Embodiment Construction

[0030] Please refer to figure 1 . figure 1 It is a schematic diagram of an image acquisition system 100 with correction function disclosed in the first embodiment of the present invention. Such as figure 1 As shown, the image acquisition system 100 includes an image acquisition device 101 , a laser range finder 103 and a processor 105 , wherein the image acquisition device 101 and the laser range finder 103 are coupled to the processor 105 . The image acquisition device 101 includes two image acquirers 1011, 1013, wherein the image acquirers 1011, 1013 are used to acquire two images, such as a left-eye image LI and a right-eye image RI. However, the present invention is not limited to the fact that the image acquisition device 101 includes two image acquirers 1011 and 1013 . That is to say, the image capture device 101 may include at least two image capture devices.

[0031] Please refer to figure 2 . figure 2 is a schematic diagram illustrating the left-eye image LI a...

Abstract

An image capture system with calibration function includes an image capture device, a laser rangefinder, and a processer. The image capture device captures two images. The processer determines at least one feature point according to the two images, and generates depth information corresponding to each feature point of the at least one feature point according to the two images, wherein the laser rangefinder measures a reference distance corresponding to the each feature point, and the processer optionally calibrates the depth information or the two images according to the reference distance. Therefore, compared with the prior art, the calibration can be carried out more quickly and conveniently.

Description

technical field [0001] The invention relates to an image acquisition system, in particular to an image acquisition system with a correction function. Background technique [0002] In the prior art, a stereoscopic image acquisition device is often installed on a drone or a car to measure the distance between the drone or the car and surrounding objects. However, the mechanical accuracy required for the stereoscopic image acquisition device may vary depending on the usage environment or usage method of the stereoscopic image acquisition device (for example, the usage environment or usage method of the stereoscopic image acquisition device may cause the stereoscopic image acquisition device to The position of the left / right eye image acquirer or the angle of the acquired image changes) and cannot be maintained, so that the stereoscopic image acquisition device needs to be corrected. However, the calibration method disclosed in the prior art mainly utilizes a specific calibrati...
