Patent number: 10718620Abstract: A navigation and positioning device including a storage, a mark feature analyzer, a first coordinate fusion component and a second coordinate fusion component is provided. The storage stores map information including a traffic mark feature and its mark coordinate. The mark feature analyzer is used for analyzing whether a captured image has the traffic mark feature. When the captured image has the traffic mark feature, the mark feature analyzer analyzes the traffic mark feature in the captured image and calculates a device coordinate according to the mark coordinate. The first coordinate fusion component fuses the device coordinate and a first fusion coordinate and uses fused coordinate as a second fusion coordinate. The second coordinate fusion component fuses the second fusion coordinate, traffic carrier inertial information and a global positioning coordinate and uses fused coordinate as an updated first fusion coordinate.Type: GrantFiled: December 21, 2017Date of Patent: July 21, 2020Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Ming-Xuan Wu, Yu-Yin Peng, Pin-Yung Chen, Che-Tsung Lin, Kang Li
