| 摘要 |
The invention relates to computer engineering and can be used for image sensing by visual sensor, quick selection of threshold cut, image binarization and determination of object location on image, dimensions, area and speed thereof, as well as first moments and gravitational center thereof. A sensor device for the determination of object location and gravitational center comprises a sensor array which row outputs are connected to inputs of row moment evaluator correspondingly, and columns outputs are connected to inputs of column moment evaluator correspondingly, outputs of row moment evaluators and column moment evaluators are connected to first and second inputs of microprocessor. First output of microprocessor is connected through digital-analog converter to third “Threshold” input of the sensor array, the microprocessor second output is connected to second “Reset” input of sensor array, the microprocessor third output is connected to first “Left shift” input of sensor array and to row spacing counter, the microprocessor fourth output is connected to fourth “Down shift” input of sensor array and to column spacing counter, the microprocessor fifth output is connected to fifth “Binarization” input of sensor array, the microprocessor sixth and seventh outputs are connected to control inputs of counters of row spacing and column spacing correspondingly. |
