By using RGB color strips of color encoding structure-light, a method of color stripe edge detection based on color component intersection point is presented. The method changes the color strip images from RGB model to normalized color model l1 l2 l3 which is not influenced by the ambient light, shooting angles of CCD and the shape of the 3D objects. Then the color stripe edge detection is implemented by the color component intersection point of l1 l2 l3 model. And the deduce process of the color model transfer is given. The experiments prove that the maximum error of stripe edge detection is less than 0.4 pixel, and the average error of the stripe detection is less than 0.2 pixel, the variance is less than 0.1 pixel2.

Motor racing athletes in the closed-cockpit category are always facing life-threatening situations caused by heat stroke, especially in hot weather. We report here the development of a novel infrared-radiation-type eardrum thermometer, with a built-in earphone, which can be used for continuous measurement in GT car racing. We examined the accuracy of the system for core body temperature monitoring in 10 healthy volunteers (21.8 ± 1.0 (S.D.) yrs) using a temperature controlled water bath. In addition, we assessed the usefulness of the systemunder real racing conditions with 2 professional drivers in the practice session of 2010 SUPER GT International Series Round 4 MALAYSIA being held at the Sepang International Circuit. To examine accuracy two thermistor probes, one inserted into the ear canal and the other beneath the tongue, were used for measurements of eardrum and sublingual temperatures respectively. An infrared eardrum thermometer was inserted into the contra-lateral ear canal. The measured temperatures were recorded at 30-s intervals. The results showed good correlation between the infrared eardrumtemperature and both the direct eardrumtemperature (r = 0.994, n = 1119, p 0.001). The mean difference between these temperatures was + 0.09 °C, - 0.08 °C, and 1.96 S.D. was 0.21 °C, 0.44 °C, respectively. As for the field test, the systemfunctioned satisfactorily during real racing conditions performed on the racing circuit. These results suggest that our new systemcan be used in a race setting as a reliable core temperature monitor and could help to improve safety of motor sports.
