In the digital measurement for free-form surface, image mosaics are needed to achieve the whole measurement for the small measuring field of sensor unit.
自由曲面数字化测量中,由于传感器单元测量区域小,所以实现整体测量需要进行多次的图像拼接。

The small measuring field of sensor unit is the key problem in the free form surface measurement of large scale objects.
In the first section, to study the acoustic response properties of the IC in the pipistrellus abramus, single unit extracellular recording with microelectrode was used in freefield conditions.
