Title:
MOBILE TYPE OPTICAL ENVIRONMENT MEASURING DEVICE
Document Type and Number:
Japanese Patent JP3837552
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make measurable quickly an optical environment in a forest having a large spatiotemporal fluctuation without performing survey, installation of quadrat and measuring equipment.
SOLUTION: This device is equipped with the measuring equipment 5 for measuring the optical environment, and a moving barrow 4 loaded with the measuring equipment and running on the ground by one wheel. The measuring equipment 5 has one or a plurality of optical sensors 5a-5c, and an optical data recording device 7 for recording outputted data acquired by detecting light by the optical sensor together with the position and the detection direction of the optical sensor. The moving barrow 4 has a measuring position/direction operation device 7 for determining the position and the detection direction of the optical sensor at the measuring time by the optical sensors 5a-5c based on autonomous navigation information from an acceleration sensor 9 and a rotation angle sensor 10 for detecting respectively the acceleration and the rotation angle of the barrow and moving distance information from a wheel rotation sensor 8, and imparting them to the optical data recording device 7.
