Visual outrigger monitoring system
A system and method for visually monitoring an outrigger includes a camera assembly configured to monitor an outrigger and a control system operably and communicably connected to the camera assembly. The control system executes instructions to determine a presence, length, and/or position of the outrigger based by an image captured by the camera assembly. The outrigger may include a target to be detected by the camera assembly for monitoring of the outrigger. The target may be the outrigger itself, detected by the control system using edge detection, or a marker disposed on the outrigger. The system may be implemented with a crane having a carrier unit and a superstructure. The system may include a plurality of camera assemblies and a plurality of outriggers.
1. An outrigger monitoring system, comprising:
a camera assembly configured to capture an image for monitoring a position of an outrigger; and
a control system operably and communicably connected to the camera assembly, the control system comprising a processor and computer readable storage media in communication with the processor, the computer readable storage media storing instructions that, when executed by the processor, cause the control system to implement functions comprising an image recognition function configured to receive the image from the camera assembly, detect an outrigger in the image, and determine an extension length of the outrigger based on the detected outrigger in the received image, wherein the functions further comprise an obstacle detection function configured to detect an object in a path of the outrigger based on the received image.
2. The outrigger monitoring system of claim 1 , wherein the outrigger includes a target, and the image recognition function comprises a target recognition function.
3. The outrigger monitoring system of claim 2 , wherein the target comprises one or more of an optical pattern on the outrigger and a high contrast color coating a portion of the outrigger.
4. The outrigger monitoring system of the claim 1 , wherein the image recognition function comprises an edge recognition function to detect an edge of the one or more outriggers.
5. The outrigger monitoring system of claim 1 , wherein the functions further comprise a motion detection function configured to detect motion in the field of view of the camera assembly.
6. The outrigger monitoring system of claim 1 , wherein the outrigger is one of a plurality of outriggers, and the camera assembly monitors more than one outrigger of the plurality of outriggers.
7. The outrigger monitoring system of claim 6 , wherein the camera assembly is one of a plurality of camera assemblies, each camera assembly configured to monitor more than one outrigger of the plurality of outriggers.
8. A crane comprising:
a carrier unit;
a superstructure mounted on the carrier unit;
at least one outrigger coupled to the carrier unit, the outrigger configured to extend and retract relative to the carrier unit; and
an outrigger monitoring system comprising:
a camera assembly configured to capture an image for monitoring a position of the at least one outrigger; and
a control system operably and communicably connected to the camera assembly, the control system comprising a processor and computer readable storage media in communication with the processor, the computer readable storage media storing instructions, that when executed by the processor cause the control system to implement functions comprising an image recognition function configured to receive the image from the camera assembly, detect the presence of the at least one outrigger in the image, and determine an extension length of the at least one outrigger based on the detected outrigger in the received image, and
a user interface, wherein the determined extension length of the at least one outrigger is displayed on the user interface.
9. The crane of claim 8 , wherein the camera assembly is mounted to the superstructure.
10. The crane of claim 8 , wherein the functions further comprise a function for determining a slew angle of the superstructure.
11. The crane of claim 8 , wherein the camera assembly includes a first camera assembly mounted to the superstructure at a first position and a second camera assembly mounted to the superstructure at a second position.
12. The crane of claim 11 , wherein the camera assembly further includes a third camera assembly mounted to the superstructure at a third position.
13. The crane of claim 11 , wherein the at least one outrigger includes a first pair of outriggers and a second pair of outriggers, the first camera assembly configured to monitor the first pair of outriggers and the second camera assembly configured to monitor the second pair of outriggers.
14. The crane of claim 8 , further comprising a jack coupled to a distal end of the at least one outrigger, wherein the functions further comprise a function for determining an extension of the jack.
15. The crane of claim 14 , further comprising a jack pad coupled to the jack, wherein the functions further comprise a function for determining the presence of the jack pad.
16. A method of monitoring a crane outrigger, comprising:
causing a crane to extend an outrigger;
visually monitoring the outrigger by capturing an image of the outrigger with a camera assembly;
detecting the outrigger in captured image;
determining an extension length of the outrigger based on the detected outrigger in the captured image; and
displaying the determined extension length on a user interface.
17. The method of claim 16 , wherein the outrigger has a target and wherein the extension length of the outrigger is detected by detecting the target.
18. The method of claim 16 , wherein the extension length of the outrigger is detected using edge detection of the image of the outrigger.
