Description

Technical Field

[0001] The present invention relates to the field of visual inspection, and in particular to a display system and a display method for a long object visual inspection picture. Background Art

[0002] At present, there are many practical applications for visual inspection of long objects (such as high-speed trains, subway trains, etc.), such as visual inspection of the appearance of long objects. To visually inspect long objects, you first need to take pictures, and take pictures at close range with a small field of view, which leads to a large number of visual inspection pictures of a long object (hundreds or thousands). At the same time, in order to ensure the inspection efficiency and the application of the inspection results, the visual inspection pictures of long objects will not use area array cameras (there will be overlapping area problems), but use linear array cameras. The linear array camera scans the long object line by line, outputs a piece of image data according to the specified number of lines to the external terminal device for inspection, and the image data will be saved in the storage medium of the terminal device after the inspection is completed. The linear array camera will not output data after scanning the entire long object and inspect it on the external terminal device, because the scanned data of the entire long object can reach several GB or even tens of GB, which requires too high performance configuration of the linear array camera or terminal device and exceeds the existing hardware configuration technology. This is also one of the reasons why there are more visual inspection pictures of long objects.

[0003] The pictures generated for the above scenarios have two characteristics: a large number and a visual connection. The pictures are used in visual inspection scenarios, and the display and viewing of the pictures have the following requirements: seamless splicing display, fine movement and zoom viewing. However, viewing the pictures of the above scenarios on current terminal devices cannot meet the above requirements at the same time. For example, on the PC side, the table format or list format is generally used, such as Figure 1 , Figure 2 shown.

[0004] There are three problems with table or list display:

[0005] 1) Picture-level display, seamless splicing display cannot be achieved;

[0006] 2) Image-level movement, the unit is fixed and rough, and the movement unit is a single image or a multiple relationship;

[0007] 3) Image-level zooming, not visual-level zooming, requires switching between adjacent images, especially where adjacent images are joined.

[0008] Even though there are applications that solve the above problems 1 and 2 in the image display method of the mobile terminal device, there is no application method that solves problem 3. Therefore, there is no display and viewing method for the above images and appeals in the current terminal device. Summary of the invention

[0009] In order to solve the above technical problems, the present invention provides a display system and a display method for visual detection images of long objects, which can realize seamless splicing, fine-level movement and scaling of visual detection images of long objects, and can also seamlessly splice and display the visual detection images of long objects on a terminal device, and can support fine-level (mouse operation or touch screen operation) movement and scaling.

[0016] Furthermore, the external input signal capture module can also obtain a signal of enlarging or reducing the position of the image to be viewed input by the external input device compared to the current position, and transmit it to the logic processing module;

[0018] The window module also includes a zoom module, which can enlarge or reduce the image I according to the area to be displayed determined by the logic processing module, so that the image area displayed in the display window is consistent with the area to be displayed.
