An automatic system for detecting an exterior damage to a vehicle, comprising: a. at least one camera installed in an image capturing lane for capturing "handover" and "return" sets of images of a vehicle that cover the entire external surface of the body of the vehicle during hand over and return of the vehicle, wherein each of the images within said sets is captured irrespective of the vehicle's movement or of the vehicle's orientation with respect to the capturing camera; b. a transformation unit which is configured to separately transform each pair of "handover" and "return" part-images, respectively, to a same plane, wherein said transformation further includes performing of one or more of: displacement, rotation and zoom of a first image relative to a second image in the pair; c. a comparison unit configured to separately compare pixel-by-pixel each of transformed pairs of "handover" and "return" part-images, to thereby detect a difference above a predefined threshold, and to alert when such a difference above the threshold is detected; the system is characterized by further comprising: d. a database for pre-storing images of basic-parts of at least one vehicle, wherein said basic-parts are selected from the vehicle door-handles, wipers, the right and left mirrors, the four wheels, the license plates, lights, and manufacturer's symbols; e. a first determination unit which is configured to, based on said pre-stored basic-parts images, determine the location of one or more basic-parts within images of said "handover" and "return" sets of captured images; f. a second determination unit which is configured to, based on said determined locations of the one or more vehicle's basic parts within the captured images, respectively, determine the locations of "other parts" existing at the exterior of the vehicle within said "handover" and "return" sets of images, wherein the "other parts" are generally larger parts of the vehicle such as doors, a front and a rear bumper, a roof and a hood, thereby to form said "handover" and "return" part-images, respectively, to be provided into said transformation unit, wherein said determination of the "other parts" by the second determination unit is based on constant relative locations between said "basic parts" and each "other part", respectively. a. at least one camera installed in an image capturing lane for capturing "handover" and "return" sets of images of a vehicle that cover the entire external surface of the body of the vehicle during hand over and return of the vehicle, wherein each of the images within said sets is captured irrespective of the vehicle's movement or of the vehicle's orientation with respect to the capturing camera; b. a transformation unit which is configured to separately transform each pair of "handover" and "return" part-images, respectively, to a same plane, wherein said transformation further includes performing of one or more of: displacement, rotation and zoom of a first image relative to a second image in the pair; c. a comparison unit configured to separately compare pixel-by-pixel each of transformed pairs of "handover" and "return" part-images, to thereby detect a difference above a predefined threshold, and to alert when such a difference above the threshold is detected; d. a database for pre-storing images of basic-parts of at least one vehicle, wherein said basic-parts are selected from the vehicle door-handles, wipers, the right and left mirrors, the four wheels, the license plates, lights, and manufacturer's symbols; e. a first determination unit which is configured to, based on said pre-stored basic-parts images, determine the location of one or more basic-parts within images of said "handover" and "return" sets of captured images; f. a second determination unit which is configured to, based on said determined locations of the one or more vehicle's basic parts within the captured images, respectively, determine the locations of "other parts" existing at the exterior of the vehicle within said "handover" and "return" sets of images, wherein the "other parts" are generally larger parts of the vehicle such as doors, a front and a rear bumper, a roof and a hood, thereby to form said "handover" and "return" part-images, respectively, to be provided into said transformation unit, wherein said determination of the "other parts" by the second determination unit is based on constant relative locations between said "basic parts" and each "other part", respectively.
