Only two geographic features were included, the X and Y axis values where the fire occurred, since the type of vegetat ion presented a low quality (i.e. more than 80% of the values were missing). After consulting the Mon-tesinho fire inspector, we selected the month and day of the week temporal variables.
Time-of-Flight Camera – An Introduction
www.ti.comusing a low-cost CMOS pixel array together with an active modulated light source. Compact construction, easy-of-use, together with high accuracy and -rate makes TOF cameras an frame attractive solution for a wide range of applications. In this article, we will cover the basics of TOF operation, and compare TOF with other 2D/3D vision technologies.
