Embodiment 1

[0036] This embodiment provides a kind of calibration system for intelligent tracking camera module 2, such as Figure 7 As shown, the calibration system includes a calibration beam module 1, an intelligent tracking camera module 2, a control module 4, and a data integration module 3; the intelligent tracking camera module 2 is an internal component in an autostereoscopic display system, including a fixed tooling camera Match the spatial dimensions of the multi-degree-of-freedom detection device; the autostereoscopic display system uses a dual-camera system; wherein in this embodiment, the control module 4 and the data integration module 3 also directly use the internal components of the autostereoscopic display system without additional purchases these modules;

[0037] In the autostereoscopic display system, the position of the audience is detected in real time through the intelligent tracking camera module 2. Once the audience moves, the system will immediately adjust the p...

Embodiment 2

[0052] This embodiment 2 is a modification example of embodiment 1, the difference is that the light rod 11 in the calibration light rod module 1 is replaced by a light rod 13 with an appropriate length, such as Figure 5 As shown, it is only necessary to make it meet the requirement that it can emit extremely fine continuous light, that is, the effect obtained by the combination of the LED lamp array and the linear diffusion sheet 113 in Embodiment 1 is equivalent.

Embodiment 3

[0054] This embodiment 3 is based on the description of the calibration process for the calibration system for the intelligent tracking camera module 2 provided in embodiment 1. In this description, the LED backlight unit in the autostereoscopic display system is introduced together, but in the autostereoscopic display system The LED backlight unit does not belong to the content of the invention of the present invention; Image 6 As shown, the calibration process is as follows:

[0055] S1. System preparation: the calibration light column module 1, intelligent tracking camera module 2, data integration module 3 and control module 4 of the system enter the ready state; at this time, the calibration light column module 1 emits continuous light as a calibration image;

[0056] S2. The system lights up the LED backlight: the LED backlight unit of the system is composed of multiple columns of sequentially numbered LED units, and the control module 4 in the system lights up all the ...

Abstract

The invention discloses a calibration system for an intelligent tracking camera module. The calibration system comprises a calibration light column module, an intelligent tracking camera module and acontrol module; continuous light serving as a calibration image is formed by utilizing the calibration light column module; a calibration line of a camera is automatically divided through the intelligent tracking camera module; in each subsequent spatial position, the intelligent tracking camera module is used for identifying and positioning to obtain required spatial position data, and the control module is used for calling an existing calibration line to accurately calibrate the spatial position, so that accurate calibration of the intelligent tracking camera module can be realized. By meansof the calibration system, global domain calibration of the camera module can be achieved, meanwhile, spatial dimension matching of the multi-degree-of-freedom detection device is adopted, and the precision and accuracy of calibration are greatly improved.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a calibration system for an intelligent tracking camera module. Background technique [0002] With the continuous upgrading of new display technologies, the autostereoscopic display technology with more convenient, more comfortable and more universal working modes has gradually matured and attracted extensive attention from the industry. Autostereoscopic display technology mainly separates the existing images into left and right eye images, and through different technologies, when the observer observes the autostereoscopic display at a predetermined position along a predetermined direction, the left eye image enters the left eye, and the right eye image enters the right eye. Eyes, resulting in binocular parallax, a three-dimensional effect, and a free three-dimensional display effect. [0003] In the autostereoscopic display system, the position of the audience is d...
