The invention discloses a track inspection platform line scanning imaging control signal generation device and a signal generation method. The device is mounted on an inspection platform and comprisesmarking patterns, a light source, an imaging module, a data processing and signal generating module and a fixed box. The marking patterns are driven to rotate through a rotating axle of the inspection platform; the imaging module images the marking patterns, matching the same marking patterns in an image sequence, calculates the displacement of the marking patterns in unit time, and calculates the motion speed of the inspection platform; and according to the motion speed and imaging resolution requirements, PWM waves with corresponding frequencies are generated as line scanning control signals.

    本发明公开一种轨道巡检平台线扫描成像控制信号发生装置及信号产生方法,该装置挂载于巡检平台上,包含标记图案、光源、成像模块、数据处理与信号发生模块、以及固定盒。通过巡检平台的旋转车轴带动标记图案转动;成像模块对标记图案成像,对图像序列中相同标记图案进行匹配,计算出单位时间内标记图案位移,并由此计算巡检平台运动速度;根据运动速度和成像分辨率要求,产生对应频率的PWM波,作为线扫描控制信号。
