The invented system is in the fields of digitalization of plane-figure and area measurement. The invention relates to the digitalization of borderline figure by photoelectronic scanning. The computer automatically picks up, from the digitalized figure information, all the geometrical features of the pattern spots and displays directly on the screen with every figure spot being pointed out for establishing correspondent relation of the spots and codes. The said system can precisely measure the figure area with high precision and is applicable to geographical information system, remote-sensing mapping, agriculture, animal husbandry, fishing, hydraulic power and power departments. |
