This research and development project studied technology capable of identifying changes in roads using dashcam drive recorder images and probe vehicle data. These results were then applied to studies envisioning the rapid deployment of technology for identifying road changes. For the studies into technology capable of identifying changes in roads using dashcam drive recorder images, camera image data of existing sections of roads were obtained after changes were carried out. These studies then confirmed and assessed whether the changes to the road could be identified using existing technology to recognize features from the obtained camera image data, identifying those features after the road changed, and comparing the features with the state before the changes.
For the studies into technology capable of identifying changes in roads using probe vehicle data, the requirements for using probe data to update high precision 3D maps were examined on paper and then validated on a proving ground. This verification process confirmed that driving operations and vehicle behavior accompanying changes to roads can be identified using probe vehicle data in an ideal environment. Based on these results, consultations were held with OEMs about the provision of actual probe vehicle data, and the potential of using the provided real-world probe vehicle data to identify changes to roads was confirmed.
The studies envisioning the rapid deployment of technology for identifying road changes were carried out by (1) carrying out a field operational test (FOT) under a scheme envisioning the rapid deployment of technology after research and development, followed by the organization of requirements such as device specifications and the like. Then, after investigating the latest trends and so on, (2) the required conditions for starting operation on ordinary roads and globally were identified. The gap between the requirements identified at phases (1) and (2) were analyzed and summarized into a procedure for commonization.
