System and method of controlling construction machinery

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

an upper camera installed in a driver cabin of the construction machinery to photograph the front of the driver cabin;

a lower camera installed in a vehicle body of the construction machinery to photograph the front of the vehicle body;

a work apparatus posture detection portion configured to detect a posture of the work apparatus connected rotatably to the vehicle body;

an image processing portion configured to synthesize first and second images captured from the upper camera and the lower camera into one image, and configured to transparency-process at least one of the first and second images in the synthesized image according to the posture of the work apparatus detected by the work apparatus posture detection portion; and

a display device configured to display the synthesized image transparency-processed by the image processing portion,

wherein the image processing portion transparency-processes the first image in the synthesized image when at least a part of the work apparatus invades a predetermined position, and the image processing portion transparency-processes the second image in the synthesized image when the work apparatus does not invade the predetermined position.

2. The control system of claim 1 , wherein the entire display area of the display device includes a predetermined transparency processing area and an external area of the predetermined transparency processing area, and the image processing portion processes the first and second images to be transparent in the predetermined transparency processing area.

3. The control system of claim 1 , further comprising:

an input portion configured to set an image processing condition in the image processing portion.

4. The control system of claim 3 , wherein the image processing condition includes a transparency processing switching timing of the first and second images or a predetermined transparency processing area of the entire display area of the display device.

5. A method of controlling construction machinery, the method comprising:

obtaining a first image of the front of a driver cabin of the construction machinery from an upper camera installed in the drive cabin;

obtaining a second image of the front of a vehicle body of the construction machinery from a lower camera installed in the vehicle body;

detecting a posture of a work apparatus connected to the vehicle body;

synthesizing the first and second images into one image;

transparency-processing at least one of the first and second images in the synthesized image according to the detected posture of the work apparatus; and

displaying the transparency-processed image through a display device,

wherein transparency-processing the at least one of the first and second images comprises:

transparency-processing the first image in the synthesized image when at least a part of the work apparatus invades a predetermined position; and

transparency-processing the second image in the synthesized image when the work apparatus does not invade the predetermined position.

6. The method of claim 5 , wherein the entire display area of the display device includes a predetermined transparency processing area and an external area of the predetermined transparency processing area, and the first and second images are processed to be transparent in the predetermined transparency processing area.

7. The method of claim 5 , further comprising:

setting an image processing condition for transparency processing of the first and second images.

8. The method of claim 7 , wherein the image processing condition includes a transparency processing switching timing of the first and second images or a predetermined transparency processing area of the entire display area of the display device.

9. Control system for construction machinery, the control system comprising:

an upper camera installed in a driver cabin of the construction machinery to photograph the front of the driver cabin;

a lower camera installed in a vehicle body of the construction machinery to photograph the front of the vehicle body;

an image processing portion configured to synthesize first and second images captured from the upper camera and the lower camera into one image, and configured to transparency-process at least one of the first and second images in the synthesized image; and

a display device configured to display the synthesized image transparency-processed by the image processing portion,

wherein the entire display area of the display device includes a predetermined transparency processing area in which the transparency-processed image is displayed and an external area of the predetermined transparency processing area, and

wherein the image processing portion processes the first and second images to be transparent in the transparency processing area when at least a part of the work apparatus is located within the transparency processing area.

10. The control system of claim 9 , further comprising:

an input portion configured to set an image processing condition in the image processing portion.

11. The control system of claim 10 , wherein the image processing condition includes a transparency processing switching timing of the first and second images or a size and location of the predetermined transparency processing area of the entire display area of the display device.
