1. method that is used in checkout area optical measurement vehicle '"'"' mechanism, wherein, the sensor of other sensitive surface geometric properties of at least two camera heads (2) corresponding mutually on orientation and position by a camera assembly or the measurement assembly of another sensitive surface geometric properties carries out orientation to this assembly or these assemblies with respect to checkout area by means of the reference mark that is arranged on the checkout area, and analyze in the evaluation device (3) based on the directional data that is obtained and/or configuration data and measured zone data at one, quoting vehicle body mark (K1, K2,) situation under, carry out analytical calculation to determine the traveling mechanism data, it is characterized in that, individually or except not describing the measurement field coordinate system fully, be fixedly installed on the reference mark (R1 on the checkout area, R4) outside additionally, locate a standard apparatus (9) that on checkout area, uses movably, unified measurement field coordinate system of summation definition by these reference marks, in higher level'"'"'s measurement mechanism, obtain the directional data and/or the configuration data of camera head (2) and/or measuring unit (1) thus, after vehicle sails on the checkout area, by the camera head (2) of orientation in the measurement field coordinate system and/or the coordinate that measuring unit (1) determines to be arranged on the vehicle body mark on the vehicle, learn at vehicle body mark (K1 based on this information, K2 ...) layout in the measurement field coordinate system and can use so that analyze evaluation device (3) and the irrespectively definite traveling mechanism data of described reference mark for each camera head (2) and/or measuring unit (1) thus.
