The technical scheme that the present invention adopts for its technical problem of solution is, a kind of compensation arrangement of offset error is provided, and is used for camera head, comprises platform, offset sensor, computation module and actuating assembly.Platform has X-axis and Y-axis coordinate, and it is provided with device for solid photography.The offset sensor vicinity is arranged at by the device for solid photography, and the side-play amount of detecting device for solid photography.Computation module calculates offset error value based on side-play amount.Actuating assembly is disposed on the platform, and comes the reverse drive device for solid photography with by way of compensation according to offset error value, and wherein offset sensor is between device for solid photography and actuating assembly.
According to one embodiment of the invention, device for solid photography is charge coupled device.Offset sensor can be the magnetic strength assembly, as: Hall subassembly.Actuating assembly can be induction coil.
According to another embodiment of the present invention, offset sensor more comprises X, Y-axis skew sensing member, and side-play amount more comprises X, Y-axis side-play amount, when platform twists, and X, X, the Y-axis side-play amount of Y-axis skew sensing member in order to detect device for solid photography.As if 1 o'clock that only comprise X, Y-axis skew sensing member, offset error value was the range error value.If when comprising X, Y-axis skew sensing member simultaneously, offset error value is the angular error value, it is calculated and is got by X-axis side-play amount and Y-axis side-play amount.
Therefore, utilize the compensation arrangement of shift error of the present invention, can be when the platform torsion phenomenon take place, the offset error value that the minimizing offset sensor senses and actual offset error value gap, and then the more required compensation effect of closing to reality is provided.
Description of drawings
For above and other objects of the present invention, feature, advantage and embodiment can be become apparent, the description of the drawings is as follows:
Fig. 1 illustrates the structural representation according to the compensation arrangement of the offset error of an embodiment of the present invention.。
When Fig. 2 illustrates the generation of platform torsion phenomenon, device for solid photography and the side-play amount schematic diagram that is offset sensing component.
Embodiment
Please refer to Fig. 1, it illustrates the structural representation according to the compensation arrangement 100 of a kind of offset error of an embodiment of the present invention.The compensation arrangement 100 of offset error comprises platform 140, offset sensor 120 and actuating assembly 130.Platform 140 has X-axis and Y-axis coordinate, and it is provided with device for solid photography 110, and is provided with at least one axis hole group 150 around the device for solid photography 110.The contiguous sides that are arranged at device for solid photography 110 of offset sensor 120 when platform 140 twists, are detected the side-play amount of device for solid photography 110 in the mode of the gap error of ignoring axis hole group 150.That is to say that when platform 140 twisted, for actuating assembly 130, the offset sensor 120 of homonymy was homophase and approximate with the side-play amount of device for solid photography 110.Thus, offset sensor 120 just can be avoided the error that cause in the gap (between axle and the hole) of axis hole group 150.And computation module (not icon) returns and gives actuating assembly 130 just based on behind the side-play amount calculating offset error value.Actuating assembly 130 also is disposed on the platform 140, but than offset sensor 120 away from device for solid photography 110, and come reverse drive device for solid photography 110 to reach the compensation of offset error according to offset error value.
Please refer to Fig. 2 again, when it illustrates the generation of platform 140 torsion phenomenon, the side-play amount schematic diagram of device for solid photography 110 and offset sensor 120.Can be known by Fig. 2, when platform 140 twists, device for solid photography 110 around axis hole group 150 the axle with the hole between have the gap that cooperates, and cause the skew nonsynchronous situation, just produce gap error.But because offset sensor 120 neighbor configuration are in a side of device for solid photography 110, therefore when platform windup-degree θ, just know under the same angle from the trigonometric function concept, the more near then side-play amount of distance is more accurate, so the side-play amount d1 of device for solid photography 110 can be less than the side-play amount d2 of offset sensor 120.And when offset sensor 120 is contiguous when being placed on device for solid photography 110 peripheral, the mode that offset sensor 120 can be ignored the gap error of axis hole group 150 is detected the side-play amount of device for solid photography 110, in other words, the side-play amount d2 of the side-play amount d1 of device for solid photography 110 and offset sensor 120 approached in ten minutes, and can reach sensing usefulness more accurately.That is to say, by the mode of offset sensor 120 between device for solid photography 110 and actuating assembly 130, make the real offset of offset sensor 120 quite near the real offset of device for solid photography 110, so configuration mode is reached sensing usefulness more accurately.
During actual fabrication, aforementioned device for solid photography 110 can utilize charge coupled device to implement.Offset sensor 120 can be the magnetic strength assembly, as: Hall subassembly etc.Actuating assembly 130 can be induction coil.
And according to another embodiment of the present invention, offset sensor 120 more comprises X, Y-axis skew sensing member, and side-play amount more comprises X, Y-axis side-play amount, when platform 140 twists, and X, X, the Y-axis side-play amount of Y-axis skew sensing member in order to detect device for solid photography.If only comprise among X, the Y-axis skew sensing member at 1 o'clock, offset error value is the range error value.If when comprising X, Y-axis skew sensing member simultaneously, offset error value is the angular error value, it is calculated and is got by X-axis side-play amount and Y-axis side-play amount.
By the invention described above execution mode as can be known, using the present invention can be when the platform torsion phenomenon takes place, the offset error value that the minimizing transducer senses and actual offset error value gap, just can dwindle deviant that moment sensor senses and the gap of actual shifts value, and then the more required compensation effect of closing to reality is provided.
