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.

PT Global’s transmitters — More than meets the eye
PT Global offer a considerable range of transmitters and conditioners in both analogue and digital formats. PT110LC PT111LC The PT110LC, PT111LC and PT112LC are DIN rail mounted micro-controller based analogue transmitters commonly used with load cells. They have very high accuracy and long term stability with advanced design. Using an up to-date delta-sigma ADC and 16 bit DAC to achieve higher speed and accuracy these instruments give the system designers a lot of advantages towards increasing system...
Combatting bacteria growth in emergency tank showers
Emergency safety showers and eye wash stations are essential for sites where workers could come into contact with hazardous chemicals. In some environments providing this life saving equipment can be challenging, for instance a consistent supply of potable water cannot be guaranteed, or a tepid temperature can be difficult to maintain due to extreme ambient temperatures. In these instances, emergency tank showers provide a viable solution. However, because emergency tank showers can go unused for extended...
White Goods - Case Study
CompanySince it`s foundation in the 1950s, this company has grown to be one of the world`s largest manufacturers of white goods. It has 250 million customers, and continues to sell a product every 2 seconds in over 100 countries. Its washing machine plant makes extensive use of highly- automated production lines to produce more than 1 million machines a year.ChallengesVolume manufacturing of white goods is critically dependent on the efficient scheduling of each of the stages of manufacture. And as its customers...
Tailored Emergency Safety Showers for Remote ‘Super Giant’ Oilfield - Case Study
Background The Tengiz oilfield in Kazakhstan is one of the deepest developed super giant oil fields in the world, with further expansion projects in the pipeline. The aim of the Future Growth Project is to increase the daily production of crude oil to 850,000 barrels per day, a planned growth of 240%. Running simultaneously, the objective of the Well Head Pressure Management Project is to keep the existing plants full by lowering the flowing pressure at the wellhead and then boosting the pressure to the inlet...
Industrial wastewater treatment for FLATSCHER in Unken, Austria - Case Study
Unlocking a hidden opportunity Better business through better wastewater treatment and reuse The challenge: Reuse wastewater and boost operating margins Tiltable frames of the ANDRITZ SEPARATION filter press installed at Flatscher With no wastewater treatment system in place, FLATSCHER ERDBAU & SCHOTTERWERK Ges.m.b.H faced a number of challenges that were threatening the company’s business.A nearly full disposal pond, with slurry too fluid to transport but too thick to pump, had led to an acute...
