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.

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...
Eight Ways to Avoid Catching and Spreading the Flu
WHAT’S AT STAKEEvery year, millions of workers are infected with a contagious respiratory illness: influenza, commonly known as the flu. Many workers who are sick with the flu refuse to let the illness prevent them from working, thinking they can “tough it out.” So they go to work with a reduced ability to work safely and productively, and they jeopardize the health of their co-workers. WHAT’S THE DANGERThe flu virus is easily spread, mainly through droplets made when someone who has the...
Antifreeze Windshield Washing Liquid
In cold season nonfreezing liquid for windshield washer along with gasoline are virtually the only consumable materials for a car. It seems impossible to not use this product, because it allows the driver to maintain visibility of the traffic situation and helps reduce the number of car accidents. Antifreeze is used in all cars regardless of their brand and manufacture year. The use of summer liquid or water in winter is a reckless step. In this article we will not focus on all the positive qualities of windshield...
