Example Embodiment
[0061] Example 1
[0062] As attached figure 1 As shown, an embodiment of the sleeper bolt detection device of the present invention specifically includes:
[0063] The acquisition module 1 is triggered to acquire the position to be acquired of the sleeper bolt image. The trigger acquisition module 1 is mainly composed of a position sensor, a logic circuit, etc., can obtain position information of different precisions through configuration, and simultaneously transmit reference information such as multiple trigger signals and trigger indexes.
[0064] The image acquisition module 2 acquires the plane image data of the sleeper bolt 5 according to the position to be acquired. The image acquisition module 2 further includes a light source 30 and a camera 40. The image acquisition module 2 acquires plane image data of the sleeper bolt 5 according to the trigger pulse sent by the trigger acquisition module 1. When the current position of the image acquisition module 2 is greater than o...
Example Embodiment
[0087] Example 2
[0088] As attached Figure 5 And Image 6 As shown, an embodiment of a sleeper bolt detection method based on the device described in embodiment 1, specifically includes the following steps:
[0089] A) Acquire the position of the sleeper bolt image to be collected; first, the device is initialized, and the position to be collected for the first frame of sleeper bolt image is the value assigned when the sleeper bolt detection device 10 performs system initialization. When the current position of the image collection reaches the first frame of sleeper Collect a frame of image when the bolt image is to be collected at the position to be collected, and record the width W, height H of the collected image plane, and the current shooting position S 0 ;
[0090] As a preferred embodiment of the present invention, if a sleeper bolt is detected in the first frame of the captured sleeper bolt image, it is determined that the sleeper bolt image capture position is the positio...
