PROBLEM TO BE SOLVED: To perform an all-object evaluation of vehicle accuracy correctly as well as at a low cost.SOLUTION: The vehicle accuracy evaluation system includes a robot arm 10 disposed around a manufacturing line 1, and a distance sensor provided at the tip of the robot arm 10 and measuring a distance to a prescribed portion 4 of a vehicle 3. The distance sensor, which is a laser displacement sensor 11 for radiating a slit-shape laser beam L, by making the tip of the robot arm 10 move its position while irradiating the laser beam L, performs a scan over a prescribed portion 4 with the laser beam L, and on the basis of a distance to the prescribed portion 4 measured by the laser displacement sensor 11 and a tip position of the robot arm 10, detects a position of the prescribed portion 4. 【課題】車両精度の全数評価を正確かつ低コストに行う。【解決手段】本発明に係る車両精度評価システムは、製造ライン１の周囲に配置されるロボットアーム１０と、ロボットアーム１０の先端に設けられ、車両３の所定部位４までの距離を測定する距離センサとを備える。距離センサは、スリット状のレーザー光Ｌを照射するレーザー変位センサ１１で、レーザー光Ｌを照射しながらロボットアーム１０の先端を移動させることで、レーザー光Ｌによる所定部位４の走査を行い、レーザー変位センサ１１で測定した所定部位４までの距離と、ロボットアーム１０の先端位置とに基づき、所定部位４の位置を検出する。【選択図】図１
