Please keep the program open while working)

三，校準(zhǔn)——漂移現(xiàn)象是因?yàn)樾?zhǔn)偏差引起

calibration-The foot slip phenomenon is caused by calibration deviation

打開校準(zhǔn)軟件Aximmetry Camera Calibrator（Open the calibration software Aximetry Camera Calibrator）

用FreeD協(xié)議連接（Connect using FreeD）

【管理設(shè)備】-【設(shè)備映射器】-【Camera Tracking-FreeD】-【新增】

輸入端口號(hào)和CameraID，與S80 to Axi的一致

（Enter the port number and CameraID, consistent with S80/DS80 to Axi）

1.鏡頭校準(zhǔn)（Lens calibration）

得到攝影機(jī)鏡頭的水平視角，中心偏移，畸變等數(shù)據(jù)的鏡頭文件

用Aximmetry的校準(zhǔn)軟件【Aximmetry Camera Calibrator】，官網(wǎng)購買

（Obtain the lens file of the camera's horizontal angle of view, center offset, distortion, and other data

Use Aximetry's calibration software [Aximetry Camera Calibrator], purchased on the official website）

https://my.aximmetry.com/User/WebShop

鏡頭校準(zhǔn)需要準(zhǔn)備一個(gè)55X40的校準(zhǔn)板，注意校準(zhǔn)板需要制作精準(zhǔn)

（A 55X40 calibration board needs to be prepared for lens calibration, please note that the calibration board needs to be made accurately）

進(jìn)入【Aximmetry Camera Calibrator】

新增鏡頭文件并命名

【視頻輸入】：選擇視頻輸入源，采集卡

【跟蹤設(shè)備】：選擇創(chuàng)建的Freed協(xié)議

然后【校準(zhǔn)鏡頭】

2.設(shè)置原點(diǎn)（Set Origin）

將校準(zhǔn)板的位置設(shè)置為虛擬場景的0，0，0

將Aximmetry標(biāo)準(zhǔn)的校準(zhǔn)本平放在機(jī)位前1-2米的地上

校準(zhǔn)板的字母需要在攝影機(jī)側(cè)

（Set the position of the calibration board to 0, 0, 0 in the virtual scene

Place the Aximetry standard calibration book flat on the ground 1-2 meters in front of the stand

The letters on the calibration board need to be on the camera side）

然后點(diǎn)擊【開始(Run)】（Then click on [Run]）

如有紅色提示，是雙目攝像頭無法識(shí)別校準(zhǔn)板，搖動(dòng)相機(jī)角度，直到完成

這一個(gè)是角度，就是攝影機(jī)與校準(zhǔn)版的Y軸角度，多機(jī)位時(shí)使用

（If there is a red prompt, it indicates that the binocular camera cannot recognize the calibration board. Shake the camera angle until it is complete

This one is the angle, which is the Y-axis angle between the camera and the calibration version, used when there are multiple positions）

3.跟蹤校準(zhǔn)（Tracking calibration）

使用軟件計(jì)算出跟蹤設(shè)備到攝影機(jī)傳感器之間的三個(gè)軸（XYZ）距離

跟蹤設(shè)備可以和攝影機(jī)不同朝向，根據(jù)實(shí)際使用情況朝上或朝下

軟件也是可以計(jì)算出來的

（Use software to calculate the three axis (XYZ) distance between the tracking device and the camera sensor

Tracking devices can be oriented differently from cameras, facing up or down according to actual usage

Software can also calculate）

這是朝上安裝的結(jié)果，有大的角度偏移

（This is the result of installing upwards, with a large angle deviation）

注意：在Aximmetry中加載鏡頭文件是會(huì)加載到跟蹤校準(zhǔn)的結(jié)果，如果加載到，畫面是會(huì)移動(dòng)一點(diǎn)或者旋轉(zhuǎn).

如果沒加載到，就需要在輸入窗口，原點(diǎn)模塊的【Delta Head Tranfs】手動(dòng)輸入

注意！這里是以米為單位，結(jié)果填進(jìn)來需要除以100

如：Delta Head位置，輸入：

Note: Loading a lens file in Aximetry will result in tracking and calibration. If loaded, the screen will move or rotate slightly

If it is not loaded, you need to manually input the Delta Head Tranfs in the origin module in the input window

be careful! This is in meters, and the result needs to be divided by 100

For example, Delta Head position, enter:

說明：因?yàn)檐浖男?zhǔn)也不是很精確的，所以會(huì)導(dǎo)致跟蹤結(jié)果并不完美，建議鏡頭校準(zhǔn)和跟蹤校準(zhǔn)都做多次，選擇平均的

Explanation: Because the calibration of the software is not very accurate, it can lead to imperfect tracking results. It is recommended to perform both lens calibration and tracking calibration multiple times and choose the average one.
