For effective in situ endoscopic diagnosis and treatment, size measurement and shape characterization of lesions, such as tumors, is important. For this purpose, in the past we have developed a range of 3D endoscopic systems based on active stereo to measure the shape and size of living tissues. In those works, the main shortcoming was that the target area could only be reconstructed at a specific...
This paper shows that experimental results for three-dimensional odor plume tracking using a multicopter with semiconductor-type gas sensor array. The 3D gas tracking aerial robot for monitoring of forest fire is developed, and the quadcopter has four gas sensor pairs put on under each rotor to expose the sensors to localized airflow made by rotors, which the sensor pairs will be prepared to detect...
For endoscopic medical treatment, measuring the size and shape of the lesion, such as a tumor, is important for the improvement of diagnostic accuracy. We are developing a system to measure the shapes and sizes of living tissue by active stereo method using a normal endoscope on which a micro pattern projector is attached. In order to perform 3D reconstruction, estimating the intrinsic and extrinsic...
