Monitoring Nest Building in Mice and Leaf Movement of Kidney Beans Using an Infrared Range Camera

As infrared range cameras have recently become commercially available at reasonable cost, we have been trying to use the range camera for monitoring nest-building behavior in mice and leaf movement of kidney beans.Three-dimensional (3D) images represented the nest-building behavior clearlyandheight information was very useful for assessment of nesting procedures and nest's quality. And also, 3D images of leavesalso showed that upward and downward movementswere synchronized with photo and dark period cycle. The 3D images obtained from the range camera were enough quality to evaluate these phenomena. Consequently, we believe the range camera will be one of powerful tools likewise 2D camera in near future.
