Abstract: PURPOSE: An accuracy comparing system and a method of target detecting sensor is provided to minimize the amount of time consumed and the cost for comparing the accuracy of the target detecting sensor. CONSTITUTION: An accuracy comparing system of target detecting sensor comprises a target sensing sensor(100), a first and a second camera(210,220), a time code generator(300) and a control device(400). A first and a second camera shoots the targets and generate a first and a second image respectively according to the photography result. A time code generator outputs a time code to coincide the measurement time of the detected information with a first and second image. A control device squares the detected information with a first and a second image of the spatial coordinated system and generates a 3D position data of the target using the corresponded spatial coordinate system with the first and second image. A control unit squares the 3D position data and the temporal coordinate system using a received time code from a time code generator and outputs the accuracy of the target detecting sensor by comparing the 3D location information which has unified the space and time with the detected information.
