Free space detection is one of the techniques for constructing safe driving support and autonomous driving. In this paper, we focus on narrow roads and describe the free space detection algorithm for constructing a narrow road driving support system. By installing the stereo camera in front of the vehicle, it is possible to perform object recognition and distance measurement without other external sensors. The installation position of the camera and the pitch angle of the camera are also used for detection of free space. The evaluation method is performed by comparing the detection result image with the previously prepared correct answer image. We are considering two kinds of evaluation methods based on the area and contour of free space.
In this paper, it is described the example of using the integrated data collection system developed by the authors in an evaluation demonstration experiment of the labor-saving effect of agricultural work by wearing an assist suit. The first author has been requested by Kumamoto Prefectural Agricultural Research Center Production Environment Research Institute to carry out the contracted research from December 2020 to March 2021. As part of the test research project "Evaluation of the effect of laborsaving agricultural work by introducing assist suits in Reiwa 2 (2020)", the degree of autonomic nerve activity and muscle activity are investigated using dedicated equipment, and to quantify the effect of labor-saving agricultural work by wearing an assist suit is the purpose. In order to evaluate the labor-saving effect, "stress evaluation by autonomic nerves", "reduction rate of muscle activity" and "motion analysis by a video" are required, and as measuring devices, heart rate sensor, EMG sensor, and video camera are used. However, since the various measuring instruments owned by the authors are separate systems, it is impossible to synchronously acquire the respective data. Therefore, it is very burdensome for the analyst to manually adjust the acquisition timing of each data after the experiment is completed, and it is difficult to perform perfect synchronization. Therefore, it is reported to be able to facilitate the acquisition of data for demonstration experiments by using the system the authors developed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
