CAMERA ATTITUDE DETECTION DEVICE AND WORK REGION LINE DISPLAY DEVICE |
摘要 |
There is provided a monitoring camera (32) at a tip of a boom, a monitor (70) configured to display a captured image of a hook suspended from the tip of the boom, an attitude angle calculation device (68) configured to calculate, based on hook image position information on a screen displayed on the monitor (70) and hook position information in a real space, an attitude angle of the camera, and the attitude angle calculation device (68) includes a hook position calculation unit (63) configured to calculate a hook position on the screen actually displayed on the monitor (70), a shift amount calculation unit (64) configured to calculate the distance between the hook position calculated by the hook position calculation unit (63) and a reference hook position of the hook on the screen displayed on the monitor (70) when it is assumed that the camera faces directly downward, and a camera inclination angle calculation unit (65) configured to calculate an inclination angle of the monitoring camera (32) based on the difference and a distance in a height direction from an optical axis center position of the monitoring camera (32) to the hook. |
