In a preferred embodiment of the invention, the distance between described generating laser and reflector is 0.3～5m.Error-detecting within the scope of this and correction are more accurate, more convenient.
In another preferred embodiment of the present invention, described generating laser, photographic plate and signal processor are as a whole.Integral body moves, more convenient when correction error, more efficient.
Another technical matters to be solved by this invention is that a kind of method that detects error vectoring error correction is provided.
For this technical matters, the technical solution of employing is to adopt the system for detection of error vectoring error correction of the present invention, and comprise the following steps:
1) generating laser is to reflector launching site laser, reflector will be put laser reflection to photographic plate, by photographic plate, detect the laser spots position that reflector reflects, and by laser spots position feedback to signal processor, signal processor is by comparing with the signal location of storage, whether have the direction of deviation and deviation, and flow to equipment control center during the fructufy that signal is processed if calculating target object position; 2) result showing according to equipment control center, the position of adjustment generating laser and/or reflector, to eliminate deviation.
In step 2) in when there is ultralimit, the deviation that mobile generating laser and/or reflector provide according to signal processor makes reflected light move to central point in the other direction, when the ultralimit point of reflected light from CCD jumps to central point, mobile platform continues to the radius distance of the limit range inner region of the mobile reflector of deviation opposite direction, reaching the limit of district center in scope is that the centre of location completes error correction guiding, and now the light source center of generating laser and the center of reflector are on same straight line.
By above step, can detect accurately, easily error and can to error, proofread and correct more efficiently.
