Abstract

The invention provides a method for measuring the height of a human body in video images. The method comprises the steps of 1, decomposing video images comprising a target into a plurality of frames of series photos arranged in chronological order, 2, finding out key frame photos from the series photos, 3, adopting a computer having a video image and photo overlaying program and displaying the key frame photos on the display of the computer, 4, picking up the video images of the key frame photos by use of a camera placed in the original pick-up point and displaying the video images on the display of the computer as being overlaid on the key frame photos, and 5, according to the key frame photos and the video images at the key frame photos which are displayed on the display in the overlaying manner, instructing the measuring personnel by the computer operating personnel to go to the field, put the lower end of a sliding staff with a vernier against the position of the feet of the target in the key frame photos, pass the sliding staff with the vernier through the top of the head of the target and slide the vernier on the sliding staff to the top of the head of the target, and reading the height of the sliding staff indicated by the vernier, namely the body height of the target. The method for measuring the height of the human body in the video images is capable of measuring the heights of the human bodies in the video images conveniently and accurately.

Description

The measuring method of Human Height in video image
Technical field
The present invention relates to a kind of processing method of video image, particularly the measuring method of Human Height in a kind of video image.
Background technology
To important public place, in the management of important department and work, commercial business's industry, adopt video record monitoring system widely.Video record monitoring system can obtain the video image of accident in monitoring range effectively, and video image is the multiframe serial-gram arranged in chronological order, and video image has very large effect to the reason analyzing accident.In above-mentioned accident, often relating to the client in video image, if client is unknown human, for finding client, needing the characteristic obtaining client, Human Height is key character data of client.
At present, mostly the multiframe serial-gram decomposited by video image is it is digitized photo, video image and digitized photo can show on the computer display with video image and photo overlap-add, the relative data of the height of client on photo can be obtained by the client's height method measuring photo on display, due in the photo with client, there is no the length object of reference apart from client's certain distance, so the real Human Height of client can not be obtained by the be taken in relative data of thing people height of photo, if the client in photo is less, pixel in photo then on display included by client's length is also little, the client's height relative data deviation measured over the display is larger, when the pixel of client in photo arrives certain degree less, just can not record the relative data of client in the photo on display.
In prior art, there is no the measuring method of Human Height in video image.
Summary of the invention
The object of the invention is, in order to overcome above-mentioned deficiency, to propose the measuring method of Human Height in a kind of video image.
The present invention is achieved using the following method.
In video image, the measuring method of Human Height has the following steps:
1. get the video image with client, the video image with client is resolved into the multiframe serial-gram arranged in chronological order;
2. in the above-mentioned multiframe serial-gram arranged in chronological order, find out the photo that a frame best embodies client's Human Height when standing, as key frame photo;
3. get the computer with video image and photo overlap-add, above-mentioned key frame photo is schemed to show on a computer display as a setting;
4. the video camera that the former picked-up point being used in the video image of the above-mentioned client of having is placed absorbs the video image at scene, above-mentioned key frame photo place, and above computer display to overlap as foreground picture the video image at the scene, key frame photo place of absorbing with video camera to be shown with above-mentioned background figure;
5. at the video image with above-mentioned video camera picked-up scene, key frame photo place, and under the video image at crucial photograph frame and scene, key frame photo place is presented at the condition of above computer display with overlapping, the hand-held Sopwith staff with vernier of survey crew is allowed to enter the scene at above-mentioned key frame photo place, allow computer operator by the key frame photo of display and the video image at scene, key frame photo place that computer display overlaps, under instructing the survey crew at the scene of entering to implement that the Sopwith staff lower end with vernier is against client's foot of standing in key frame photo, allow the Sopwith staff with vernier by the crown of client, vernier on Sopwith staff is slided into the operation on the client crown, then namely the Sopwith staff height of vernier instruction is the Human Height of client.
The present invention's computer with video image and photo overlap-add to overlap over the display with the video image absorbing the video camera a little placed with key frame photo former and absorb above-mentioned key frame place show having the key frame photo that best embodies client's Human Height when standing, survey crew inserts the Sopwith staff with vernier at the scene, the key frame photo shown by computer display overlaps and the video image at key frame place, the Sopwith staff with vernier is stood under client's foot as length object of reference, allow the crown of Sopwith staff by client with vernier time, namely the Sopwith staff with vernier is the length object of reference of distance client certain distance, because the Sopwith staff with vernier is between the underfooting and the crown of client, so the height with the Sopwith staff instruction of vernier is exactly the Human Height of client.The present invention can measure Human Height in video image easily, exactly.
Below in conjunction with accompanying drawing, the present invention is further described.
