Embodiment Construction

[0027] In the embodiment of the present invention, it is determined whether the irradiation direction of the high beam is consistent with the collection direction of the image collection device according to the lightness and darkness of two symmetrical regions in the image sample of the working point of the construction machine collected by the image collection device. If not, Then control the rotation of the high beam, so that the irradiation direction of the high beam is consistent with the collection direction of the image acquisition device, so that even at night, clear images can still be collected, which is convenient for the night operation of construction machinery.

[0028] The control of high beam rotation in construction machinery is an automatic process, see figure 1 , including:

[0029] Step 101: Obtain an image sample of an operating point of a construction machine collected by an image acquisition device.

Abstract

The invention discloses a control method, device and system of rotation of a headlight on full beam in an engineering machinery, which are used for enhancing the automatic control degree of the engineering machinery and reducing resource consumption. The method comprises the following steps of: obtaining an image sample of an operation point of the engineering machinery, collected by an image collecting device; processing the image sample; respectively determining a first intensity of a first side region and a second intensity of a second side region in the image sample, wherein the first side region and the second side region are two regions, which are symmetrically distributed on the two sides of a middle axis in the image sample and have equal areas; and when the difference between the first intensity and the second intensity does not fall within a set range, determining that a control parameter is released to an operation device, so that the operation device controls the headlight on full beam to rotate according to the control parameter.

Description

technical field [0001] The invention relates to the technical field of heavy machinery, in particular to a method, device and system for controlling the rotation of high beam lights in engineering machinery. Background technique [0002] An industrial camera that can control the shooting direction is installed on the working bucket of the aerial work vehicle, which is used to let the operator on the turntable or on the ground clearly understand the environmental conditions around the target working point. However, when working at night, it is necessary to turn on the high beam installed on the work bucket and on the same vertical plane as the industrial camera, and the high beam must be able to illuminate the same place as the shooting direction of the camera, so that the operator can See a clear image of the target work point. [0003] At present, the direction of the high beam can be adjusted manually by the operator on the working bucket to keep it consistent with the di...
