The image acquisition unit 31 acquires an image signal within a set range in which the writing tip 21 is in contact with the writing surface, and processes the image signal into a digital image signal to output to the image processing unit 32. The setting range depends on the focal length and depth of field setting of the image acquisition unit 31. In specific implementation, corresponding parameters can be selected for setting according to actual needs.
The image processing unit 32 is connected with the image acquisition unit 31, and is used for preprocessing the digital image signal and determining whether the focus of the image acquisition unit 31 is coincided with the writing end 21; the overlapping is not limited to one point, but includes overlapping within the same range. Preferably, this range coincides with the above-mentioned set range, or is smaller than the above-mentioned set range.
When it is determined that the focal length error between the focal point and the writing tip 21 is greater than a preset first threshold value, an adjustment control signal is generated according to the focal length error, and the adjustment section 13 is controlled by the adjustment signal, thereby changing the angle setting between the first fixing section 11 and the second fixing section 12.
Specifically, the adjusting unit 13 may be a unit having an automatic adjusting function, or may be a unit for manual adjustment by an operator.
