摘要：Internet offers a new direction for software development and also for photogrammetry. The affordable commercial digital cameras are widely available and their geometrical resolution is good enough to perform photogrammetric measurements. Seeing this, a widely accessible, web based photogrammetry application could be a new development direction for photogrammetry. For photogrammetric calculations Direct Linear Transformation is a well useable method as it does not need calibrated camera. The potential users are in the lack of experience, therefore the calculation method should be prepared to help them to achieve high accurate results. For example, gross errors in measurements cannot be avoided but the impacts of gross errors should be avoided. This study shows a technique how to reduce effects of gross errors with Huber-method and discusses the investigation for results
