针对人工校正报靶系统的不准确性，提出了一种无线超声报靶系统的图像校正技术。采用轮廓提取的方法获取靶纸上的有效区域，对有效区域采取自动获取控制点的方法进行几何校正，获得与模板图像大小相同的正视靶纸图片，再利用训练好的级联分类器识别校正后的靶纸上的弹孔，最后利用最小二乘法计算出靶纸上弹着点的实际位置。向超声靶射击3枪，记录超声信号获得的3个弹着点位置，将其与弹着点的实际位置进行比对即可获取报靶系统的修正值，再将修正值用于弹着点的校正当中，即可实现靶纸更换后弹着点位置的自动校正。较之传统的人工校正方法更加方便快捷，减少人为因素造成的校正不准，避免实弹训练时报靶误差的产生。

An image correction technology applied to wireless ultrasound target-record system is proposed to avoid the inac-curacy of manual correction. The contour extraction method is adopted to obtain the effective area on the silhouette paper,and then method to automatically get control points on the effective place is used to conduct geometric correction and get the front view target sheet picture which is same size as template image. The corrected bullet holes on the paper are recognized by a trained cascade classifier. The least squares fitting method is used to calculate the actual location of the bullet holes on the pa-per. Three bullets shoot on the ultrasound target and the locations of three impact points are obtained by recording the ultrasonic signal. The revised value of the ultrasound target-record system can be got by comparing them with the actual positions of the im-pact points. Compared with the traditional manual correction method,the wireless ultrasound target-record system is more conve-nient,can reduce the inaccuracy caused by artificial correction,and also can avoid the record error of shooting training.
