Embodiment Construction

[0051] Below, will refer to Figure 1 to Figure 5 A method for specifying location information according to the first embodiment of the present invention will be described.

[0052] In the present embodiment, it is assumed that the position and speed of the oncoming vehicle 1 are determined by photographing the oncoming vehicle 1 with a monitoring camera 2 such as a driving recorder mounted on the parked vehicle 10. .

[0053] Below, will refer to figure 1 The flow chart shown in FIG. 2 describes the method of measuring the position and speed of the oncoming vehicle 1 (the method of specifying the position information) according to the present embodiment.

[0054] First, acquire a plurality of target images 3 captured by the monitoring camera 2 within a specified time (refer to Figure 2(a)-Figure 2(c) ) (S11).

[0055] In the present embodiment, a plurality of frames constituting a video captured by the surveillance camera 2 are acquired as a plurality of target images 3 ...

Abstract

[Problem] Provide a position information determination method that can accurately determine the position and speed of the object to be photographed. [Solution] The position information determination method of the present invention includes: the step of acquiring the object image 3 captured by the monitoring camera 2 having a predetermined distortion characteristic related to the distortion generated in the captured image; The step of acquiring the first scale plate image 42 of the image obtained after a scale plate 4 is photographed, the first scale plate 4 has a first scale 41, and is arranged after being separated from the monitoring camera 2 by a first distance X ; The step of overlapping the first scale plate image 42 with the object image 3; using the first scale 41 on the first scale plate image 42, the first image with the first predetermined size B captured on the object image 3 The step of measuring the dimension A of the reference object 5 on the image; The step of the first object distance Y of object 5.

Description

technical field [0001] The present invention relates to a position information specifying method, a position information specifying device, and a position information specifying program for accurately specifying the position and speed of an object to be photographed. Background technique [0002] In the past, when a vehicle accident was photographed by a surveillance camera on the street or a driving recorder mounted on a vehicle, the speed of the accident vehicle at the moment of the accident was generally determined by the following methods: [0003] For example, when the accident happened just after crossing the pedestrian crossing line, the image frame of the instant when the front end of the accident vehicle reached the pedestrian crossing line and the instant image frame when the front end of the accident vehicle crossed the pedestrian crossing line were extracted by visual inspection, and then passed Divide the length of the crosswalk line by the time between these tw...
