sba, a C/C++ package for generic sparse bundle Adjustment is almost invariably used as the last step of every feature-based multiple view reconstruction vision algorithm to obtain optimal 3D structure and motion (i.e. camera matrix) parameter estimates. Provided with initial estimates, BA simultaneously refines motion and structure by minimizing the reprojection error between the observed and predicted image points.

The purpose of this application note is to show an example of how a digital potentiometer can be used in thefeedback loop of a step-up DC-DC converter to provide calibration and/or Adjustment of the output voltage.The example circuit uses a MAX5025 step-up DC-DC converter (capable of generating up to 36V,120mWmax) in conjunction with a DS1845, 256 position, NV digital potentiometer. For this example, the desiredoutput voltage is 32V, which is generated from an input supply of 5V. The output voltage can be adjusted in35mV increments (near 32V) and span a range wide enough to account for resistance, potentiometer and DCDCconverter tolerances (27.6V to 36.7V).

為了解決磁放大器性能測(cè)試過(guò)程中，需要對(duì)其供給不同數(shù)值恒定電流的問(wèn)題，設(shè)計(jì)了一種基于DAC7512和單片機(jī)的數(shù)控恒流源系統(tǒng)。該系統(tǒng)采用AT89C51作為主控器件，將計(jì)算機(jī)發(fā)送的電流控制字命令轉(zhuǎn)換為D/A轉(zhuǎn)換器控制字，通過(guò)模擬SPI通信接口，寫(xiě)D/A控制字到DAC7512，從而控制其輸出相應(yīng)數(shù)字電壓值，經(jīng)差動(dòng)縮放電路、電壓/電路變換電路和功率驅(qū)動(dòng)電路，最后輸出恒定電流。實(shí)驗(yàn)結(jié)果表明，恒流源輸出電流調(diào)節(jié)范圍為-45~+45 mA、精度為±0.1 mA，分辨率達(dá)0.024 4 mA，具有應(yīng)用靈活，外圍電路簡(jiǎn)單，可靠性高的特點(diǎn)。該數(shù)控直流恒流源也可為相關(guān)產(chǎn)品的測(cè)試系統(tǒng)研發(fā)提供參考。 Abstract: In order to solve the need to supply different values constant current for the magnetic amplifier in testing process， numerical control constant current source system was designed based on DAC7512 chip and microcontroller technology. The system used the AT89C51 as the main chip， which can convert the current control word from computer into to D/A control words. And the system wrote D/A control word into the DAC7512 chip to control the output voltage value by the SPI communication interface， which can output corresponding constant current figures by scaling circuit， the V/I converter and power drive circuit. Experimental results show that the current source output current Adjustment range is -45~+45mA， accuracy is ± 0.1mA， and resolution ratio is 0.024 4mA
