Abstract: Techniques include calibrating the user-facing sensors using a calibration target in world space. A calibration target in this case includes an LED panel that is mounted on a linear rail, and a jig for mounting a head-mounted display (HMD) having user-facing sensors such that the user-facing sensors face the LED panel. On the HMD, there are at least two user-facing cameras; an eye-tracking (ET) camera and a face-tracking (FT) camera. There are also a plurality of LEDs associated with an ET camera. In some implementations, the LEDs surround the ET camera. The cameras are calibrated simultaneously—that is, the camera intrinsics and extrinsics relative to a base, i.e., the LED panel in a base position, are determined in a single step after data has been collected. In another, separate step, the ET camera LEDs are calibrated—that is, their positions relative to the ET camera are determined.

In the present disclosure, an amino acid skeleton of the amino acid derivative is modified mainly by a fluorescently-traceable functional group. 4-chloro-7-nitro-2,1,3-benzoxadiazole (NBD-Cl) has low polarity and strong fluorescence, and can be used to modify an N-terminal of the amino acid skeleton to conduct subcellular imaging. Moreover, the NBD-Cl has a relatively small volume, lacks reaction orthogonality, and causes little interference with biochemical reactions of the organism itself. The results of examples show that the fluorescently-traceable amino acid derivative has a desirable biological activity and can be fluorescently traced in vivo and in vitro.
