Abstract
A coordinate locating method for determining the coordinate position of the dot to be measured on a picture includes generating a blank picture by picture generator (LCD or projector), respectively moving a sensor to the left, right, bottom and top boundaries of said blank picture, respectively recording their coordinates as initial and terminated horizontal and vertical coordinate values, calculating the length and width of the blank picture, and determining the coordinate of the dot to be measured.
Description
Invention field
The present invention relates to the coordinate location method that a kind of measuring pictures is subjected to measuring point, particularly relate to the coordinate location method that a kind of LCD measurement is subjected to measuring point.
Background technology
See also Fig. 1, Fig. 1 shows the checkout equipment of available liquid crystal display (LCD), wherein, and at the transport platform 120 other x-y mobile platforms 140 of placing, one sensor 130 is set on the x-y mobile platform 140, and x-y mobile platform 140 can make sensor 130 move along x axle or y direction of principal axis.On transport platform 120, be placed with many LCD to be measured 110,110 ' ..., transport platform 120 along the arrow A direction carry in regular turn each LCD 110,110 ' ... tested to the sensor 130, and make tested LCD 110 be connected in computing machine 150 with artificial or automation, provide signal to show test pictures by computing machine 150 to LCD 110, receive the light signal that is subjected to measuring point (representing) of LCD 110 and be returned to computing machine 150 by sensor 130 again, to judge whether this LCD 110 is non-defective unit with round dot.
Defined by the operator in advance by measuring point, when detecting, move to the position that is subjected to measuring point by x-y mobile platform 140 driving sensors 130 and read the light signal.The present known mode that two kinds of alignment sensors are arranged, first kind is come out by the coordinate calculated in advance of measuring point, directly makes sensor move to corresponding position when detecting; Second kind is in instruction robot mode, lead robot (being x-y mobile platform 140) to go the rounds once by the operator according to needed path, controller (or computing machine 150) by robot is remembered path and sequence of movement all, later guidance without the operator, just can repetitive operation action in the memory, detect remaining LCD 110 ' ....
Yet above-mentioned two kinds of methods, LCD to be measured must fall within same position accurately when entering measurement zone, can not allowable error, when so sensor is measured LCD to be measured, just can measure all at same position at every turn,
Summary of the invention
The object of the present invention is to provide a kind ofly to be different from traditional method and to come alignment sensor, even even LCD to be measured has a little displacement, sensor still can all accurately be measured the corresponding measuring point that is subjected on the LCD at every turn, improves the correctness of measuring.
The present invention carries out according to the following step: at first make a picture generation apparatus produce a complete white picture, move a sensor then, make the left side edge place of the complete white picture of sensor alignment, the horizontal coordinate of record sensor this moment is the base level coordinate figure then.Then, movable sensor makes the right side edge place of the complete white picture of sensor alignment, and the horizontal coordinate of record sensor this moment is for stopping the horizontal coordinate value then.Then, movable sensor makes the lower edge place of the complete white picture of sensor alignment, and the vertical coordinate of record sensor this moment is initial vertical coordinate value then.Then, movable sensor makes lateral edges place on the complete white picture of sensor alignment, and the vertical coordinate of record sensor this moment is for stopping the vertical coordinate value then.Then according to measured level and vertical coordinate value, calculate the length and the width of complete white picture, can be subjected to the coordinate setting of measuring point according to this level and vertical coordinate value and base level and vertical coordinate value.
For above-mentioned purpose, feature and the advantage that makes the present invention can become apparent, preferred embodiment cited below particularly also cooperates appended accompanying drawing to elaborate.
