Visual tracking and measurement is one of the most important tasks in computer vision and finds applications in traffic surveillance, vision-guided mobile robots, etc. In this paper, a binocular vision system is used to achieve the visual servoing, mimicking the movements of human eyes. First, a robust scheme, which combines adaptive Background Subtraction (BS) and Camshift algorithms, is proposed to detect and track a moving object. Then, we discuss the problems of camera parameter calibration and position measurement of moving objects. A new approach is introduced to realise the extrinsic parameter calibration of a pan-tilt camera, providing successful tracking and accurate measurement of a moving target, even as it is outside the view of the camera. Numerous experiments have been done on the binocular vision system of a humanoid mobile platform, and the results show that the proposed approaches work very well.

LED Applications for Oil and Gas Refining and Processing
Oil and gas processing facilities are unsafe due to the existence of hazardous compounds during operations. When addressing such issues, companies in the sector may deploy explosion proof lighting systems to prevent the ignition of sparks created from the electrical equipment. The adoption of LED technology in oil and gas refineries has helped reinforce key safety measures associated with premature light failure, costly maintenance and unpredictable work environments. This trend will likely continue to increase,...
How to choose open cell or closed cell articulated concrete blocks
Are you wondering what the best, most cost-effective solution is for erosion control at your construction site? There are a variety of solutions available, but we always highly recommend the use of articulated concrete blocks. These systems are a great alternative to what can otherwise be a costly, time-consuming task in erosion control. Articulated concrete block systems can be used in a wide range of applications, from roadway construction to waterway restoration, which makes them an extremely popular choice...
Case study - CAIROX CR potassium permanganate tablets
PROBLEMHydrogen sulfide (H2S) results from septic conditions during the collection and treatment of wastewater. H2S has long been recognized as a major problem for municipal wastewater systems. This colorless gas, known for its rotten egg smell, is produced by the biological reduction of sulfates and the decomposition of organic material. It forms at virtually every point in a system from interceptors, force mains and lift stations, to holding tanks, mechanical dewatering equipment, and drying beds. H2S also...
What is a wastewater treatment system and how does it work?
For industrial companies producing wastewater as part of it’s process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate wastewater treatment system will help the facility avoidharming the environment, human health, and a facility’s process or products (especially if the wastewater is being reused). It will also help the facility curb heavy fines and possible legal action if wastewater is being improperly...
Real-time monitoring for reduced chemical maintenance
We are pleased to be featured in this month’s American Laundry Newsdigital edition, together with our customer Walter E. Nelson,a janitorial, paper and chemical distributor in the Northwest that provides a wide range of laundry products and equipment. Jerry Roberts, of Walter E. Nelson, explains how he has experienced a significative improvement in the way his technical teams are able to monitor and make detergent adjustements for large laundries, thanks to our Dositec multiwasher chemical dispensing...
