発明の名称
(EN) IMAGE ANALYSIS DISTANCE INFORMATION PROVISION SYSTEM, METHOD, AND PROGRAM
(ZH) 图像解析距离信息提供系统、方法以及记录介质
要約
(EN) The present invention provides technology whereby the distance between an imaging device and an object to be photographed can be measured. This image analysis distance information provision system (1)comprises a computer device (10) and an imaging device (20). From an image of an object to be photographed captured by the imaging device (20), a control unit (11) for the computer device (10): (1) specifies the type of the object to be photographed; (2) calculates the actual length of the object to be photographed, per unit length in the image of the object to be photographed; (3) calculates theimaging range for the image of the object to be photographed, from said calculation results; and then (4) estimates the distance from the imaging device (20) to the object to be photographed, from the calculated imaging range.
(ZH) 本发明提供一种能测定拍摄装置与拍摄对象物体之间的距离的技术。本发明的图像解析距离信息提供系统(1)具备计算机装置(10)和拍摄装置(20)。计算机(10)的控制部(11)根据由拍摄装置(20)拍摄到的被拍摄对象物的图像,经过(1)被拍摄对象物的种类的确定、(2)被拍摄对象物的图像的每单位长度的被拍摄对象物的实际长度的计算、(3)根据该计算的结果进行被拍摄对象物的图像的拍摄范围的计算,(4)根据计算出的拍摄范围,推测从拍摄装置20至被拍摄对象物的距离。
