheel targets is respectively mounted on said axle wheels ; only four camera modules ; two vertical columns , one on each side of a multi-axle vehicle , one vertical column fixed with two camera modules at defined heights which cover one side of the vehicle and the other vertical column fixed with two camera modules at defined heights which cover the other side of the vehicle , wherein each of said camera modules includes a camera , wherein simultaneously, the cameras included in each of the camera modules mounted on both the vertical columns are configured to capture images of said plurality of wheel targets , so that more than two images of wheel targets are captured at the same time in a single camera ; wherein on each of said vertical columns , the one camera module is positioned at a height lower than the other camera module in such a way that the bottom camera module is set to focus on the front axle wheels to up to three axles at a time and the top camera module is set to focus on the rear axle wheels to up to three axles at a time; and an alignment control module having a processor co-operating with each of said camera modules and configured to analyze said captured images to simultaneously compute "wheel alignment angles" for each of said axle wheels and also to simultaneously compute "wheel runout" for each of said axle wheels , said processor further configured to compare said computed wheel alignment angles with a predetermined range of acceptable wheel alignment angles. a plurality of wheel targets , wherein each of said plurality of wheel targets is respectively mounted on said axle wheels ; only four camera modules ; two vertical columns , one on each side of a multi-axle vehicle , one vertical column fixed with two camera modules at defined heights which cover one side of the vehicle and the other vertical column fixed with two camera modules at defined heights which cover the other side of the vehicle , wherein each of said camera modules includes a camera , wherein simultaneously, the cameras included in each of the camera modules mounted on both the vertical columns are configured to capture images of said plurality of wheel targets , so that more than two images of wheel targets are captured at the same time in a single camera ; wherein on each of said vertical columns , the one camera module is positioned at a height lower than the other camera module in such a way that the bottom camera module is set to focus on the front axle wheels to up to three axles at a time and the top camera module is set to focus on the rear axle wheels to up to three axles at a time; and an alignment control module having a processor co-operating with each of said camera modules and configured to analyze said captured images to simultaneously compute "wheel alignment angles" for each of said axle wheels and also to simultaneously compute "wheel runout" for each of said axle wheels , said processor further configured to compare said computed wheel alignment angles with a predetermined range of acceptable wheel alignment angles. <EOS>
