- Description:
- A large number of logging safety accidents in cable operations occur as a result of poor visibility between yarder operators and individuals in the brush. Industrial safety campaigns, such as Weyerhaeuser Corporation’s ‘in-the-clear’ messaging, help to improve safety. However, reliance on audio communication with audio signals as the primary method for communications to ensure safety when the yarding of logs commences has some safety shortcomings that could potentially be improved upon. For example, if the yarder operator receives a signal to commence yarding when a choker setter has not yet moved fully into the clear, there is no back-up safety system to confirm the audio command. Recently, carriage-mounted agricultural cameras have been used to guide the acquisition of sawlogs by remote grapple carriages, such as the Eagle Yoder Claw Grapple and Eagle Mega Claw Line. A small agricultural camera is mounted on these carriage models. The grapple is operated remotely from the cab by the operator, who has a bird’s eye view of the area below the carriage on a 9 inch screen that is mounted in the cab. In this study, we are evaluating the potential use of inexpensive agricultural cameras and screens as a back-up, secondary safety measure in cable logging communications. We affixed an agricultural camera to a carriage on a Koller 300 series yarder used on the University of Idaho Experimental Forest, and also on a small, trailermounted mini-yarder. A designed experiment was conducted to evaluate the effects of image filtering methods, harvest type, and camera field of view on image contrast and visibility. Our objective was to determine whether a combination of remote sensing image filtering techniques could be used to clearly identify choker setters with very high contrast under a range of light and background conditions. Results of the preliminary experiment are reported and a larger operational pilot study is described.
