Embodiment Construction

[0049] During the process of filing this application, the applicant found that in the prior art, the approximate emission angle of the camera module is estimated by the manufacturing process parameters of the camera module (such as focal length, etc.), and there is a large deviation between the estimation accuracy and the actual test accuracy. In addition, the spot-itof module is a dot-array laser, not an area-array laser, which results in discontinuous pixels in the FOV effective area. Therefore, it is not possible to calculate the FOV simply by finding the outermost pixels in all directions. In other words, the existing technology Unable to perform test FOV calculations.

[0050] The embodiment of the present application solves the technical problem in the prior art that the test FOV cannot be calculated by providing a method for calculating the field of view.

[0051]The technical solution of the embodiment of the present application is to solve the above-mentioned technica...

Abstract

The invention discloses a field angle calculation method, terminal equipment and a storage medium. The method comprises the following steps: acquiring a shot image; determining a plurality of pixel areas in the shot image; determining a boundary inner side area according to a plurality of pixel areas in the shot image; and calculating a field angle of the camera module according to the boundary inner side area. According to the invention, the defect that FOV calculation cannot be carried out in the prior art can be solved, and rapid and convenient calculation of the field angle is realized.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method for calculating an angle of view, a terminal device and a storage medium. Background technique [0002] In order to improve the ranging range of the camera module, the spot indirect time-of-flight (spot-itof) camera module came into being, which is different from the area array indirect time-of-flight (itof ) mods are different. Specifically, the spot-itof module is dot-matrix pulse luminescence, each point has a higher luminous power and a lower operating frequency, and can test a longer distance. [0003] Among them, the light-emitting device of the spot-itof module is the laser pulse transmitting end, which is the key device of the spot-itof module, and must meet certain performance requirements during the manufacturing process. During the module testing process, one test is the field of vision (FOV) test, but currently there is no test method for t...
