Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] For laser depth cameras in the prior art, different cameras have different modes. For example, the cameras in the background art list have three modes, and different modes correspond to different detection ranges. Once the camera is configured, its detection range is determined, and it can only be obtained for different modes. For example, when the range2 mode is selected, only the detection range of 0.8m-4.4m can be obtained. When the actual application needs the detection range When the range is 0.5m-4.4m, a single range mode cannot meet the measurement needs.

Abstract

The invention belongs to the technical field of depth cameras, and particularly relates to a laser depth camera, a method and device for expanding the detection range of the laser depth camera, equipment and a storage medium, and the method comprises the steps: setting an output mode of the camera according to a required detection range; selecting a fusion threshold according to the set output mode; dividing the detection range of the output mode corresponding to the fusion threshold into different fusion regions according to the fusion threshold; and determining a depth value of the fusion region, and generating a depth image corresponding to the required detection range. According to the invention, the depth image with a wider depth value range can be obtained by fusing the depth images in different modes, so that the purpose of expanding the detection range of the laser depth camera is achieved. In addition, by using an existing camera configuration mode, the problem that a single range mode cannot meet the measurement requirement is solved. Moreover, the method gives consideration to the calculation speed and the image quality, is very suitable for being applied to a camera, becomes a fixed photographing mode, and is convenient and practical.

Description

technical field [0001] The invention belongs to the technical field of depth cameras, and in particular relates to a laser depth camera and a method, device, equipment and storage medium for expanding its detection range. Background technique [0002] The depth camera for distance measurement based on TOF (Time-of-Flight) method emits infrared light, which is reflected back to the sensor when it encounters an object. The camera calculates the distance value of the object by calculating the time difference between light emission and return. Based on the different principles of laser ranging, different laser parameters determine different detection ranges. For example, in the method based on the laser pulse principle, different pulse widths and laser intensities determine the range of testable distances. The following table shows the different modes of a camera and their corresponding ranging ranges: [0003] range number distance range range 0 0.5m-1.5m ...
