Abstract
Cumulative trauma disorders (CTDs) are a leading cause of disability which generates huge direct
and indirect costs in the construction industry. Existing efforts identify the risk of CTDs through survey
or observatory studies which are subjective and expensive. This paper attempts to automatically identify
the risk of CTDs on construction sites with the aid of a video surveillance system. Specific emphasis is
placed on low back disorders (LBDs) which is one of the major workrelated CTDs. To this end, a risk
identification method is proposed based on location changes of region of interests in the resulting video
streams at minimum supervision. It is used to detect repetitive trunk flexionextension motions, awkward
trunk postures, and assess risk of jobrelated LBDs. Preliminary experimental analysis on lab datasets
demonstrates the promise of the proposed method.
