System and method for controlling construction machinery

A control system for construction machinery, the control system comprising:

• an upper camera installed in a driver cabin of a rear body to capture a front view of the driver cabin;
• a lower camera installed in a front body rotatably connected to the rear body to capture a front view of the front body;
• a steering angle determiner configured to recognize a shape of the front body in the first image captured from the upper camera and to determine a refraction angle of the front body;
• an image processor configured to synthesize the first and second images into one synthesized image, and to set a position of a transparency processing area in which at least one of the first and second images is transparency-processed in the synthesized image according to the refraction angle of the front body determined by the steering angle determiner;
• and
• a display device configured to display the synthesized image transparency-processed by the image processing device,
• wherein the steering angle determiner is configured to extract a shape of a boom of the front body from the first image through an edge algorithm, and to apply Hough Transform to the extracted shape of the boom to calculate the steering hinge angle of the front body.
